OPERATION
DIRECTION OF FEED AND THRUST
See Figures 8 and 9.
TRIMMER FEED
DIRECTION
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 markedWA.
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.
