DeVillbiss Air Power Company W1218, MGP-1218 Maintenance And Storage, Water Screen, Siphon Hose

MAINTENANCE AND STORAGE

ALWAYS DISCONNECT THE PLUG FROM THE ELECTRICAL SUPPLY BEFORE

ANY MAINTENANCE IS STARTED.

MAINTENANCE

1.WATER SCREEN:

Inspect the water screen before attaching water supply. Clean water screen if dirty.

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.Unplug power supply, pull trigger on gun handle to relieve pressure, remove wand assembly from gun assembly.

2.Clean the nozzle with the nozzle cleaning kit.

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

4.If pressure is still too high, repeat steps 1-3.

4.LUBRICATION:

No lubrication is required for this pump.

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.

STORAGE

This pressure washer should be stored in such a way to protect it from freezing. Do not store this unit out- doors 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.Stop the pressure washer, detach the water hose, and pull the trigger on the spray handle to re- lease the pressure in the inlet hose.

2.Restart the unit, pull the trigger, and run until water no longer sprays out of the nozzle. (Approximately 30 seconds)

3.Stop unit. Detach high pressure hose from unit. Leave hose attached to wand to protect it against accidental dropping. Pull trigger to drain water from wand and hose, and place assembly in storage.

*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.Be sure the unit is turned off, the water supply hose is disconnected, and pressure has been relieved from the gun. Do not disconnect the high pressure hose or gun.

2.Tip the unit on end with the water inlet fitting pointing upward, and start the motor.

3.Pour approx. 1/4 cup of non-toxic R.V. anti-freeze down the plastic fitting where the water hose attaches while the motor is running (See Figure 3 below). Let unit run for a few seconds.

4.Turn the unit off and pull the trigger on the gun to relieve any pressure from the hose and gun.

5.After removing the high pressure hose, restart the unit to displace any water remaining in the pump.
