GENERAL MAINTENANCE
RECOMMENDATIONS
The pressure washer warranty does not cover items
that have been subjected to operator abuse or
negligence. To receive full value from the warranty, the
operator must maintain the 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 Maintenance 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
spray gun and nozzle extension 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 chemical injection tube and filter for damage.
• Check spray gun and nozzle extension assembly for
leaks.
• Rinse out garden hose to flush out debris.

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 exceeds the maximum pressure
rating of your pressure washer.
Check Gun and Nozzle Extension
Examine the hose connection to the spray 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.
Check In-Line Filter
Refer to Figure 13 and service the in-line filter if it
becomes clogged, as follows:
