Selector 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 nozzle clogged or
restricted with foreign materials, such as dirt, etc. To correct
the problem, immediately clean the nozzles following these
instructions:
WARNING The high pressure stream of water that
this equipment produces could cut through skin
and its underlying tissues, resulting in serious
injury and possible amputation.
Spray gun traps high water pressure, even when engine is
stopped and water is disconnected, which could result in
serious injury.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point spray gun in safe direction, press red button
and squeeze spray gun trigger to release high pressure, every
time you stop engine.
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction, press red
button and and squeeze spray gun trigger to release
retained high water pressure.
3. Remove selector nozzle from end of nozzle extension.
4. Use a small paper clip to free any foreign material
clogging or restricting each nozzle (A) in the selector
nozzle.

ENGINE MAINTENANCE

WARNING Unintentional sparking could cause fire or
electric shock resulting in death or
serious injury.
WHEN ADJUSTING OR MAKING REPAIRS TO YOUR PRESSURE

• Disconnect the spark plug wire from the spark plug and place
the wire where it cannot contact spark plug.
WHEN TESTING FOR ENGINE SPARK
• Use approved spark plug tester.
• DO NOT check for spark with spark plug removed.
Oil
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF, SG,
SH, SJ or higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W30 may cause increased oil
consumption. Check oil level more frequently.
NOTICE Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with
"SJ/CF ENERGY CONSERVING" or higher, is an
acceptable oil at all temperatures. Use of synthetic oil
does not alter required oil change intervals.
