4, Maintenance .............................. 16

5. Stability Of Machine

If there is any tendency for the machine to tip

over or move during certain operations such as when sanding tong heavy boards, the

sander should be bolted down.

w Location

The machine should be positioned so neither the operator nor a casual observer is forced

to stand in line with the sanding belt or disc.

This machine is intended for indoor use only.

, Kickback

When sanding on the Disc, always apply the

workpiece left of center to the left side of the disc. Applying the workpiece to the right side could cause it to fly up (kickback) which

could be hazardous.

Protection: Eyes, Hands, Face, Hears, Body

a. Always wear safety goggles (not glasses)

that comply with ANSI Z87.1, Wear face shield if operation is dusty. Wear ear plugs or muffs during extended periods of opera- tion. Do not wear gloves, jewelry or watch- es. Roll long sleeves above the elbow. Tie back long hair.

b. Do not sand pieces of material too small

to hold by hand.

c. Avoid awkward hand positions, where a

sudden slip could cause a hand to move into the sanding disc or belt.

d. Never climb on the machine. e. Never turn your Sander "ON" before clear-

ing the belt table and worktable of all ob_

jects.

f. Make sure the sanding belt runs in the

right direction (directional arrow on back

side of belt). Always have the tracking adjusted correctly so that the belt does

not run off the pulleys.

g. Hold the work firmly when sanding on the

belt and against the worktable when sanding on the disc.

h. Always adjust the worktable to within a

maximum of 1/16-inch of the sanding disc

or belt.

i. When sanding a large piece of material,

provide additional support at table height.

j. Never leave the machine work area when

the power is on, before the machine has come to a complete stop, or without re-

moving and storing the switch key.

k. Do not perform layout, assembly or setup

work on the table while the sander is operating.

I. Turn sander "OFF" and remove plug from

power supply outlet before installing or removing an accessory.

m.Use only RECOMMENDED ACCESSORIES

listed on page 17,

If any part of this belt and disc sander should break, bend, or fail in any way or any electri-

cal component fail to perform properly, or if any is missing, shut off power switch, re- move power supply cord from power supply and replace damaged missing andtor failed parts before resuming operation.

10. Do not sand with the workpiece unsupported. Support it with the backstop or worktable. The only exception is curved work performed on outer end of belt (idler pultey).

11. To avoid entanglement in spindle, do not operate sander with sanding plate and or guard removed.

CAUTION: This Belt and Disc Sander is designed to sand wood or wood like products only.

Attempts to sand or grind other materials could

For replacement motor refer to parts list in this

manual.

CONNECTING TO POWER SUPPLY OUTLET

This machine must be grounded while in use to protect the operator from electric shock.

Plug power cord ,into a 110-120V properly ground- ed type outlet protected by a 15-amp. fuse or cir-

cuit breaker.

WARNING: DO NOT PERMIT FINGERS TO TOUCH THE TERMINALS OF PLUGS WHEN INSTALLING OR REMOVING THE PLUG TO OR

FROM THE OUTLET,

WARNING: IF NOT PROPERLY GROUNDED THIS POWER TOOL CAN CAUSE AN ELECTRI- CAL SHOCK PARTICULARLY WHEN USED IN DAMP LOCATIONS CLOSE TO PLUMBING. IF AN ELECTRICAL SHOCK OCCURS THERE IS THE POTENTIAL OF A SECONDARY HAZARD SUCH AS YOUR HANDS CONTACTING THE

SANDING SURFACE, If power cord is worn or cut, or damaged in any

way, have it replaced immediately.

Your unit is for use on 110420 volts, and has a plug that looks like below.

GROUNDED 3-PRONGOUTLET

This power tool is equipped with a 3-conductor cord and grounding type plug which has a

grounding prong, approved by Underwriters'

Laboratories and the Canadian Standards Associ-

ation. The ground conductor has a green jacket

and is attached to the tool housing at one end

and to the ground prong in the attachment plug at the other end.

This plug requires a mating 3-conductor ground- ed type outlet as shown.

if the outlet you are planning to use for this power tool is of the two prong type, DO NOT

REMOVE OR ALTER THE GROUNDING PRONG IN ANY MANNER. Use an adapter as shown

below and always connect the grounding lug to a known ground.

It is recommended that you have a qualified elec- trician replace the TWO prong outlet with a pro- perly grounded THREE prong outlet.

An adapter as illustrated is available for connect- ing plugs to 2-prong receptacles.

WARNING: THE GREEN GROUNDING LUG EX-

TENDING FROM THE ADAPTER MUST BE CON-

NECTED TO A PERMANENT GROUND SUCH AS

TO A PROPERLY GROUNDED OUTLET BOX.

NOT ALL OUTLET BOXES ARE PROPERLY

GROUNDED.

tf you are not sure that your outlet box is proper- ly grounded, have it checked by a qualified elec-

trician. NOTE: The adapter illustrated is for use only if

you already have a properly grounded 2-prong receptacle, Adapter is not allowed in Canada by

the Canadian Electrical Code.

The use of any extension cord will cause some loss of power. To keep this to a minimum and to

prevent overheating and motor burn-out, use the table below to determine the minimum wire size

(A.W.G.) extension cord.

Use only 3 wire extension cords which have 3- prong grounding type plugs and 3-prong recep-

tacles which accept the tools plug.

MOUNTING BELT AND DISC SANDER TO

WORKBENCH

If belt and disc sander is to be used in a perma-

nent location, it should be fastened securely to a firm supporting surface such as a workbench.

If mounting to a workbench, holes should be

drilled through supporting surface of the work-

bench using dimensions illustrated.

Each leg should be bolted securely using 5/16" hex nuts (not included). Screw length should be 11/2" plus the thickness of the

bench top.

Locate and mark the holes where belt and disc sander is to be mounted.

An alternate method of mounting is to fasten belt and disc sander to a mounting board. The board should be of sufficient size to avoid tip-

ping of sander while in use. Any good grade of plywood or chipboard with a 3t4" minimum thick- ness is recommended. (Thinner chipboard can break.)

Drill (4) 318" diameter holes through work,

bench. :' _

Place belt and disc sander on workbench

aligning holes in feet with holes drilled in workbench.

Insert all four 5116" screws and tighten.

Follow instructions for mounting to work- bench, substituting a board 18" x 24" mini- mum size and using 5t16 inch flat head

screws, Iockwashers, and hex nuts (not in- cluded). Screw length should be 11/2" plus the thickness of the mounting board.

NOTE: For proper stability, holes must be counter sunk so screw heads are flush with the

bottom surface of supporting board.

2, Securely clamp board to workbench using

"C" clamps.

NOTE: Supporting surface where belt and disc sander is mounted should be examined carefully

after mounting to insure that no movement dur-

ing use can result. If any tipping or walking is noted, secure workbench or supporting surface before operating belt and disc sander.

CLAMPING BELT AND DISC SANDER TO

WORKBENCH

The Belt and Disc Sander can be clamped direct-

ly to a workbench using two (2) or more "C"

clamps on base of unit (one clamp on each end

of unit).
