Craftsman 351.21 4300 Saw User Manual


 
POWER SOURCE
Band saw requires a 115 or 230 volt, 60 Hz power
source. Band saw is shipped with motor and controls
prewired for 115 volt operation. Line cord does not
have plug. A 115 volt, 20/30A three-prong plug must
be attached to the line cord.
The motor is designed for operation on the voltage and
frequency specified. Normal loads will be handled safe-
ly on voltages not more than 10% above or below the
specified voltage.
Running the unit on voltages which are not within
the range may cause overheating and motor burn-out.
Heavy loads require that the voltage at motor terminals
be no less than the voltage specified. Power supply to
the motor is controlled by a double pole locking rocker
switch. Remove the key to prevent unauthoriFed use.
GROUNDING INSTRUCTIONS
WARNING: Improper connection of equipment
grounding conductor can result in the risk of electrical
shock. Equipment should be grounded while in use to
protect operator from electrical shock.
Check with a qualified electrician if grounding instruc-
tions are not understood or if in doubt as to whether
the tool is properly grounded.
Green (or green and yellow) conductor in cord is the
grounding wire. If repair or replacement of the electric
cord or plug is necessary, do not connect the green
(or green and yellow) wire to a live terminal.
Many cover plate screws, water pipes and outlet boxes
are not properly grounded. To ensure proper ground,
grounding means must be tested by a qualified
electrician.
To use the band saw with a 230V power supply:
WARNING: All electrical connections must be
performed by a qualified electrician.
Have a qualified electrician attach a 230 volt,
20/30A 3-prong plug band saw line cord.
Open cover (Figure 17, Key No. 8) by removing
eight pan head screws.
Change wire from 115V terminal of transformer
to the unused 230V terminal (See Figure 2).
Change amperage setting on the thermal overload
relay (See Figure 2).
Replace cover.
