SECTION 2 OPERATION
2.1 Starting The Engine
DANGER! Ensure the blade is disengaged and all persons are out of
the path of the blade before starting. Failure to do so will result in death
or serious injury.
DANGER! Operate your engine only in well ventilated areas. The
exhaust gases of your engine can cause nausea, delirium, and poten-
tially death unless adequate ventilation is present.
DANGER! Never operate an engine with a fuel or oil leak. This is a fire
hazard, which may cause serious injury or death.
WARNING! Do not operate engine without proper and operational
spark arrester/muffler. Sparks emitted from the engine exhaust could
ignite surrounding materials, causing serious injury or death.
CAUTION! EPA Compliant Gas Tanks Only: Always relieve all fuel
pressure inside the tank prior to filling or connecting fuel fittings. Fail-
ure to do so may result in fuel spillage.
CAUTION! EPA Compliant Gas Tanks Only: Disconnect the fuel tank
when not in use, or engine flooding or fuel spillage may result.
1. See the engine manufacturer’s manual for lubricating oil recommendations.
2. Use #2 or better quality diesel fuel for above freezing starting. Use a #1 quality diesel fuel
for below freezing starting.
3. Turn the key switch to the start (#2) position and release.
1. Turn fuel shut-off valve to ON position
2. Turn engine on/off switch to ON position

2-2 WMdoc080618 Operation
Warm engine: Place throttle control midway between SLOW and FAST positions. Return
choke to OFF position as soon as engine starts. A warm engine usually does not require
choke on.
4. Slowly pull starter handle until just past compression-STOP! Return starter handle; fi rmly
pull straight out to avoid excessive rope wear from starter rope guide.
5. Gradually return choke control to OFF position after engine starts and warms up.
Engine/equipment may be operated during warm up period, but it may be necessary to
leave choke partially on until engine warms up.
For more information, see the engine manufacturer’s operation manual.
