For replacement motor refer to parts list is this manual.

specifications and electrica requirementsThis plug requires a mating 3-conductor grounded typeoutlet as shown.

CONNECTING TO POWER SUPPLY OUTLET

This machine must be grounded while in use to protectthe oeprator from electric shock.

Plug power cord into a 110-120V properly groundedtype outlet protected by a 15-amp. fuse or circuitbreaker.

If the outlet you are planning to use for this power toolis of the two prong type, DO NOT REMOVE OR ALTERTHE GROUNDING PRONG IN ANY MANNER. Usean adapter as shown below and always connect thegrounding lug to a known ground.

It is recommended that you have a qualified electricianreplace the TWO prong outlet with a properly groundedTHREE prong outlet.

WARNING: Do not permit fingers to touch the ter-minals of plugs when installing or removing theplug to or from the outlet.

WARNING: If not properly grounded this powertool can cause an electrical shock, particularlywhen used in damp locations close to plumbing. Ifan electrical shock occurs there is the potential ofa secondary hazard such as your hands contactingthe sanding surface.

If power cord is worn or cut, or damaged in any way,have it replaced immediately.

If your unit is for use on 110-120 volts, and has a plugthat looks like below.

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 Elec*tricaf Code.

MOUNTING BELT AND DISC SANDERTO WORKBENCH

If belt and disc sander is to be used in a permanentlocation, it should be fastened securely to a firm sup-porting surface such as a workbench. A 5/16" bolt, flat-washer, Iockwasher, and hex nut (not included) shouldbe used at each mounting hole to secure the belt discsander to the workbench.

If mounting to a workbench, holes should be drilledthrough supporting surface of the workbench as follows:

1. Set the belt disc sander on the workbench in the

exact position where it is to be mounted,

2, Push a pencil through one of the mounting holesand place a mark on the workbench that marks thecenter of the mounting hole opening. Mark the otherthree mounting hotes using the same method.

SPECIAL NOTE: Make sure the pencil marks areplaced very near the center of the mounting holeopenings,

WARNING: Check under workbench before drillingholes to make sure electrical wires, gas pipes, etc.,will not be hit by drill bit.

3. Remove the belt disc sander from the workbench.

Drill four 3/8" diameter holes using the pencil marksas the center of the drilled holes.

SPECIAL NOTE: It is highly recommended that youplace a soft foam pad between your belt disc sanderand workbench. The use of this pad will reduce noiseand vibration.

4. Place the belt disc sander back on the workbench.Align the mounting holes in the sander with thedrilled holes in the workbench.

MOUNTING HOLES

.

6,

Insert four 5/16" bolts through the mounting holesand through the dritled holes in the workbench.

Place a 5/16" flat washer, 5116" lockwasher, and a5/16" hex nut on the bolt and tighten,

SPECIAL NOTE: Do not overtighten mountingbolts - leave some cushion in the foam pad for ab-sorbing noise and vibration.

This leg setis an optional accessory and instructions to mountthe belt and disc sander to this leg set are includedin the leg set package.

ALTERNATE MOUNTING METHOD

An alternate method of mounting the belt and disc san-der is to fasten the sander to a mounting board. Theboard should be of sufficient size to avoid tipping ofsander while in use. Any good grade of plywood orch_pboard with a 3/4" minimum thickness is recom-mended. (Thinner chipboard can break.)

1, Follow instructions for mounting sander to work-bench, substituting a board 18" X 24" minimum sizein place of the workbench.
