INSTALLATION (CONTINUED)
Electrical Connections
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 120/240 volts. Motor is prewired at the factory for
120 volts.
• To use the grinder with a 240V power supply, have a qualified
electrician rewire motor and attach a 240 volt, 15A three-prong
plug onto grinder line cord.
OPERATION
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.
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 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
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 and disc to come up
to full speed before sanding or grinding.
• Abrasive belt must travel towards tool rest.
• Avoid kickback by grinding 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 tool rest when grinding with belt/disc.
• Never push a sharp corner of workpiece rapidly against
belt/disc. Abrasive backing may tear.
• Replace abrasives when they become loaded (glazed) or
frayed.
• When grinding metal, move workpiece across abrasive to
prevent heat build-up.
• Never attempt wet sanding. If work-piece becomes too hot to
handle, cool it in water.
• Do not expose to rain or use in damp locations.
Replacing Abrasive Belt
Refer to Figure 6, page 10.
Abrasive belt should be replaced when worn, torn, or glazed.
Loosen belt cover knobs (Ref. No. 18) and open belt cover.
1. Release belt tension by pushing tension lever (Ref. No. 35)
towards idler drum. Slide old belt off the idler and drive wheels.
NOTE: There may be an arrow on the inside of the belt. The arrow
should point down toward the belt table to ensure that the splice in
the belt will not come apart.
2. Slide new belt over the drive and idler drums; center belt on
drums.
3. Push tension lever towards drive drum to tension belt.
4. Rotate belt by hand to check tracking. Belt should ride
centered on drive and idler drums. Adjust thumb nut (Ref. No.
29) as needed to center belt on drums. When belt tracks
properly, tighten hex nut. (Ref. No. 28) If adjustment of thumb
nut does not provide desirable tracking, adjust the stud (Ref.
No. 30) using a flat screwdriver. To adjust stud, loosen hex nut
and turn stud counterclockwise to move belt to the right or
clockwise to move belt to the left until belt rides centered on
drive and idler drums. Tighten hex nut while holding the stud in
place.
5. Close belt cover and tighten knobs.
Adjust Belt Assembly Position
Refer to Figure 6, page 10.
Sanding belt assembly can be adjusted from horizontal to vertical
position.
1. Loosen socket head bolt (Ref. No. 37 is threaded into pivot
bracket.
2. Tilt belt assembly to desired position (from horizontal to
vertical). Secure belt assembly position by tightening socket
head bolt in pivot bracket.
