POWER REQUIREMENTS
DANGER
• To reduce the risk of
electric shock, check
the electrical source for
proper grounding.
• Before performing any
maintenance on the
tool, disconnect the
power cord from the
electrical source.
Failure to follow these instructions could
result in death or serious personal injury.
The HCT908 tool is equipped with a three-
prong plug and must be plugged into a
grounded, single-phase electrical receptacle .
Refer to Figure “A” below . If an adapter (Figure
“C”) is used to accommodate the three-prong
plug, the adapter’s wire must be attached to a
known ground . Refer to Figures “A” and “B”
and the “Power Supply Requirements” table
on this page .
NEVER REMOVE THE THIRD
PRONG FROM THE DRILL MOTOR’S POWER
CORD PLUG

NOTICE
• The tool is equipped with a UL Listed
three-conductor cord and a three-prong,
grounding-type plug to fit the proper
grounding-type receptacle. The green (or
green and yellow) conductor in the cord
is the grounding wire. Never connect the
green (or green and yellow) wire to a live
terminal.
EXTENSION CORD REQUIREMENTS
When pre-wired outlets are not available and
an extension cord must be used, it is important
to use the proper cord size (i .e . Conductor Size
American Wire Gauge) . Cord size selection is
based upon tool rating (amps) and cord length
(feet) . Use of a cord size (gauge) thinner than
required will cause significant voltage drop
at the power head while the tool is operating .
Voltage drops may cause damage to the power
head and can result in improper tool operation .
NOTE:
It is acceptable to use a cord size that is
thicker than required .
The required cord sizes for cord lengths up to
and including 100 ft/31 m are listed in the table
below . Use of extension cords longer than 100
ft/31 m must be avoided .
