Auxiliary Handle
An auxiliary handle is provided with your tool for convenience. The
handle can be screwed into either side of the gear case, as shown in
Figure 2, and should be used at all times when sanding or grinding.
Sanding With Abrasive Discs
Abrasive discs can be used for smoothing welds, removing rust and
paint and general smoothing of rough surfaces.
To install an abrasive disc, follow the steps listed below.
1. TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
2. Push the hub of the disc nut through the hole in the center of the
abrasive disc and the backing disc as far as it will go.
3. Install the assembled discs onto the tool spindle, as shown in
Figure 3, and engage the disc nut into the disc nut hub.
4. Using a glove or cloth to protect your hand, screw the whole
assembly clockwise onto the tool spindle as far as it will go as
shown in Figure 4.
5. Engage the spindle lock button to lock the spindle in place and
tighten firmly. (See Figure 4)
To remove an abrasive disc, follow the steps listed below.
1. Turn off and unplug the tool from the power supply.
2. Using a glove or cloth to protect your hand, turn the assembled
discs counterclockwise as you depress the spindle lock button.
When sanding, maintain an angle of 10-15 degrees between the
abrasive disc and the surface being sanded, as shown in Figure 5.
If only the outer edge of the abrasive disc is used, a rough cut surface
will result. If the disc is pressed flat against the surface, the sanding
action will be bumpy and irregular and the tool will be difficult to
control.
