USE PROPER EXTENSION CORDS .

Use proper extension cords. Make sure your extension
cord is in good condition and is a 3-wire extension cord
which has a 3-prong grounding type plug and a 3-hole
receptacle which will accept the tool's plug. When
using an extension cord, be sure to use one heavy
enough to carry the current of the tool. An undersized
cord will cause a drop in line voltage, resulting in loss of
power and overheating. Fig. 17, shows the correct
gauge to use depending on the cord length. If in doubt,
use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
OPERATING CONTROLS
AND ADJUSTMENTS
STARTING AND STOPPING
SANDER
The on/off switch (A) Fig. 18, is located on the sander
base. To turn the sander "ON", move the switch to the
up position. For "OFF", move the switch down.
LOCKING SWITCH IN THE "OFF"
POSITION
IMPORTANT: When the tool is not in use, the switch
should be locked in the "OFF" position to prevent
unauthorized use. To lock the switch, grasp the switch
toggle (B) and pull it out of the switch (Fig. 19). If the
switch toggle is removed while the sander is running, the
tool can be turned "OFF", but cannot be restarted with-
out inserting the switch toggle (B).
CHANGING ABRASIVE SLEEVES
AND SANDING DRUMS
1. DISCONNECT THE TOOL FROM THE POWER
SOURCE.
2. Remove table insert (A) Fig. 20.
3. Use the supplied socket wrench (B) Fig. 20, to
remove the arbor screw counter-clockwise. Remove the
abrasive sleeve (C) with the sanding drum from the
spindle assembly.
