Porter-Cable RS830 - Manual (Page 5)

Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which
has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an
extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause
a drop in line voltage, resulting in loss of power and overheating. Fig. F, shows the correct gauge to use depending on
the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

CHANGING VOLTAGE
The motor supplied with your saw is wired for 120 volt
operation. If you desire to operate your saw at 240 volts,
it is necessary to reposition voltage changing switch in
the motor junction box (B) Fig. D. Proceed as follows:
1.
WARNING: DISCONNECT TOOL FROM POWER
SOURCE.
2. Remove screw (A) Fig. D, and remove nameplate
cover (B).
3.
Carefully slide switch (C) Fig. E, in motor junction
box to read 240. Replace nameplate cover and screw
which were removed in STEP 2.
4.
It is also necessary to replace the 120 volt plug
supplied with the motor with a UL/CSA listed plug
suitable for 240 volts and the rated current of the saw.
Contact your local Authorized Delta Service Center or
qualified electrician for proper procedures to install the
plug. The saw must comply with all local and national
electrical codes after the 240 volt plug is assembled.
