USE THE RIGHT TOOL. Don’t force tool or attachment to do a 
job it was not designed to do.  
 
CAUTION: This machine is not designed for heavy deburring    
operations. When finishing metals, sparks or hot fragments 
could cause a fire. To avoid this:  
 
• Disconnect any dust collecting hose from the sander.  
 
• Remove all traces of wood dust from the sander.  
 
• Remove all traces of metal dust from the sander before      
sanding wood again. 

 

WARNING!

 The Belt and Disc Sander with Built-in Dust Collector 

(model KC-790FX-DC) should not be used for any metal sanding 
operations. Hot metal and sparks generated by sanding metal will 
increase the risk of serious fire and/or damage to the dust collector 
system. Metal sanding should be performed using a Metal Sander 
connected to a Metal Dust Collector. 
 
Any power sanders can throw foreign object into eyes. This can 
cause permanent eye damage. Everyday eyeglasses have only 
impact resistant lenses. They are not safety glasses. Safety glasses 
are available.  
 
• Do not wear loose clothing, gloves, neckties or jewelry (rings, wrist, 
watches). They can get caught and draw your fingers into moving 
parts. 
 
• Wear nonslip footwear. 
 
• Tie back long hair.  
 
• Roll long sleeve above the elbow. 
 
• Noise levels vary widely. To avoid possible hearing damage, wear 

ear plugs or muffs when using sander for hours at a time.  

 
•  Sanding operations are usually dusty. Wear a dust mask along with 

the safety glasses. 

 
INSPECT YOUR WORKPIECE. 
Make sure there are no nails or foreign objects in the part of the       
workpiece to be sanded. 
 
Plan your work to avoid THROWBACKS - when the workpiece         
catches on the sanding belt or disc and torn from your hands.  
 
• Make sure there’s no debris between the workpiece and its          

  supports.

 

 
•  When sanding irregularly shaped workpieces, plan your work        

support so it will not slip and be pulled from your hands.

  

 
• Use extra caution with large, very small or awkward workpieces. 
 
• Never use this tool to finish pieces too small to hold by hand. 
 

• Use extra supports (tables, saw horses, blocks etc.) for any          

workpieces large enough to tip when not held down to the table 
top. 

 
• NEVER use another person as a substitute for a table extension, or 

as additional support for a workpiece that is longer or wider than 
the basic sander table, or to help feed, support, or pull the        
workpiece. 

 
• When finishing on the disc, always press the workpiece againt the 

“Down” side of the disc. Sanding against the side coming up from 
under the table could damage the work by making it chatter, or tear 
the work from your hands and throw it. 

 
• Sand only one workpiece at a time. 
 
• Clear everything except the workpiece and related support devices 

off the table before turning the sander on.  

 
• Plan the way you will hold the worpiece from start to finish. 
 
• Avoid awkward operations and hand positions where a sudden slip 
could cause fingers or hand to move into a sanding surface. Keep the 
fingers away from where the belt goes into the dust trap. 
 
WHENEVER SANDER IS RUNNING 
 
WARNING: Don’t let familliarity (gained from frequent use of your belt 
and disc sander) cause a careless mistake. A careless fraction of a        
second is enough to cause a severe injury. Before starting your work, 
watch the sander while it runs. If it makes an unfamilliar noise or 
vibrates a lot, stop immediately. Turn the sander off. Unplug the 
sander. Do not restart until finding and correcting the problem. Make 
sure the sanding disc turns counterclockwise before using the sander.  
 
KEEP CHILDREN AWAY. Keep all visitors a safe distance from the 
sander. Make sure bystanders are clear of the sander and workpiece.  
 
DON’T FORCE TOOL. It will do better and safer job at its designed 
rate. Press the workpiece against the sanding material only hard 
enough to let it sand without bogging down or binding. 

 
Before freeing any jammed material: 

• Turn switch "OFF" 
• Unplug the sander.  
• Wait for all moving parts to stop. 

 
BEFORE LEAVING THE SANDER: 

NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER 
OFF. Don' t leave until it comes to a complete stop. 
 
MAKE WORKSHOP CHILD-PROOF. Lock the shop. Disconnect     
master switches. Remove the yellow switch key. Store it away from 

children and others not qualified to use the tool.
