5.2- Working with the chainsaw
WARNING
- Before proceeding to your job, read the section "Safety".
It is recommended to first practice sawing easy logs. This also helps you get
accustomed to your machine.
- Always follow the safety regulations. The chain saw must only be used for
cutting wood.
It is forbidden to cut other types of material. Vibrations and kickback vary with
different materials and the requirements of the safety regulations would not be
respected. Do not use the chain saw as a lever for lifting, moving or splitting
objects. Do not lock it over fixed stands. It is forbidden to hitch tools or
applications to the PTO (driveshaft) other than those specified by the
manufacturer.
- It is not necessary to force the saw into the cut. Apply only light pressure
while running the engine at full throttle.
- When the saw chain is caught in the cut, do not attempt to pull it out by force,
but use a wedge or a lever to open the way.
- This saw is equipped with a chain brake that will stop the chain in the event of
kickback if operating properly. You must check the chain brake operation
before each usage by running the saw at full throttle for 1-2 seconds and
pushing the front hand guard forward. The chain should stop immediately with
the engine at full speed. If the chain is slow to stop or does not stop, replace the
brake band and clutch drum before use.
- It is extremely important that the chain brake be checked for proper operation
before each use and that the chain be sharp in order to maintain the kickback
safety level of this saw. Removal of the safety devices, inadequate
maintenance, or incorrect replacement of the bar or chain may increase the risk
of serious personal injury due to kickback.
Spiked bumper (a): Device (toothed stop for holding saw steady against
wood), fitted in front of the guide bar mounting point, acting as a pivot when in
contact with a tree or log.
Installation of spiked bumper: The Spiked bumper belongs to the chain saw.
It must be screwed up on chain saw before the initial use.
Fix the spiked bumper with two screws on the front of the chain saw body.
Use of spiked bumper: The Spiked bumper must always be put on while using
the chain saw on tree trunk.
Push the spiked bumper into the tree trunk by using the rear handle. Push the
front handle in the direction of cutting line.
The spiked bumper must be remaining set for further saw guiding if necessary.
Pull-in effect frequently occurs when the bumper spike of the saw is not held
securely against the tree or limb and when the chain is not rotating at full speed
before it contacts the wood.
To avoid pull-in effect, always start a cut with the chain rotating at full speed
and the bumper spike in contact with the wood
Use the spiked bumper to support the chainsaw on the wood. During sawing,
you can use the spiked bumper as a lever.
ATTENTION! National or local regulations may restrict the use of the
machine to certain hours or periods. Check with your local authority.
