SAFETY INSTRUCTIONS

EYE PROTECTION which conforms to ANSI specifications and provides protection against flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when connecting to air supply, loading, operating or servicing this tool. Eye protection is required to guard against flying fasteners and debris, which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn. Eye protection equipment must conform to the requirements of the American National Standards Institute, ANSI Z87.1 and provide both frontal and side protection.

NOTE: Non-side shielded spectacles and face shields alone do not provide adequate protection.

CAUTION: Additional Safety Protection will be required in some environments. For example, the working area may include exposure to noise level which can lead to hearing damage. The employer and user must ensure that any necessary hearing protection is provided and used by the operator and others in the work area. Some environments will require the use of head protection equipment. When required, the employer and user must ensure that head protection conforming to ANSI Z89.1 is used.

AIR SUPPLY AND CONNECTIONS

WARNINGS

• Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as tool may explode, possibly causing injury.
• Do not use supply sources which can potentially exceed 200 P.S.I.G. as tool may burst, possibly causing injury.
• The connector on the tool must not hold pressure when the air supply is disconnected. If a wrong fitting is used, the tool can remain charged with air after disconnecting and thus will be able to drive a fastener even after the air line is disconnected possibly causing injury.
• Do not pull the trigger or depress the contact arm while connected to the air supply as the tool may cycle, possibly causing injury.
• Always disconnect the air supply:
  1. Before making adjustments;
  2. When servicing the tool;
  3. When clearing a jam;
  4. When the tool is not in use;
  5. When moving to a different work area, accidental actuation may occur, possibly causing injury.

LOADING TOOL

WARNINGS

• When loading tool:
  1. Never place a hand or any part of the body in the fastener discharge area of the tool;
  2. Never point the tool at anyone;
  3. Do not pull the trigger or depress the trip as accidental actuation may occur, possibly causing injury.

OPERATION

WARNINGS

• Always handle the tool with care:
  1. Never engage in horseplay;
  2. Never pull the trigger unless your nose is directed toward the work;
  3. Keep others a safe distance from the tool while the tool is in operation as accidental actuation may occur, possibly causing injury.
• The operator must not hold the trigger pulled on contact arm tools except during fastening operation as serious injury could result if the trip accidentally contacted someone or something, causing the tool to cycle.
• Keep hands and body away from the discharge area of the tool. A contact arm tool may bounce from the recoil of driving a fastener and an unwanted second fastener may be driven possibly causing injury.
• Check the operation of the contact arm mechanism frequently. Do not use the tool if the arm is not working correctly as accidental driving of a fastener may result. Do not interfere with the proper operation of the contact arm mechanism.
  Do not drive fasteners on top of other fasteners or with the tool at an overly steep angle as this may cause deflection of fasteners which could cause injury.
• Do not drive fasteners close to the edge of the workpiece as the wood may split, allowing the fastener to be deflected possibly causing injury.
• This nailer produces SPARKS during operation. NEVER use the nailer near flammable substances, gases, or vapors including lacquer, paint, benzine, thinner, gasoline, adhesives, mastics, glues or any other material that is — or the vapors, fumes, or byproducts of which are — flammable, combustible or explosive. Using the nailer in any such environment could cause an EXPLOSION resulting in personal injury or death to the user and bystanders.

MAINTAINING THE TOOL

WARNINGS

When working on air tools note the warnings in this manual and use extra care when evaluating problem tools.

S32 TOOL SPECIFICATIONS

All screws and nuts are metric.

FASTENER SPECIFICATIONS:

TOOL AIR FITTING:

This tool uses a free-flow connector plug, 1/4” N.P.T. The minimum inside diameter should be .190″ (4.8mm). The fitting must be capable of discharging tool air pressure when disconnected from the air supply.

OPERATING PRESSURE:

The operating pressure of the S32 tool is 60 to 100 p.s.i. (4.2 to 7.1 kg/cm2). Select the operating pressure within this range for best fastener performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.

AIR CONSUMPTION:

Model S32 requires 2.1 cubic feet per minute (.0582 cubic meters) of free air to operate at the rate of 100
fasteners per minute, at 80 p.s.i. (5.6kg/cm2). Take the actual rate at which the tool will be run to determine the amount of air required. For instance, if your fastener usage averages 50 fasteners per minute, you need 50% of the tool’s c.f.m. of free air which is required for running at 100 fasteners per minute.

OPERATION

BOSTITCH OFFERS THREE TYPES OF OPERATION FOR THIS SERIES TOOL.

CONTACT TRIP:

The common operating procedure on “Contact Trip” tools is for the operator to contact the work to actuate the trip mechanism while keeping the trigger pulled, thus driving a fastener each time the work is contacted. This will allow rapid fastener placement on many jobs, such as sheathing, decking and pallet assembly. All pneumatic tools are subject to recoil when driving fasteners. The tool may bounce, releasing the trip, and if unintentionally allowed to recontact the work surface with the trigger still actuated (finger still holding trigger pulled) an unwanted second fastener will be driven.

SEQUENTIAL TRIP:

The Sequential Trip requires the operator to hold the tool against the work before pulling the trigger. This makes accurate fastener placement easier, for instance on framing, toe-nailing and crating applications.The Sequential Trip allows exact fastener location without the possibility of driving a second fastener on recoil, as described under “Contact Trip”. The Sequential Trip Tool has a positive safety advantage because it will not accidentally drive a fastener if the tool is contacted against the work – or anything else – while the operator is holding the trigger pulled.

DUAL TRIGGER OPERATED:

The trigger-operated model is cycled by the actuation of two triggers. This model does not have a Contact Arm and is intended for use only where a Contact Arm CANNOT be used to satisfy the requirements of the application. The Dual Trigger Operated tool will cycle each time the triggers are actuated.

CAUTION: The secondary trigger must be installed properly and be functioning correctly. Without the secondary trigger the dual trigger functionality will be defeated and the tool will operate as a trigger fire tool only.

MODEL IDENTIFICATION:

Refer to Operation Instructions on page 7 before proceeding to use this tool.

AIR SUPPLY AND CONNECTIONS

WARNING: Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as tool may explode, possibly causing injury.

FITTINGS:

Install a male plug on the tool which is free flowing and which will release air pressure from the tool when disconnected from the supply source.

HOSES:

Air hoses should have a minimum of 150 p.s.i. (10.6 kg/cm2) working pressure rating or 150 percent of the maximum pressure that could be produced in the air system. The supply hose should contain a fitting that will provide “quick disconnecting” from the male plug on the tool.

SUPPLY SOURCE:

Use only clean regulated compressed air as a power source for this tool. NEVER USE OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES, AS A POWER SOURCE FOR THIS TOOL MAY EXPLODE.

REGULATOR:

A pressure regulator with an operating pressure of 0 – 125 p.s.i. (0 – 8.79 kg/cm2) is required to control the operating pressure for safe operation of this tool. Do not connect this tool to air pressure which can potentially exceed 200 p.s.i. (14 kg/cm2) as tool may fracture or burst, possibly causing injury.

OPERATING PRESSURE:

Do not exceed the recommended maximum operating pressure as tool wear will be greatly increased. The air supply must be capable of maintaining the operating pressure at the tool. Pressure drops in the air supply can reduce the tool’s driving power. Refer to “TOOL SPECIFICATIONS” for setting the correct operating pressure for the tool.

FILTER:

Dirt and water in the air supply are major causes of wear in pneumatic tools. A filter will help to get the best performance and minimum wear from the tool. The filter must have adequate flow capacity for the specific installation. The filter has to be kept clean to be effective in providing clean compressed air to the tool. Consult the manufacturer’s instructions on proper maintenance of your filter. A dirty and clogged filter will cause a pressure drop which will reduce the tool’s performance.

LUBRICATION

Frequent, but not excessive, lubrication is required for best performance. Oil added through the air line connection will lubricate the internal parts. Use BOSTITCH Air Tool Lubricant, Mobil Velocite #10, or equivalent. Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seals and bumpers in the tool, resulting in poor tool performance and frequent tool maintenance.
If no airline lubricator is used, add oil during use into the air fitting on the tool once or twice a day. Only a few drops of oil at a time is necessary. Too much oil will only collect inside the tool and will be noticeable in the exhaust cycle.

COLD WEATHER OPERATION:

For cold weather operations, near and below freezing, the moisture in the air line may freeze and prevent tool operation. We recommend the use of BOSTITCH WINTER FORMULA air tool lubricant or permanent antifreeze (ethylene glycol) as a cold-weather lubricant.

CAUTION: Do not store tools in a cold weather environment to prevent frost or ice formation on the
tools operating valves and mechanisms that could cause tool failure.

NOTE: Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use these low temperature air dryers without checking compatibility.

LOADING THE S32

EYE PROTECTION which conforms to ANSI specifications and provides protection against flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when connecting to air supply, loading, operating or servicing this tool. Eye protection is required to guard against flying fasteners and debris, which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn. Eye protection equipment must conform to the requirements of the American National Standards Institute, ANSI Z87.1 and provide both frontal and side protection.

NOTE: Non-side shielded spectacles and face shields alone do not provide adequate protection.

TO PREVENT ACCIDENTAL INJURIES:

• Never place a hand or any other part of the body in the nail discharge area of the tool while the air supply is connected.
• Never point the tool at anyone else.
• Never engage in horseplay.
• Never pull the trigger unless your nose is directed at the work.
• Always handle the tool with care.
• Do not pull the trigger or depress the trip mechanism while loading the tool.

1. Disengage the latch and pull back on the staple guide unit.
2. Insert the staples into the magazine. CAUTION: Load with points upward.
3. Push the staple guide unit closed, until the latch engages.
   NOTE: Use only fasteners recommended by Bostitch for S32 series staplers, or fasteners which meet Bostitch specifications.

BEFORE HANDLING OR OPERATING THIS TOOL:

1. READ AND UNDERSTAND THE WARNINGS CONTAINED IN THIS MANUAL.
2. REFER TO “TOOL SPECIFICATIONS” IN THIS MANUAL TO IDENTIFY THE OPERATING SYSTEM ON YOUR TOOL.

There are three available systems on BOSTITCH pneumatic tools. They are:

1. DUAL TRIGGER OPERATION
2. CONTACT TRIP OPERATION
3. SEQUENTIAL TRIP OPERATION

OPERATION

DUAL TRIGGER OPERATION:

A DUAL TRIGGER OPERATED tool requires two actions to drive a fastener. Each time both triggers are pulled the tool will drive a fastener. The dual trigger operated model is intended for use only when a contact trip or sequential trip cannot be used due to the requirements of the application.

CAUTION: The secondary trigger must be installed properly and be functioning correctly. Without the
secondary trigger the dual trigger functionality will be defeated and the tool will operate as a trigger fire
tool only.

CONTACT TRIP OPERATION:

The CONTACT TRIP MODEL tool contains a contact trip that operates in conjunction with the trigger to
drive a fastener. There are two methods of operation to drive fasteners with a contact trip tool.

• SINGLE FASTENER PLACEMENT: To operate the tool in this manner, first position the contact trip on the work surface, WITHOUT PULLING THE TRIGGER. Depress the contact trip until the nose touches the work surface and then pull the trigger to drive a fastener. Do not press the tool against the work with extra force. Instead, allow the tool to recoil off the work surface to avoid a second unwanted fastener. Remove your finger from the trigger after each operation.
• BRAPID FASTENER OPERATION: To operate the tool in this manner, hold the tool with the contact trip pointing towards but not touching the work surface. Pull the trigger and then tap the contact trip against the work surface using a bouncing motion. Each depression of the contact trip will cause a fastener to be driven.

WARNINGS:

• The operator must not hold the trigger pulled on contact trip tools except during fastening operation, as serious injury could result if the trip accidentally contacts someone or something, causing the tool to cycle.
• Keep hands and body away from the discharge area of the tool. A contact trip tool may bounce from the recoil of driving a fastener and an unwanted second fastener may be driven, possibly causing injury.

SEQUENTIAL TRIP OPERATION:

The SEQUENTIAL TRIP MODEL contains a contact trip that operates in conjunction with the trigger to drive a fastener. To operate a sequential trip tool, first position the contact trip on the work surface WITHOUT PULLING THE TRIGGER. Depress the contact trip and then pull the trigger to drive a fastener. As long as the contact trip is contacting the work and is held depressed, the tool will drive a fastener each time the trigger is depressed. If the contact trip is allowed to leave the work surface, the sequence described above must be repeated to drive another fastener.

TOOL OPERATION CHECK

CAUTION: Remove all fasteners from the tool before performing the tool operation check.

DUAL TRIGGER OPERATED TOOL:

• With fingers of the triggers, hold the tool with a firm grip on the handle.
• Place the nose of the tool against the work surface.
• First, pull the secondary trigger and then pull the primary trigger to drive. Release the triggers and the cycle is complete.

CAUTION: THE TOOL WILL CYCLE EACH TIME THE TRIGGER IS PULLED!
CAUTION: The secondary trigger must be installed properly and be functioning correctly. Without the secondary trigger the dual trigger functionality will be defeated and the tool will operate as a trigger fire tool only.

CONTACT TRIP OPERATION

• With finger off the trigger, press the contact trip against the work surface.
  THE TOOL MUST NOT CYCLE.
• Hold the tool off the work surface, and pull the trigger.
  THE TOOL MUST NOT CYCLE.
• With the tool off the work surface, pull the trigger. Press the contact trip against the work surface.
  THE TOOL MUST CYCLE.
• Without touching the trigger, press the contact trip against the work surface, then pull the trigger.
  THE TOOL MUST CYCLE.

SEQUENTIAL TRIP OPERATION

• Press the contact trip against the work surface, without touching the trigger.
  THE TOOL MUST NOT CYCLE.
• Hold the tool off the work surface and pull the trigger.
  THE TOOL MUST NOT CYCLE.
  Release the trigger. The trigger must return to the trigger stop on the frame.
• Pull the trigger and press the contact trip against the work surface.
  THE TOOL MUST NOT CYCLE.
• With finger off the trigger, press the contact trip against the work surface. Pull the trigger.
  THE TOOL MUST CYCLE.

IN ADDITION TO THE OTHER WARNINGS CONTAINED IN THIS MANUAL OBSERVE THE FOLLOWING FOR SAFE OPERATION

• Use the BOSTITCH pneumatic tool only for the purpose for which it was designed.
• Never use this tool in a manner that could cause a fastener to be directed toward the user or others in the work area.
• Do not use the tool as a hammer.
• Always carry the tool by the handle. Never carry the tool by the air hose.
• Do not alter or modify this tool from the original design or function without approval from BOSTITCH, INC.
• Always be aware that misuse and improper handling of this tool can cause injury to yourself and others.
• Never clamp or tape the trigger or contact trip in an actuated position.
• Never leave a tool unattended with the air hose attached.
• Do not operate this tool if it does not contain a legible WARNING LABEL.
• Do not continue to use a tool that leaks air or does not function properly. Notify your nearest Bostitch representative if your tool continues to experience functional problems.

MAINTAINING THE PNEUMATIC TOOL

WARNING: When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.

CAUTION: Pusher spring (constant force spring). Caution must be used when working with the spring assembly. The spring is wrapped around, but not attached to a roller. If the spring is extended beyond its length, the end will come off the roller and the spring will roll up with a snap, with a chance of pinching your hand. Also, the edges of the spring are very thin and could be cut. Care must also be taken to insure no permanent kinks are put in the spring as this will reduce the spring’s force.

REPLACEMENT PARTS:

BOSTITCH replacement parts are recommended. Do not use modified parts or parts which will not give
equivalent performance to the original equipment.

ASSEMBLY PROCEDURE FOR SEALS:

When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE or
equivalent on all “O”-rings. Coat each “O”-ring with “O”-LUBE before assembling. Use a small amount of oil on all moving surfaces and pivots. After reassembly add a few drops of BOSTITCH Air Tool Lubricant through the air line fitting before testing.

AIR SUPPLY PRESSURE AND VOLUME:

Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersize fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent the tool from receiving an adequate volume of air, even though the pressure reading is high. The results will be slow operation, misfeeds or reduced driving power. Before evaluating tool problems for these symptoms, trace the air supply from the tool to the supply source for restrictive connectors, swivel fittings, low points containing water, and anything else that would prevent full volume flow of air to the tool.
