GENERAL RECOMMENDATIONS
The pressure washers 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 pressure washer as
instructed in this manual including proper storage as
detailed in “Storage” on page 13.
Some adjustments will need to be made periodically to
properly maintain your pressure washer.
All service and adjustments should be made at least
once each season. Follow the requirements in the
“Maintenance Schedule” chart above.
NOTE: Once a year you should clean or replace the
spark plug and replace the air filter. 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 in-line filter for damage.
• Check high pressure hose for leaks.
• Check chemical filters for damage.
• Check spray gun and nozzle extension assembly
for leaks.
• Purge pump of air and contaminants.
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.
A CAUTION! Never repair a high pressure hose.
Replace with hose that exceeds the maximum
pressure rating of your pressure washer.
Check Spray Gun and Nozzle Extension
Examine hose connection to spray 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 spray 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
1. Detach spray gun and nozzle extension from high
pressure hose. Detach nozzle extension from spray
gun and remove o-ring and screen from nozzle
extension. Flush the screen, spray 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.
