ELECTRICAL INFORMATION
WARNING!
ALL ELECTRICAL CONNECTIONS MUST BE DONE BY A QUALIFIED ELECTRICIAN. FAILURE TO COMPLY MAY RESULT IN
SERIOUS INJURY! ALL ADJUSTMENTS OR REPAIRS MUST BE DONE WITH THE MACHINE DISCONNECTED FROM THE
POWER SOURCE. FAILURE TO COMPLY MAY RESULT IN SERIOUS INJURY!
POWER SUPPLY
WARNING:
YOUR MORTISER MUST BE CONNECTED TO A
110V, 15-AMP CIRCUIT BREAKER. FAILURE TO CONNECT IN
THIS WAY CAN RESULT IN INJURY FROM SHOCK OR FIRE.
GROUNDING
This Mortiser must be grounded. If it should malfunction or
breakdown, grounding provides a path of least resistance for
electric current, to reduce the risk of electric shock. This Mortiser
is equipped with a cord having an equipment-grounding conductor
and grounding plug. The plug must be plugged into an appropriate
outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
Your Mortiser must be properly grounded. Not all outlets are
properly grounded. If you are not sure if your outlet is properly
grounded, have it checked by a qualified electrician.
WARNING:
TO MAINTAIN PROPER GROUNDING OF YOUR
MORTISER, DO NOT REMOVE OR ALTER THE GROUNDING
PRONG IN ANY MANNER.
WARNING:
IF NOT PROPERLY GROUNDED, THIS MORTISER
CAN CAUSE ELECTRICAL SHOCK, PARTICULARLY WHEN
USED IN DAMP LOCATIONS. TO AVOID SHOCK OR FIRE, IF
THE POWER CORD IS WORN OR DAMAGED IN ANY WAY,
HAVE IT REPLACED IMMEDIATELY.
110V OPERATION
As received from the factory, your Mortiser is ready to run for 110V
operation. This Mortiser is intended for use on a circuit that has an
outlet and a plug which looks like the one illustrated in Fig.1.
WARNING:
DO NOT USE A TWO-PRONG ADAPTOR FOR
THEY ARE NOT IN ACCORDANCE WITH LOCAL CODES AND
ORDINANCES. NEVER USE IN CANADA.
EXTENSION CORDS
The use of any extension cord will cause some loss of power. Use
the following table to determine the minimum wire size (A.W.G-
American Wire Gauge) extension cord. Use only 3-wire extension
cords which have 3-prong grounding type plugs and 3-hole
receptacles which accept the tool’s plug.
For circuits that are further away from the electrical circuit box, the
wire size must be increased proportionately in order to deliver ample
voltage to the Mortiser motor. Refer to Fig.2 for wire length and size.
