concrete or masonry, there is an increased risk of exposure
to dust and loss of control resulting in kickback.
nOTE: Edge grinding and cutting can be performed with Type
27 wheels designed and specified for this purpose; 6 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 A (cut‑off) wheel guard must be used for any
wheel where surface grinding is forbidden. A Type A (cut‑off)
(previously called type 1/41) wheel guard must be used for for
any dual purpose (combined grinding and cutting‑off abrasive)
wheels. Cutting can also be performed by using a Type 1/41
wheel and a Type A cut‑off wheel guard previously called Type
1/41 guard.
nOTE: See the Accessory and Guard Applications Chart to
select the proper guard / accessory combination.
Mounting and Removing Guard (Fig. F)
CAUTION: Guards must be used with all grinding wheels,
cut‑off wheels, diamond coated wheels, sanding flap
discs, wire brushes, and wire wheels. The tool may be used
without a guard only when sanding with conventional
sanding discs. Some D
guard intended for use with depressed centre wheels (Type
27) and hubbed grinding wheels (Type 27). The same
guard is designed for use with sanding flap discs (Type
27 and 29) and wire brushes. A Type A guard must be used
for any cutting application. Grinding with wheels other
than Type 27 and 29 require different accessory guards.
Mounting instructions for these accessory guards are
included in the accessory package.
1. Open the guard release lever
guard with the slots

2. Push the guard down until the guard lugs engage and
rotate freely in the groove on the gear case hub.
3. With the guard latch open, rotate the guard
desired 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.
You should not be able to rotate the guard by hand when
the latch is closed. Do not operate the grinder with a loose
guard or the clamp lever in open position.
5. To remove the guard, open the guard latch, rotate the guard
so that the arrows are aligned and pull up on the guard.
nOTE: The guard is pre‑adjusted to the diameter of the gear
case hub at the factory. If, after a period of time, the guard
becomes loose, tighten the adjusting screw
lever in the closed position.
CAUTION: Do not tighten the adjusting screw with the
clamp lever in open position. Undetectable damage to the
guard or the mounting hub may result.
CAUTION: If guard cannot be tightened by adjusting
clamp, do not use tool and take the tool and guard to a
service centre to repair or replace the guard.

injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
can cause injury.
Mounting Non‑Hubbed Wheels (Fig. G)
WARNING: Failure to properly seat the flanges and/or
wheel could result in serious injury (or damage to the tool
or wheel).
CAUTION: Included flanges must be used with depressed
centre Type 27/42 grinding wheels and Type 1/41 cutting
wheels. Refer to the Accessory and Guard Applications
Chart for more information.
WARNING: A closed, two‑sided cutting wheel guard is
required when using abrasive cutting wheels or diamond
coated cutting wheels, referred to as a Type A cut‑off
wheel guard.
WARNING: Use of a damaged flange or guard or fail‑
ure to use proper flange and guard can re sult in injury
due to wheel breakage and wheel contact. Refer to
the Accessory and Guard Applications Chart for
more information.

Mounting Sanding Backing Pads (Fig. A, H)
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 clamp nut and/
or pad 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
are complete.
