WARNING:
If desired depth of cut is greater
than can be safely cut in one pass, make cuts in
two or three passes.
DIRECTION
OF FEED AND THRUST
See Figures 7 and 8.
The trimmer motor and cutter revolve in a clockwise
direction.
This gives the tool a slight tendency to twist
(in your hands) in a counterclockwise
direction,
especially when the motor starts.

Because of the extremely high speed of cutter rotation
during a "proper feeding" operation, there is very little
kickback to contend with under normal conditions.
However, should the cutter strike a knot, hard grain,
foreign object, etc. that would affect the normal
progress of the cutting action, there will be a slight
kickback -- sufficient to spoil the trueness of your cut if
you are not prepared.
Such a kickback is always in
the direction opposite to the direction of cutter rotation.
To guard against such a kickback, plan your set-up
and direction of feed so that you will always be
thrusting the tool -- to hold it against whatever you are
using to guide the cut -- in the same direction that the
leading edge of the cutter is moving.
In short, the
thrust should be in a direction that keeps the sharp
edges of the cutter continuously biting straight into
new (uncut) wood.
EXTENSION
CORDS
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
tool overheating, use an extension cord that is heavy
enough to carry the current the tool will draw.
A wire gage size (A.W.G.) of at least 16 is
recommended for an extension cord 100 feet or less in
length. When working outdoors, use an extension cord
that is suitable for outdoor use. The cord's jacket will
be marked WA.
A
CAUTION:
Keep extension cords away from
trimming area and position the cord so that it wilt
not get caught on lumber, tools, etc., during
trimming operation.
A
WARNING:
Check extension cords before each
use. If damaged replace immediately.
Never use
tool with a damaged cord since touching the
damaged area could cause electrical shock
resulting in serious injury.
HELPFUL
HINTS
t/
Always clamp workpiece securely before
trimming.
t/
A safe operator is one who thinks ahead.

t/
Study all safety rules and do the job safely.
t/
NEVER place your hands in jeopardy.
t/
Make certain clamps can't loosen while in
