MAINTENANCE
• SAVE ALL INSTRUCTIONS
CONNECTIONS
Connections on pressure washer hoses, gun
and spray wand should be cleaned regularly
and lubricated with silicon grease to prevent
leakage and damage to the o-rings.
NOZZLE
Clogging of the nozzle causes the pump
pressure to be too high and cleaning is
immediately required.
WARNING
A nozzle cleaner must
only be used when the spray nozzle is
disconnected from the gun or personal
injury could result.
1. Remove the nozzle from the wand.
2. Clear the nozzle with the nozzle cleaner
pin provided with the pressure washer.
3. Flush the nozzle backwards with water.
4. Re-install the nozzle into the wand.
Restart the pressure washer and depress the
trigger on the spray gun. If the nozzle is still
plugged or partially plugged, repeat above
items 1-4.
If the previous procedure does not clear the
nozzle, replace with a new nozzle.
WATER SCREEN
The pressure washer is equipped with a water
inlet screen to protect the pump. If the screen
is not kept clean, it will restrict the flow of
water to the pressure washer and may cause
damage to the pump. Do not damage the
screen while removing or cleaning screen.
Any foreign particles entering the pump may
damage the pump. Do not operate pressure
washer without the screen in place.
Remove the screen and back flush to remove
impurities from screen. Replace immediately.
ENGINE MAINTENANCE
During the winter months, rare atmospheric
conditions may develop which will cause an
icing condition in the carburetor. If this
develops, the engine may run rough, lose
power, and may stall.
NOTE: Refer to the engine manufacturer’s
manual for service and maintenance of
the engine.
