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 the full value from the
warranty, the operator must maintain the high pres-
sure washer as instructed in this manual.
Some adjustments will need to be made periodically
to properly maintain your high pressure washer.
All adjustments in the Service and Adjustments sec-
tion 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 detergent siphoning tube and filter for
damage.
Check gun and wand assembly for leaks.
PRESSURE WASHER
MAINTENANCE
Check and Clean Inlet Screen
Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the 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 the 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 Detergent Siphoning Tube
Examine the filter on the detergent hose and clean if
clogged. The tube should fit tightly on the barbed fit-
ting. Examine the tube for leaks or tears. Replace the
filter or tube if either is damaged.
Check Gun and Wand
Examine the hose connection to the gun and make
sure it is secure. Test the trigger by pressing it and
making sure it springs back into place when you
release it. Put the safety latch in the ON position and
test the trigger. You should not be able to press the
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
PREPARING THE PRESSURE WASHER FOR
FIRST USE 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
HOW TO USE YOUR PRESSURE WASHER sec-
tion, 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.
Cleaning Detergent Siphoning
Tube
If you have used the detergent siphoning tube you
must flush it with clean water before stopping the
engine.
Place the detergent siphoning tube in a bucket full
of clean water.
Flush for 1-2 minutes.
Shut off the engine.
Important:
Simply shutting OFF engine will not release
pressure in the system. When the engine has shut down,
squeeze the trigger on the gun to relieve the pressure
in the hose.
