INSTALLATION CONTINUED
•
Do not remove or alter grounding prong in any manner. In the
event of a malfunction or breakdown, grounding provides a
path of least resistance for electrical shock.
WARNING:
Do not permit fingers to touch the terminals of plug
when installing or removing from outlet.
•
Plug must be plugged into matching outlet that is properly
installed and grounded in accordance with all local codes and
ordinances. Do not modify plug provided. If it will not fit in out-
let, have proper outlet installed by a qualified electrician.
•
Inspect tool cords periodically, and, if damaged, have repaired
by an authorized service facility.
•
Green (or green and yellow) conductor in cord is the grounding
wire. If repair or replacement of the electric cord or plug is nec-
essary, do not connect the green (or green and yellow) wire to
a live terminal.
•
Where a 2-prong wall receptacle is encountered, it must be
replaced with a properly grounded 3-prong receptacle installed
in accordance with National Electric Code and local codes and
ordinances.
WARNING:
This work should be performed by a qualified
electrician.
•
A temporary 3-prong to 2-prong grounding adapter (See
Figure 4) is available for connecting plugs to a two pole outlet
if it is properly grounded.
•
Do not use a 3-prong to 2-prong grounding adapter unless
permitted by local and national codes and ordinances.
(A 3-prong to 2-prong grounding adapter is not permitted in
Canada.) Where permitted, the rigid green tab or terminal on
the side of the adapter must be securely connected to a per-
manent electrical ground such as a properly grounded water
pipe, a properly grounded outlet box or a properly grounded
wire system.
•
Many cover plate screws, water pipes and outlet boxes are not
properly grounded. To ensure proper ground, grounding means
must be tested by a qualified electrician.
EXTENSION CORDS
•
The use of any extension cord will cause some drop in voltage
and loss of power.
•
Wires of the extension cord must be of sufficient size to carry
the current and maintain adequate voltage.
•
Running the unit on voltages which are not within ±10% of the
specified voltage may cause overheating and motor burn-out.
•
Use the table to determine the minimum wire size (A.W.G.)
extension cord.
•
Use only 3-wire extension cords having 3-prong grounding
type plugs and 3-pole receptacles which accept the tool plug.
•
If the extension cord is worn, cut or damaged in any way,
replace it immediately.

ELECTRICAL CONNECTIONS
WARNING:
All electrical connections must be performed by a
qualified electrician. Make sure tool is off and disconnected from
power source while motor is mounted, connected, reconnected or
anytime wiring is inspected.
•
Motor and wires are installed as shown in wiring diagram (See
Figure 5. Motor is assembled with approved, 3-conductor cord
to be used at 115/230 volts. Motor is prewired at the factory for
115 volts.
•
To use the grinder with a 230V power supply, have a qualified
electrician rewire motor and attach a 230 volt, I5A three-prong
plug onto grinder line cord.
OPERATION
Refer to Figures 6 and 7.
WARNING:
Operation of any power tool can result in foreign
objects being thrown into eyes which can result in severe eye
damage. Always wear safety goggles complying with United States
ANSI Z87.1 (shown on package) before commencing power tool
operation.
CAUTION:
Always observe the following safety precautions:
•
Whenever adjusting or replacing any parts on the grinder turn
power off and remove the plug from power source.
•
Recheck tool rest bolts, they must be tightened securely.
•
Make sure all guards are properly attached. All guards should
be securely fastened.
•
Make sure all moving parts are free and clear of any interfer-
ence.
•
Make sure all fasteners are tight and have not vibrated loose.
•
With power disconnected, test operation by hand for clearance
and adjust if necessary.
•
Always wear eye protection or face shield.
•
Make sure abrasive belt tracks properly. Correct tracking gives
optimum performance.
•
After turning switch on, always allow belt to come up to full
speed before sanding or grinding.
•
Abrasive belt must travel down.
