OPERATION

OPERATING CONTROLS AND ADJUSTMENTS

FASTENING MACHINE TO SUPPORTING SURFACE

Before operating your miter saw, firmly mount it to a workbench or other supporting surface. Four holes (A) Fig. 12 are provided for fastening the saw to a supporting surface.

When frequently moving the saw from place to place, mount the saw on a 3/4” piece of plywood. The saw can then be easily moved from place to place and the plywood can be clamped to the supporting surface using “C” clamps.

STARTING AND STOPPING MACHINE

To start the machine, depress the switch trigger (A) Fig. 13. To stop the machine, release the switch trigger.

This saw is equipped with an automatic electric blade brake. As soon as the switch trigger (A) Fig. 13 is released, the electric brake is activated and stops the blade in seconds.

A rotating saw blade can be dangerous. After completing the cut, release the switch trigger (A) Fig. 13 to activate the blade brake. Keep the cuttinghead down until the blade has come to a complete stop.

The torque developed during braking may loosen the arbor screw. The arbor screw should be checked periodically and tightened if necessary.

LOCKING SWITCH IN THE “OFF” POSITION

IMPORTANT: When the miter saw is not in use, the switch should be locked in the "OFF" position, using a padlock (B) Fig. 14 with a 3/16" diameter shackle to prevent unauthorized use of the saw.

In the event of a power outage, always lock switch in “OFF” position until the main power is restored.
