USING PUMP PROTECTOR
See Figure 14.
Regular use of a commercially available pump protector
prolongs the life of the pressure washer by removing hard
water mineral deposits, lubricating pump seals and pistons,
and preventing freeze damage. Pump protector should
be added to the unit after every use and before storage.
Pump protector can be purchased at the retailer where you
purchased your pressure washer, or by calling customer
service.
The instructions that follow are typical for adding pump
protector but you should always verify the specific
instructions provided by the manufacturer of the pump
protector used.
 Turn off the pressure washer motor, disconnect the power
supply, and shut off the water supply. Pull trigger to
release water pressure.
 Disconnect garden hose and high pressure hose.
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.
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:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
NOTICE:
Periodically inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts, caps,

are replaced. Please contact customer service or an
authorized service center for assistance.
OPERATION

MAINTENANCE

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.
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 15.
Excessive pump pressure (a pulsing sensation felt while
squeezing the trigger) may be the result of a clogged or
dirty nozzle.
