OPERATION
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 | TRIM GRAINS | |
completely stop before completely removing the tool from | ||
the work surface. | ||
| ||
When cutting, locate the base of the trimmer over the work | END FIRST | |
hand. Make sure the trimmer is running at full speed before | ||
surface and firmly hold the body of the trimmer with your |
| |
contacting the workpiece. |
| |
DIRECTION OF FEED AND THRUST |
| |
See Figures 7 - 8. |
| |
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 |
| |
feed so that you will always be thrusting the |
| |
against whatever you are using to guide the |
| |
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. |
