Operating The Trimmer - Ryobi P600 Operator's Manual

OPERATiNG THE TRiMMER

Before starting the trimmer, with the battery pack discon-
nected, make sure the bit is securely tightened in the collet
and that the depth of cut is properly set. Never start the
trimmer while the bit is in contact with the workpiece.
After completing a cut, pull the bit slightly away from the cut
surface. Turn the trimmer off and wait for the rotating bit to
completely stop before completely removing the tool from
the work surface.
When cutting, locate the base of the trimmer over the work
surface and firmly hold the body of the trimmer with your
hand. Make sure the trimmer is running at full speed before
contacting the workpiece.

See Figures 8 - 9.
The trimmer motor and bit 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.
Feed the trimmer into the workpiece from left to right. When
fed from left to right, the rotation of the bit pulls the trim-
mer against the workpiece. If fed in the opposite direction,
the rotation forces of the spinning bit will tend to throw the
trimmer away from the workpiece, causing kickback. This
could result in loss of control of the trimmer.
Because of the extremely high speed of bit rotation during
a proper feeding operation, there is very little kickback to
contend with under normal conditions. However, should the
bit strike a knot, hard grain, foreign object, etc. that would
affect the normal progress of the cutting action, there will
be a slight kickback. Kickback could be sufficient to spoil
the trueness of your cut if you are not prepared. Such a
kickback is always in the direction opposite the direction
of bit rotation.
To guard against 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 bit is moving. The thrust
should be in a direction that keeps the sharp edges of the
bit continuously biting straight into new (uncut) wood.
