INSTALLiNG/REMOVING BITS
See Figures 2 - 3.
If installing the bit for the first time, it can be installed once
the collet nut is loose. If changing bits, the bit will easily slip
from the collet after loosening the collet nut.
[] Turn the switch to OFF and remove the battery pack
from the trimmer.
[] Place the trimmer upside down on a workbench.
[] To remove the subbase assembly, open the depth
adjustment latch. Slide the base upward, then left, then
upward again to remove the base.
[] Depress the spindle lock button.
[] Use the wrench provided to turn the collet nut in a
counterclockwise direction. Continue to depress the
spindle lock button while loosening the collet nut.
[] With the tool still upside down on a workbench, insert
the shank of the bit into the collet. The shank of the bit
should be close to but not touching the bottom of the
collet. This allows for expansion when the bit gets hot.
A clearance of 1/16 in. is adequate.
NOTE: The collet is machined to precision tolerances to fit
bits with 1/4 in. diameter shanks.
[]
Hand-tighten the collet nut. Then, depress the spindle
lock button and continue tightening the collet nut with
the wrench provided by turning it in a clockwise direc-
tion.
_ WARNING: If the collet nut is not tightened secure-
ly, the bit may come out during use, causing serious
personal injury.
[] Replace the subbase assembly by sliding it onto the
tool, along the grooves on the sides of the tool.
NOTE: Replace the base before using the tool. Do not
attempt to operate the tool without the base installed.
[] Close the depth adjustment latch.
[] Replace the battery pack.
,_ WARNING: If you are changing a bit immediately
after use, be careful not to touch the collet nut, bit,
or collet with your hands or fingers. They will get
burned because of the heat buildup from cutting.
Always use the wrench provided.
