clean cloths to remove dirt, dust, oil, grease, etc.
OPERATION
HIGH ALTITUDE OPERATION
Specific modifications are needed for high-altitude operation
for equipment operating in altitudes greater than 3000 feet
above sea level. Please contact your authorized service center
for important information regarding these modifications.
Operating this engine without the proper altitude modification
may increase the engine's emissions and decrease fuel
economy and performance.

MAINTENANCE

WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which could result in serious personal
injury.
Before running the engine, perform the following pre-
operation steps:
 Check that all bolts, nuts, etc., are securely tightened.
 Make sure the air filter is clean.
 Check both the engine lubricant level and the fuel tank
level; refill as needed.
 Inspect the work area for hazards.
 If there is excessive noise or vibration, stop the unit
immediately.

NOZZLE MAINTENANCE

Excessive pump pressure (a pulsing sensation felt while
squeezing the trigger) may be the result of a clogged or
dirty nozzle.

supply. Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
 To free any foreign materials clogging or restricting the
nozzle, blow out or remove debris with a straightened
paper clip or fine needle.
 Using a garden hose, flush debris out of nozzle by back
flushing (running the water through the nozzle backwards
or from the outside to the inside).
 Reconnect the nozzle to the spray wand.
 Turn on the water supply and start the engine.
