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 could result in serious personal
injury.
PUMP LUBRICATION
The pump on this unit is lubricated with a sufficient amount
of high grade lubricant for the life of the unit under normal
operating conditions. Therefore, no further lubrication is
required.
POWER SUPPLY CORD REPLACEMENT
If replacement of the power supply cord is necessary, this
must be done by an authorized service center in order to
avoid a safety hazard.
NOZZLE MAINTENANCE
See Figure 19.
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, disconnect from power
supply, 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 mo-
tor, disconnecting from power supply, 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.
MAINTENANCE
 Using a straightened paper clip or nozzle cleaning tool
(not provided), free any foreign materials clogging or
restricting the nozzle.
 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 motor.
PUMP MAINTENANCE
Routinely make a visual inspection of the pump. If you notice
any leaking of lubricant around the pump oil 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.
STORING THE PRESSURE WASHER
See Figure 20.
NOTE: Regular use of pump protector will give you
better performance of the unit and increase the life of
the pump. See the Replacement Parts List for available
sizes and part numbers of these items and call customer

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
bucket before storing.

before storing.
 Make sure the on/off switch is in the OFF position.
 Disconnect the water connection.
 Tilt the unit as shown to drain out any water remaining in
the pump.
NOTICE:
The use of a pump protector is required after each use
and before storing to prevent cold weather and seal
damage during storage. Failure to use pump protector
will void your warranty.
 Coil the hose and place in the hook-and-loop strap on the
unit's handle. Do not allow the hose to become kinked.
 Store the unit and accessories in an area that does not
reach freezing temperatures. Do not store near furnace or
