place and lock when released.

Nozzle Maintenance

A pulsing sensation felt when squeezing spray
gun trigger may be caused by excessive
pump pressure. Typical causes of excessive
pump pressure are nozzle clog or restriction.
Immediately clean nozzle as follows:
Fluid Injection. This machine produces high-
pressure fluid streams that can pierce skin.
Fluid injection will result in death or serious
injury.
1. Turn engine and water supply OFF.
NOTE: Keep high-pressure hose con-
nected to pump and spray gun while sys-
tem is pressurized.
2. Relieve spray gun water pressure.
3. Remove nozzle from lance.

Engine Maintenance

Engine Oil Recommendations

(000106)
Only high-quality detergent oils classified for
service SF, SG, SH, SJ or higher are recom-
mended. DO NOT use special additives.
Climate determines proper engine oil viscos-
ity. See chart to select correct viscosity.
* Below 50°F (10°C) use of SAE 30 will result
in hard start.
000109
** Above 80°F (27°C) use of 10W30 may
cause increased oil consumption. Inspect
oil level more frequently.
