MAINTENANCE AND STORAGE

This pressure washer should be stored in such a way to protect it from freezing. *Do not store this unit outdoors or in an area where temperatures will fall below 32ºF. This can cause extensive damage to this unit. Drain as much water as possible as follows:

1.Put engine switch in "OFF" position and remove spark plug wire from spark plug.

2.Pull the trigger on the spray gun to release the pressure in the high pressure hose. Detach high pressure hose and garden hose from the unit.

3.Pull the starter handle on engine 4 to 6 times to discharge remaining water in pump.

*If unit has to be stored under freezing conditions a non- toxic R.V. anti-freeze can be used to protect from freezing.

Add anti-freeze as follows:

1.Put engine switch in "OFF" position and remove spark plug wire from spark plug.

2.Pull the trigger on the spray gun to release the pressure in the high pressure hose. Detach high pressure hose and garden hose from the unit.

3.Tip the unit on the end with the water inlet fitting pointing upward.

4.Pour approximately 1/4 cup of non-toxic R.V. anti- freeze down the plastic fitting where the water hose attaches to the pump.

5.Set unit upright and pull starter handle on engine 4 to 6 times to circulate anti-freeze in pump until anti- freeze is discharged from pump.

MAINTENANCE SCHEDULE FOR PUMP

ALWAYS REMOVE SPARK PLUG WIRE FROM SPARK PLUG BEFORE ANY

MAINTENANCE IS STARTED.

MAINTENANCE

1.WATER SCREEN:

Inspect the water screen before attaching water supply. Clean water screen if dirty. (The water screen is located in the quick connect coupler.)

2.SIPHON HOSE:

If the siphon tube is used for detergent or wax remove and place in a container of clean water. Run clean water through the unit to flush any

detergent or wax from the pressure washer.

3.NOZZLE CLOGGED:

A clogged nozzle will cause the operating pressure to be too high causing the pressure washer to surge. If this happens:

1.Put engine switch in "OFF" position and remove wire from spark plug.

2.Pull trigger on gun handle to relieve pressure, remove wand assembly from gun assembly.

3.Clear the nozzle with the nozzle cleaning tip.

4.Flush wand assembly backwards with water or compressed air.

5.If pressure is still too high, repeat steps 2-4.

4.CHECKING OIL:

The pump is shipped with the correct amount of oil in it. This pump should never need any oil added or changed unless it develops a leak. A 30 weight non- detergent oil can be used in this pump (approximately

6oz.).

If pump is leaking oil take to an Authorized Service Center.

HIGH PRESSURE HOSE: Damaged high pressure hoses can burst which can cause a potentially hazardous situation. High pressure hoses should not be kinked, crushed, twisted, or damaged in any way. Replace high pressure hose should this occur.
