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 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 the engine owners manual should be
made at least once each season.
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 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
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 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.
Check In-Line Filter
Refer to Figure 15 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.
