OPERATION

DEPTH OF CUT

See Figures 16 - 17.

Depth of cut is important because it affects the rate of feed

that, in turn, affects the quality of the cut and the possibility

of damage to the tool’s motor and bit.

A deep cut requires a slower feed than a shallow one. A cut

that is too deep will slow the feed so that the bit is scraping

rather than cutting. A too deep cut can cause smaller bits

to be broken off. Bits that are 1/16 in. in diameter are easily

broken off when subjected to too much side thrust. A large

enough bit is not likely to break, but attempting a cut that

is too deep may result in a rough cut, and it may be difficult

to guide and control the bit as desired. It is recommended

that you do not exceed 1/8 in. depth of cut in a single pass,

regardless of the bit size or the softness or condition of the

workpiece.

To make deeper cuts, make as many successive passes as

needed, lowering the bit 1/8 in. for each new pass. To save

time, perform all the cutting necessary at one depth setting

before lowering the bit for the next pass. This will insure a

uniform depth when you complete the final pass.

NOTE: Do not remove more than 1/8 in. in a single pass.

Excessive depth of cut can result in loss of control and the

possibility of serious personal injury.

ADJUSTMENTS

ADJUSTING LOCK LEVER TENSION

See Figure 18.

Over time and with repeated use, the lock lever may

become loose. When this occurs, tighten the stop nut

slightly. The elastic stop nut should be loose enough so

that there is some play in the lock lever when it is in

the open position.

NOTE: Do not over tighten the elastic stop nut. The lock lever

should clamp tightly to secure the motor housing.

CAUTION:

Make sure the motor housing does not move up or down

when clamped. If motor is not securely clamped in base,

adjustments will not be accurate.
