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
the manual.
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.

WEAR SAFETY CLOTHING
WARNING! Secure all loose clothing and jewelry before operating
the sawmill. Failure to do so may result in serious injury or death.
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.
WARNING! Always wear eye, ear, respiration, and foot protection
when operating or servicing the sawmill.
KEEP SAWMILL AND AREA AROUND SAWMILL CLEAN
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.

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.

USE CAUTION WHEN WORKING WITH BATTERIES (GAS & DIESEL SAWMILLS
ONLY)
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.
