Fence Locking Tightness; Dust Collection; Electrical Connections; Single Phase Connections - Powermatic PM1800B Operating Instructions And Parts Manual

8.12 Fence locking tightness

Tightness of the fence against the guide rail can be
adjusted by rotating the two back screws (B, Figure
16). Rotate the two screws equally (clockwise to
tighten) with the hex wrench.
Because these screws are also used to align the
fence to the blade, after adjusting fence locking
tightness, you should double check fence-to-blade
relationship, as explained under sect. 8.11.

8.13 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 – 600 CFM is recommended.
Figure 18: dust ports
JET has a line of dust collection systems available;
see your dealer or visit our website listed on the
cover.
Connect the hoses of your dust collection system to
the 4" dust ports at rear of band saw. Secure tightly
with hose clamps (not provided). See Figure 18.

9.0 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.

9.1 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 30-amp
circuit with circuit breaker or time delay fuse marked
"D".
Local codes
recommendations.

9.2 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.
It is recommended that the three phase Band Saw
be connected to a grounded and dedicated 20-amp
circuit with circuit breaker or time delay fuse marked
"D".
Local codes
recommendations.
9.2.1 Voltage conversion
The three phase Band Saw may be converted to
460V operation:
1. Replace 230V contactor with 460V magnetic
contactor (part no. PM1800B-043C, purchased
separately).
2. Re-connect motor leads according to diagram
inside motor junction box. (Similar diagrams are
found in sect. 18.0 of this manual.)
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.

9.3 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.
