tired, intoxicated or when taking medications that cause

drowsiness.

PREPARE WORK AREA FOR JOB

* Keep work area clean. Cluttered work areas invite accidents.
* Do not use power tools in dangerous environments. Do not

use power tools in damp or wet locations. Do not expose
power tools to rain.

* Work area should be properly lighted.

* Proper electrical receptacle should be available for tool.

Three prong plug should be plugged directly into properly
grounded, three-prong receptacle.

* Extension cords should have a grounding prong and the three

wires of the extension cord should be of the correct gauge.

* Keep visitors at a safe distance from work area.
* Keep children out of workplace. Make workshop childproof.

Use padlocks, master switches or remove switch keys to
prevent any unintentional use of power tools.

TOOL SHOULD BE MAINTAINED

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. Safety goggles are available at Sears
retail stores or catalog.

CAUTION: Always observe the following safety precautions.
SAFETY PRECAUTIONS

• Whenever adjusting or replacing any parts on the tool, turn
switch OFF and remove the plug from power source.

• Recheck table handles. 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 to verify
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.

• Keep your hands clear of abrasive belt 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 table when sanding with belt.

• Never push a sharp corner of the workpiece rapidly against
belt. Abrasive backing may tear.

• Replace abrasives when they become loaded (glazed) or
frayed.

WARNING: Some dust created by power sanding, sawing,
grinding, drilling and other construction activities contains

chemicals known to cause cancer, birth defects or other
reproductive harm.

Some examples of these chemicals are:
° Lead from lead-based paints.
° Crystalline silica from bricks and cement and other mason-

ry products.

° Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures vary, depending on how often

you do this type of work. To reduce your exposure to these

chemicals: work in a well ventilated area and work with
approved safety equipment. Always wear MSHA/NIOSH

approved, properly fitting face mask or respirator when using
such tools.

ABRASIVE BELT FINISHING
° Finishing flat surfaces: Hold workpiece firmly with both

hands; keep fingers away from abrasive belt.
Use work stop. Work stop is used to position and secure

work being sanded. Keep end butted against work stop and
move work evenly across abrasive belt. Use extra caution
when finishing very thin pieces.

Finishing long pieces: remove work stop. Apply only
enough pressure to allow abrasive belt to remove material.

° Finishing curved edges: Finish outside curves on flat por-

tion of abrasive belt. Finish inside curves on idler drum por-
tion of abrasive belt.

° Finishing end grain: It is more convenient to finish ends of

long workpieces with the abrasive belt in a vertical position.

° For accuracy use miter gauge.
° Adjust belt table angle for beveled work.

° Belt oscillation may be stopped by pulling on black washer

on gearbox assembly. Press in on washer to restart oscilla-
tion. Do not ajdust belt tracking with oscillation stopped.

USING MITER GAUGE
Refer to Figure 5.
° Use the miter gauge for securing the work and holding the

proper angle while sanding.

° Adjust angle by repositioning the miter gauge (Key No. 15).

Loosen the knob (Key No. 17) to reposition miter gauge.

° Tighten the knob to secure miter gauge position.
° Use a combination square to adjust miter gauge square to

belt. Scale should be at zero. Loosen screw (Key No. 13)
and reposition pointer (Key No. 12) if necessary.

ADJUSTING BELT HOUSING
Refer to Figure 5.

The belt housing can be positioned at a full vertical position, a
full horizontal position, or at any angle in between which is
convenient for the sanding operation.

To adjust belt housing position:
° Loosen locking handle (Key No. 3).

° Push belt housing to move to the desired angle.
° A positive stop bolt (Key No. 27) is provided to stop the belt

housing at the full horizontal position.

° Tighten locking handle to secure belt housing position.
TABLE ADJUSTMENT

Refer to Figure 5.
° To move table vertically, loosen locking handle (Key No.

37). Reposition table and secure in position.

HORIZONTAL BELT SANDING
Refer to Figure 4.

• Adjust the belt housing to full horizontal position as
described in the above section, "Adjusting Belt Housing".

• Idler drum (Key No. 3) can be used as a contact drum to
sand curved surfaces.

USING AUXILIARY TABLE

When using the idler drum for contour sanding, it is recom-
mended that the auxiliary table be positioned so that the
workpiece will be at the center of the idler drum. This will
assure proper belt tracking and prevent the edge of the work-
piece from becoming tapered.

NOTE: Use auxiliary table only with belt housing in vertical
position.

BELT TRACKING

Refer to Figure 4.
Belt (Key No. 59) should oscillate around center on drive and

idler drums (Key Nos. 3 and 35). The sander is shipped with
the tracking mechanism properly adjusted. However, if adjust-
ment is necessary:

• Turn the unit on.

• Insert a _/8"or %2"hex wrench into the hole on adjusting nut
(Key No. 13) on either side.

• Turn the adjusting nut to the right to move belt toward you
or turn the adjusting nut to the left to move belt away from

you.

• Turn the unit off.

REPLACING BELT

Refer to Figure 4.

• Sanding belt must be replaced when worn, torn, or glazed.

• Turn the belt tension handle toward drive drum (Key No. 16)
to release belt tension.

• Loosen and remove four knobs (Key No. 61) from the rear
of the sander.

• Remove belt cover (Key No. 60).

• Slide old belt off the drive and idler drums (Key Nos. 3 and

35).

NOTE: There may be an arrow on the inside of the belt. The
arrow should point in direction of rotation to ensure that the
splice in the belt will not come apart.

• Slide new belt over the drive and idler drums; center belt on
drums.

• Push the belt tension handle toward the idler drum to
tension belt.

• Replace belt cover using knobs.

• Wear a protective glove and manually rotate the belt by
hand to check tracking. If tracking needs to be adjusted,
follow steps described in "Belt Tracking".

WARNING: Make certain that the unit is disconnected from
power source before attempting to service or remove any
component.

CLEANING
Keep machine and workshop clean. Do not allow sawdust to

accumulate on the tool. Keep the drums clean. Dirt on drums
will cause poor tracking and belt slippage. Operate tool with
dust collector to keep dust from accumulating.

Be certain motor is kept clean and is frequently vacuumed
free of dust.

Use soap and water to clean painted parts, rubber parts and
plastic guards.

LUBRICATION

The shielded ball bearings in this tool are permanently lubri-
cated at the factory. They require no further lubrication.

• When operation seems stiff, a light coat of paste wax
applied to the tables will make it easier to feed the work
while finishing.

• Do not apply wax to the belt platen. Belt could pick up wax
and deposit it on the drums causing belt to slip.

• Periodically use a grease gun to add grease to gearbox
assembly through grease nipple.

KEEP TOOL IN REPAIR
° If power cord is worn, cut, or damaged in any way, have it

replaced immediately.

• Replace worn abrasives when needed.

• Replace any damaged or missing parts. Use parts list to

order parts.

Any attempt to repair motor may create a hazard unless
repair is done by a qualified service technician. Repair service
is available at your nearest Sears store.
