Mounting and Using Cutting (Type 1) Wheels

Cutting wheels include diamond wheels and abrasive discs. Abrasive cutting wheels for metal and concrete use are available. Diamond blades for concrete cutting can also be used.

WARNING: A closed, 2-sided cutting wheel guard is not included with this tool but is required when using cutting wheels. Failure to use proper flange and guard can result in injury resulting from wheel breakage and wheel contact. See page 7 for more information.

MOUNTING CLOSED (TYPE 1) GUARD

CAUTION: Turn off and unplug the tool before making any adjustments or removing or installing attachments or acces- sories. Before reconnecting the tool, turn the switch on and off as previously described to ensure that the tool is off.

the lugs (N) on the guard with the
slots (O) on the gear case.

2. Push the guard down until the
guard lug engages and rotates	N
freely in the groove on the gear
case hub.

3. Rotate guard (I) into desired	M
working position. The guard body
should be positioned between the
spindle and the operator to provide
maximum operator protection.
4. Close the guard latch to secure the guard
on the gear case cover. You should be
unable to rotate the guard by hand when	I
the latch is in closed position. If rotation is
