Portable Pressure Washer Familiarization and Troubleshooting Guide
Part 1 - General Maintenance
This section describes the general maintenance procedures
recommended for pressure washer components that are
common across product lines.
Chemical Injection System
Before each use, inspect the chemical injection suction hose
strainer. Clean as necessary, or replace if damaged, torn or
perforated.
Examine the chemical suction hose and replace if damaged.
Rinse the chemical injection system thoroughly after each
use by siphoning several pints of clean water through the
system.
Inlet Water Supply Connector
The pressure washer may be equipped with a “Quick
Disconnect” type connector for convenient attachment of
the inlet water supply. This type of connector, depicted in
Figure 3.1, operates easily if the o-ring is periodically
lubricated with a petroleum jelly.
The water supply quick-disconnect must be correctly
installed on the supply hose and the pressure washer or its
inlet supply filter will not be effective.
Inlet Supply Filter/Strainer
Remove the quick disconnect from the hose and inspect the
inlet water strainer. It should be oriented so that the
pointed part (the screen) points away from the pump
(towards the garden hose).
A typical inlet supply connection is seen in Figure 3.2. Clean
the strainer or replace it if it is damaged, torn, or
perforated. Reassemble the connectors, using petroleum
jelly as necessary to ease the connections.
Hose, Spray Gun and Wand Systems
With the pressure washer OFF, inspect the hose connection
to the spray gun. Make sure it is tight. Test the trigger by
squeezing it and making sure it springs back to the OFF
position when released. Set the safety latch to ON and and
test the trigger, making sure the trigger cannot be squeezed.
With the pressure washer ON and the trigger latched OFF,
verify the absence of leaks from the spray gun.
With the pressure washer OFF, inspect the high pressure
hose for cuts, leaks, abrasions, bulging, kinking, or abuse.
With the pressure washer ON and the trigger latched OFF,
verify the absence of leaks from the hose.
DANGER:
Water spraying from a leaking hose can
inject material into the skin or cause serious injury.
Never attempt to repair high pressure hoses. Replace
the hose with a high quality hose that meets the
minimum pressure rating recommended by the
manufacturer.
An o-ring maintenance kit for each model is available to
refurbish all connection seals.
