TECHNICAL SPECIFICATIONS

GENERAL SAFETY INSTRUCTIONS
WARNING! Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool. SAVE THESE INSTRUCTIONS.

WORK AREA

• • Keep work area clean and well lit. Cluttered and dark areas invite accidents.
  • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

 ELECTRICAL SAFETY

• • Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.Unmodified plugs and matching outlets will reduce risk of electric shock
  • Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
  • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
  • Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
  • When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

PERSONAL SAFETY

• • Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury
  • Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
  • Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.
  • Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
  • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
  • Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
  • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust related hazards.

POWER TOOL USE AND CARE

• • Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
  • Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
  • Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
  • Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
  • Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
  • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
  • Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

SERVICE

• • Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

SAFETY INSTRUCTIONS FOR CIRCULAR SAWS

DANGER

• Keep hands away from cutting area and the blade; keep your second hand on front handle (if both hands are holding the saw, they can not be cut by the blade)
• Do not reach underneath the workpiece (the guard cannot protect you from the blade below the workpiece)
• Adjust the cutting depth to the thickness of the workpiece (less than a full tooth of the blade teeth should be visible below the workpiece)
• Never hold piece being cut in your hands or across your leg (it is important to support the work properly to minimise body exposure, blade binding, or loss of control)
• Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord (contact with a “live” wire will also make exposed metal parts of the tool “live” and shock the operator)
• When ripping always use a rip fence or straight edge guide (this improves the accuracy of cut and reduces the
  chance for blade binding)
• Always use blades with correct size and shape of arbor holes (diamond or round) (blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control)
• Never use damaged or incorrect blade washers or bolts (the blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation

KICKBACK – CAUSES

• Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator
• When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator
• If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top
  surface of the wood causing the blade to climb out of the kerf and jump back towards operator

KICKBACK – OPERATOR PREVENTION

Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below

• Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces; position your body to either side of the blade, but not in line with the blade (kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken)
• When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop; never attempt to remove the saw from the work or pull the saw backwards while the blade is in motion or kickback may occur (investigate and take corrective actions to eliminate the cause of blade binding; avoid cutting nails or screws)
• When restarting a saw in the workpiece, centre the saw blade in the kerf and check that saw teeth are not engaged into the material (if saw blade is binding, it may walk up or kickback from the workpiece as the saw is restarted)
• Support large panels to minimise the risk of blade pinching and kickback (large panels tend to sag under their own weight; supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel)
• Do not use a dull or damaged blade (unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback)
• Blade depth and bevel adjusting locking levers must be tight and secure before making cut (if blade adjustment shifts while cutting, it may cause binding and kickback)
• Use extra caution when making a plunge cut into existing walls or other blind areas (the protruding blade may cut objects that can cause kickback)

WARNING

• Check lower guard for proper closing before each use
• Do not operate the saw if lower guard does not move freely and close instantly
• Never clamp or tie the lower guard into the open position
• If saw is accidentally dropped, lower guard may be bent; raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut
• Check the operation of the lower guard spring; if the guard and the spring are not operating properly, they must be serviced before use (lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris)
• Lower guard should be retracted manually only for special cuts such as plunge cuts and compound cuts; raise lower guard by retracting handle and as soon as blade enters the material, the lower guard must be released (for all other sawing, the lower guard should operate automatically)
• Always observe that the lower guard is covering the blade before placing saw down on bench or floor (an unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path; be aware of the time it takes for the blade to stop after switch is released)
• Avoid damage that can be caused by screws, nails and other elements in your workpiece; remove them before
  you start cutting
• When you put away the tool, switch off the motor and ensure that all moving parts have come to a complete standstill
• Use completely unrolled and safe extension cords with a capacity of 16 Amps (U.K. 13 Amps)
• In case of jamming or electrical or mechanical malfunction, immediately switch off the tool and disconnect the plug
• SKIL can assure flawless functioning of the tool only when original accessories are used
• Use only accessories with an allowable speed matching at least the highest no-load speed of the tool
• Never use the tool without the original protection guard system
• This tool should not be used by people under the age of 16 years
• The noise level when working can exceed 85 dB(A); wear ear protection
• If the cord is damaged or cut through while working, do not touch the cord, but immediately disconnect the plug
• Never use tool when cord is damaged; have it replaced by a qualified person
• Always check that the supply voltage is the same as the voltage indicated on the nameplate of the tool (tools with a rating of 230V or 240V can also be connected to a 220V supply)
• This tool is not suitable for wet cutting
• After switching off your circular saw, never stop the rotation of the saw blade by a lateral force applied against it
• Never use circular saw blades made of high speed steel (HSS)
• Never use grinding/cutting discs with this tool
• Do not cut material containing asbestos
• Wear a dust protection mask when working with materials which produce dust that is detrimental to health; inform yourself beforehand about the materials to be worked on
• Do not attempt to cut extremely small workpieces
• Remove all obstacles on top of as well as underneath the cutting path before you start cutting
• Do not work overhead with the tool
• Only use a saw table provided with a switch that prevents restarting of the motor after interruption of voltage
