Commissioning
Installing sanding disc and disc guard, Fig. 4
WARNING: Do not connect to power supply until assembly
is complete. Failure to comply could result in accidental
starting and possible serious injury.
• Remove the backing from the sanding disc.
• Align perimeter of sanding disc with plate and press
firmly into position.
• Position disc guard against the lower one­third of the
disc, aligning holes as shown in figure 4.
• Using the two phillips head screws, securely tighten the
disc guard into place.
Installing/Replacing sanding belt, Fig. 5.
On the smooth side of the sanding belt, there is a direc-
tional arrow. The sanding belt must run in the direction of
the arrow.
• Pull the tension lever toward you to release belt ten-
sion.
• Place the sanding belt over the drive drum and idler drum
with the directional arrows running counterclockwise. Be
sure the sanding belt is centered on both drums.
• Push the tension lever back into place to apply the belt
tension.
Note: The tension lever is spring loaded so use extreme
caution when pushing the tension lever back into place to
avoid personal injury.
Mounting the worktable for use with the disc sander, Fig. 6
To use the worktable with the disc sander:
• Insert the index pin into the hole as shown in figure 6.
• Position the worktable not further than 1/16 in. (1.6
mm) from the sanding surface.
• Using a hex key, tighten the hex set screw securely.
Mounting the worktable for use with the belt sander, Fig. 7
To use the worktable for vertical sanding:
• Insert the index pin into the hole as shown in figure 7.
• Position the worktable not further than 1/16 in. (1.6
mm) from the sanding surface.
• Using a hex key, tighten the hex set screw securely.
CAUTION: To avoid trapping the workpiece or your fingers
between the table and the sanding surface, the table edge
should NEVER be further from the sanding surface than
1/16 in (1.6 mm).
Assembling work support, Fig. 8.
• Place the work support over the holes in the side of the
tool housing.
• Using a hex key, fasten in place with the washers and
socket head screws.
Mounting belt/disc sander to work bench, Fig. 9
If your belt/disc sander is to be used in a permanent loca-
tion, it is recommended you secure it to a workbench or
other stable surface. When mounting the belt/disc sander
to a workbench, holes should be drilled through the sup-
porting surface of the workbench.
• Mark holes on workbench where belt/disc sander is to be
mounted using holes in the base as a template for hole
pattern.
• Drill holes through workbench.
• Place belt/disc sander on workbench aligning holes in
the base with holes drilled in the workbench.
• Insert bolts (not included) and tighten securely with lock
washers and hex nuts (not included).
Note: All bolts should be inserted from the top. Install the
lock washers and hex nuts from the underside of the work-
bench.
Clamping belt/disc sander to work bench, Fig. 10
If your belt/disc sander is to be used as a portable tool, it
is recommended you fasten it permanently to a mount-
ing board that can easily be clamped to a workbench or
other stable surface. The mounting board should be of
sufficient size to avoid tipping while belt/disc sander is
in use. Any good grade plywood or chipboard with a 3/4
in. (19 mm) thickness is recommended.
• Mark holes on board where belt/disc sander is to be
mounted using holes in the base as a template for hole
pattern.
• Follow last three steps in section Mounting Belt/Disc
Sander to Workbench.
If lag bolts are used, make sure they are long enough to
go through holes in belt/disc sander base and material the
belt/ disc sander is being mounted to. If machine bolts are
used, make sure bolts are long enough to go through holes
in belt/disc sander, the material being mounted to, and the
lock washers and hex nuts.
Adjustments
WARNING: Before performing any adjustment, make sure
the belt/disc sander is unplugged from the power supply
and the switch is in the OFF position. Failure to heed this
warning could result in serious personal injury.
Adjusting the belt tracking, Fig. 11
• Plug in belt/disc sander.
To check belt tracking:
• Turn the switch ON and then immediately turn it OFF. If
the belt tends to slide off the idler drum or drive drum,
the belt is not tracking properly.
To adjust belt tracking:
• If the sanding belt moves toward the disc, turn the track-
