Use and Care Manual

13
Make sure your extension cord is in good condition,
and is heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating.
Table 2 shows the correct size to use depending on
cord length and nameplate ampere rating. If in
doubt, use the next heavier gage. The smaller the
gage number (AWG), the heavier the cord.

7.3 Voltage conversion
The grinder/belt sander is prewired for 115 volt input
power, but can be converted to 230 volt input, as
follows.
7.3.1 Non-variable speed models (IBGB-
248 and IBGB-436)
1. Turn grinder over and remove base plate.
2. Reconnect the leads according to wiring
diagram in sect. 13.0.
3. Remove existing plug from power cable and
attach a UL/CSA listed plug designed for 230V
power.
7.3.2 Variable speed models (IBGB-
248VS and IBGB-436VS)
Remove existing plug from power cable and attach
a UL/CSA listed plug designed for 230V power.
8.0 Adjustments
8.1 Eye shield tilt adjustment
1. Loosen lock knob (A
1
, Figure 8-1).
2. Adjust eye shield (A
2
) to desired tilt angle.
3. Tighten lock knob.
Figure 8-1: eye shield adjustment
8.2 Spark guard
As the wheel wears down, the spark guard must be
re-adjusted to maintain a 1/16" distance.
Refer to Figure 8-1.
1. Loosen two hex cap screws (B
1
) with 14mm
wrench.
2. Slide spark guard (B
2
) to 1/16" distance from
grinding wheel surface.
3. Tighten screws (B
1
).
8.3 Tool rest
As the wheel wears down, the tool rest must be re-
adjusted to maintain a 1/16" distance.
Refer to Figure 8-1.
1. Loosen two hex cap screws (C
1
) with 14mm
wrench.
2. Slide tool rest (C
2
) to a distance of 1/16" from
grinding wheel.
3. Tighten screws (C
1
).
8.4 Sanding arm tilt
Loosen screw (A, Figure 6-5) and manually move
arm to vertical or horizontal position. Retighten
screw.
Make sure screw is tight when
using sanding arm. Failure to comply may result
in vertical sanding arm falling back into
horizontal position during operation, resulting
in possible injury.
8.5 Sanding belt tracking
1. Turn grinder/sander OFF.
2. Move sanding belt by hand to check tracking. If
belt migrates to one side or the other, adjust as
follows.
3. Loosen wing nut (E, Figure 8-2).
