WARNING: YOUR EDGE SANDER MUST BE CONNECTED TO
A220V, 20-AMP. MINIMUM BRANCH CIRCUIT. FAILURE TO
CONNECT IN THIS WAY CAN RESULT IN INJURY FROM
SHOCK OR FIRE.
GROUNDING
This edge sander 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 edge
sander 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.
WARNING: TO MAINTAIN PROPER GROUNDING OF YOUR
EDGE SANDER, DO NOT REMOVE OR ALTER THE
GROUNDING PRONG IN ANY MANNER.
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: IF NOT PROPERLY GROUNDED, THIS EDGE
SANDER CAN CAUSE ELECTRICAL SHOCK, PARTICULARLY
WHEN USED IN DAMP LOCATIONS. TOAVOID SHOCK OR
FIRE, IF THE POWER CORD IS WORN OR DAMAGED IN ANY
WAY, HAVE IT REPLACED IMMEDIATELY.
220V OPERATION
As received from the factory, your edge sander is ready to run for
220V operation. This edge sander 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 TWO-PRONG ADAPTORS FOR
THEY ARE NOT IN ACCORDANCE WITH LOCAL CODES AND
ORDINANCES. NEVER USE IN CANADA.
110V OPERATION
If 110V,single phase operation is desired, the following
instructions must be followed:
1. Disconnect the machine from its power source.
2. The edge sander comes with four motor leads that are
connected for 220V operation. Reconnect these four motor leads
for 110V operation, as indicated on the inside of the capacitor
cover.
3. The 220V plug supplied with the edge sander must be replaced
with a CSA listed plug suitable for 110V operation. This plug is
illustrated in Fig.2. Contact your authorized service center or
qualified electrician to install the plug and to change the
connections from 220V to 110V. The edge sander must comply
with all local and national codes after the 110V plug is installed.
4. An edge sander with a 110V plug should only be connected to an
outlet having the same configuration as illustrated by the
grounded outlet box in Fig.2. No adaptor is available or should be
used for 220V operation.
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.
