5. 

Do not attach a saw chain woodcarving blade 
or toothed saw blade.

 Such blades create 

frequent kickback and loss of control. 

6. 

Do not "jam" the wheel or apply excessive 
pressure. Do not attempt to make an 
excessive depth of cut.

 Overstressing the wheel 

increases the loading and susceptibility to twisting 
or binding of the wheel in the cut and the possibility 
of kickback or wheel breakage. 

7. 

When wheel is binding or when interrupting a 
cut for any reason, switch off the power tool 
and hold the power tool motionless until the 
wheel comes to a complete stop. Never 
attempt to remove the wheel from the cut 
while the wheel is in motion otherwise 
kickback may occur.

 Investigate and take 

corrective action to eliminate the cause of wheel 
binding. 

8. 

Do not restart the cutting operation in the 
workpiece. Let the wheel reach full speed and 
carefully reenter the cut.

 The wheel may bind, 

walk up or kickback if the power tool is restarted in 
the workpiece. 

9. 

Support panels or any oversized workpiece to 
minimize the risk of wheel pinching and 
kickback.

 Large workpieces tend to sag under 

their own weight. Supports must be placed under 
the workpiece near the line of cut and near the 
edge of the workpiece on both sides of the wheel. 

10. 

Use extra caution when making a "pocket cut" 
into existing walls or other blind areas.

 The 

protruding wheel may cut gas or water pipes, 
electrical wiring or objects that can cause 
kickback. 

SAVE THESE INSTRUCTIONS.
