back to be approximately 5mm higher than the front.
4. Adjust leveling screws as needed, then tighten nuts.
9.0 ELECTRICAL CONNECTIONS
Electrical connections must be made by a qualifi ed
electrican in compliance with all relevant codes. This
machine must be properly grounded to help prevent
electrical shock and possible fatal injury.
9.1 GROUNDING INSTRUCTIONS
The ECB-1422V is prewired for 230V, 3 phase, and can
be converted to 460V 3 phase. Confi rm that power available at the saw’s location matches that for which the saw
is wired.
The machine is not provided with an electrical plug; it can
be “hardwired” directly to a service panel.
It is recommended that the band saw be connected to a
dedicated 20 amp circuit with circuit breaker or time-delay
fuse marked “D”. Local codes take precedence over
recommendations.
Before connecting to power source, be sure switch is in off
position.
Fig. 7-1
8.0 COOLANT
Cutting fl uid or coolant must be supplied by the operator.
See sect. 14.4 for information.
Check with a qualifi ed electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to whether
the tool is properly grounded. Failure to comply may
cause serious or fatal injury.
Permanently connected tools: This tool should be connected to a grounded metal permanent wiring system; or
to a system having an equipment-grounding conductor.
Make sure a disconnect is available for the operator.
During hard-wiring of the machine, make sure the fuses
have been removed or the breakers have been tripped
in the circuit to which the band saw will be connected.
ALWAYS FOLLOW PROPER LOCK-OUT/TAG-OUT PROCEDURES.
