without a guard only when sanding with conventional
sanding discs. Refer to Figure A to see guards provided
with the unit. Some applications may require purchasing
the correct guard from your local dealer or authorized
servicecentre.
NOTE: Edge grinding and cutting can be performed with Type
27wheels designed and specified for this purpose; 6.35 mm
thick wheels are designed for surface grinding while thinner
Type 27wheels need to be examined for the manufacturer's
label to see if they can be used for surface grinding or only
edge grinding/cutting. A Type 1guard must be used for any
wheel where surface grinding is forbidden. Cutting can also be
performed by using a Type41wheel and a Type 1guard.
NOTE: See the Accessory Chart to select the proper guard /
accessorycombination.
Mounting and Adjusting the One‑Touch

Guard (Fig. D)

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can causeinjury.
Adjusting the Guard
For guard adjustment, the guard release lever
8
engages
one of the alignment holes
14
on the guard collar using a
ratchetingfeature.
The engaging face is slanted and will ride over to the
next alignment hole when guard is rotated in a clockwise
direction (spindle facing user) but self‑locks in the
anti‑clockwisedirection.
Mounting the Guard (Fig.D)
1. Press the guard release lever
8
.
2. While holding the guard release lever open, align the
lugs
12
on the guard with the slots
13
on the gearcase.
3. Keeping the guard release lever open, push the guard down
until the guard lugs engage and rotate them in the groove
on the gear case hub. Release the guard releaselever.
4. With the spindle facing the operator, rotate the guard
clockwise into the desired working position. Press and
hold the guard release lever
8
to rotate the guard in the
anti‑clockwisedirection.
NOTE: The guard body should be positioned between
the spindle and the operator to provide maximum
operatorprotection.
The guard release lever should snap into one of the
alignment holes
14
on the guard collar. This ensures that
the guard issecure.
5. To remove the guard, follow steps 1–3 of these instructions
inreverse.


WARNING: A closed, two‑sided cutting wheel guard is
re quired when using cutting wheels.

WARNING: Use of a damaged flange or guard or fail ure

Mounting Sanding Backing Pads (Fig. A, F)
NOTE: Use of a guard with sanding discs that use backing pads,
often called fiber resin discs, is not required. Since a guard is
not required for these accessories, the guard may or may not fit
correctly ifused.

WARNING: Failure to properly seat the flange/ clamp nut/
wheel could result in serious injury (or damage to the tool
orwheel).

WARNING: Proper guard must be reinstalled for grinding
wheel, cutting wheel, sanding flap disc, wire brush or
wire wheel applications after sanding applications
