BRIGGS & STRATTON ENGINE
This Briggs & Stratton 500 Series engine enables the pressure washer to achieve 2,200 PSI (pounds per square inch) at a rate of 2.0 GPM (gallons per minute).
FUEL TANK
This fuel tank has a maximum capacity of 1 quart (.95 liters). Use unleaded automotive gasoline in the engine.
HOSE STORAGE
Once the high-pressure hose is rolled, hang it on the front of the machine using the hook and loop strap for convenient storage.
OFF SWITCH
To turn the engine off, press and hold the OFF switch for a full three seconds or until the engine stops.
RECOIL STARTER
The recoil starter is pulled to start the machine.
SPRAY WAND
The spray wand has a gripping surface that provides added control of the spray wand and helps reduce fatigue. Both the spray wand and extension have storage areas located
on top of the machine.
THERMAL RELIEF VALVE
This pump feature will prevent water temperatures from reaching harmful levels by releasing a small amount of water from a rubber hose. Once the water has drained, the thermal relief valve will reset itself.
TRIGGER WITH LOCK OUT
Pulling the trigger releases a stream of water for high-pressure cleaning. The lockout protects against unauthorized use.

• Lift the machine and slide the combination into the wheel mounting hole in the machine base as shown.
• Push the hitch pin into the hole on the end of the axle to secure the wheel assembly. NOTE: The hitch pin should be pushed into the axle until the center of the pin rests on top of the axle.
• Repeat with the second wheel.

INSTALLING THE TELESCOPING HANDLE See Figure 3.
To install the telescoping handle:

• Align the arrows on the U-shaped handle with the arrows on the back of the frame.
• Push and hold the button on the handle as you slide the handle into the holes in the frame.
• Lock the handle in place by aligning the slot in the handle lock cap with the pin on the housing bar. Next, push the handle lock cap down while turning the cap clockwise. NOTE: Before use, pull the handle up until the lock button snaps through the locking slot to secure the handle in place.

ADDING OIL TO THE ENGINE

• Place the pressure washer on a flat, level surface.
• Unscrew the oil cap/dipstick by turning counterclockwise.
• Using 4-stroke engine oil (SAE 30), fill to the upper level of the oil filter neck (18 oz., 4-cycle engine oil provided).
• Replace the oil cap/dipstick and securely tighten.

ADDING GASOLINE TO THE FUEL TANK

When adding gas to the pressure washer, make sure the unit is sitting on a flat, level surface. If the engine is hot, let the pressure washer cool before adding gas. ALWAYS fill the fuel tank outdoors with the machine turned off. NOTE: Use unleaded gas only. DO NOT mix oil with gas.

• Before removing the fuel cap, clean the area around it. Remove the fuel cap.
• Insert a clean funnel into the fuel tank, then slowly pour gasoline into the tank. Fill the tank to approximately 1-1/2 in. below the top of the tank neck (this allows for
  fuel expansion).
• Replace the fuel cap and tighten securely.
• Clean up any spills before starting the engine.

ATTACHING INJECTION HOSE
See Figure 6. Before detergent can be used with this machine, the injection hose must be attached.

• Push the open end of the clear injection hose securely over the fitting as shown in Figure 6.
• Place the filtered end of the injection hose in the bottle of detergent

ASSEMBLING THE SPRAY WAND
See Figure 7.
To attach the spray wand extension:

• Place the threaded end of the wand extension in the connector on the end of the spray wand assembly.
• Turn the connector clockwise until it stops. This secures the wand extension in place.
• When not in use, remove the spray wand extension from the spray wand by turning the connector counterclockwise. When not in use, store both pieces on top of the
  pressure washer.

CONNECTING HIGH-PRESSURE HOSE TO SPRAY WAND ASSEMBLY
See Figure 8.

• Screw the collar on the high-pressure hose into the spray wand’s inlet coupler by turning the hose collar clockwise.
• Pull on the hose to be certain it is properly secured.

OPERATION

APPLICATIONS
You may use this tool for the purposes listed below:

• Removing dirt and mold from decks, cement patios, and house siding
• Cleaning cars, boats, motorcycles, outdoor furniture, and grills

STARTING AND STOPPING THE PRESSURE WASHER

Before starting the engine:

• Connect all hoses.
• Check all fluids (oil and gas).
• Turn the garden hose on, then squeeze the trigger to relieve air pressure; hold the trigger until a steady stream of water appears.

To start the engine:

• Push the primer bulb 3 times. NOTE: If starting the engine for the first time, push the primer bulb 5 times.
• Grasp the recoil starter and pull slowly until resistance is felt. Give the recoil starter a short, brisk pull to start the engine.

To stop the engine:
On top of the engine is an OFF ( O ) switch. Press and hold the switch in the OFF position for three (3) seconds or until the engine stops.

USING THE SPRAY WAND TRIGGER
See Figure 13. For greater control and safety, keep both hands on the spray wand at all times.

• Pull back and hold the trigger to operate the pressure washer.
• Release the trigger to stop the flow of water through the nozzle.

To engage the lockout:

• Push up on the lockout until it clicks into the slot.

To disengage the lockout:

• Push the lock out down and into its original position. For the most effective cleaning, the spray nozzle should be between 8 in. and 24 in. from the surface to be cleaned. If the spray is too close, it can damage the cleaning surface.

SELECTING THE RIGHT QUICK-CONNECT NOZZLE FOR THE JOB
See Figure 14 – 15. �Before starting any cleaning job, determine the best nozzle for the job. Each of the three nozzles has a different spray pattern. The nozzle patterns are: detergent (low pressure), 25˚ (medium pressure), and 0˚ (high pressure). NOTE: For a gentle rinse, select the detergent nozzle. Scouring the surface requires a more direct spray of water. Select the 0˚ nozzle for tough jobs. �Apply detergent using the detergent nozzle.

MAINTENANCE

GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts should be replaced at an authorized service center. Before running the engine, perform the following pre-operation steps:

• Check that all bolts, nuts, etc., are securely tightened.
• Make sure the air filter is clean.
• Check both the engine oil level and the fuel tank level; refill as needed.
• Inspect the work area for hazards.
• If there is excessive noise or vibration, stop the unit immediately.

CLEANING THE AIR FILTER
See Figure 18. A dirty air filter will cause starting difficulty, loss of performance, and shorten the life span of the engine. Check the air filter monthly. For best performance, replace the air filter at least once a year.

• Using the hole in the shroud for easy access, remove the air filter screw.
• Remove the air filter cover.
• Lift the edge of the air filter carefully and pull it out.
• Wash the air filter with warm, soapy water.
• Rinse and squeeze to dry.
• Put a small amount of motor oil (SAE 30) on the filter sponge. Squeeze out the excess oil, then reinstall the air filter. NOTE: Make sure the filter is seated properly inside the cover. Installing the filter incorrectly will allow dirt to enter the engine, causing rapid engine wear.
• Reinstall the air filter cover and tighten securely using the air filter screw.
