SECTION 2 OPERATION
2.1 Starting The Engine
Engine Start
DANGER! Always be sure the blade is disengaged and all
persons are out of the path of the blade before starting the
engine. Failure to do so will result in serious injury.
DANGER! Operate your engine/machine only in well venti-
lated areas. The exhaust gases of your engine can cause
nausea, delirium and potentially death unless adequate
ventilation is present.
DANGER! Never operate an engine with a fuel or oil leak.
The leaking fuel or oil could potentially come in contact with
hot surfaces and ignite into flames.
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 for specific
temperature ranges.
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 on (#1) position.
4. Turn the key switch to the start (#2) position and release.
Engine Shutoff
1. Disengage the clutch handle to stop the blade if necessary.
2. Turn the key switch to the off (#0) position.

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 dif-
ferent time intervals than found in the manufacturer's manu-
als. Refer to the manufacturer's manual for complete
maintenance instructions.
WARNING! Clean sawdust from all guards, vents, con-
trol 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. Contact 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 protec-
tion, hand protection and foot protection.
