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, operation and towing
of your Wood-Mizer sawmill. All Wood-Mizer mill owners are encouraged to become thor-
oughly familiar with these applicable laws and comply with them fully while using or tow-
ing the mill.
Always properly dispose of all sawing by-products, including sawdust and other debris,
coolant, oil, fuel, oil filters and fuel filters.

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.
WARNING! Do not spin the blade wheels by hand.
Spinning the blade wheels by hand may result in serious
injury.

1.2 Sawmill Setup
WARNING! Chock the trailer wheels to prevent movement
before unhitching it from the towing vehicle. Failure to do so
may result in serious injury or death.
WARNING! Failure to put front outrigger down before mov-
ing cutting head from the rest position 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
may 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 may 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 outrig-
ger 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.

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.
Be sure the blade housing and pulley covers are in place
and secure. Use the safety retainer pin and cable to fasten
blade housing covers.
DANGER! Always keep hands away from moving bandsaw
blade. Failure to do so will result in serious injury.
DANGER! Stay clear of the area between the trailer axle
and saw carriage. 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.
DANGER! Keep all persons out of the path of returning
boards. 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! Be sure the power feed switch is in the neutral
position before turning the key switch to the on (#1) or
accessory (#3) position. This prevents accidental carriage
movement which may cause serious injury or death.

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! The automatic board return is intended to
assist a second operator in removing boards quickly. Do not
use the board return when operating the sawmill alone.
Serious injury, death or damage to the equipment may
result.
WARNING! Never use the board return table as a platform
to stand on. This table is designed and intended to assist in
the removal of boards only. Standing on the table may
result in serious injury.
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 pivot rails, turning arm, clamp, and
toe boards are below bed level before loading a log onto
the bed. Failure to do so may result in machine damage or
cause misalignment.
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! Always make sure the up/down switch moves to
the neutral or off position when released to ensure that the
saw head stops moving. Failure to do so may result in
machine damage.
CAUTION! If the weight of the sawmill exceeds 3,000 lbs
(1361 Kg) for any reason, an auxiliary braking system (such
as electric brakes) must be used. Failure to do so may

result in severe machine damage.
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.

WARNING! Always secure the cutting head with a chain or
a brace before adjusting the up/down chain. The cutting
head may fall, causing 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.
WARNING! Always secure the cutting head with a chain or
a brace before removing the up/down motor belt. The cut-
ting head may fall, causing severe injury or death.
WARNING! Drum switch grease contains Petroleum Hydro-
carbon Lubricant. Eye and skin irritant. If introduced into
eyes, flush with water for at least 15 minutes. If film or irrita-
tion persists, seek medical attention. Wash skin with soap
and water. If ingested, do not induce vomiting - contact a
physician. KEEP OUT OF THE REACH OF CHILDREN.
CAUTION! Do not over-grease the blade guide bearings.
Over-greasing will push the seals out of the bearings caus-
ing premature failure.
CAUTION! Reinstall the track wiper so that it lightly touches
the track rail. If the wiper presses too firmly against the rail,
it can cause the power feed to bind.
CAUTION! Never use grease on the mast rails as it will col-
lect sawdust.
CAUTION! Do not use chain lube. It causes sawdust
buildup in chain links.
CAUTION! Do not over-tension the up/down chain.
Over-tensioning may lead to early failure of the gear
reducer.
CAUTION! Do not overtighten the feed chain. Damage to
the power feed motor may result.

CAUTION! Due to variations in the vertical mast, the pad
spacing may vary throughout the travel of the saw head.
Check the pad spacing at the top and bottom ends of the
mast only. Pads adjusted too tight will cause premature
up/down motor failure.
CAUTION! It is important that the lower stop bolts are prop-
erly adjusted to secure the carriage on the track rail. Failure
to properly adjust the stop bolts can cause saw head dam-
age, especially during mill transportation.
CAUTION! Failure to remove sawdust buildup from the bat-
tery box lid and/or track rail cover could result in damage to
these parts when the saw head is lowered to its lowest
position.
