OPERATIONAL Controls and ADJUSTMENTS

STARTING AND STOPPING THE GRINDER

Make sure that the switch is in the "OFF" position before plugging cord into outlet. Do not touch the plug’s metal prongs when unplugging or plugging in the cord.

The on/off switch (A) Fig. 8 is located on the front of the grinder. To turn the machine "ON", move the switch up to the "ON" position. To turn the machine "OFF", move the switch (A) down to the "OFF" position.

LOCKING SWITCH IN THE "OFF" POSITION

IMPORTANT: When the machine is not in use, the switch should be locked in the "OFF" position to prevent unauthorized use. To lock the machine, grasp the switch toggle (A) and pull it out of the switch (Fig. 8). With the switch toggle (A) removed, the switch will not operate. However, should the switch toggle be removed while the grinder is running, the machine can be turned "OFF," but cannot be restarted without re-inserting the switch toggle (A).

In the event of a power outage (such as a breaker or fuse trip), always move the switch to the "OFF" position until the main power is restored.

VARIABLE SPEED CONTROL

The grinder is equipped with a variable speed control

(B)Fig. 8. When the variable speed control knob is positioned at the far left position (counter clockwise), the RPM is 1725. The rotation increases when the variable speed control knob is turned clockwise. Positioned far right, the RPM is 3450.

FLEXIBLE LAMP

The flexible lamp oper­ates­ inde­pen­dent­ly­ of the grinder. To turn the lamp on and off, rotate the switch (A) Fig. 10.

To reduce the risk of fire, use 40 watt or smaller, 120 volt, reflector track type light bulb (not supplied). A standard­ household­ light bulb should not be used. The reflector track type light bulb should not extend below the lamp shade.
