Dust Collection
The use of a dust collection system is strongly
recommended for this band saw. It will help
keep the shop clean, as well as reduce potential
health hazards caused by inhalation of wood
dust. The collector should have a capacity
sufficient for this size machine – 400 CFM is
recommended. Walter Meier has a line of dust
collection systems available; see your dealer or
visit our website listed on the back cover.
Connect the hoses of your dust collection
system to the 4” dust ports at the rear of the
band saw. Secure tightly with hose clamps (not
provided). See Figure 18.
Electrical Connections
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
Single Phase Connections
The single phase Band Saw is factory wired for
230 volts. It is not supplied with a plug. You may
either install a UL/CSA-listed plug suitable for
230 volt operation, or “hard-wire” the Band Saw
directly to a service panel.
It is recommended that the single phase Band
Saw be connected to a grounded and dedicated,
minimum 50 amp circuit with a 50 amp circuit
breaker or time delay fuse. Local codes take
precedence over recommendations.
Three Phase Connections
The three phase Band Saw is factory wired for
230 volts. It is not supplied with a plug. You may
either install a UL/CSA-listed plug suitable for
230 volt operation, or “hard-wire” the Band Saw
directly to a service panel.
The three phase Band Saw may be converted to
460V operation. The current contactor must be
replaced with the 460V magnetic contactor (part
no. PM2000-293C, purchased separately). In
addition, re-connect the motor leads according
to the diagrams inside the motor junction box.
(Similar diagrams may be found at the back of
this manual.)
It is recommended that the three phase Band
Saw be connected to a grounded and dedicated,
minimum 30 amp circuit with a 30 amp circuit
breaker or time delay fuse. Local codes take
precedence over recommendations.
Figure 18
If the single phase or three phase Band Saw is
to be “hard-wired” to a service panel, 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. Place a warning placard on the
fuse holder or circuit breaker to prevent it being
turned on while the machine is being wired.
Grounding Instructions
This machine must be grounded. In the event of
a malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock.
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes, is the equipment-
grounding conductor.
If repair or replacement of the electric cord or
plug is necessary, do not connect the
equipment-grounding conductor to a live
terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded. Repair or
replace a damaged or worn cord immediately.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the Band Saw.
