Do not run engine at full throttle to hurry warm-up after
starting, but idle it a few minutes; this will give the oil a
chance to circulate through the engine.
Do not operate the engine at any time with cooling shroud
removed; this will prevent proper cooling of engine.
To prevent overheating of the engine, and / or possible
damage to the engine, check cooling air screen, fan, and
engine cooling fins every 10 hours for debris, dust and dirt
and clean thoroughly. Under severe dust or dirt conditions
the above should be checked and cleaned at more frequent
intervals.
Check and service air cleaner after 10 hours or oftener
under severe dust and dirt conditions. Service air cleaner as
instructed in engine manufacturer’s manual. Failure to keep
air cleaner clean would allow abrasive particles to enter the
engine causing severe damage. Also, a dirty air cleaner
would prevent the proper air fuel mixture causing the
engine to overheat and cause consequent damage to the
engine.
After every 8 hours of operation check oil level. For correct
grade of oil and proper oil level, see engine manufacturer’s
manual. If the oil in the crankcase is allowed to remain

below the required level, damage to the engine bearings,
cylinder walls, pistons and other moving parts could result
from overheating.
After every 50 hours of operation or oftener under severe
conditions, the engine crankcase should be drained and
refilled with fresh oil. See engine manual for proper
specifications and quantity of oil.
On units with a gasoline strainer, the strainer should be
inspected frequently. If dirt and water are present in the
bowl, the bowl and screen should be removed and cleaned.
When reassembling strainer be sure gasket is in good
condition; use a new gasket if necessary.
When stopping engine do not stop abruptly, but idle the
engine at low RPM for 3 to 5 minutes. The engine will cool
down faster at idle and minimize the danger of overheating.
SPARK PLUG
The spark plug should be cleaned inside and out and
regapped every 100 hours or once each year whichever
occurs first. Check engine manual for correct gap setting.
Replace plug whenever necessary. See engine manual for
correct plug specifications.
