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 periodically
to properly maintain your high pressure washer.
 All adjustments in the Service and Adjustments
section of the engine owners 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.

 Check water inlet screen for damage.
 Check high pressure hose for leaks.

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 Detergent Hose
Examine the filter on the detergent hose and clean if
clogged. Hose should fit tightly on barbed fitting.
Examine hose for leaks or tears. Replace the filter or
hose if either is damaged.
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.
Check In-Line Filter
Refer to Figure 14 and service the in-line filter if it
becomes clogged, as follows:
1. Detach gun from high pressure hose. Detach lance
from gun and remove o-ring and screen from lance.
Flush the screen, gun, and lance with clean water
to clear debris.
2. If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.
3. Place the in-line filter screen into the threaded end
of the lance. Direction does not matter. Push the
screen in with the eraser end of a pencil until it rests
flat at the bottom of the opening. Take care to not
bend the screen.
