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.

MAINTENANCE

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.
