Depth Of Cut - Craftsman 315.277150 Operator's Manual

DEPTH OF CUT
See Figure 9.
Depth of cut affects the rate of feed and the qual}ty of a
cut. Using the proper depth of cut can lessen the possibil-
ity of damage to the trimmer motor and cutter.
A deep cut requires a s!ower feed than a shallow one. A
cut that is too deep wil! slow the feed so that the cutter is
scraping, rather than cutting.
A too-deep cut can cause smaller cutters to be broken
off. Cutters that are 1/16 in. (1.6 mm)in diameter are eas-
ily broken off when subjected to too much side thrust. A
larger cutter is not as likely to break, but attempting a cut
that is too deep may result in a rough cut, and may make
it difficult to guide and control the cutter as desired.
it is recommended that you do not exceed 1/8 in. (3.2 mm)
depth of cut in a single pass, regardless of the cutter size
or the softness or condition of the workpiece. This will
result in a higher quality cut.
To make deeper cuts, it is necessary to make as many
successive passes as required, lowering the cutter
1/8 in. (3.2 mm) for each new pass. To save time, perform
a!l the cutting necessary at one depth setting, then lower
the cutter for the next pass. This wil! assure uniform depth
when the final pass is completed.
NOTE: if desired depth of cut is greater than can be safely
cut in one pass, make cuts in two or three passes.
_ WARNING:
if the desired depth of cut is greater
than can be safely cut in one pass, make cuts in two
or more passes. Do not remove more than 1/8" in
a single pass. Excessive depth of cut can result in
loss of control and the possibility of serious personal
injury.
