Guide Bar
Generally, guide bars with small radius tips have
somewhat lower potential for kick-back. You should use a
guide bar and matching chain which is just long enough
for the job. Longer bars increase the risk of loss of control
during sawing. Regularly check the chain tension. When
cutting smaller branches (less than the full length of the
guide bar) the chain is more likely to be thrown off if the
tension is not correct.
Working Instructions
Understanding the forces within the wood
When you understand the directional pressures and
stresses inside the wood you can reduce the "pinches" or
at least expect them during your cutting. Tension in the
wood means the fibers are being pulled apart and if you
cut in this area, the "kerf" or cut will tend to open as the
saw goes through. If a log is being supported on a saw
horse and the end is hanging unsupported over the end,
tension is created on the upper surface due to the weight
of the overhanging log stretching the fibers. Likewise,
the underside of the log will be in compression and the
fibers are being pushed together. If a cut is made in this
area, the kerf will have the tendency to close up during
the cut. This would pinch the blade.
Limbing a tree
Limbing is removing the branches from a fallen tree.
When limbing, leave larger lower limbs to support the
log off the ground. Remove the small limbs in one cut.
Branches under tension should be cut from the bottom
up to avoid bindingthe chain saw.
Cutting springpoles
A springpole is any log, branch, rooted stump, or sapling
which is bent under tension by other wood so that it
springs back if the wood holding it is cut or removed.
Warning! Springpoles are dangerous and could strike
the operator, causing the operator to lose control
of the chain saw. This could result in severe or fatal
injury to the operator. This should be done by trained
users.
Residual Risk
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual
risk factors. The following hazards may arise in use and
the operator should pay special attention to avoid the
following:
• Injury caused by vibration
Always use the right tool for the job. Use designated
handles. Restrict working time and exposure.
• Damage to hearing due to exposure to noise
Wear hearing protection and limit exposure.
• Injury caused by contact with exposed saw teeth of
the chain
• Injury caused by thrown-out pieces of the workpiece
(wood chips, splinters)
• Injury caused by dust and particles
• Injury to the skin caused by contact with lubricants
32
• Parts ejected from the saw chain (cutting/injection
hazards)
• Unforeseen, abrupt movement, or kickback of the
guide bar (cutting hazards)"
Risk Reduction
It has been reported that vibrations from handheld
tools may contribute to a condition called Raynaud's
Syndrome in certain individuals. Symptoms may include
tingling, numbness, and blanching of the fingers, usually
apparent upon exposure to cold. Hereditary factors,
exposure to cold and dampness, diet, smoking and work
practices are all thought to contribute to the develop-
ment of these symptoms. There are measures that can
be taken by the operator to possibly reduce the effects
of vibration:
• Keep your body warm in cold weather. When
operating the unit wear gloves to keep the hands and
wrists warm.
• After each period of operation, exercise to increase
blood circulation.
• Take frequent work breaks. Limit the amount of expo-
sure per day.
• Protective gloves available from professional chain
saw retailers are designed specifically for chain saw
use which give protection, good grip and also reduce
the effect of handle vibration. These gloves should
comply with EN 381-7 and must be CE marked.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor.
Warning! Injuries may be caused, or aggravated, by
prolonged use of a tool. When using any tool for
prolonged periods, ensure you take regular breaks.
Specified Conditions of Use
The minke chain saw is to be used as a branch saw.
The cordless pruning saw is only intended for use
outdoors.
For safety reasons, the pruning saw must be adequately
controlled by using two-handed operation at all times.
The pruning saw is designed for cutting branches, trunks,
logs, and beams of a diameter determined by the cutting
length of the guide bar. It is only designed to cut wood. It
is only to be used by adults who have received adequate
training on the hazards and preventative measures/
actions to be taken while using the pruning saw.
Do not use the pruning saw for any purpose not listed
in the specified conditions of use. It is not to be used for
professional tree services. The pruning saw is not to be
used by children or by persons not wearing adequate
personal protective equipment and clothing.
Warning! When using the pruning saw, the safety
rules must be followed. For your own safety and that of
bystanders, you must read and fully understand these
instructions before operating the pruning saw. You
