8.6 Length stop

Refer to Figure 8-5.
1. Screw the lower rod into the threaded hole in
the base. Orient the rod so that the graduated
scale is visible, and tighten the hex nut with a
19mm wrench to secure.
2. Calibrate the length stop: Lower the blade, and
loosen the knobs on the rod holder. Then slide
the upper rod into contact with the blade, and
adjust the rod holder so that its left edge aligns
with the zero. Retighten the top knob to secure
the zero setting.

9.0 Electrical connections

Electrical connections must
be made
electrician in compliance with all relevant
codes. This machine
grounded to help prevent electrical shock and
possible fatal injury.
On all models, if a machine is being hard-wired to a
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 cold
saw will be connected. Place a warning placard on
by a qualified
must be properly
the fuse holder or circuit breaker to prevent it being
turned on while the machine is being wired.
See Table 2 for recommended circuit sizes for your
particular model. NOTE: Local codes take
precedence over recommendations.
Recommended circuit size
CS-275 (3PH 230V)
CS-275-1 (1PH,115/230V)
CS-315 (3PH 230V)
CS-315-1 (1PH, 230V)

9.1 Three-phase models

The CS-275 (3-phase) and CS-315 (3-phase) are
rated for 230-volt only power. They are not
supplied with a plug. You may either install a
proper 230V UL/CSA listed plug, or "hardwire" the
machine directly to a service panel.
After wiring, make sure that the blade rotates in the
proper direction. If it does not, reverse two of the 3-
phase wires on the supply input.

9.2 Single-phase models

The CS-315-1 (single phase) is rated for 230-volt
only power. It is not supplied with a plug. You may
either install a proper 230V UL/CSA listed plug, or
"hardwire" the machine directly to a service panel.
The CS-275-1 (single phase) is rated for
115/230V, prewired for 115V and supplied with a
120-volt rated plug. It may be converted to 230V.
See section 9.3.
9.3 Voltage conversion (model CS-
275-1 only)
To convert from 115V to 230V:
1. Remove the panel from the control box.
2. On the transformer, reconnect the L11 line
from the 120V terminal to the 230V terminal
(A, Figure 9-1).
3. Replace the 20 amp fuses with 10 amp fuses
in the first two fuse holders (B, Figure 9-1).
