About This Manual
This manual is provided as a supplement to the equipment manufacturer’s manuals. This manual provides
information specific to the use of this equipment on the Wood-Mizer® sawmill. Refer to the sawmill opera-
tor’s manual and manufacturer's manual before attempting to operate this equipment.
IMPORTANT! Read the sawmill operator’s manual and engine manufacturer’s manual for
instructions and safety precautions before operating this equipment.
The information and instructions given in this manual do not amend or extend the limited warranties for the
equipment given at the time of purchase.
SECTION 1 OPERATION
1.1 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.
Operate your engine/machine only in well ventilated areas. The exhaust gases of your
engine can cause nausea, delirium and potentially death unless adequate ventilation is
present.
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 seri-
ous 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.

Maintenance WM doc 3/5/21 2-1
SECTION 2 MAINTENANCE
Refer to the manufacturer’s manual for maintenance intervals and procedures unless otherwise instructed in
this manual. Follow the manufacturer’s recommendations for dusty conditions.
IMPORTANT! This manual only provides information about additional procedures or pro-
cedures to be performed at different time intervals than found in the manufacturer's man-
uals. 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.
2.1 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 possi-
ble injury.
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 fol-
lowing operation. Contact with hot engine components can cause serious burns. There-
fore, 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.
Always wear proper and necessary safety equipment when performing service functions.
Proper safety equipment includes eye protection, breathing protection, hand protection
and foot protection.
This symbol identifies the interval (hours of operation) at which each maintenance procedure should be
performed. "AR" signifies maintenance procedures which should be performed as required.
2.2 Air Filter & Pre-Cleaner
WARNING! Always wear proper and necessary safety equipment when performing ser-
vice functions. Proper safety equipment includes eye protection, breathing protection,
hand protection and foot protection.
Service the pre-cleaner every four hours of operation. Service by gently shaking excess sawdust and debris
from the foam piece.

2-2 WM doc 3/5/21 Maintenance
Clean the air filter (air cleaner element) and pre-cleaner (element wrapper) every eight hours of operation.
See the engine manual for further instructions.
Replace the air filter (cleaner) every 200 hours of operation.
Replace the pre-cleaner (element wrapper) every 2000 hours of operation.
2.3 Fuel Filter
Replace the fuel filter every 100 hours of operation or as required for engine performance.
2.4 Battery
Check the battery electrolyte level every 50 hours of operation. See manufacturer’s manual for instructions.
DANGER! Batteries expel explosive gases. Keep sparks, flames, burning cigarettes, or
other ignition sources away at all times. Always wear safety goggles and a face shield
when working near batteries. Failure to do so will cause serious injury.
WARNING! Battery posts, terminals and related accessories contain lead and lead com-
pounds, chemicals known to the State of California to cause cancer and reproductive
harm. Wash hands after handling.
2.5 Alternator Belt
Adjust the alternator belt as needed.
Check the alternator belt for tension and wear when battery is not charging properly or when the alternator
belt is squealing.

Pivot the alternator away from the motor until the belt has 3/16" (5 mm) deflection with a 5 lb. deflection
force.
Retighten the adjustment bolt.
