Periodic maintenance allows for long life and trouble-free operation. A cleaning and 

maintenance schedule should be maintained. As a common preventive maintenance 

practice, follow these recommended steps:

 1.  When work has been completed, clean the tool to allow smooth functioning of the tool 

      over time. Clean the tool with compressed air.
 2.  Use clean damp cloths to wipe the tool.
 3.  Keep the motor air openings free from oil, grease and sawdust or woodchips, and store 

      tool in a dry place.

WARNING: 

DO NOT at any time let brake fluids, gasoline, petroleum-

 based products, penetrating oils, etc. come in contact with plastic parts. 

 Chemicals can damage, weaken or destroy plastic, which may result in serious 

 personal injury.

!

WARNING: 

For your safety, ALWAYS turn off switch and unplug sander 

 from the power source before performing any maintenance or cleaning.

ROUTINE MAINTENANCE

LUBRICATION

Your Craftsman

®

 Professional Pad Sander has been properly lubricated and is ready to use. 

No further lubrication is needed under normal operating conditions. All bearings in the 

sander are lubricated for the life of the tool.

MAINTENANCE

It has been found that electric tools are subject to accelerated wear and possible 

premature failure when they are used to work on fiber glass boats and sports cars, 

wallboard, spackling compounds or plaster. The chips and grindings from these materials 

are highly abrasive to electrical tool parts, such as bearings, brushes, commutators, etc. 

Consequently, it is not recommended that this tool be used for extended work on any 

fiberglass material, wallboard, spackling compound or plaster. During any use on these 

materials, it is extremely important that the tool is cleaned frequently by blowing with 

an air jet.

!

WARNING: 

To ensure safety and reliability, repairs, maintenance and 

 adjustments MUST be performed by a qualified service technician at a 

 Sears Service Center.

!

WARNING: 

For your safety, ALWAYS turn off switch and unplug sander 

 from the power source before performing any maintenance or cleaning.

!

WARNING: 

Always wear safety goggles or safety glasses with side shields 

 during power tool operations, or when blowing dust. If operation is dusty, also 

 wear a dust mask.

REMOVE PRESSURE-SENSITIVE SANDPAPER BEFORE STORAGE
DO NOT

 store your sander with pressure-sensitive sandpaper still attached. The heat 

generated by sanding causes the pressure-sensitive adhesive to flow and form a tight 

bond between the cushion and the sandpaper.

ALWAYS 

remove the sandpaper soon after you have finished sanding to avoid adhesive set 

up. When sandpaper is left on the cushion for an extended period of time after use, the 

adhesive will set up and make the sandpaper difficult to remove.
The sandpaper may tear when removing it. If this happens it makes it difficult to clean the 

cushion for the next piece of sandpaper.

NOTE: If you do forget to remove the sandpaper after sanding, run your sander for 

a few minutes to soften the adhesive backing before you try to remove the sandpaper.

OPERATION cont.

FLUSH SANDING (See Fig. 11)

Your sander will allow you to flush sand corners. 

You can use the front and sides of your sander for flush sanding. 

DO NOT

 use the rear 

of the sander for flush sanding. 

ALWAYS

 remove the sander from the workpiece before turning it off.
