MAINTENANCE

NOZZLE MAINTENANCE

See Figure 21.

Excessive pump pr essure (a pulsing sensation felt while squeezing the trigger) may be the r esult of a clogged or dirty nozzle.

nTurnoff the pressure washer and shut off the water supply. Pull trigger to release water pressure.

nRemovethe nozzle from the spray wand.

NOTE: Never point the spray wand at your face.

nUsinga straightened paper clip or nozzle cleaning tool (not provided), free any foreign materials clogging or restricting the nozzle.

nUsinga garden hose, flush debris out of nozzle by back flushing (running the water through the nozzle backwards or from the outside to the inside).

nReconnecthe nozzle to the spray wand.

nTurnon the water supply and start the engine.

CLEANING THE AIR FILTER

See Figure 22.

A dirty air filter will cause starting dif ficulty, loss o f performance, and shorten the life span ofthe engine. Check the air filter monthly. For best performance, replace the air filter at least once a year.

nUnscrew air filter knob, then remove the air filter cover.

nLift the edge of the air filter carefully and pull it out.

nWash the air filter with warm, soapy water.

nRinse and squeeze to dry.

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 using a plug cleaner or wire brush. Replace the plug if worn. (Recommended spark pl ug: BPR6H S (NGK) or equivalent.)

nCheck electrode gap. The gap should be .03 in. (0.7- 0.8 mm). Adjust the gap, if necessary, by carefully bending the ground electrode.

nReinstall spark plug. Tighten securely.

CHANGING ENGINE LUBRICANT

See Figure 24.

nShut off the engine.

nClean the area around the lubricant fill cap/dipstick,then remove the lubricant fill cap/dipstick.

nTilt the pressure washer on its side as shown. Drain lu- bricant 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.

n Fill with lubricant following the instructions in Adding Lubricant To The Engine earlier in this manual.

NOTE: Consult hazardous waste management guidelines in your area for the proper way to dispose of used lubricant.

PUMP LUBRICATION

The pump on this product was lubricated with a suf ficient 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 25.

Store the pressure washer with the gas tank empty by either draining the tank or running the pr essure washer until the gas runs out. Allow 30 minutes of “cool down” time before storing the machine. Never place the unit in any position other than upright on its wheels.

Store in a dry, covered area where the weather can’t damage it.

It is important to store this product ina frost-free area. Always empty water fr om all hoses, the pump, and the deter gent bucket before storing.

NOTE: Use of a fuel stabilizer and pump saver will give you better performance and increase the life of the machine.

Discharge Fuel:

Drain the fuel tank completely . Stored gas can go stale in 30 days.
