MAINTENANCE
WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO HOT SURFACES, WATER PRESSURE, MOVING PARTS, OR FIRE RESULTING IN DEATH. BEFORE PERFORMING ANY MAINTENANCE OR REPAIR, DISCONNECT SPARK PLUG WIRE, LET ENGINE COOL AND RELEASE ALL WATER PRES- SURE. THE ENGINE CONTAINS FLAMMABLE FUEL. DO NOT SMOKE OR WORK NEAR OPEN FLAMES WHILE PERFORMING MAINTENANCE.
To ensure efficient operation and longer life of your pressure washer, a routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to a unit in a normal working environment. If necessary, the schedule should be modified to suit the conditions under which your pressure washer is used. The modifications will depend upon the hours of operation and the working environment. If the pressure washer is in an extremely dirty and/or hostile environment, it will require a greater frequency of all maintenance checks.

5.Replace oil fill plug and tighten securely.
HOW TO CLEAN THE NOZZLE
If the nozzle becomes clogged with foreign material such as dirt, excessive pump pressure may develop and the spray pattern will change. If a nozzle be- comes partially clogged or restricted, the pump pressure will pulsate. If this happens, clean the nozzle immediately using the nozzle cleaning kit supplied with your pressure washer. The procedure is as follows:
1.Shut off pressure washer and turn off water supply.
2.Pull trigger on spray gun to relieve any water pressure.
3.Disconnect

7.Direct water supply into nozzle end for 30 seconds to back flush loosened particles.
8.Take this opportunity to inspect wand for obstruc- tions. Back flush wand if obstructions are seen.
9.Reassemble nozzle to wand. Tighten securely to prevent leaks.
10.Reconnect
11.Start pressure washer and test spray pattern. See How To Use Wand in the Operation Section.
