Extension Cords
Extension cords are often required on jobsites to connect
the motor. When choosing an extension cord make sure
it has adequate wire size for safety. An undersized cord
will cause a drop in line voltage resulting in a loss of power
and overheating. Refer to Table 2 when selecting exten-
sion cords. It shows the correct wire size to use depend-
ing on cord length. If in doubt, use the next heavier cord
size.
On motors being used outdoors, use extension cords
rated for outdoor use.

To reduce the risk of electric shock, motors equipped
with 3-wire grounded plugs must be properly ground-
ed. On these motors use only 3-wire grounded plugs,
receptacles, and extension cords.

Connecting Motor to Power Supply
WARNING
Improper use of extension cords can cause over-
heating or create serious fire or shock hazards.
Never
use worn or damaged cords!
Note:
Not all countries require the use of a three-wire
grounded plug for this piece of equipment. In these
countries, motors are equipped with a two-wire plug
which can be plugged into a standard electrical outlet.

1. Check that switch on motor is off before connecting
motor to power source.
2. Make sure power supply matches voltage require-
ments listed on motor label. Running a motor at a low
voltage will cause it to run slow. This will reduce
perfomance and may cause motor to overheat.
3. On motors equipped with a three wire grounded plug
use three-wire grounded receptacles
(d)
when con-
necting the motor. If a 3-wire grounded receptacle is
not available, then a grounded adapter must be in-
stalled as shown in illustration
(e)
to ensure a proper
ground connection.
