MAINTENANCE
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
Excessive pump pressure (a pulsing sensation felt while pull- ing the trigger) may be the result of a clogged or dirty nozzle.
nTurn off 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.
nTo free any foreign materials clogging or restricting the nozzle, blow out or remove debris with a fine needle.
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.
CLEANING/REPLACING THE AIR FILTER
See Figure 19.
A dirty air filter will cause starting difficulty, loss of perfor- mance, 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.
The filter cover pivots up and lifts off.
nUsing a damp cloth, wipe the air filter cover and inner surface. Take care not to allow dust to enter the carbure- tor.
nRemove the air filter.
nRinse filter with clean water.
nGently squeeze filter until excess water is removed.
nApply a light coat of engine lubricant to the filter, then squeeze it out.
nReinstall the foam filter.
nReinstall the filter cover.
NOTE: Make sure the filter is seated properly inside the compartment. Installing the filter incorrectly will allow dirt to enter the engine, causing rapid engine wear.
CHANGING ENGINE LUBRICANT
See Figure 20.
nShut off the engine.
nClean the area around the oil fill cap/dipstick, then remove the oil fill cap/dipstick.
To drain lubricant from the oil drain plug:
nDisconnect the spark plug wire from the engine.
nTo drain the lubricant, remove the drain plug from the bottom of the engine. Drain lubricant into approved con- tainer.
NOTE: Remove the dipstick to allow lubricant to drain easier and more quickly.
nFill with lubricant following the instructions in Adding/ Checking Engine Lubricant earlier in this manual.
nBefore using the pressure washer, check to ensure that no lubricant is leaking from the engine.
NOTE: Used lubricant should be disposed of at an ap- proved disposal site. See your local oil retailer for more information.
CHECKING SPARK PLUG
See Figure 21.
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 or reuse is questionable. (Recommended spark plug: Champion RC12YC).
nCheck electrode gap. The gap should be 0.7 - 0.8 mm in. Adjust the gap, if necessary, by carefully bending the ground electrode.
nCheck the condition of the spark plug gasket.
nReinstall spark plug. Start the spark plug in its threads by hand and
nTighten with wrench to compress washer. If spark plug is new, use 1/2 turn to compress washer appropriate amount. If reusing old spark plug, use 1/8 to 1/4 turn for proper washer compression.
NOTE: An improperly tightened spark plug will become very hot and could damage the engine.
PUMP MAINTENANCE
Routinely make a visual inspection of the pump. If you notice any leaking of lubricant around the pump seals, take the pressure washer to an authorized service center for repair.
There are no user serviceable parts to the pressure washer pump. Any attempt to service or alter the pump may damage the pressure washer and void your product warranty.
STORING THE PRESSURE WASHER
See Figure 22.
Store the pressure washer with the gas tank empty by either draining the tank or running the pressure washer until the gas runs out.
NOTE: If running pressure washer until gas runs out, make sure machine is connected to water and water is ON.
Allow 30 minutes of “cool down” time before storing the machine. Store in a dry, covered area where the weather can’t damage it.
