SERVICE SAFETY

1.  

If any part of this tool is missing or should break, bend, or fail in any way; 

     or should any electrical component fail to perform properly: SHUT OFF

 the 

     power switch and remove the tool’s plug from the power source and have the

     missing, damaged or failed parts replaced 

BEFORE

 resuming operation.

2.  

Tool service must be performed only at a Sears Service Center. 

Service or 

     maintenance performed by unqualified personnel could result in a risk of injury.
3.  

When servicing a tool, use only identical replacement parts. Follow 

     instructions in the maintenance section of this manual.  

Use of unauthorized 

     parts or failure to follow maintenance instructions may create a risk of 

     electric shock or injury.

SAFETY RULES FOR POWER SANDERS

1. 

HOLD TOOL by insulated gripping surfaces

 when sanding where tool may contact

    hidden wiring, such as walls, floors, or its own power cord.  Contact with a “live” wire will  

    make exposed metals parts of the tool “live” and shock the operator.
2. 

INSPECT FOR AND REMOVE 

all nails, screws, staples or any embedded pieces

    of metal from surface to be sanded. These protrusions could damage the sandpaper, 

    the cushion of the sander and cause loss of control.  Following this rule will reduce the 

    risk of serious personal injury and damage to the sander.
3. 

NEVER use this or any power sander for wet sanding or liquid polishing.  

 

   Failure to follow this rule will increase the risk of electric shock.

4. 

ALWAYS clamp the workpiece

 securely so it will not move under the sander. 

    Unsecured work could be thrown towards the operator, causing injury. 
5. 

DO NOT force the sander. 

The weight of the sander supplies adequate 

    pressure. Let the sander and the grit on the sandpaper do the work. 
6. 

DO NOT sand in any one place for too long. 

The sander’s rapid action may 

    remove too much material and make the surface uneven.

SAFETY INSTRUCTIONS cont.

WARNING: 

Check extension cords before each use. If damaged replace 

 immediately. Never use tool with a damaged cord since touching the damaged 

 area could cause electrical shock, resulting in serious injury.

!

EXTENSION CORDS

Use a proper extension cord. ONLY

 use cords listed by Underwriters Laboratories (UL).  

Other extension cords can cause a drop in line voltage, resulting in a loss of power and 

overheating of tool. For this tool an AWG (American Wire Gauge) size of a least 14-gauge 

is recommended for an extension cord of 25 - ft. or less in length. Use 12 -gauge for an 

extension cord of 50 -ft. 

Extension cords 100-ft. or longer are not recommended.

 

Remember, 

a smaller wire gauge size has greater capacity than a larger number

 

(14 - gauge wire has more capacity than 16-gauge wire; 12-gauge wire has more capacity 

than 14 - gauge). When in doubt use the smaller number. When operating a power tool 

outdoors, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for 

outdoor use and reduce the risk of electric shock.

!

      

CAUTION: 

Keep the extension cord clear of the working area. 

 Position the cord so that it will not get caught on lumber, tools or other 

 obstructions while you are working with a power tool. 

3. 

BEFORE

 plugging in the tool, 

BE SURE

 that the outlet voltage supplied is within the 

    voltage marked on the tool’s data plate. 

DO NOT

 use “AC only” rated tools with 

    a DC power supply.
4. 

AVOID body contact with grounded surfaces

, such as pipes, radiators, ranges and 

    refrigerators. There is an increased risk of electric shock if your body is grounded.
5. 

DO NOT expose power tools to rain or wet conditions or use power tools in wet 

    or damp locations.

 Water entering a power tool will increase the risk of electric shock.

6.

 INSPECT tool cords for damage.

 Have damaged tool cords repaired at a 

Sears 

    Service Center

BE SURE

 to stay constantly aware of the cord location and keep it well 

    away from moving parts.
7. 

DO NOT abuse the cord. NEVER use the cord to carry the tool by or to pull the 

    plug from the outlet

. Keep cord away from heat, oil, sharp edges or moving parts. 

    Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

      

WARNING: 

Double insulation DOES NOT take the place of normal safety 

 precautions when operating this tool.

!

ELECTRICAL SAFETY 

2. Double insulation      eliminates the need for the three-wire grounded power cord and 

    grounded power supply system. Applicable only to Class II (double-insulated) tools. 

    This tool is a double insulated tool.
