MAINTENANCE
WARNING:
When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.
WARNING:
Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury.
WARNING:
Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to stop, and discon- nect spark plug wire and move it away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage.
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.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum- based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.
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:
nCheck that all bolts, nuts, etc., are securely tightened.
nMake sure the air filter is clean.
nCheck both the engine lubricant level and the fuel tank level; refill as needed.
nInspect the work area for hazards.
nIf there is excessive noise or vibration, stop the unit immediately.
nozzle maintenance
See Figures 28 - 30.
Excessive pump pressure (a pulsing sensation felt while squeezing the trigger) may be the result of a clogged or dirty nozzle.
nTurn off the pressure washer and shut off the water supply. Point nozzle in a safe direction and pull trigger to release water pressure.
nRemove the nozzle from the spray wand. NOTE: Never point the spray wand at your face.
nUsing a straightened paper clip or nozzle cleaning tool, free any foreign materials clogging or restricting the nozzle.
nUsing a garden hose, flush debris out of nozzle by back flushing (running the water through the nozzle backwards or from the outside to the inside).
nReconnect the nozzle to the spray wand.
nTurn on the water supply and start the engine.
To clean nozzles on surface cleaner:
nTurn off the pressure washer and shut off the water supply. With the surface cleaner on the ground, pull trig- ger to release water pressure.
nDisconnect surface cleaner from spray wand.
nUnscrew the retaining nut and remove the nozzle from the spray bar.
NOTE: Never point the spray bar at your face.
nUsing a straightened paper clip or nozzle cleaning tool (not provided), free any foreign materials clogging or restricting the nozzle.
nUsing a garden hose, flush debris out of nozzle by back flushing (running the water through the nozzle backwards or from the outside to the inside).
nReinsert the nozzle into the spray bar, being careful not to damage the
NOTE: Make sure the flats of the nozzle are aligned with the flats in the spray bar openings and the groove in the nozzle is in the same orientation as the spray bar itself as shown.
nReinstall the retaining nut and torque to
nReconnect the surface cleaner to the spray wand.
nTurn on the water supply and start the pressure washer.
cleaning the air filter
See Figure 31.
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.
nPush the tab on the air filter cover to open, then remove the air filter cover.
nLift the edge of the air filter carefully and pull it out.
nLightly tap or blow out dirt particles from filter.
