SAVE THESE INSTRUCTIONS
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, so visitors should remain at 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 may 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
Page of 449
WARNING!
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; 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 open flames.
• 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.


PERSONAL SAFETY
•Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while 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 over reach. 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 when the engine is running. Always shut the
engine off, remove the ignition key, and keep the engine off before carrying out any of the
aforementioned procedures. Consult your engine manual for safe shutdown procedures to
prevent accident ignition.

TOOL USE AND CARE
•Always be sure operator is familiar with proper safety precautions and operation techniques
before using the machine.
•Never touch the engine or muffler while the engine is on or immediately after it has been turned
off. These areas get hot and may cause burns.
•Always close fuel valve on engines when machine is not being operated.
•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 mild 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 this 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 the 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.

MAINTENANCE
Proper and routine maintenance is critical to operator safety, achieving good milling results and to
prolonging 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 threads of tensioning “T” handle when dry or as required. Use multi-
purpose, extreme-pressure grease.
•Log Screws — Grease 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.
•Saw Head Vertical Posts — Spray posts before use with a silicone spray lubricant such as 3-in-1
or Jig-A-Loo.
•Band Wheel Guards — Routinely remove any build-up of sawdust that may collect inside the
band wheel guards.
•Lubrication Tank — Only fill with a water and dish soap mixture or in winter months, use
windshield washer fluid. Do not leave lubricant in tank if temperature falls below 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 operations, replace the
water lubricant with windshield washer fluid.
•Engine — Check the engine oil level before each use and maintain the engine as 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.
•Saw Head Lifting Cables — Regularly before, during, and after operations; inspect the cables for
any wear or kinks. Ensure that the cables are in perfect condition. Oil coiled part of cable often to
prevent premature wear. Replace with new cables as necessary.

SAWMILL ASSEMBLY
1. UNPACKING
Unpack the contents of the crate except for the sawmill head and the two long boxes in the bottom
that contain the two sections of track. Unbolt the front of the crate and lay 6” (150mm) high support
blocks in front of the crate. Bend the front of the crate down. Carefully lay the sawmill head and the
cardboard down onto the 6” (150mm) support blocks. Slide the sawmill head out of the crate as
shown below.


2. TRACKS
Assemble the track system with the provided nuts & bolts. It is important to assemble and level the
track on a firm foundation before tightening all of the nuts and bolts. It is ideal to assemble the tracks
on a solid and level footing that is a minimum of 4” (100mm) off of the ground. This will allow for easy
cleanup of sawdust from under the tracks and height adjustment of the log supports.
The width of the track should be assembled so that it is 26.0” (660mm) wide when measuring the
width from the outside to outside of the “L” rails.
Page of 10 49


The pictures below show the assembly of the log bunks to the “L” rails. Ensure that the two end
bunks are square (90 degrees) to the track ‘L’ rails.
Assemble carriage stops at the ends of the tracks (4 stops total) and tighten bolts as shown below.
