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
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 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 fuelair
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 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 meets the maximum pressure rating
of your pressure washer.
Check Chemical Injection Tube
Examine the filter on the detergent hose and clean if
clogged. The tube should fit tightly on the barbed
fitting. Examine the tube for leaks or tears. Replace
the filter or tube if either is damaged.
Check In-Line Filter
Refer to Figure 12 and service the in-line filter if it
becomes clogged, as follows:
1. Detach gun and lance 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.
4. Place the o-ring into the recess. Push the o-ring
snugly against the in-line filter screen.
5. Assemble the lance to the spray gun, as
described earlier in this manual.
