  WARNING 

 

Wear eye protection. 

Always keep guards in place and in proper operating condition.  Do not operate the machine 

without the guards for any reason. 

This sander is intended to be used with wood and wood products only.  Use of this sander and a 

dust collector with metal products is a potential fire hazard. 

Support the workpiece adequately at all times during operation; maintain control of the work at all 

times. 

 

This drum sander is designed and intended for use by properly trained and experienced 

personnel only.  If you are not familiar with the proper and safe operation of a drum sander, do not 

use until proper training and knowledge has been obtained. 

 

• 

REMOVE ADJUSTING KEYS AND WRENCHES.  Form a habit of checking to see that keys and 
adjusting wrenches are removed from the machine before turning it on. 

 

• 

KEEP THE WORK AREA CLEAN.  Cluttered areas and benches invite accidents. 

 

• 

DON’T USE IN A DANGEROUS ENVIRONMENT.  Don’t use power tools in damp or wet locations, 
or expose them to rain.  Keep work area well lighted. 

 

• 

KEEP CHILDREN AWAY.  All visitors should be kept a safe distance from the work area. 

 

• 

MAKE THE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys. 

 

• 

DON’T FORCE THE MACHINE.  It will do the job better and safer at the rate for which it was 
designed. 

 

• 

USE THE RIGHT TOOL.  Don’t force a machine or attachment to do a job for which it was not 
designed. 

 

• 

USE THE PROPER EXTENSION CORD.  Make sure your extension cord is in good condition.  When 
using an extension cord, be sure to use one heavy enough to carry the current your machine will 
draw.  An undersized cord will cause a drop in the line voltage resulting in power loss and 
overheating. The table following shows the correct size to use depending on the cord length and 
nameplate ampere rating.  If in doubt, use the next heavier gauge.  Remember, the smaller the gauge 
number, the heavier the cord.

• 

WEAR PROPER APPAREL.  Do not wear loose clothing, gloves, neckties, rings, bracelets, or other 
jewelry which may get caught in moving parts.  Nonslip footwear is recommended.  Wear protective 
hair covering to contain long hair. 

 

• 

ALWAYS USE SAFETY GLASSES.  Also use face or dust masks if the cutting operation is dusty.  
Everyday eyeglasses only have impact resistant lenses; they are not safety glasses. 

 

• 

DON’T OVERREACH.  Keep proper footing and balance at all times. 

 

• 

MAINTAIN TOOLS WITH CARE.  Keep tools sharp and clean for best and safest performance.  
Follow instructions for lubricating and changing accessories.
