GENERAL MAINTENANCE
RECOMMENDATIONS
The warranty of the high pressure washer does not
cover items that have been subjected to operator
abuse or negligence. To receive full value from the
warranty, operator must maintain high pressure
washer as instructed in this manual.
Some adjustments will need to be made periodi-
cally to properly maintain your high pressure
washer.
All adjustments in the Service and Adjustments
section of this manual should be made at least
once each season.
Once a year you should clean or replace the spark
plug and clean or replace the air filter and check the
gun and wand assembly for wear. A new spark plug
and clean air filter assure proper fuel-air mixture
and help your engine run better and last longer.
BEFORE EACH USE
Check engine oil level.
Check water inlet screen for damage.
Check high pressure hose for leaks.
Check gun and wand assembly for leaks.
PRESSURE WASHER
MAINTENANCE
Check and Clean Inlet Screen
Examine screen on the water inlet. Clean if the
screen is clogged or replace if screen is damaged.
Check High Pressure Hose
High pressure hose can develop leaks from wear,
kinking, or abuse. Inspect hose each time before
using it. Check for cuts, leaks, abrasions or bulging of
cover, damage or movement of couplings. If any of
these conditions exist, replace hose immediately.
DANGER: Water spraying from a leak is
capable of injecting material into skin.
Inspect hose each time before using it.
Never repair a high pressure hose.
Replace it with another hose that meets
the maximum pressure rating of your
pressure washer.
Check Gun and Wand
Examine hose connection to gun and make sure it is
secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Put safety
latch in ON position and test trigger. You should not be
able to press trigger.
Purge Pump of Air and
Contaminants
To remove the air from the pump, follow these
steps:
Set up the pressure washer as described in the
ASSEMBLY section and connect the water supply.
Remove the wand extension from the gun.
Pull the trigger on the gun and hold.
To remove the contaminants from the pump,
follow these steps:
Set up the pressure washer as described in the
ASSEMBLY section, and connect the water supply.
Remove the nozzle attachment from the gun.
Start the engine according to instructions in OPER-
ATION section.
Squeeze the trigger on the gun and hold.
When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
attachment.
Nozzle Maintenance
If the adjustable nozzle becomes restricted or
clogged with foreign materials, such as dirt, excessive
pump pressure may develop. If this nozzle becomes
partially clogged, it can cause a pulsing sensation
during use. This generally is not a pump related
problem, but rather a clogged or partially restricted
adjustable nozzle.
If the adjustable nozzle becomes clogged or partially
restricted, immediately clean the nozzle with the kit
included with your pressure washer by following
these instructions:
Shut off the engine and turn off the water supply.
Separate the wand extension from the gun.
Adjust the wand extension to the stream position.
Remove nozzle from the end of the wand extension
(Figure 13) using a 2mm or 5/64 allen wrench (like
the one included in the kit).
