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 indi-
cates 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, warn-
ings, 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 saw-
mill. All Wood-Mizer mill owners are encouraged to become thoroughly familiar with these applica-
ble 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.
Safety instructions are listed in this section by the following operations:
Blade Handling
Sawmill Setup
Sawmill Operation
Sawmill Maintenance
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 seri-
ous injury.
WARNING! Always wear gloves and eye protection when handling
bandsaw blades. Changing blades is safest when done by one per-
son! Keep all other persons away from area when coiling, carrying or
changing a blade. Failure to do so may result in serious injury.

Sawmill Setup
Safety & General Information 15doc012809 1-2

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 seri-
ous 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 move-
ment 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 disengage the clutch/brake mechanism when-
ever the sawmill is not cutting. Failure to do so may 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 saw-
ing. Failure to do so may result in serious injury or death.

1-3 15doc012809 Safety & General Information
WARNING! Use ONLY water 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 load-
ing a log onto the bed. Failure to do so may result in machine dam-
age.
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 sawmill’s work-stand should be equipped with a 4 kg
or bigger dry powder extinguisher.
1.4 Sawmill Maintenance
WARNING! Always secure the cutting head with a chain or a brace
before adjusting the up/down chain. The cutting head may fall, caus-
ing severe injury or death.
WARNING! Always secure the cutting head with a chain or a brace
before adjusting the mast pads. The cutting head may fall, causing
severe injury or death.
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 saw-
dust.

1.6 Blade Sizes
See Table 1-3. Wood-Mizer TRU•SHARP™ offers three types of blades to provide efficient saw-
ing 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.
1.7 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.
