the guard must be securely attached 

1. 

to the power tool and positioned for 

maximum safety, so the least amount 

of wheel is exposed towards the 

operator. The guard helps to protect 

operator from broken wheel fragments 

and accidental contact with wheel.
do not “jam” the cut-off 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.
do not position your body in line 

3. 

with and behind the rotating wheel. 

When the wheel, at the point of 

operation, is moving away from your 

body, the possible kickback may propel 

the spinning wheel and the power tool 

directly at you.
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 cut-off 

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.
do not restart the cutting operation

kickback if the power tool is restarted in

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.
use extra caution when making a 

7. 

“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.

angle grinder manual at all times.
Use a cutting wheel/blade appropriate 

9. 

for the size of both the grinder and this 

guard.  Using a wheel/blade larger than 

the grinder is designed for causes safety 

problems, even if the guard can handle 

the wheel/blade.  (For example:  The 

body of a 4” grinder may be too short to 

keep your hands clear of a 4.5” wheel.)
Adjust depth and lock depth knobs

before use.

Hold onto grinder securely when finishing

a cut because it will have a tendency to 

snag the edge of the material.
Wear ANSI-approved safety glasses,

NIOSH-approved dust mask/respirator 

and hearing protection under full face 

shield along with heavy-duty work gloves 

and steel-toed work boots during use.
Keep bystanders and animals out of the

Keep work area clean and well lit.
