 To avoid mistakes that could cause serious, permanent 

injury, do not plug sander in until the following is understand. 
 
• Assembly and alignment.  
 
• Learn the use and function of the ON-OFF switch, belt tracking 

knob, work tables and work table tilt lock knobs.

procedures in this manual.  

 
• Review of the maintenance methods for this sander.  
 

WHEN INSTALLING OR MOVING THE SANDER 
 
AVOID DANGEROUS ENVIRONMENT

. Use the sander in a dry, 

indoor place protected from rain. Keep work area well lighted. Place 
the sander so neither the user nor bystander are forced to stand in 
line with the abrasive belt or disc. 
 
To avoid injury from unexpected sander movement: 
 
• Always unplug the sander before moving it. 

 
• Put the sander on a firm level surface where there is plenty of room 

for handing and properly supporting the workpiece. 

 
• Support the sander so it does not rock.  
 
• Bolt the sander to its work surface.  
 

 NEVER STAND ON TOOL

. Serious injury could occur if the tool 

tips. Do not store anything above or near the tool where anyone 
might stand on the tool to reach them. 

 

BEFORE EACH USE: 
 
Inspect your sander.

 

DISCONNECT THE SANDER. To avoid injury from accidental     
starting, unplug  the sander, turn the switch off before changing the 
setup, sanding disc or belt or adjusting anything.  
 
CHECK DAMAGED PARTS, check for: 
• alignment of moving parts 
 
• binding of moving parts 
 
• broken parts 

 
• work parts that cause a gap larger than 1/16’’ between work       

support and sanding surface. 

 

• sanding belt narrower than 1 inches. Narrower belts uncover parts 

that could trap your fingers. 

 
• worn or damaged electric cords. 

 
• stable mounting, and any other conditions that may affect the way 

the sander works. 

 
If any part is missing, bent, or broken in any way, or any electrical 
parts don’t work properly, turn the sander off and unplug the sander. 
REPLACE damaged, missing or failed parts before using the sander 
again. 
 
MAINTAIN TOOLS WITH CARE. Keep the sander clean for best and 
safest performance. Follow instruction for lubricating. 
REMOVE ADJUSTING KEYS AND WRENCHES from tool before 
turning it on.      

 
To avoid injury from jams, slips or thrown pieces: 

• USE ONLY RECOMMENDED ACCESSORIES. The use of      

improper accessories may cause risk of injury to person. 

 
• Adjust any work support to clear the sanding surface by no more 

1/16”.   

 
• Make sure all clamps and locks are tight and no parts have          

excessive play. 

 
• KEEP WORK AREA CLEAN. Cluttered areas and benches invite 

accidents. Floor must not be slippery. 

 
To avoid burns or other fire damage, never use the sander near       
flammable liquids, vapors or gases.  
 
PLAN AHEAD TO PROTECT YOUR EYES, HANDS, FACE, EARS. 
KNOW YOUR SANDER. Read and understand the instruction          
manual and labels affixed to the tool. Learn its application and           
limitations as well as the specific potential hazards related to it. 
 

To avoid injury from accidental contact with moving parts:

 

 
• KEEP GUARD IN PLACE and in working order. 
 
• Don’t do layout, assembly, or setup work on the sander while any 

parts are moving. 

 
• AVOID ACCIDENTAL STARTING. Make sure switch is “OFF” 

before plugging sander into a power outlet. 

 
Plan your work.
