NOZZLE CLEANING
If the nozzle becomes clogged with
foreign materials, such as dirt,
excessive pressure may develop. If
the nozzle becomes partially clogged

turn off the water supply.
2. Disconnect spark plug wire.
3. Pull trigger on gun handle to

back and forth until obstruction
is removed.
7. Direct water supply into nozzle
end to backflush loosened
particles for 30 seconds.
8. Reconnect spark plug wire.

Cleaning Debris
Engine parts should be kept clean to
reduce the risk of overheating and
ignition of accumulated debris.
NOTE: Do not use water to clean
engine parts. Water could
contaminate fuel system. Use a brush
or dry cloth.
Combustion Deposits
Every 100-300 hours an Authorized
Warranty Service Center should
remove combustion deposits from the
cylinder, cylinder head, top of piston,
and around valves.
Air Cooling System
Over time debris may accumulate in
cylinder cooling fins and cannot be
observed without partial engine
disassembly. For this reason an
Authorized Warranty Service Center
should clean the air cooling system
per recommended intervals.
