SECTION 1 SAFETY & GENERAL INFORMATION
1.1 Safety Symbols
The following symbols and signal words call 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 or towing the mill.
Always properly dispose of all sawing by-products, including sawdust and other debris, coolant, oil, fuel, oil
filters and fuel filters.

Sawmill Maintenance
1.2 Blade Handling
DANGER! Always disengage the blade and shut off the sawmill engine before
changing the blade. Failure to do so may 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.
WARNING! Do not spin the blade wheels by hand. Failure to do so may result
in serious injury.
1.3 Sawmill Setup
WARNING! Chock the trailer wheels to prevent movement before unhitching it
from the towing vehicle. Failure to do so will result in serious injury or death.
WARNING! Put front outrigger down before moving cutting head from the rest
position. Failure to do so may result in serious injury.
WARNING! Securely fasten the feet of a stationary sawmill to the floor before
operating the sawmill. Failure to do so will result in serious injury or death.
WARNING! Always make sure the trailer is supporting the sawmill frame when
operating a sawmill with adjustable outriggers. Failure to do so will result in
serious injury or death. The adjustable outriggers are intended to support the
saw frame with assistance from the trailer.
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 outrigger legs to keep mill level. Setting up the mill on an
incline could cause it to tip over, resulting in serious personal injury.
CAUTION! Changes in temperature could cause increased pressure in the
blade tensioner and loss of fluid from the gauge. Release the blade tension
when the mill is not in use to avoid damage to the tensioner.
CAUTION! Dismount hydraulic log turner leg before transportation in mobile
sawmills.
