MAINTENANCE

MAINTAINING YOUR TABLE SAW

Fig. EE

GENERAL MA

WARNING

NTENANCE

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

switch key. Remove the plug from the power source outlet

before maintaining or lubricating your saw.

1. Clean out ail 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.

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, ammonia and household detergents
containing ammonia.

BLADE RAISING AND TILTING MECHANISM (FIG. EE)

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

dis-connected from the power source, turn the saw upside
down and alternately pull upward and downward on the

motor unit. Cbserve any movement of the motor mounting
mechanism. Looseness or play in the blade raising screw
(1) should be adjusted as follows:

1. Using a 14mm wrench, loosen 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

0.16” (4 mm).

Place a small amount of dry lubricant on bevel gear (2).
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 parts 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 ail 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.
