SECTION 1 SAFETY INSTRUCTIONS
1.1 Safety Symbols
These symbols call your attention to instructions concerning your personal safety. Be sure to observe
and follow these instructions.
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.
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.
Before operating the LX50 sawmill, read the operator’s manual and all additional manuals provided
with the machine. Observe all safety instructions included in these manuals!
Always be sure that all safety decals are clean and readable. Replace immediately all damaged
safety decals to prevent personal injury or damage to the equipment. Contact Wood-Mizer Customer
Service or the Wood-Mizer distributor in your area to order a new decal.
IMPORTANT! It is always owner's responsibility to comply with all applicable federal, state and local
laws, rules and regulations regarding the ownership, operation and transport of your LX50 sawmill.
All Wood-Mizer owners are encouraged to become thoroughly familiar with these applicable laws
and comply with them fully while using the sawmill.
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 Instructions
Blade Handling
1
1-2 doc121019 Safety Instructions
1.2 Blade Handling
DANGER! Always disengage the blade and 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. Keep all other persons away from area when coiling,
uncoiling, carrying or changing a blade. Changing blades is safest
when done by one person! Failure to do so may result in serious injury.
1.3 Sawmill Setup
WARNING! Do not set up the sawmill on ground with more than a 10
degree incline. If setup on an incline is necessary, put blocks under
one side of the sawmill or dig out areas for the legs to keep the
machine level. Setting up the sawmill on an incline could cause it to tip
over, resulting in serious personal injury.
WARNING! Keep all persons away from area while loading and
unloading the sawmill. Failure to do so may result in serious injury or
death.
1.4 Sawmill Operation
IMPORTANT! The sawmill is intended for sawing wood only. See
Section Cutting Capacity for log size capacities of the machine.
IMPORTANT! The operator of the sawmill should get adequate
training in 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.
DANGER! Be sure the blade housing is 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 the sawmill or loading and turning logs. Failure to
do so may result in serious injury.
DANGER! Maintain a clean and clear path for all necessary movement
around the sawmill and lumber stacking areas. Failure to do so may
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 may result in serious injury.
WARNING! Always wear eye, ear, respiration and foot protection as
well as safety clothing when operating or servicing the machine.
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 the log is clamped securely before
sawing. Failure to do so may result in serious injury or death.
WARNING! Use ONLY water or alcohol solution 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 loading
a log onto the bed. Failure to do so may result in machine damage.
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. Failure to do so may result in damage to the
up/down system.
CAUTION! Be sure to stop the blade before returning the saw head.
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! If optional loading ramps are used to load a log onto the
sawmill bed, remove them from the brackets on the bed frame before
sawing. The saw head may hit the ramp stops when adjusted for low
cuts and get damaged.
CAUTION! Never clean the blade or 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! The blade should be replaced every two hours of sawmill
operation.
CAUTION! Always wear gloves when handling the blade. Never grab
the blade with bare hands!

Safety Instructions
Refueling
1
1-4 doc121019 Safety Instructions
CAUTION! If the blade breaks during sawmill operation, push the
EMERGENCY STOP button to stop the blade engine/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.
1.5 Refueling
WARNING! Store gasoline away from sawdust and other flammable
materials. Failure to do so may result in serious injury.
1.6 Gas Engine Operation
DANGER! Operate your machine in well ventilated areas only.
Exhaust gases of your engine can cause nausea, delirium and
potentially death unless adequate ventilation is present.
DANGER! Never operate the engine with a fuel or oil leak. The leaking
fuel or oil could potentially come in contact with hot surfaces and ignite
into flames.
DANGER! Engine components can become very hot during operation
(especially exhaust engine components). Avoid contact with any part
of a hot engine. 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 be aware of and take proper protective measures
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 possible injury.
DANGER! Always be sure the blade is disengaged and all persons are
out of the path of the blade before starting the engine. Failure to do so
may result in serious injury.
WARNING! Do not for any reason adjust the engine drive belts or belt
support bracket with the engine running. Doing so may result in
serious injury.
WARNING! Do not operate the engine without proper and operational
spark arrester/muffler. Sparks emitted from the engine exhaust could
ignite surrounding materials, causing serious injury or death.
WARNING! Remove the blade before performing any engine service.
Failure to do so may result in serious injury.
WARNING! Always wear proper and necessary safety equipment
when performing service functions. Proper safety equipment includes

protection.
IMPORTANT! Always dispose of coolant, oil, fuel, oil filters and fuel
filters in a responsible manner and in accordance with local, state and
federal regulations.
WARNING! Always disconnect the sawmill battery cables before
servicing.
DANGER! Batteries expel explosive gases. Keep sparks, flames,
burning cigarettes, or other ignition sources away at all times.
1.7 Sawmill Maintenance
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
forward/reverse movement to bind.
CAUTION! Never use grease on the mast track as it will collect
sawdust.
