Adjustment

The clamping blocks (L, M, Figure 9) are
adjusted at the factory and no further adjustment
of the blade guard and riving knife assembly
should be necessary. However, proper
alignment is very important. Before operating
the table saw, read the Riving Knife Adjustment
section (page 16) to verify and follow the
adjustment procedure if necessary.

Grounding Instructions

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.

A power plug is not provided with the Model
PM3000. You may either connect the proper
UL/CSA listed plug or “hardwire” the machine
directly to your electrical panel provided there is
a disconnect near the machine for the operator.
If hard-wiring, make sure the fuses have bee n
removed or the breakers have been tripped in
the circuit to which the machine 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.

The three phase motor on the 1720305K is pre-
wired for 230 volt but may be re-connected for
460 volts by changing the connections as
illustrated in the diagram in the motor wiring box,
and by installing a 460V switch (not included –
call customer service to order stock no.
PM3000-282A).

It is recommended that the three phase PM3000
table saw when operated at 230 volts, be
connected to a dedicated, minimum 30 amp
circuit with a 30 amp circuit breaker or time
delay fuse. When operated at 460 volts,
connect the table saw to a dedicated, minimum
20 amp circuit with 20 amp circuit breaker or
time delay fuse. Local codes take precedence
over recommendations.

This machine must be grounded. Grounding
provides a path of least resistance to help divert
current away from the operator in case of
electrical malfunction.

Make sure the voltage of your power supply
matches the specifications on the motor plate of
the machine.

Extension Cords

Make sure the cord rating is suitable for the
amperage listed on the machine's motor plate.
An undersize cord will cause a drop in line
voltage resulting in loss of power and
overheating.

The chart in Table 1 shows the correct size cord
to use based on cord length and motor plate
amp rating. If in doubt, use the next heavier
gauge. The smaller the gauge number, the
heavier the cord.
