PRESSURE WASHER

MAINTENANCE

Check and Clean Inlet Screen

Examine garden hose inlet screen. Clean if it is clogged or replace if it is torn.

Check High Pressure Hose

High pressure hoses can develop leaks from wear, kinking, or abuse. Inspect hose before each use. Check for cuts, leaks, abrasions, bulging of cover, or damage or movement of couplings. If any of these conditions exist, replace hose immediately.

2.Place in-linefilter screen into threaded end of nozzle extension. Direction does not matter. Push screen in with eraser end of pencil until it rests flat at bottom of opening. Take care to not bend screen.

3.Place o-ring into recess. Push o-ring snugly against in-line filter screen.

4.Assemble nozzle extension to spray gun, as described earlier in manual.

Purge Pump of Air and Contaminants

To remove air from the pump, follow these steps:

1.Set up pressure washer as described in "Assembling Your Pressure Washer" section and connect water supply.

2.Pull trigger on gun and hold until a steady stream of water appears.

To remove contaminants from the pump, follow these steps:

1.Set up pressure washer as described in "Assembling Your Pressure Washer" section, and connect water supply.

2.Remove nozzle extension from gun.

3.Start engine according to instructions in "How To Use Your Pressure Washer s section.

4.Pull trigger on gun and hold.

5.When water supply is steady and constant, engage safety latch and refasten nozzle extension.

Check Gun and Nozzle Extension

Examine hose connection to spray gun and make sure it is secure. Test trigger by pressing it and making sure it springs back into place when you release it. Put safety latch in UP position and test trigger. You should not be able to press trigger. Replace spray gun immediately if it fails any of these tests.

1.Detach spray gun from high pressure hose. Detach nozzle extension from spray gun and remove o-ring and screen from nozzle extension.

Flush screen, spray gun, and nozzle extension with clean water to clear debris.

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 spray tip clogged or restricted with foreign materials, such as dirt, etc. To correct the problem, immediately clean the spray tip following these instructions:

1.Shut off engine and turn off water supply.

2.Remove spray tip from end of nozzle extension.

3.Remove in-line filter from other end of nozzle extension.

4.Use a small paper clip to free any foreign material clogging or restricting spray tip.

Use wire here to remove debris.
