SANDING BELT

The belt will wear at different rates depending on the
type of material being sanded and the pressure being
applied to the workpiece.
1. Slide the tensioner to the right to release belt tension
as in Fig. 6.
2. Remove the worn belt from the drive mechanism as
shown in Fig. 7, taking note of the direction of travel
of the belt (towards the left hand end of the machine
denoted by the dust extraction port).
3. Place the new belt in position over the drums as
shown in Fig.8, with the edge of the belt aligned with
the rear of the drums then release the tensioner to
grip the belt.
4. Before using, check the tracking as described in
"Belt Tracking" and adjust as necessary.

BELT TRACKING

The belt-tracking adjustment is set at the factory so that
the abrasive belt will run true on the drums. If however,
the belt should track to one side or the other, an
adjustment can be made by turning the tracking knob,
which is located on the top right hand side of the front of
the machine Fig. 9. Turn the knob clockwise to make the
belt track onto the back of the machine or anti clockwise
to track towards the front of the machine.
WARNING Be careful if turning anti
clockwise as this could make the belt
track off the side of the machine and
possibly cause personal injury.
To properly track the sanding belt:
1. Plug in the sander.
2. Turn the power switch on and then off, taking note of
whether the belt moves in its track to one side or the
other or stays with it's edge against the rear of the
drums.
3. If it does not move then the tracking is set correctly.
4. If the belt moves towards the front of the machine,
turn the tracking knob clockwise a 1/ 4 turn.
5. Turn the power switch on and then off again, taking
note of any belt movement.
6. Readjust the tracking knob another
necessary.

Your sander has been shipped assembled with the exception of
the sanding disc, disc guard, mitre gauge, sanding stop, and
worktable. Carefully remove all parts
Do not discard the packaging until the parts have been checked
against the list in Fig.2 and the sander has been fully
assembled and tested to make sure it is working correctly.

to securely mount it on a workbench using hexagon bolts,
washers and locking nuts (not supplied) to fix it using the holes
in the base mounting flanges.

or changing parts or accessories.

4. Fix the worktable (2) to the support arm (3) using the
Hex. bolts and washers (4). Attach the work table assembly
to the main body of the sander by (a) placing the spigot

the fixing screw into the threaded hole next to it to secure
it at the required angle a shown in Fig.4.
