2.2 Safety Instructions
NOTE: ONLY safety instructions regarding personal injury are listed in this section. Cau-
tion statements regarding only equipment damage appear where applicable throughout

OBSERVE SAFETY INSTRUCTIONS
IMPORTANT! Read the entire Operator's Manual before operating
the sawmill. Take notice of all safety warnings throughout this man-
ual and those posted on the machine. Keep this manual with this
machine at all times, regardless of ownership.
Also read any additional manufacturer’s manuals and observe any
applicable safety instructions including dangers, warnings, and
cautions.
Only persons who have read and understood the entire operator's
manual should operate the sawmill. The sawmill is not intended for
use by or around children.
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.

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.

HANDLE FUEL/LUBRICANTS SAFELY
DANGER! Due to the flammable nature of fuel and oil, never
smoke, weld, grind or allow sparks near your engine or storage
tanks, especially during times of fueling.
DANGER! Never allow fuel to spill on a hot engine during fueling
operations or otherwise. The hot temperature of your engine could
induce a fire or explosion.
WARNING! Store gasoline away from sawdust and other flamma-
ble materials. Failure to do so may result in serious injury.
WARNING! Use ONLY water and Wood-Mizer Lube Additive with
the water lube accessory. Never use flammable fuels or liquids
such as diesel fuel. If these types of liquids are necessary to clean
the blade, remove it and clean with a rag. Failure to do so can
damage the equipment and may result in serious 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 med-
ical attention. Wash skin with soap and water. If ingested, do not
induce vomiting - contact a physician. KEEP OUT OF THE REACH
OF CHILDREN.
DISPOSE OF SAWING BY-PRODUCTS PROPERLY
IMPORTANT! Always properly dispose of all sawing by-products,
including sawdust and other debris, coolant, oil, fuel, oil filters and
fuel filters.

2-5 2804doc030317 Safety
USE CAUTION WHEN WORKING WITH BATTERIES
DANGER! Batteries expel explosive gases. Keep sparks, flames,
burning cigarettes, or other ignition sources away at all times.
Always wear safety goggles and a face shield when working near
batteries. Failure to do so will cause serious injury. 1
WARNING! Battery posts, terminals and related accessories con-
tain lead and lead compounds, chemicals known to the State of
California to cause cancer and reproductive harm. Wash hands
after handling.
WARNING! Charge the battery in a well ventilated area. Do not
attempt to charge a frozen battery.
Use extreme care to avoid spilling or splashing electrolyte (which is
dilute sulfuric acid) as it can destroy clothing and burn the skin. If
electrolyte is spilled or splashed on clothing or the body, it should
be neutralized immediately and then rinsed with clean water. A
solution of baking soda, or household ammonia, and water may be
used as a neutralizer.
Electrolyte splashed into the eyes is extremely dangerous. If this
should happen, force the eye open and flood it with cool, clean
water for approximately fifteen minutes. A doctor should be called
immediately when the accident occurs and “on-the-spot” medical
attention given if possible. If a doctor cannot come to the scene of
the accident immediately, follow his instructions concerning actions
to take. Do not add eye drops or other medication unless advised
to do so by the doctor. Do not place a battery or acid within the
reach of children. If acid (electrolyte) is taken internally drink large
quantities of water or milk. Follow with milk of magnesia, beaten
egg or vegetable oil. Call a physician immediately.
If electrolyte is spilled or splashed on any surface of the machine, it
should be neutralized and rinsed with clean water.
CAUTION! Do not overcharge the battery. Overcharging may
reduce the overall service life of the battery.
CAUTION! Be sure the battery is fully charged before transporting
the sawmill. If the battery is not fully charged, excessive vibration
could reduce the overall service life of the battery.

CAUTIONS FOR 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 outrigger legs to keep
mill level. Setting up the mill on an incline could cause it to tip over,
resulting in serious personal injury.
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! Put front outrigger down before moving saw head from
the rest position. Failure to do so may result in serious injury.
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 out-
riggers are intended to support the saw frame with assistance from
the trailer.
WARNING! The adjustable outriggers supplied with portable saw-
mills are not intended for setup on concrete or other hard surfaces.
Long-term use of the adjustable outriggers on hard surfaces may
cause the outriggers to fail, causing the sawmill to drop. This could
result in possible serious injury or death.
If setting the sawmill up on concrete or other hard surface, replace
the adjustable outrgger legs with stationary legs.
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.

CHECK SAWMILL BEFORE 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 hous-
ing covers.
WARNING! Use both hands to operate the blade tensioner handle.
Be sure the handle lock engages (flips down) after tensioning the
blade. Failure to do so may result in injury.

KEEP PERSONS AWAY
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. 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.

2-9 2804doc030317 Safety
KEEP HANDS AWAY
DANGER! Always disengage the blade and shut off the sawmill
engine before changing the blade. Failure to do so will result in
serious injury.
DANGER! Engine components can become very hot during opera-
tion. Avoid contact with any part of a hot engine. The exhaust com-
ponents of your engine are especially hot during and following
operation. Contact with hot engine components can cause serious
burns. Therefore, never touch or perform service functions on a hot
engine. Allow the engine to cool sufficiently before beginning any
service function.
DANGER! Always keep hands away from moving bandsaw blade.
Failure to do so will result in serious injury.
DANGER! Always be aware of and take proper protective mea-
sures against rotating shafts, pulleys, fans, etc. Always stay a safe
distance from rotating members and make sure that loose clothing
or long hair does not engage rotating members resulting in possi-
ble injury.
WARNING! Do not spin the blade wheels by hand. Spinning the
blade wheels by hand may 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 seri-
ous injury.
WARNING! Do not for any reason adjust the engine drive belt with
the engine running. Doing so may result in serious injury.
WARNING! Always keep clear of exiting sawdust. Keep hands,
feet and any other objects away from the sawdust chute when
operating sawmill. Failure to do so may result in serious injury.
