OPERATION

WARNING:
• It should never be necessary to force the tool.
The weight of the tool applies adequate pres-
sure. 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, espe-
cially 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.
