TO START AND STOP MOTORS
CAUTION: Before connecting to power source ALWAYS MAKE
SURE THE SWITCH IS IN THE "OFF" POSITION and that the power
circuit is the same as that specified on the specification plate of the
machine.
1. Connect the machine power cord to the power source.
CAUTION: Make sure hands, workpiece, and all foreign objects are
clear of the cutter area.
2. Move switch (A) Fig. 16, to ON position to start motors.
3. Move switch to OFF position to stop motors.
TO LOCK SWITCH
The switch button acts as a key. It may be removed to lock the switch in the
OFF position:
CAUTION: Disconnect machine from power circuit to prevent
accidental start-up while removing switch button.
1. Place switch in the OFF position.
2. Pull the button from the switch (see Fig. 17).
3. Make sure switch is in OFF position. (If the switch has moved to the On
position: it can be returned to the OFF position without re-installing the
button).
TO ADJUST WORK CLAMP
The work clamp must be adjusted to securely hold the workpiece in the
machine. Variations in thickness of work may make it necessary to re-adjust
the clamp. The clamp should "snap" closed and hold the workpiece
securely. If the clamp will not close: then it must be loosened. If the clamp
closes too easily (does not hold work securely), it must be tightened.
IMPORTANT: When using thin material (between
a shim is required. Make the shim from
or hardboard). The shim should be approximately the same size as
the table top. Firmly clamp the shim to the top of the table (see Fig.
18). Place the thin workpiece on top of the shim, clamp in place with
the work clamp, and make pocket cut in normal fashion (a slot will
be cut through the shim).
