1-1 HDSdoc030722 Safety & General Information
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 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, 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.
Safety instructions are listed in this section by the following operations:
Blade Handling
Sawmill Setup
Sawmill Operation
Sawmill Maintenance

Safety & General Information
Blade Handling
Safety & General Information HDSdoc030722 1-2
1
1.1 Blade Handling
DANGER! Shut off the sawmill motor 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 moving 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 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.

Safety & General Information
Sawmill Operation

1-3 HDSdoc030722 Safety & General Information
1.3 Sawmill Operation
IMPORTANT! The sawmill is intended for sawing wood only. See
Section 1.8 for log size capacities of the machine.
IMPORTANT! The operator of the sawmill should get adequate
training in the operation and adjustment of the machine.
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. 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.
DANGER! Keep all persons out of the path of returning boards. 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! Be sure the power feed switch is in the neutral position
before turning the key switch to the (#1) or (#2) 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.

Safety & General Information
Sawmill Operation
Safety & General Information HDSdoc030722 1-4

WARNING! Always leave loading arm halfway up while log is on
sawmill bed. 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 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 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! Avoid leaving hydraulic levers engaged while machine is
being operated. Doing so may cause battery drainage!
CAUTION! Be careful when manually lowering the log loader. Do not
drop the loader onto the ground or perform any action which might
break the velocity fuse valves on the loader cylinders. These valves
control hydraulic flow and are necessary to prevent the loading arm
from collapsing during use.
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! 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! Move the hydraulic clamp and turner to provide maximum
ground clearance before towing. Failure to do so may result in damage
to the sawmill.
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.

DANGER! Any arbitrary repairs of the electric installation could result
in serious injury or death.
DANGER! Any damaged electric parts, especially the wires supplying
the power feed motors must be repaired by a qualified electrician.
DANGER! Any repairs done to the electric installation may be done by
a qualified electrician with the power off.
DANGER! The electric connector must be equipped with a safety
device to protect against shock.
DANGER! The electric connector must be installed by a qualified
electrician.
DANGER! Do not operate the sawmill with an open electric box.
DANGER! In the event that water appears in the electric box further
work on the sawmill may result in electric shock as well as damage to
the power feed motor.
DANGER! The electric box door must always be closed, even when
the sawmill is not in use.
DANGER! Always disconnect the power when the sawmill has been
not in use for a long period.
DANGER! Any maintenance or repair must be done with the power off
(the plug must be taken out of the outlet).
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.
CAUTION! Be sure all safety plates are clean and readable. For new
safety plates please contact your local distributor.
CAUTION! Log clamp have to be fully open before towing. Failure to
do so may result in damage to log clamp assembly during
transportation.
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! Never clean the blade or the blade wheels with a brush or
a scraper during sawmill operation.
CAUTION! Before installation of the blade, inspect it for damage and
cracks. Use only properly sharpened blades. Always handle the blade
with extreme caution. Use suitable carrier equipment for transporting
the blades.

CAUTION! Always wear gloves when handling the blade. Never grab
the blade with bare hands!
CAUTION! If the blade breaks during sawmill operation, push the
EMERGENCY STOP button to stop the blade motor and wait
10 seconds before you open the blade housing cover.
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, 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 cutting head may fall,
causing severe injury or death.
WARNING! Drum switch grease contains Petroleum Hydrocarbon
Lubricant. Eye and skin irritant. If introduced into eyes, flush with water
for at least 15 minutes. If film or irritation 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 causing
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 collect
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 over-tighten the feed chain. Damage to the power
feed motor may result.

CAUTION! Do not over-tighten the contact set screws on the hydraulic
valve assembly. Over-tightening may cause the threads in the screw
hole to strip.
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 properly
adjusted to secure the carriage on the track rail. Failure to properly
adjust the stop bolts can cause saw head damage, especially during
mill transportation.
CAUTION! Pressure should not exceed 2000 psi. If it does, the amp
draw will rise above the design maximum of 200 amps, and could
cause battery and system problems. Pressure above 2000 p.s.i. may
also damage the hydraulic hoses.
CAUTION! Failure to remove sawdust buildup from the battery box lid
and/or track rail cover could result in damage to these parts when the
saw head is lowered to its lowest position.
