OPERATION
Hold the fiberglass tube extension in one hand and the handle in the other hand.
After positioning the saw in the cutting area, move the trigger safety latch to a forward
position, allowing the trigger to be depressed.
Depress the trigger slowly and allow the blade to start rotating.
When at full speed, feed the saw into the material with constant pressure.
Twisting, jamming or forcing the saw while cutting can cause problems such as kickback,
jamming, pulling, or stalling within the cut. This can cause failure and damage to the saw,
and/or seriously injure the operator.
Allow the blade to feed steadily and quickly through the work while applying a pressure
against the cut. NOTE: A slow cut will create excessive heat reducing the life of the blade
When the cut is completed, release the trigger and the saw will stop rotating.
There are a number of safety items that need to be addressed when a novice is using
the tool for the first time. Seek out the supervisor for basic instruction in handling the
tool. Some basic problems are easily overcome by knowing the rules of operation.
Kickback was described earlier in this manual (see page 5). Read again.
Kickback occurs when the blade bumpsor jams the wood. bumping or jamming
the blade will kick the saw up and back toward the operator at lightning speed.
Unintensionally touching the wood with the top side may push the saw out of the
operator’s hands. Both situations can cause serious injury and/or damage to the
operator, nearby persons, and surrounding equipment.
Always be aware of the material being cut. Such things as nails and other hard objects
cancause kickback, flying debris, bladedamage,and/or serious personal injury ordeath.
DO NOT use this saw for cutting or clearing at ground level. If the blade contacts the
ground or other solid object, the operator may lose control of the saw, the blade may
shatter, or flying debris may cause injury to the operator and/or nearby personnel.
Always run the saw at full speed when cutting.
Always stand to the side of the cutting path of the blade.
Never be off balance or overreach while cutting.
Always wear and use proper safety equipment such as hand and eye protection.
Always keep the area clear of obstructions and be aware of potential hazards.
Keep all non-esential personnel out of the danger zone.
Always be alert to shifting or falling tree limbs. Binding and pinching of the blade
may occur and cause difficulty in handling.
To store the saw between operations, find a clear, flat space and lay the saw down.
If the saw is out of use for a period of time, shut off the hydraulic power source
to prevent unnecessary heat and wear to the saw and hoses.
