WARNING: 

GRINDING/CUTTING/DRILLING OF MASONRY, CONCRETE, METAL AND OTHER MATERIALS CAN GENERATE DUST, 

MISTS AND FUMES CONTAINING CHEMICALS KNOWN TO CAUSE SERIOUS FATAL INJURY OR ILLNESS, SUCH AS RESPIRATORY 

DISEASE, CANCER, BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM.  IF YOU ARE UNFAMILIAR WITH THE RISKS ASSOCIATED 

WITH THE PARTICULAR MATERIAL BEING CUT, REVIEW THE MATERIAL SAFETY DATA SHEET AND/OR CONSULT YOU EMPLOYER, 

THE MATERIAL MANUFACTURER/SUPPLIER, GOVERNMENTAL AGENCIES SUCH AS OSHA AND NIOSH AND OTHER 

AUTHORITIES ON HAZARDOUS MATERIALS.  CALIFORNIA AND SOME OTHER AUTHORITIES, FOR INSTANCE, HAVE 

PUBLISHED LISTS OF SUBSTANCES KNOWN TO CAUSE CANCER, REPRODUCTIVE TOXICITY, OR OTHER HARMFUL 

EFFECTS.  CONTROL DUST, MIST AND FUMES AT THE SOURCE WHERE POSSIBLE.  IN THIS REGARD USE GOOD 

WORK PRACTICES AND FOLLOW THE RECOMMENDATIONS OF THE MANUFACTURER/SUPPLIER, OSHA/NIOSH, 

AND OCCUPATIONAL AND TRADE ASSOCIATIONS.  WHEN THE HAZARDS FROM INHALATION OF DUST, MISTS AND 

FUMES CANNOT BE ELIMINATED, THE OPERATOR AND ANY BYSTANDERS SHOULD ALWAYS WEAR A RESPIRATOR 

APPROVED BY OSHA/MSHA FOR THE MATERIAL BEING CUT.

Grinding

Beware of hidden obtrusions.  

Watch out for hidden dangers and protrusions in flooring. Do not 

use on largely uneven surfaces. 

Avoid contact with hot tooling and shroud.  

Do not touch the tooling or shroud without proper hand protection. 

Both become hot during operation and remain hot after stopping 

the machine. 

Use correct tooling and accessories.  

Provide barriers or shields as needed to protect others from debris. 

Use for correct applications. 

Do not force equipment to do heavier duty work than it was made 

for. 

Do not block the machine’s air flow. 

 

Blocking ventilation slots or air flow will result in damage to the 

machine. Leave space for air to flow freely during operation. 

Use dead man cable during operation.  

Loss of control of the grinder could cause damage, injury, or death.

Dust Collection 

Use with appropriate dust collecting system.  

Do not operate machine designed for use with a dust collector 

without the dust collector. Ensure dust collector is on and operating 

properly while grinding. 

Use with appropriate dust collection hose.  

Do not operate the machine without the hose securely attached to 

the inlet of the dust collector and the outlet of the grinder. In order 

to maintain system efficiency, do not use a damaged hose. 

Dispose of collected waste.  

Do not leave the dust collector bag full of waste. Handle and 

dispose of bag and waste in accordance with all applicable local, 

state, and federal regulations. Dispose of waste prior to transport.

Safety

Battery (Propane Machines Only)

Remove personal metal items when working with battery. 

A battery can produce a short circuit current sufficient enough to 

weld metal objects, causing severe burns. Be careful to not drop 

metal tools on the battery, as a spark or short circuit could cause 

an explosion.

Never smoke or allow a spark or flame near the battery.

WARNING:

 BE CAUTIOUS WHEN WORKING WITH 

BATTERY. IF ELECTROLYTIC  ACID GETS IN THE EYES, 

IMMEDIATELY FLUSH OUT WITH COLD, FRESH WATER 

FOR AT LEAST 10 MINUTES AND GET MEDICAL HELP.
