DEPTH OF CUT ADJUSTMENT

The depth of cut on your planer is controlled by raising

or lowering the head assembly (A) Fig. 22, which

contains the cutterhead and feed rollers. The head

assembly (A) moves on four precision ground steel

columns, three of which are shown at (B). To adjust for

depth of cut, simply loosen the two head assembly lock

knobs, one of which is shown at (C), and turn the head

raising and lowering handwheel (D). Turning the

handwheel (D) clockwise, raises the head assembly and

counterclockwise, lowers the head assembly. Then

tighten the two head assembly lock knobs (C).

The maximum depth of cut when planing stock narrower

than 6 inches wide is 3/16" when the stock is run

through the planer on one side or the other of the

cutterhead. A limiter (E) Fig. 22, is provided to limit the

depth of cut to 1/8" on stock wider than 6 inches.

FEED SPEED CONTROL

CHANGE SPEEDS ONLY WHILE THE

MOTOR IS RUNNING. DO NOT CHANGE SPEEDS

WHILE PLANING.

Two feed roll speeds of 16 and 30 feet per minute are

provided with your planer. Generally speaking, the

slower feed rate provides more cuts per inch, thus a

finer, smoother finish of the workpiece is obtained. A

good rule to follow would be to operate the machine at

the faster feed rate for general planing and switch to the

slower feed rate for the final finished dimension of the

workpiece. When planing wide stock (wider than 8")

particularly in hard wood, the slower feed speed is more

desirable as there is less strain on the motor and a better

finish is obtained since there are more cuts per inch of

stock length.

When the shifter knob (A) Fig. 24, is pushed all the way

in as shown, the feed speed will be 30 feet per minute.

Fig. 25 Fig. 26

When the shifter knob (A) Fig. 25, is pulled all the way

out as shown, the feed speed will be 16 feet per minute.

When the shifter knob (A) Fig. 26, is in the center

(neutral) position as shown, the machine will stop

feeding.
