OPERATION

OPERATIONAL CONTROLS AND ADJUSTMENTS

Make sure that the switch is in the "OFF" position before plugging the cord in the outlet. Do not

touch the metal prongs of the plug when unplugging or plugging 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.

STARTING AND STOPPING THE GRINDER

IMPORTANT: When the machine is not in use, lock the switch in the "OFF" position to prevent unauthorized use.

To lock the machine, grasp the switch toggle (B) 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.
