WARNING!

HM126 Operator’s Manual
WORK AREA
•Keep work area clean, free of clutter and well lit. Cluttered and dark work areas can
cause accidents.
•Do not use your sawmill where there is a risk of causing a fire or an explosion; e.g. in
the presence of flammable liquids, gasses, or dust. Power tools create sparks which may
ignite the dust or fumes.
•Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control, therefore, visitors should remain a safe distance from the work area.
•Be aware of all power lines, electrical circuits, water pipes and other mechanical hazards in
your work area, particularly those hazards below the work surface hidden from the operator’s
view that may be unintentionally contacted and cause personal harm or property damage.
•Be alert of your surroundings. Using power tools in confined work areas may put you
dangerously close to cutting tools and rotating parts.
INTERNAL COMBUSTION ENGINE SAFETY
HM126-MY2021-EN: Rev F
Page of7112
14-Jul-2021
Internal combustion engines present special hazards during operation and
fuelling. Read and follow the warning instructions in the engine Owner’s
Manual and the safety guidelines below. Failure to follow the warnings
and safety standards could result in severe injury or death.
•DO NOT run the machine indoors or in an enclosed area such as a deep
trench unless adequate ventilation, through such items as exhaust fans
or hoses, is provided. Exhaust gas from the engine contains poisonous
carbon monoxide gas (CO); exposure to carbon monoxide can cause
loss of consciousness and may lead to death.
•DO NOT smoke while operating the machine.
•DO NOT smoke when refuelling the engine.
•DO NOT refuel a hot or running engine.
•DO NOT refuel the engine near an open flame.
•DO NOT spill fuel when refuelling the engine.
•DO NOT run the engine near an open flame.
•ALWAYS refill the fuel tank in a well-ventilated area.
•ALWAYS replace the fuel tank cap after refuelling.
•ALWAYS check the fuel lines and the fuel tank for leaks and cracks
before starting the engine. Do not run the machine if fuel leaks are
present or the fuel lines are loose.
•ALWAYS avoid contact with hot fuel, oil, and exhaust fumes.
WARNING!

HM126 Operator’s Manual
PERSONAL SAFETY
•Stay alert, watch what you are doing and use common sense when operating a power
tool. Do not use a power tool when you are tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power tools may result in serious
personal injury.
•Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be
caught in moving parts. Air vents often cover moving parts and should be avoided.
•Use safety apparel and equipment. Use safety goggles or safety glasses with side shields
which comply with current national standards, or when needed, a face shield. Use a dust
mask in dusty work conditions. This applies to all persons in the work area. Also use non-
skid safety shoes, hardhat, gloves, dust collection systems, and hearing protection when
appropriate.
•Do not overreach. Keep proper footing and balance at all times.
•Remove adjusting keys or wrenches before connecting to the power supply or turning on
the tool. A wrench or key that is left attached to a rotating part of the tool may result in
personal injury.
•Never make blade guide adjustments, remove or install blades, or conduct any other
maintenance or make any other adjustments while the engine is running. Always shut
the engine off, remove the ignition key, and turn the engine off before carrying out any of the
aforementioned procedures. Consult your engine manual for safe shutdown procedures to
prevent accidental ignition.

HM126 Operator’s Manual
TOOL USE AND CARE
•Always be sure the operator is familiar with proper safety precautions and operation
techniques before using machine.
•Never touch the engine or muffler while the engine is on or immediately after it has been
turned off. These areas get extremely hot and can cause burns.
•Always close the fuel valve on the engine when the machine is not in use.
•Do not force the tool. Tools do a better and safer job when used in the manner for which
they are designed.
•Never use the sawmill with a malfunctioning switch or throttle. Any power tool that cannot
be controlled with the switch is dangerous and must be repaired before using.
•Turn off the engine and place the switch in the locked or off position before servicing,
adjusting, installing accessories or attachments, or storing. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
•Secure logs with the log screw clamping device instead of with your hand or another
individual’s help. This safety precaution allows for proper tool operation using both hands.
•Storing sawmill. When the sawmill is not in use, store it in a dry, secure place or keep well
covered and out of the reach of children. Inspect the sawmill for good working condition prior
to storage and before re-use.
•Maintain your sawmill. It is recommended that the general condition of the sawmill be
examined before it is used. Keep your sawmill in good repair by adopting a program of
conscientious repair and maintenance in accordance with the recommended procedures
found in this manual. If any abnormal vibrations or noise occurs, turn the sawmill off
immediately and have the problem corrected before further use.
•Keep saw blades sharp and clean. Properly maintained bandsaw blades are less likely to
bind and are easier to control.
•Cleaning and Lubrication. Use only soap and a damp cloth to clean your sawmill. Many
household cleaners are harmful to plastic and rubber components on the sawmill.
•Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for another sawmill may create a risk of injury when used
on the sawmill.
•Always operate machine with all safety devices and guards in place and in working order.
DO NOT modify or make changes to safety devices. DO NOT operate machine if any safety
devices or guards are missing or inoperative.
•Never leave sawmill running unattended.
•Coiled blades can spring apart with considerable force and unpredictably in any
direction. Always deal with coiled blades, including those packaged in boxes, with the
utmost care.
•Never use the equipment to cut anything other than lumber or for any purpose other than
cutting lumber as described in this manual.

EQUIPMENT OPERATION
1. Wear heavy-duty work gloves, ANSI-approved goggles behind a
full face shield, steel-toed work boots, hearing protection, and a
dust mask.
2. Operate only with assistance.
3. Cut-off branches from the lumber to be processed.
4. Place the lumber to be cut on the track supports.
5. Clamp the lumber firmly in place using the included log clamps and supports.
6. Fill the lubrication tank with clean water. Add no more than a teaspoon of liquid dish soap
per full tank. The soap helps keep the blade clean(er) when excess pitch builds up.
7. Start and operate the engine according to the provided engine manual.
8. Depress the throttle to bring the blade up to speed—the throttle should be fully depressed
while the saw is under load.
9. Roll the head assembly slowly along the track and against the lumber to make the cut.
10. Trim off the rounded sides of the log.
11. When the log is squared-off, boards or posts can be cut to standard or custom
specifications.
12. To prevent accidents, turn off the engine and disconnect its spark plug wire after use. Wait
for the engine to cool, clean external parts with a clean cloth, then store the equipment out
of children’s reach.
HM126-MY2021-EN: Rev F
Page of10 112
14-Jul-2021
To avoid death or serious injury, do not cut lumber containing
embedded foreign objects such as nails, metal fragments, etc.
WARNING!
The operator and any assistants must stay clear of the front and back
of the blade whenever the engine is on.
WARNING!

HM126 Operator’s Manual
MAINTENANCE
Proper and routine maintenance is critical to operator safety, achieving good milling results, and
to prolong the life of your investment.
•Band Wheel Bearings — Inspect before use to ensure they are not worn. Bearings are
sealed and do not need to be greased.
•Blade Guide Bearings — Inspect before use for excessive grooves or scoring in the
bearing case. Replace if necessary.
•Blade Tension — Grease tension handle threads when dry or as required. Use multi-
purpose, extreme-pressure grease.
•Log Clamps — Spray the cam mechanism with dry silicone spray frequently.
•Belts — Periodically check the condition and wear of the drive and idler belt. Ensure that
the blade does not ride on the band wheels.
•Drive Belt — Periodically check the tension of the drive belt.
•Carriage Posts (Front) — Spray posts before use with a silicone spray lubricant such as
“WD-40 Water Resistant Silicone Spray,” “3-in-One Silicone Spray Lubricant," or “Jig-A-
Loo.”
•Band Wheel Guards — Routinely remove any build-up of sawdust that may collect inside
the band wheel guards.
•Lubrication Tank — Fill with clean water. Add a teaspoon of liquid dish soap if pitch builds
up on the blade. In winter months windshield washer fluid can be used. Do not leave
water in tank if temperature falls below 32°F [0˚C].
•Blade Lubricant — Never use diesel fuel or kerosene as blade lubricant. These
substances lead to premature wear of your belts and poor sawing performance. For winter
operation, replace the water with windshield washer fluid.
•Engine — Check the engine oil level before each use and maintain the engine per the
instructions set out by the engine manufacturer in the engine manual. The engine is
equipped with an oil alert system and will not start without adding oil before starting.
•Lifting Cables — Before, during, and after operation, regularly inspect the cables for any
wear or kinks. Ensure that the cables are in perfect condition. Oil the coiled part of the
cable often to prevent premature wear. Replace with new cables as necessary.
