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

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.
OPERATION
STORING PRESSURE WASHER AFTER USE
See Figure 21.
You must pull the trigger to release water pressure before
attempting to disconnect the nozzle or high pressure hose
for storage. Shutting off engine will not relieve pressure in
the system.
To change the position of the handle for easier storage, lower
the lock levers on each side of the handle. Move the handle
to the desired storage position, then return the lock levers
to the locked position.
NOTE: The teeth of the handle cogs must be intertwined to
allow the handle to lock.
For long term storage, see Storing the Pressure Washer
in the Maintenance section of this manual.

MAINTENANCE

Only the parts shown on the parts list are intended to be

Before running the engine, perform the following pre-
operation steps:
 Check that all bolts, nuts, etc., are securely tightened.

level; refill as needed.
 Inspect the work area for hazards.
 If there is excessive noise or vibration, stop the unit

dirty nozzle.

supply. Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
 To free any foreign materials clogging or restricting the

flushing (running the water through the nozzle backwards
or from the outside to the inside).
 Reconnect the nozzle to the spray wand.
