complete stop. Never attempt to remove the unit from the work or pull the unit 

backward while the wheel is in motion or kickback may occur.

 Investigate and 

take corrective actions to eliminate the cause of wheel binding.

 •  

When restarting a cut-off tool in the workpiece, check that the wheel is not 

engaged into the material.

 If wheel is binding, it may walk up or kickback from 

the workpiece as the tool is restarted.

 •  

Support large panels to minimize the risk of wheel pinching and kickback. 

Large panels tend to sag under their own weight. Support must be placed under 

the panel on both sides, near the line of cut and near the edge of the panel.

WARNING: ALWAYS 

use safety glasses. Everyday eyeglasses are NOT safety 

glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR 

CERTIFIED SAFETY EQUIPMENT:

•  ANSI Z87.1 eye protection (CAN/CSA Z94.3),
•  ANSI S12.6 (S3.19) hearing protection,
•  NIOSH/OSHA/MSHA respiratory protection.

WARNING: 

Some dust created by power sanding, sawing, grinding, drilling, and 

other construction activities contains chemicals known to cause cancer, birth defects 

or other reproductive harm. Some examples of these chemicals are:

•  lead from lead-based paints,
•  crystalline silica from bricks and cement and other masonry products, and 
•  arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do this type of 

work. To reduce your exposure to these chemicals: work in a well ventilated area, and 

work with approved safety equipment, such as those dust masks that are specially 

designed to filter out microscopic particles.
  •

  Avoid prolonged contact with dust from power sanding, sawing, grinding, 

drilling, and other construction activities. Wear protective clothing and wash 

exposed areas with soap and water. 

Allowing dust to get into your mouth, eyes, 

or lay on the skin may promote absorption of harmful chemicals. 

WARNING: 

Use of this tool can generate and/or disburse dust, which may cause 

serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved 

respiratory protection appropriate for the dust exposure. Direct particles away from 

face and body.
