Installing or removing depressed center 
wheel or flap disc (optional accessory) 

WARNING: 

• 

When using a depressed center wheel or flap disc, the 
wheel guard must be fitted on the tool so that the closed 
side of the guard always points toward the operator. 

• 

Only actuate the shaft lock when the spindle is not 
moving.

To tighten the lock nut, press the shaft lock firmly so that 
the spindle cannot revolve, then use the lock nut wrench 
and securely tighten clockwise. 
To remove the wheel, follow the installation procedure in 
reverse.

CAUTION: 

• 

Do not use Ezynut with Super Flange or angle 
grinder with “F” on the end of the model No. Those 
flanges are so thick that the entire thread cannot 
be retained by the spindle.

OPERATION 

WARNING: 

• 

It should never be necessary to force the tool. The 
weight of the tool applies adequate pressure. 
Forcing and excessive pressure could cause 
dangerous wheel breakage. 

• 

ALWAYS replace wheel if tool is dropped while 
grinding. 

• 

NEVER bang or hit grinding disc or wheel onto 
work. 

• 

Avoid bouncing and snagging the wheel, 
especially when working corners, sharp edges etc. 
This can cause loss of control and kickback. 

• 

NEVER use tool with wood cutting blades and 
other sawblades. Such blades when used on a 
grinder frequently kick and cause loss of control 
leading to personal injury. 

CAUTION: 

• 

Never switch on the tool when it is in contact with 
the workpiece, it may cause an injury to operator.
