EXHAUST HAZARD:
Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Do not operate this equipment in a closed building.
EQUIPMENT MISUSE HAZARD:
Misuse of pressure washer or accessories can cause the equipment to rupture or malfunction and result in serious injury.
DDo not alter or modify any part or
DCheck equipment daily. Repair or replace worn or damaged parts immediately.
DDo not exceed maximum working pressure (MWPR) of the
DUse fluids and solvents that are compatible with the equipment wetted parts. See Specifications page for this information.
DWear hearing protection when operating this equipment.
DDo not ???blow back??? fluid; this is not an air spray system
DFollow Pressure Relief, page 7 before cleaning, checking or servicing equipment.
TOXIC FLUID HAZARD:
Hazardous fluid or toxi fumes can cause serious injury or death if splashed in eyes or on skin, inhaled, or swallowed.
D Know specific hazards of fluids you are using and take protective measures as recommended by the fluid and solvent manufacturer.
SKIN INJECTION HAZARD:
Spray from gun, leaks or ruptured components can inject fluid into your body and cause serious injury. Fluid splashed in eyes or on skin can also cause serious injury.
DFluid injected into skin might look like just a cut, but it is a serious injury. Get immediate surgical treatment.
DDo not point gun at anyone or any part of the body.
D Do not stop or deflect leaks with hand, body, glove, or rag.
DDo not put your hand or fingers over the spray tip.
DTIghten fluid connections before you start this equipment.

Connect to Water Supply
Connect hose with at least a 3/4 in. (19 mm) ID from water supply to 3/4 in. garden hose inlet on the pressure washer. The supply hose should not be more than 50 ft (15 m) long.
Note: Water source must have a minimum flow rate equal to that of pressure washer.

PRESSURE RELIEF
Follow these instructions whenever you are instructed to relieve pressure, stop spraying for
more than 10 minutes, check or service the equipment, or install or clean the spray nozzle.
1. Engage trigger safety latch

2. Turn pressure washer off
3. Remove ignition cable from spark plug.
4. Shut off water supply. Disconnect from water.
5. Disengage trigger safety latch. Trigger gun to relieve pressure. Then

Operation
Startup
Always use this startup procedure to ensure that the pressure washer is started safely and properly.
DAlways engage gun trigger safety latch when you stop spraying. This reduces the risk of fluid injection or splashing in eyes or on skin if gun is bumped or accidentally triggered.
DAlways observe the CAUTIONS in this section to avoid costly damage to pressure washer.
DIf you use the Sandblaster Kit, see Sandblaster Kit Manual for detailed cleaning information.
1.Check oil level. of engine.
2. Check fuel level.
3. Turn on water supply.
CAUTION
Never run pressure washer without wa- ter. Costly pump damage will result. Always be sure water supply is complete- ly turned on before you run pressure washer.
8 309828
4. Trigger gun until a constant stream of water sprays from tip indicating air is purged from the system.
5. Be sure spark plug ignition cable is pushed firmly onto spark plug.
ti3242a
ti3240a
7.Pull the starter rope quickly to start the engine. Pull and return the rope until the engine starts. HINT: Placing one foot on the pres- sure washer as a brace provides better leverage.
NOTE: For easier starting, have one person start pressure washer while another triggers gun.
CAUTION
DDo not allow pressure washer to idle more than 10 minutes. This causes circulating water to overheat and serious damage to the pump. The pump is equipped with a thermal valve to help prevent severe damage if circulating water is overheating.
DTurn off pressure washer if it will not be spraying at least every 10 minutes or if thermal valve activates. If heated inlet water is used, reduce this time.
DDo not operate pressure washer with inlet water screen removed. This screen helps keep abrasive sediment which could clog pump or damage cylinders, out of pump.
DDo not pump caustic materials.
309828 9
Trigger Safety Latch
Always engage the safety latch when you stop spraying.
Always engage trigger safety latch when you stop spraying even for a moment. The engaged safety latch prevents the gun from being triggered accidentally by hand or when dropped or bumped. Be sure latch is pushed fully down or it will not prevent the gun from being triggered.
