Use extreme
caution
when cutting
small-sized
brush
and
saplings,
as slender
material may catch the saw chain and be
whipped
toward
the operator
or pull the operator
off balance.
This saw is classified
by UL as a Class 1C saw in accordance
with CSA Z62.1-03.
It is intended
for infrequent
use by
homeowners,
cottagers
and campers,
and for general
applications
such as clearing,
pruning,
cutting
firewood,
etc. It is
not intended
for prolonged
use. If the intended
use involves
prolonged
periods of operation,
this may cause circulatory
problems
in the user's hands
due to vibration.
Do not operate
the unit in a tree or on a ladder unless
specifically
trained to do so.
Never remove,
modify
or make inoperative
any safety device
furnished
with the unit.
Do not use the unit in the presence of flammable
liquids or gases.
Do not attempt
operations
beyond the operator's
capacity
or
experience.
Do not operate
a unit that is damaged,
improperly
adjusted
or
not completely
and securely
assembled.
Make sure moving
parts stop when
the unit is turned
off. Do not use the unit if it
does not turn on and off properly.
Have defective
parts replaced
by a Sears or other qualified
service dealer.

KICKBACK
SAFETY
WARNING:
Kickback
may occur when the
nose or tip of the guide bar touches
an object,
or when the
wood
closes in and pinches the saw chain in the cut. In
some cases, tip contact
may cause a lightening-fast
reverse action,
kicking the guide bar rapidly back towards
the operator.
Pinching the saw chain
along the top of the
guide bar may push the guide bar rapidly back towards
the
operator.
Either of these reactions
may cause a loss of
control
over the saw, which could result in serious injury to
the user. Contact
with foreign objects within the wood
can
also induce a loss of chain saw control.
Understanding
Kickback
A basic understanding
of kickback
can help reduce or
eliminate
the
element
of surprise
and the chance
of kickback-related
injury.
Sudden
surprise
contributes
to accidents.
Rotational
Kickback
can happen when the upper tip of the
guide bar contacts
an object while the chain
is moving
(Fig. A).
This can cause the chain to dig into the object and momentarily
stop
moving.
The guide bar is then kicked up and back toward
the operator
in a lightning-fast
reverse reaction.
Linear Kickback
can happen when the wood on
either
side of a
cut closes in and pinches the moving saw chain along the top of
the guide bar (Fig. B). This can cause the chain to instantly
stop.
The chain force is then reversed,
causing the saw to move in the
opposite
direction,
sending
the saw straight
back toward
the
operator.
Pull-In
can happen when the moving
chain on the bottom
of the
guide bar hits a foreign object
inside the wood. This can cause
the chain to suddenly
stop. The saw is then pulled forward
and
away from the operator,
which could
potentially
result in the loss
of control
of the saw.

Safety
Precautions
Take the following
steps to reduce the chance
of accident
or injury:
Do not rely
exclusively
upon the safety devices
built
into
the unit.
Do not cut above shoulder
height.
Do not overreach.
Always keep proper footing
and balance. Take
extra
care when working
on steep slopes
or
inclines.
Do not make cuts with the tip of the guide bar.
Make sure the area of operation
is free from obstructions.
Do not
let the tip of the guide
bar contact
any object, such as a log,
branch,
the ground
or other obstruction.
Always
inspect the wood
before cutting.
Foreign objects
could
damage
the unit or cause serious
personal
injury. Never cut
through
nails, metal rods, railroad ties or pallets.
Do not operate
the unit with one hand! Serious
injury to the
operator,
helpers or bystanders
may result from one-handed
operation.
This unit is intended
for two-handed
use. Always grip
the unit firmly with
both hands when the unit is running.
Hold the
front handle with the left hand and the rear handle with the right
hand. Firmly
encircle
the handles with
the thumbs
and fingers.
Do not let go. A firm grip will help maintain
control
of the unit
and reduce the chance
of kickback.
Stand slightly to the left of the unit to avoid being
in
the direct
line of the saw chain.
Never start the saw when the guide bar
is
inside an
existing
cut.
Be
extremely
careful when
re-entering
a cut.
Always
begin a cut with the unit running
at full speed.
Fully
squeeze the throttle
control
and maintain
a steady cutting
speed.
Slower speeds
increase
the chance
of kickback.
Keep the saw housing
pressed firmly
against the wood.
Do not cut more than one log or branch at a time.
Do not twist
the unit when
removing
the guide
bar from a cut.
Watch out for shifting
objects
(logs, branches,
etc.)
that might
pinch
or fall onto the saw chain during operation.
