11. CONDUCTING SAFETY CHECKS & MAINTENANCE
A When inspecting the engine or servicing, place the
engine on a large flat surface. DO NOT work on anything
that is supported ONLY by lift jacks or a hoist. Always use
blocks or the correct stands to support the engine before
servicing.
A Disconnect the battery from the engine before
conducting service. Put a "DO NOT OPERATE!" tag on
the key switch to avoid accidental starting.
A To avoid sparks from an accidental short circuit always
disconnect the battery's ground cable (-) first and
reconnect it last.
A Be sure to stop the engine and remove the key when
conducting daily and periodic maintenance, service and
cleaning.
A Check or conduct maintenance after the engine, coolant,
muffler, or muffler cover have cooled off completely.
A Always use the appropriate tools and fixtures. Verify that
they are in good condition before performing any service
work. Make sure you understand how to use them before
service.
A Use ONLY correct engine barring techniques for
manually rotating the engine. DO NOT attempt to rotate
the engine by pulling or prying on the cooling fan and V-
belt. This practice can cause serious personal injury or
premature damage to the cooling fan and belt.
A Replace fuel pipes and lubricant pipes with their hose
clamps every 2 years or earlier whether they are
damaged or not. They are made of rubber and age
gradually.
A When servicing is performed together by two or more
persons, take care to perform all work safely.
A Keep a first aid kit and fire extinguisher handy at all times.
