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 orifice
clogged or restricted with foreign materials, such as dirt,
etc.To correct the problem, immediately clean the orifice
using the tools included with your pressure washer and
follow these instructions:
1. Shut off engine and turn off water supply.
2. Detach nozzle extension from spray gun.Twist nozzle
clockwise to stream position. Using 2mm (5/64) allen
wrench, remove orifice from end of nozzle extension
(Figure 13).

O–Ring Maintenance
Through the normal operation of your pressure washer,
o–rings are used to keep the connections of the hoses and
spray gun tight and leak–free.These o-rings may become
worn or damaged.
An O–Ring Maintenance Kit is provided with your pressure
washer which includes replacement o-rings, rubber washer
and water inlet filter. Refer to the instruction sheet
provided in the kit to service your unit's o-rings. Note that
you will not use all of the parts in the kit.
To remove a worn or damaged o–ring; use a small flathead
screwdriver to get underneath the o-ring and pry it off.
