Before Each Use
1.Check engine oil level.
2.Clean debris.
3.Check water inlet screen for damage.
4.Check high pressure hose for leaks.
5.Check detergent siphoning tube and tank for damage.
6.Check spray gun and nozzle extension assembly for leaks.
7.Rinse out garden hose to flush out debris.
Pressure Washer Maintenance
Clean Debris
Daily or before use, clean accumulated debris from cleaning system. Keep linkage, spring and controls clean. Keep area around and behind muffler free from any combustible debris. Inspect cooling air slots and openings on the pressure washer. These openings must be kept clean and unobstructed.
Pressure washer parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris.
• Use a damp cloth to wipe exterior surfaces clean.
NOTICE
Improper treatment of pressure washer can damage it and shorten its life.
•DO NOT insert any objects through cooling slots.
•Use a soft bristle brush to loosen caked on dirt, oil, etc.
•Use a vacuum cleaner to pick up loose dirt and debris.
Check and Clean Inlet Screen
Examine the screen on the pump’s water inlet. Clean it if the screen is clogged or replace it 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 the hose immediately.
WARNING
The high pressure stream of water that this equipment produces can cut through skin and its underlying tissues, leading to serious injury and possible amputation.
•NEVER repair high pressure hose. Replace it.
•Replacement hose rating MUST exceed maximum pressure rating of unit.
Check Detergent Siphoning Tube
Examine the detergent tank and detergent siphoning tube and clean if clogged. The tube should fit tightly on the barbed fitting of the pump and detergent
Check Gun and Nozzle Extension
Examine the hose connection to the spray gun and make sure it is secure. Test the trigger by pressing it and making sure it “springs back” into place when you release it. Put the trigger lock in the ON position and test the trigger. You should not be able to press the trigger.
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 engine and turn off water supply.
2.ALWAYS point spray gun in a safe direction and squeeze spray gun trigger to release retained high water pressure.
WARNING
The high pressure stream of water that this equipment produces can cut through skin and its underlying tissues, leading to serious injury and possible amputation.
Spray gun traps high water pressure, even when engine is stopped and water is disconnected, which can cause injury.
•Keep high pressure hose connected to pump and spray gun while system is pressurized.
•ALWAYS point spray gun in safe direction and squeeze spray gun trigger, to release high pressure, every time you stop engine. Engage trigger lock when not in use.
3.Remove nozzle from end of nozzle extension.
4.Use a small paper clip to free any foreign material clogging or restricting nozzle (A).

5.Remove nozzle extension from spray gun.
