SECTION 1 SAFETY & GENERAL INFORMATION
This symbol calls your attention to instructions concerning your personal safety. Be sure
to observe and follow these instructions. This symbol accompanies a signal word. The
word DANGER indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury. WARNING suggests a potentially hazardous situation
which, if not avoided, could result in death or serious injury. CAUTION refers to potentially
hazardous situations which, if not avoided, may result in minor or moderate injury to per-
sons or equipment. Read all safety instructions before operating this equipment and
observe all safety warnings!
Warning stripes are placed on areas where a single decal would be insufficient. To avoid
serious injury, keep out of the path of any equipment marked with warning stripes.
Read and observe all safety instructions before operating this equipment! Also read any
additional manufacturer’s manuals and observe any applicable safety instructions includ-
ing dangers, warnings, and cautions.
Always be sure that all safety decals are clean and readable. Replace all damaged safety
decals to prevent personal injury or damage to the equipment. Contact your local distribu-
tor, or call your Customer Service Representative to order more decals.
IMPORTANT! It is always the owner's responsibility to comply with all applicable federal,
state and local laws, rules and regulations regarding the ownership and operation of your
Wood-Mizer sawmill. All Wood-Mizer mill owners are encouraged to become thoroughly
familiar with these applicable laws and comply with them fully while using the mill.
Always properly dispose of all sawing by-products, including sawdust and other debris,
coolant, oil, fuel, oil filters and fuel filters.

1-2 15doc120103 Safety & General Information
1.1 Blade Handling
DANGER! Always disengage the blade and shut off the
sawmill engine before changing the blade. Failure to do so
will result in serious injury.
WARNING! Always wear gloves and eye protection when
handling bandsaw blades. Changing blades is safest when
done by one person! Keep all other persons away from
area when coiling, carrying or changing a blade. Failure to
do so may result in serious injury.
1.2 Sawmill Setup
WARNING! Do not set up the mill on ground with more than
a 10 degree incline. If setup on an incline is necessary, put
blocks under one side of the mill or dig out areas for the
legs to keep mill level. Setting up the mill on an incline
could cause it to tip over, resulting in serious personal
injury.
WARNING! Keep all persons out of the path of the saw
head while loading and unloading the sawmill. Failure to do
so may result in serious injury or death.

1.3 Sawmill Operation
DANGER! Make sure all guards and covers are in place
and secured before operating or towing the sawmill. Failure
to do so may result in serious injury.
DANGER! Be sure the blade housing and pulley covers are
in place and secured.
DANGER! Always keep hands away from moving bandsaw
blade. Failure to do so will result in serious injury.
DANGER! Keep all persons out of the path of moving
equipment and logs when operating sawmill or loading and
turning logs. Failure to do so will result in serious injury.
DANGER! Maintain a clean and clear path for all necessary
movement around the mill and lumber stacking areas. Fail-
ure to do so will result in serious injury.
DANGER! Always be sure the blade is disengaged and all
persons are out of the path of the blade before starting the
engine or motor. Failure to do so will result in serious injury.
WARNING! Always disengage the clutch/brake mechanism
whenever the sawmill is not cutting. Failure to do so may
result in serious injury.
WARNING! Always wear eye, ear, respiration, and foot pro-
tection when operating the sawmill. Failure to do so may
result in serious injury.
WARNING! Secure all loose clothing and jewelry before
operating the sawmill. Failure to do so may result in serious
injury or death.
WARNING! Always make sure log is clamped securely
before sawing. Failure to do so may result in serious injury
or death.
WARNING! Use ONLY water with the water lube acces-
sory. Never use flammable fuels or liquids. If these types of
liquids are necessary to clean the blade, remove it and
clean with a rag. Failure to do so may result in serious
injury or death.
CAUTION! Be sure the log clamps are all the way down
before loading a log onto the bed. Failure to do so may

result in machine damage.
CAUTION! Before loading a log, be sure the cutting head is
moved far enough forward so the log does not hit it. Failure
to do so may result in machine damage.
CAUTION! Do not try to force the saw head beyond its
upper and lower travel limits. Damage to the up/down sys-
tem may result.
CAUTION! Be sure to stop the blade when returning the
carriage. This will not only prevent the blade from being
pulled off and ruined by a wood sliver, but also will increase
the life of the blade.
CAUTION! The saw head will hit the spring-loaded ramp
stops when adjusted for low cuts. Remove the loading
ramps before sawing to prevent damage to the saw head
and/or blade guide arm.
