PRESSURE
WASHER
MAINTENANCE
Check and Clean Inlet Screen
Examine garden hose inlet screen. Clean if it is
clogged or replace if it is torn.
Check High Pressure
Hose
High pressure hoses can develop leaks from wear,
kinking, or abuse. Inspect hose before each use.
Check for cuts, leaks, abrasions, bulging of cover, or
damage or movement of couplings. If any of these
conditions exist, replace hose immediately.
_
AUTION!
NEVER repair a high pressure
hose. Replace with hose that exceeds the
maximum pressure rating of your pressure
washer.
Check Gun and Nozzle Extension
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. Engage
safety latch and test trigger. You should not be able to
press trigger. Replace gun immediately if it fails any of
these tests.
Check
In-Line Filter
Refer to the illustration and service the in-line filter if it
becomes clogged, as follows:
In-line Filter
Nozzle extension
O-ring
1. Detach nozzle extension from gun and remove
o-ring and screen from nozzle extension. Flush the
screen, gun, and nozzle extension 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 nozzle extension. 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 nozzle extension to the spray gun,
as described earlier in this manual.
Purge Pump of Air and Contaminants
To remove air from the pump, follow these steps:
•
Set up the pressure washer as described in the
"Assembling Your Pressure Washer" section and
connect the water supply.
•
Pull the trigger on the gun and hold until a steady
stream of water appears.
To remove contaminants from the pump, follow these
steps:
•
Set up the pressure washer as described in the
"Assembling Your Pressure Washer" section, and
connect the water supply.
•
Remove the nozzle extension from the gun.
•
Start the engine according to instructions in "How
To Use Your Pressure Washer" section.
•
Pull the trigger on the gun and hold.
•
When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
extension.
Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure.
The principal cause of excessive pump pressure is a
nozzle clogged or restricted with foreign materials,
such as dirt, etc. To correct the problem, immediately
clean the nozzle using the tools included with your
pressure washer and follow these instructions:
1. Shut off the engine and turn off the water supply.
2. Remove the nozzle from the end of the nozzle
extension. Separate the nozzle extension from the
spray gun. Twist the nozzle clockwise to the
stream position. Using the supplied 2mm (5/64)
allen wrench, remove the nozzle from the end of
the nozzle extension.
\
3. Remove the in-line filter from the other end of the
nozzle extension.
4. Use the wire included in the kit (or a small paper
clip) to free any foreign material clogging or
restricting the nozzle.
