MAINTENANCE

MAINTAINING YOUR TABLE SAW

GENERAL MAINTENANCE

AWARDING

For your own safety, turn the switch OFF and remove the

switch key. Flemove the plug from the power source outlet

before maintaining or lubricating your saw.

1. Clean out all sawdust that has accumulated inside

the saw cabinet and the motor.

2.

Polish the saw table with an automotive wax to keep
it clean and to make it easier to slide the workpiece.

3.

Clean cutting blades with pitch and gum remover.

4.

A worn, cut, or damaged power cord should be

replaced immediately.

A WARNING

All electrical or mechanical repairs should be attempted
only by a trained repair technician. Contact the nearest
Sears Service Center for service. Use only identical

replacement parts. Any other parts may create a hazard.

5.

Use liquid dish washing detergent and water to

clean all plastic parts.

NOTE:

Certain cleaning chemicals can damage

plastic parts.

6.

Avoid use of the following cleaning chemicals or

solvents: gasoline, carbon tetrachloride, chlorinated
solvents, ammonia and household detergents
containing ammonia.

BLADE RAISING AND TILTING MECHANISM (FIG. GG)

After each five hours of operation, the blade raising

mechanism and tilting mechanism should be checked for
looseness, binding, or other abnormalities. With the saw

disconnected from the power source, turn the saw

upside down and alternately pull upward and downward

on the motor unit. Observe any movement of the motor

mounting mechanism. Looseness or play in the blade
raising screw (1) shouid be adjusted as follows:

1.

Using a wrench, ioosen nut (2).

2.

Adjust nut (3) until it is finger-tight against the

bracket (4), then back off the nut (3) 1/6 turn.

3.

Tighten nut (2) with the wrench, while holding nut (3)

in place. Maximum allowable play of screw rod (1)
is 4 mm.

Fig. GG

Place a small amount of dry lubricant such as graphite

or silicon on screw rod (1) at thrust washer (5). Do not
oil threads of screw rods (1). Screw rod (1) must be
kept clean and free of sawdust, gum, pitch, and other
contaminants for smooth operation.

If excessive looseness is observed in any other part of the

blade raising mechanism or tilting mechanism, take the

complete unit to a Sears Service Center.

LUBRICATION

All motor bearings are permanently lubricated at the
factory and require no additional lubrication.
On all mechanical parts of your table saw where a

pivot or threaded rod are present, lubricate using
graphite or silicone. These dry lubricants will not
hold sawdust as would oil or grease.
