INSTALLATION (CONTINUED)
WARNING:
This work should be performed by a qualified
electrician.
A temporary 3-prong to 2-prong grounding adapter (See Figure 5)
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 permit-
ted 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 permanent
electrical ground such as a properly grounded water pipe, a prop-
erly 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 extension cord must be sufficient in size to carry and
maintain adequate voltage.
•
Do not use extension cords over 25 ft. Cord must be at least 18
A.W.G.
•
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, re-
place it immediately.

OPERATION
Refer to Figures 6 and 7.
WARNING:
Operation of any power tool can result in foreign ob-
jects being thrown into eyes which can result in severe eye dam-
age. Always wear safety goggles complying with United States
ANSI Z87.1 before commencing power tool operation.
CAUTION:
Always observe the following safety precautions:
•
Whenever adjusting or replacing any parts on the sander turn
power off and remove the plug from power source.
•
Recheck table knobs and 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 interference.
•
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.
•
Be sure motor runs clockwise on disc side. Abrasive belt must
travel down.
•
Avoid kickback by sanding in accordance with the directional
arrows.
•
Keep your hands clear of abrasive belt, disc and all moving parts.
•
For optimum performance do not stall motor or reduce speed.
Do not force the work into the abrasive.
•
Support workpiece with belt table when sanding with belt, with
disc table when sanding with disc.
•
Never push a sharp corner of workpiece rapidly against belt or
disc. Abrasive backing may tear.
•
Replace abrasives when they become loaded (glazed) or frayed.
•
When grinding metal, move workpiece across abrasive to pre-
vent heat build-up.
•
Never attempt wet sanding. If work-piece becomes too hot to
handle, cool it in water.
BELT INSTALLATION
Refer to Figure 6.
Sanding belt should be replaced when worn, torn, or glazed.
1. Release belt tension by pulling down on tension handle. Slide
old belt off the drive and tracking wheels.
2. Pull down on the tension handle and slide new belt over the
drive and tracking wheels, center belt on wheels.
3. Replace lower guard and tighten bolt.
4. Replace belt cover and knobs.
5. Rotate belt by hand to check tracking, belt should ride centered
on drive and tracking wheels. Adjust socket head bolt at top of
tracking bracket to track belt properly. Be sure to secure socket
head bolt with hex nut.
ADJUST BELT TABLE
Refer to Figure 6.
1. To adjust belt table angle, loosen socket head bolt.
2. Tilt belt table to desired position and secure by tightening
socket head bolt.
