MAINTAINING YOUR TABLE SAW

GENERAL MAINTENANCE

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.

!.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.

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 ANDTILTING 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) should be adjusted as follows:

1.Using a 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 4 mm.

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.
