SECTION 1 SAFETY
1.1 Safety Symbols
This symbol calls your attention to instructions concerning your personal safety. Be sure
to observe and follow these instructions.
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
persons or equipment.
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
including 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
distributor, 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, operation and towing
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.

Blade Handling

1-2 15doc052207 Safety
1.2 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.
1.3 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.
1.4 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 is in place and
secured. Do not open the blade housing, when the blade is
engaged.
DANGER! Always keep hands away from moving bandsaw
blade. Failure to do so may 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 may result in serious injury.
DANGER! Maintain a clean and clear path for all necessary
movement around the mill and lumber stacking areas.
Failure to do so may result in serious injury.
WARNING! 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 may result in serious
injury.
WARNING! Secure all loose clothing and jewelry before
operating the sawmill. Failure to do so will result in serious
injury or death.
WARNING! Always make sure log is clamped securely
before sawing. Failure to do so will result in serious injury or
death.
WARNING! Use ONLY water or alcohol solution with the
water lube accessory. 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 will 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
system 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! Remove the optional loading ramps before
sawing.

1.5 Sawmill Maintenance
CAUTION! Reinstall the track wiper so that it lightly touches
the track bar. If the wiper presses too firmly against the bar,
it can cause the power feed to bind.
CAUTION! Never use grease on the mast rails as it will
collect sawdust.

See Table 1-2. Wood-Mizer TRU•SHARP™ offers three types of blades to provide
efficient sawing for all models of sawmills. The engine/motor size of your sawmill and the
type of wood you saw should determine which blade you choose for optimum
performance.
