PRESSURE WASHER MAINTENANCE

Check and Clean Inlet Screen

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

Check High Pressure Hose

High pressure hose can develop leaks from wear, kinking, or abuse. Inspect hose each time before tJsing it. Check for cuts, leaks, abrasions, bulging of cover, or damage or movement of coupl!ngs. If any of these conditions exist, replace hose immediately.

Check Chemical Reservoirs

Tank covers should snap cleanly onto tank. Ensure chemical labels correctly identify tank contents. Ensure that the System Rinse tank is filled with clean water. Ensure that Dial-A-Cleaner TM selector knob

rotates freely between each position. Examine the tanks and replace if the filter is clogged

2.If the screen is damaged, the o-ring kit contains a replacement in-line filter screen and an o-ring. If undamaged, reuse screen.

To remove the contaminants from the pump, follow these steps:

•Set up the cleaning system as described in the ASSEMBLY section, and connect the water supply.

•Remove the nozzle attachment from the gun.

•Start the engine according to instructionsin OPERATION section.

Pull the trigger on the gun and hold.

When the water supply is steady and constant, engage the safety latch and refasten the nozzle attachment.

Check Gun and Wand

In-Line Filter

Nozzle Maintenance

If the nozzle becomes restricted or clogged with foreign materials, such as dirt, excessive pump pressure may develop. A partially clogged nozzle can cause a pulsing condition during use. This generally is not a pump related problem, but rather a clogged or partially restricted nozzle.

If the nozzle becomes clogged or partially restricted, immediately clean the nozzle with the kit included with your cleaning system by followingthese instructions:

Shut off the engine and tum off the water supply.

•Separate the wand from the gun.

•Rotate to stream setting.

•Remove nozzle from the end of the wand using a 2mm or 5/64 allen wrench.
