DIRECTION OF FEED AND THRUST
See Figures 8 and 9.
The trimmer motor and cutter revolve in a clockwise direc-
tion. 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 setup 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.
CAUTION:
Keep extension cords away from any trimming area and
position the cord so that it will not get caught on lumber,
tools, etc., during trimming operation.
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.
