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 could result in serious personal
injury.
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 im-
mediately.
NOZZLE MAINTENANCE
See Figure 18.
Excessive pump pressure (a pulsing sensation felt while
squeezing 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.
WARNING:
NEVER remove nozzles without first turning off the engine,
relieving the water pressure in the trigger handle, and
locking the lock out on the trigger handle. NEVER point
the nozzle at your face or at others. The quick-connect
feature contains small springs that could eject the nozzle
with some force. Failure to follow these instructions could
result in an eye injury or other serious personal injury.
 To free any foreign materials clogging or restricting the
nozzle, blow out or remove debris with a straightened
paper clip or 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 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.
MAINTENANCE
PUMP MAINTENANCE
Routinely make a visual inspection of the pump. If you no-
tice any leaking of lubricant around the pump seals, take
the pressure washer to a qualified 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.
STORING THE PRESSURE WASHER
See Figure 19.
NOTE: Regular use of fuel stabilizer and pump protector
will give you better performance of the unit and increase
the life of the pump.
WARNING:
While storing, keep at least 3 feet of clearance on all sides
of this product, including overhead. Allow a minimum
of 30 minutes of "cool down" time before storage. Heat
created by muffler and exhaust gases could be hot
enough to ignite combustible objects.
Store in a dry, covered area where the weather can't damage it.
It is important to store this product in a frost-free area. Al-
ways empty water from all hoses, the pump, and the soap
tank before storing.
 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.
 Make sure the on/off switch is in the OFF position and
the fuel valve is in the CLOSED position.
 Disconnect both the high pressure hose and the garden
hose from the pump.
 Empty the pump by pulling on the starter grip and rope
about 6 times. This should remove most of the liquid from
the pump.
NOTICE:
If the location where your pressure washer is stored will
fall below 32°F, the use of a pump protector is required
before storing to prevent freeze damage. Freeze damage
will void your warranty.
 Drain the lubricant and replace with fresh, clean lubricant
as described in the engine manual.
 Disconnect spark plug wire and remove the spark plug.
Pour about a teaspoon of clean, air-cooled, four-cycle
lubricant through the spark plug hole into the combustion
chamber.
