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, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum- based products, penetrating lubricants, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which could 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 opera- tion 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 Figure 21.
Excessive pump pressure (a pulsing sensation felt while squeezing the trigger) may be the result of a clogged or dirty nozzle.
nTurnoff the pressure washer and shut off the water supply. Pull trigger to release water pressure.
nRemove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
nUsinga straightened paper clip or nozzle cleaning tool
(not provided), free any foreign materials clogging or restricting the nozzle.
nUsinga 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.
CLEANING THE AIR FILTER
See Figure 22.
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 tabs 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.
nBrush the air filter lightly to clean.
nReinstall 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.
nReinstall the air filter cover.
CHECKING SPARK PLUG
See Figure 23.
nClean the area around the base of the spark plug before removing to keep dirt and debris out of the engine. Re- move spark plug.
nClean off carbon deposits on the spark plug electrode us- ing a plug cleaner or wire brush. Replace the plug if worn. (Recommended spark plug: NGK BPRGE5 or equivalent.)
nCheck electrode gap. The gap should be .028 in.
nReinstall spark plug. Tighten securely.
CHANGING ENGINE LUBRICANT
See Figure 24.
nShut off the engine.
nClean the area around the oil cap/dipstick, then remove the oil cap/dipstick.
nTilt the pressure washer on its side as shown. Drain lu- bricant into approved container.
