• Do not operate this product in a tree.
Operation of the product while up in a tree
may result in personal injury.
• The chain brake must be engaged when
the product is started to decrease the risk
that the saw chain touches you during start.
• Avoid kickback, skating, bouncing and
dropping, which can result in serious injury.
• Obey all safety rules to help avoid kickback
and other forces which can result in serious
injury.
• Adjust the saw chain tension regularly to
make sure that the saw chain does not
slack. A slack saw chain may jump off and
cause serious injury or death.
• Do not fell trees using an incorrect
procedure. This can cause injury to
persons, hit a utility line or cause damage
to property.
• The operator should remain on the uphill
side of the terrain as the tree is likely to roll
or slide downhill after it is felled.
6653 - 006 - 10.02.2020

• Plan and clear an escape path before cuts
are started. The escape path should extend
back and diagonally to the rear of the
expected line of fall.
• Always stop the engine before you move
the product between the trees.
• Make sure you firmly plant your feet on the
ground and distribute your weight evenly.
• Always keep proper footing and operate
the product only when standing on fixed,
secure and level surface. Slippery or
unstable surfaces such as ladders may
cause a loss of balance or control.
Kickbacks, skating, bouncing and dropping
Different forces can have an effect on the safe
control of the product.
•Skating is when the guide bar glides or
moves quickly across the wood.
•Bouncing is when the guide bar lifts off the
wood and touches it again and again.
•Dropping is when the product drops down
after the cut is made. This can cause the
moving chain to touch a part of the body or
other objects, causing injury or damage.
•Kickback is when the end of the guide bar
touches objects and moves rearward, up or
suddenly forward. Kickback also occurs
when the wood closes in and pinches the
saw chain during the cut. Loss of control
can result if the product touches an object
in wood.
•Rotational Kickback can occur when the
moving chain touches an object at the
653 - 006 - 10.02.2020 7

top of the guide bar. This can cause the
chain to bury into the object and cause
the chain to stop immediately. The result
is a very fast, reverse reaction that
moves the guide bar up and rearward in
the direction of the operator.
•Pinch-Kickback can occur when the saw
chain suddenly stops during the cut. The
wood closes in and pinches the moving
saw chain along the top of the guide
bar. The sudden stop of the chain
reverses the chain force and causes the
product to move in the opposite
direction of the turn of the chain. The
product moves rearward in the direction
of the operator.
•Pull-In can occur when the saw chain
suddenly stops when the moving chain
touches an object in the wood along the
bottom of the guide bar. The sudden
stop pulls the product forward and away
from the operator, which can easily
cause the loss of control of the product
by the operator.
Make sure that you understand the different
forces and how to prevent them before you
operate the product.
To prevent kickbacks, skating, bouncing and
dropping
• While the engine runs, make sure to hold
the product tightly. Keep your right hand on
the rear handle and the left hand on the
front handle. Tightly hold with thumbs and
fingers around the handles. Do not let go.
8653 - 006 - 10.02.2020

• Keep control of the product during the cut
and after the wood falls to the ground. Do
not let the weight of the product drop down
after the cut is made.
• Make sure that the area in which you are
cutting is free from blockage. Do not let the
nose of the guide bar touch a log, branch
or other blockages while you operate the
product.
• Cut at high engine speeds.
• Do not overreach or cut above shoulder
height.
• Obey the manufacturer's sharpening and
maintenance instructions for the saw chain.
• Only use replacement guide bars and saw
chains specified by the manufacturer.
• The risk of kickback is increased if the
depth gauge setting is too large.
Personal protective equipment
• Always use the correct personal protective
equipment when you operate the product.
The personal protective equipment does
not erase the risk of injury. The personal
protective equipment decreases the grade
of injury if an accident occurs.
• Generally, clothes should be close-fitting
without restricting your freedom of
movement.
• Use an approved protective helmet.
• Always use approved ear protection while
you operate the product. Noise for a long
period can cause hearing loss.
• Use protective glasses or a face visor to
reduce the risk of injury from thrown
objects. The product is capable of throwing
objects, such as wood chips, small pieces
of wood, etc., at great force. This can result
in serious injury, especially to the eyes.
• Use gloves with chainsaw protection.
• Use trousers with chainsaw protection.
• Use boots with chainsaw protection, steel
toe-cap and non-slip sole.

guide bar and saw chain or other sources.
Always have fire extinguishing tools and a
shovel available to help prevent forest fires.
