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.
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.

SECTION 3 MAINTENANCE
Refer to the manufacturer’s manual for maintenance intervals and procedures unless oth-
erwise instructed in this manual. Follow the manufacturer’s recommendations for dusty
conditions.
IMPORTANT! This manual only provides information about additional
procedures or procedures to be performed at different time intervals
than found in the manufacturer's manuals. Refer to the manufacturer's
manual for complete maintenance instructions.
WARNING! Clean sawdust from all guards, vents, control
boxes, or any area where sawdust may gather after every
shift. Failure to do so may result in fire, causing death or
serious injury.
3.1 Safety
Use caution when performing maintenance or service to the engine.
DANGER! Always be aware of and take proper protective measures
against rotating shafts, pulleys, fans, etc. Always stay a safe distance
from rotating members and make sure that loose clothing or long hair
does not engage rotating members resulting in possible injury.
DANGER! Engine components can become very hot during operation.
Avoid contact with any part of a hot engine. The exhaust components
of your engine are especially hot during and following operation. Con-
tact with hot engine components can cause serious burns. Therefore,
never touch or perform service functions on a hot engine. Allow the
engine to cool sufficiently before beginning any service function.
WARNING! Remove the blade before performing any engine service.
Failure to do so may result in serious injury.
WARNING! Always wear proper and necessary safety equipment
when performing service functions. Proper safety equipment includes
eye protection, breathing protection, hand protection and foot protec-
tion.
This symbol identifies the interval (hours of operation) at which each maintenance pro-
cedure should be performed. "AR" signifies maintenance procedures which should be
