SECTION 1 SAFETY & GENERAL INFORMATION
1.1 Safety Symbols
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 persons 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 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 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, oil filters
and fuel filters.
Safety instructions are listed in this section by the following operations:

Sawmill Setup
Sawmill Operation
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 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 15doc120709 Safety & General Information
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 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. Failure 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 wear eye, ear, respiration, and foot protection 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 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 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 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! 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.
CAUTION! The sawmill’s work-stand should be equipped with a 4 kg or
bigger dry powder extinguisher.
1.5 Sawmill Maintenance
CAUTION! The up/down screw bellows should completely cover the
screw. If either of the bellows is damaged, replace it immediately. Before
installing the new bellows, clean the up/down screw and nut thoroughly with
extraction naphtha and then grease them.
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 1-1. Pictogram decals used to warn and inform the user about danger in the LT15.

1.7 Blade Sizes
See Table 1-3. 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.
See The Blade Handbook for blade hook angle, tooth height, and tooth set specifications.
1.8 Cutting Capacity
See Table 1-4. The log size capacities of the LT15 sawmills are listed below.
See Table 1-5. The performance capacity of the LT15 sawmill is listed below. Peak cutting rates are
measured in 12” (30 cm) wide red oak and represent the capability of the sawmill only. Rates based on using
Tru-Sharp 1 1/4” x .042 blades.

1. The noise level measurement was taken in accordance with PN-EN ISO 3746 Standard . The noise
exposure level given above concerns an 8-hour work day.
2. The measured values refer to emission levels, not necessarily to noise levels in the workplace. Although
there is a relation between emission levels and exposure levels, it is not possible to determine with certainty
if preventives are needed or are not needed. The factors affecting a current level of noise exposure during
work are inter alia room characteristics and characteristics of other noise sources, e.g. number of machines
and machining operations nearby. Also, the permissible exposure level value may vary depending on
country. This information enables the machine’s user to better identify hazards and a risk .
