6.4.1 Engine Safety

odorless, poisonous gas. Breathing it can cause
unconsciousness or death.

•
Remove the wire from the spark plug before servicing the
engine or equipment to prevent accidental starting.
•
Keep cylinder fins and governor parts free of grass and
other debris that can affect the engine speed.
•
Examine the muffler periodically to make sure it is
functioning effectively. Repair or replace a worn or leaking
muffler, as required.
•
Use fresh gasoline (less than three months old). Stale fuel
creates insoluble solids (deposits) that clog the carburetor
and cause leaks.
•
Before storage, replace fuel that contains ethanol with
an alkylate or appropriate engineered fuel to prevent the
buildup of deposits.
•
Check fuel lines and fittings frequently for cracks or leaks.
Replace if necessary.
•
Store fuel well away from all wood material.
•
Do not place hands or feet near moving or rotating parts.
•
Do not operate the engine in an area where fuel is spilled.
Move the machine away from the spill until the fuel
evaporates. Do not create any sources of ignition in the spill
area.
•
Do not choke the carburetor to stop the engine. Whenever
possible, gradually reduce the engine speed before
stopping.
•
Do not tamper with governor springs, governor links or
other parts that may increase the governed speed. Engine
speed is selected by the original equipment manufacturer.
•
Do not check for spark with the spark plug or spark plug
wire removed.
•
Do not attempt to start the engine with the spark plug
removed. If the engine floods, set the choke control to
OPEN, set the throttle control to FAST, then try to start the
engine again.
•
Do not strike the flywheel with a hard object or metal tool.
This may cause the flywheel to shatter during operation.
Use the correct tools to service the engine.
•
Do not operate the engine without a muffler or heat shield.
Inspect them periodically and replace if damaged.
•
Do not operate the engine with an accumulation of wood
chips, dirt, or other combustible materials in the muffler
area.
•
Do not use the engine on any forest covered, brush
covered, or grass covered unimproved land unless a spark
arrester is installed on the muffler. The arrester must be
maintained in effective working order by the operator. In the
state of California, the previous statement is required by law
(Section 4442 of the California Public Resources Code).
Other states may have similar laws. Federal laws apply on
federal land.
•
Do not touch a hot muffler, cylinder, or fins. Contact may
cause burns.
•
Do not run the engine with the air cleaner or air cleaner
cover removed. Doing this can damage the engine.
