Ensure correct chain tension. Ensure the
chain is sharpened correctly.
■ Never work with a loose, widely stretched
or heavily worn chain.
■ Always use a low kickback chain.
■ Only replace the guide bar and saw chain
with the identical parts as specified in the
Product Specifications of this manual.
■ Do not let the nose of the guide bar contact
a log, branch, or any other obstruction which
could be hit while you are operating the
product.
■ Never work with the tip of the guide bar.
■ Use spiked bumper to secure the product
onto the limb being sawed.
■ Saw with the guide bar at a flat angle.
■ Only cut with the motor at high speeds.
Pruning Operation:
■ Always hold the product firmly with both
hands on auxiliary handle and main handle.
Never operate this product using only one
hand. (Fig. 19)
■ Maintain a firm grip with your thumbs and
fingers encircling the handles. A firm grip
will help you reduce 'kickback' and maintain
control of the product.
■ Always hold the product at an angle of
not more than 60° from the horizontal level.
Otherwise safe operation is not possible.
(Fig. 20)
■ Never stand directly under the limb you
are sawing. Objects may fall different than
expected. There is risk of being struck by
falling branches or by those that rebound
after hitting the ground. Always position
yourself out of the path of falling limbs.
(Fig. 21)
■ Keep other persons away from cutting end
of product and at a safe distance from the
work area. Maintain a minimum distance of
50 ft to bystanders. (Fig. 22)
OPERATION
WARNING!
prune! Do not stand on ladders, platforms,
logs, or in any position which may cause you
to lose your balance or control of the product!
When pruning trees, it is important not to
make the flush cut next to main limb or trunk
until you have cut off the limb further out to
reduce the weight! This prevents stripping the
bark from the main member.
■ Never stand on a ladder or other type of
unstable support while using the product.
Insecure stand invites hazards. (Fig. 23)
WARNING!
designed to provide protection from electric
shock in the event of contact with overhead
electric lines! Therefore do not use product
near cable, electric power or telephone
lines. Keep a minimum distance of 50 ft to all
electric lines! (Fig. 24)
■ Use the product only with secure footing.
Regularly change the working position and
include rest periods during operation.
■ Do not operate the product with arms fully
extended or attempt to cut areas which are
difficult to reach.
■ Keep a firm, steady pressure on the
product while working with it. Do not try to
force the product through the wood; let the
gripping action of the saw chain teeth do the
work, allowing you to apply minimal leverage
pressure.
■ Beware when reaching the end of the
cut. The weight of the product may change
unexpectedly as it cuts free from the wood.
Accidents can occur to the legs and feet.
Always remove the product from a wood cut
while it is running.
NOTE: The chain must be running at full
speed before it comes into contact with the
wood.
