PROPER CUTTING STANCE
See Figure 12, page iv
■ Balance your weight with both feet on solid
ground.
■ Keep left arm with elbow locked in a "straight
arm" position to withstand any kickback force.
■ Keep your body to the left of the chain line.
■ Keep your thumb on underside of handle
bar.
BASIC OPERATING/CUTTING
PROCEDURES
■ Practice cutting a few small logs using the
following technique to get the "feel" of using
the saw before you begin a major sawing
operation.
■ Take the proper stance in front of the wood
with the saw idling.
■ Press the safety switch and squeeze the
trigger switch, then release safety switch and
let the chain accelerate to full speed before
entering the cut.
■ Begin cutting with the saw against the log.
■ Keep the unit running the entire time you
are cutting, maintain a steady speed.
■ Allow the chain to cut for you; exert only
light downward pressure.
■ Forcing the cut could result in damage to
the bar, chain, or motor.
■ Release the trigger switch as soon as the
cut is completed, allowing the chain to stop.
If you run the saw without a cutting load,
unnecessary wear can occur to the chain,
bar, and unit.
■ Do not put pressure on the saw at the end
of the cut.
WORK AREA PRECAUTIONS
See Figure 13, page v
■ Cut only wood or materials made from
wood; no sheet metal, no plastics, no
masonry, no non-wooden building materials.
■ Never allow children to operate the saw.
Allow no person to use this chainsaw who
has not read this OPERATOR'S MANUAL or
received adequate instructions for the safe
and proper use of this chainsaw.
OPERATION
■ Keep everyone - helpers, bystanders,
children, and animals - a SAFE DISTANCE
from the cutting area. During felling
operations, the safe distance should be at
least twice the height of the largest trees in
the felling area. During bucking operations,
keep a minimum distance of 15 ft. (4.6 m)
between workers.
■ Always cut with both feet on solid ground to
prevent being pulled off balance.
■ Do not cut above chest height, because a
saw held higher is difficult to control against
kickback forces.
■ Do not fell trees near electrical wires
or buildings. Leave this operation for
professionals.
■ Cut only when visibility and light are
adequate for you to see clearly.
HAZARDOUS CONDITIONS IN TREE
FELLING
See Figures 14a-14b, page v
When felling a tree, it is important that you
heed the following instructions and warnings
to prevent possible serious injury:
TO AVOID KICKBACK
■ Saw with guide bar at a flat angle.
■ Never work with a loose, widely stretched
or the heavily worn out chain.
■ Ensure chain is sharpened correctly.
■ Never saw with the tip of the guide bar.
■ Always hold the product firmly with both
hands.
■ Always use a low kickback chain.
■ Ensure correct chain tension.
■ Only cut with the motor at high speeds.
■ 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.
■ Follow the chain sharpening and
maintenance instructions in the CARE AND
MAINTENANCE section of this manual.
■ Only replace the guide bar and saw chain
with the identical parts as specified in the
Parts List of this manual.
