CHECK SPRAY GUN
Examine the hose connection to the spray gun and make sure it is
secure. Test the trigger by pressing the trigger, it "springs back"
into place when you release it. Replace the spray gun immediately
if it fails to "spring back".
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 following these instructions:
1. Shut off the engine and turn off the water supply.
2. ALWAYS point the spray gun in a safe direction, squeeze the
spray gun trigger to release retained high water pressure.
The high pressure stream of water that this equipment
produces can cut through skin and its underlying
tissues, leading to serious injury, possible amputation
or death. Spray gun traps high water pressure, even
when engine is stopped and water is disconnected,
which can cause injury.
• Keep the high pressure hose connected to the pump and spray gun
while the system is pressurized.
• ALWAYS point the spray gun in a safe direction, and squeeze the
spray gun trigger to release high pressure every time you stop the
engine. Engage the trigger lock when not in use.
3. Remove the nozzle from the end of nozzle extension.
4. Use a small paper clip to free any foreign material clogging or
restricting the nozzle (Figure 27).
5. Remove the lance from the spray gun.
6. Using a garden hose, remove additional debris by back
flushing water through the lance (Figure 28) for 30 to 60
seconds.
7. Reinstall the nozzle into the lance.
8. Reconnect the lance to the spray gun.
9. Make sure the garden hose is connected to the pump water
inlet. Check that the high pressure hose is connected to the
spray gun and pump. Turn on the water.

10. Start the engine following the instructions How to Start Your
Power Washer.
11. Test the power washer by operating it with each quick connect
nozzle.
PUMP OIL MAINTENANCE
Change pump oil every 50 hours of operation.
1. Clean area around oil drain plug (A).
2. Remove oil drain plug. Drain oil completely.
3. Install oil drain plug. Do not over tighten.
4. Clean Area around oil dipstick (B).
5. Fill pump with SAE 30 non-detergent oil to "Full" mark on
dipstick.
6. Install oil dipstick until finger tight.
7. Clean up any spilled oil.
