MAINTENANCE
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 the 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).
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.
nRotate air filter knob
nLift the edge of the air filter carefully and pull it out.
nLightly tap or blow out dirt particles from filter.
nReinstall the air filter and cover.
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.
CHANGING ENGINE LUBRICANT
See Figure 32.
nShut off the engine.
nClean the area around the lubricant fill cap/dipstick, then remove the lubricant fill cap/dipstick.
nTilt unit and drain.
nDrain lubricant into approved container.
NOTE: Drain the lubricant while the engine is still warm but not hot. Warm lubricant will drain quickly and more completely.
nAfter the crankcase is completely drained, return the pressure washer to an upright position.
nFill with lubricant following the instructions in Adding Lubricant To The Engine earlier in this manual.
NOTE: Used lubricant should be disposed of at an approved disposal site. See your local oil retailer for more information.
PUMP LUBRICATION
The pump on this product was lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrica- tion is required.
STORING THE PRESSURE WASHER
See Figure 33.
Store the pressure washer with the gas tank empty by either draining the tank or running the pressure washer until the gas runs out. Allow 30 minutes of “cool down” time before storing the machine. Store in a dry, covered area where the weather can’t damage it.
It is important to store this product in a
