If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances. Figure 6-1 6.2 Voltage conversion For models BGB-142, BGB-248, BGB-260-1: 1. Remove four screws from control panel, and remove panel from motor shroud. Switch incoming motor leads according to wiring diagram. 2. Reinstall control panel on motor shroud. 3. Replace plug on end of motor cord with proper UL/CSA listed plug rated for the new incoming voltage. 4. Test run the grinder. If abrasive belt moves upward instead of downward, disconnect machine from power and switch any two of the three power leads (not the green ground wire). For model BGB-260-3: 1. Remove four screws from motor shroud and remove shroud. 2. Open motor junction box and switch incoming power leads according to wiring diagram on inside cover of junction box. Diagrams are also placed at back of this manual. (In case of discrepancy, diagrams on machine take precedence.) 3. Replace magnetic starter with 460V starter; see parts list to order. 4. Re-install junction box cover and motor shroud. 5. Test run the grinder. If abrasive belt moves upward instead of downward, disconnect machine from power and switch any two of the three power leads (not the green ground wire). 6.3 Extension cords The use of extension cords is discouraged; try to position equipment within reach of the power source. For circuits which are far away from the electrical service box, the wire size must be increased in order to deliver ample voltage to the motor. To minimize power losses and to prevent motor overheating and burnout, the use of wire sizes for branch circuits or electrical extension cords according to Table 1 is recommended. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. Conductor length 0 - 50 ft. 50 - 100 ft. Over 100 ft.

Voltage conversion
For models BGB-142, BGB-248, BGB-260-1:
1.
Remove four screws from control panel, and
remove panel from motor shroud. Switch
incoming motor leads according to wiring
diagram.
2.
Reinstall control panel on motor shroud.
3.
Replace plug on end of motor cord with proper
UL/CSA listed plug rated for the new incoming
voltage.
4.
Test run the grinder. If abrasive belt moves
upward instead of downward, disconnect
machine from power and switch any two of the
three power leads (not the green ground wire).
For model BGB-260-3:
1.
Remove four screws from motor shroud and
remove shroud.
2.
Open motor junction box and switch incoming
power leads according to wiring diagram on
inside cover of junction box. Diagrams are also
placed at back of this manual. (In case of
discrepancy,
diagrams
on
machine
take
precedence.)
3.
Replace magnetic starter with 460V starter; see
parts list to order.
4.
Re-install junction box cover and motor shroud.
5.
Test run the grinder. If abrasive belt moves
upward instead of downward, disconnect
machine from power and switch any two of the
three power leads (not the green ground wire).

Extension cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
source. For circuits which are far away from the
electrical service box, the wire size must be
increased in order to deliver ample voltage to the
motor. To minimize power losses and to prevent
motor overheating and burnout, the use of wire sizes
for branch circuits or electrical extension cords
according to Table 1 is recommended. If in doubt,
use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
