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, 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.
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:
 Check that all bolts, nuts, etc., are securely tightened.
 Make sure the air filter is clean.
 Check both the engine lubricant level and the fuel tank
level; refill as needed.
 Inspect the work area for hazards.
 If there is excessive noise or vibration, stop the unit
immediately.

MAINTENANCE

NOZZLE MAINTENANCE

Excessive pump pressure (a pulsing sensation felt while pull-
ing the trigger) may be the result of a clogged or dirty nozzle.
 Turn off the pressure washer and shut off the water
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
nozzle, blow out or remove debris with a fine needle.
 Using 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).
 Reconnect the nozzle to the spray wand.
 Turn on the water supply and start 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 dam-
age the pressure washer and void your product warranty.
LONG-TERM STORAGE OF THE PRESSURE
WASHER
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. Never store the unit in any position other
than upright on its wheels.
It is important to store this product in a frost-free area. Always
empty water from all hoses, the pump, and the detergent
bucket before storing.
Discharge Fuel:
Drain the fuel tank completely by running the pressure washer
until the gas runs out. Stored gas can go stale in 30 days.
NOTE: Make sure the water supply is connected and turned
on when allowing the pressure washer engine to run.
Engine Lubricant:
Drain the lubricant and replace with fresh, clean lubricant
as described in Adding/Checking Engine Lubricant in the
Operation section of this manual.
