POWER CORD STORAGE
See Figure 17.
When it is not in use, the power cord may be wrapped around
the two brackets on the back of the unit.
To secure the power cord in place, flip the bracket to the
up position.
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could 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 motor, wait for all moving parts to stop, disconnect
unit from power supply, and pull trigger to release water
pressure. 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 could result in serious personal
injury.
OPERATION
MOVING THE PRESSURE WASHER
 Turn the pressure washer off. Point nozzle in a safe direc-
tion and pull trigger to release water pressure.
 Raise the handle up until the buttons click into the holes
on the handle.
 Tilt the machine toward you until it balances on the wheels
then roll the machine to the desired position.
 DO NOT attempt to move the unit by pulling on any of
the hoses.

MAINTENANCE

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.

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 18.
Excessive pump pressure (a pulsing sensation felt while
squeezing the trigger) may be the result of a clogged or
dirty nozzle.
 Unplug the pressure washer.
 Turn off the pressure washer and shut off the water sup-
ply. Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
 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.
