Safety is a combination of common sense, staying alert and knowing how your item works. 

SAVE THESE SAFETY INSTRUCTIONS. 

 
1. READ and become familiar with this entire instruction manual. LEARN the tool’s applications, limitations, and 
possible hazards. 

AVOID DANGEROUS CONDITIONS

2. DO NOT use power tools in wet or damp areas or expose them to rain. 

3. DO NOT use power tools in the presence of flammable liquids or gases. 

4. ALWAYS keep your work area clean, uncluttered, and well lit. DO NOT work on floor surfaces that are slippery 
with sawdust or wax. 

5. CHILDPROOF THE WORKSHOP. Use padlocks and master switches and ALWAYS remove starter keys 
on all tools. 

6. KEEP BYSTANDERS AT A SAFE DISTANCE from the work area, especially when the tool is operating. 
NEVER allow children or pets near the tool. 

DRESS FOR SAFETY

7. DO NOT wear loose clothing, gloves, neckties, or jewelry (rings, watches, etc.) When operating the tool. Inap-
propriate clothing and items can get caught in moving parts and draw you in. ALWAYS wear non-slip footwear and 
tie back long hair. 

8. USE SAFETY GOGGLES AT ALL TIMES that comply with ANSI Z87.1. Normal safety glasses only have 
impact resistant lenses and are not designed for safety. Use ear protection such as plugs or muffs during extended 
periods of operation.

9. WEAR A FACE MASK OR DUST MASK to fight the dust produced by sanding operations. 

OPERATE WITH PRECAUTIONS

10. STAY ALERT. A moments of inattention when operating power tools may result in serious personal injury. 
DO NOT operate the tool if you are tired or under the influence of drugs, alcohol, or medication that may affect 
your ability to properly use the tool. 

11.  CHECK  FOR  DAMAGED  PARTS.  Check  for  alignment  of  moving  parts,  jamming,  breakage,  improper 
mounting, or any other conditions that may affect the tool’s operation. Any part that is damaged should be properly 
repaired or replaced before use.
