replaced immediately.

attempted only by a trained repair technician.
Contact the nearest Sears Service Center for

solvents, ammonia and household detergents

BLADE RAISING AND TILTING MECHANISM
(FIG. LL)
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 aiternately 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), and 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 in. (4 mm).
Place a small amount of dry lubricant on height
regulating bolt (1). This must be kept dean 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 iubricated 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.
