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 an 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 supplied 2mm
(5/64) allen wrench, remove orifice from end of nozzle
extension (Figure 14).
