6 Before use

6.1 Inserting the battery 5
CAUTION
Check that the power tool is switched off and the
switch interlock activated before fitting the battery.
CAUTION
Before inserting the battery in the power tool, check
to ensure that the battery terminals and the contacts
in the power tool are free from foreign objects.
1. CAUTION If the battery is not fitted correctly
it may drop out and fall while the work is in
progress.
CAUTION A falling battery may present a risk of
injury to yourself and others.
Before beginning the work, check that the battery is
securely seated in the tool.
6.2 Removing the battery from the power tool 6
6.3 Transport and storage of batteries
CAUTION
Fire hazard. Never transport batteries in loose, bulk form.
There is a risk of short circuiting.
Pull the battery out of the locked position (working posi-
tion) and move it into the first latching position (transport
position).
Observe national and international transport regulations
when shipping batteries (transportation by road, rail, sea
or air).
6.4 Fitting the side handle
Screw the side handle into one of the threaded bushings
provided.
6.5 Guards
CAUTION
Wear gloves when fitting or removing parts, when
making adjustments or when remedying malfunc-
tions.
Read the instructions for fitting the corresponding guard.
6.5.1 Fitting the guard 7
NOTE
The guard is equipped with locating lugs that ensure only
guards of a type suitable for use with the power tool can
be fitted. The locating lugs of the guard fit into the guard
mount on the power tool.
1. Fit the guard onto the drive spindle collar so that the
two triangular marks on the guard and on the power
tool are in alignment.
2. Push the guard onto the drive spindle collar; press
the guard release button.
3. Rotate the guard until it engages and the guard
release button jumps back into its original position.
6.5.1.1 Adjusting the guard
Press the guard release button and then rotate the guard
until it engages in the desired position.
6.5.2 Removing the guard (hood)
Press the guard release button and remove the guard.
6.5.3 Fitting and removing the front cover 8
NOTE
If you use the front cover, fit it by pushing it onto the
guard.
1. Press the front cover onto the standard guard, with
the closed side positioned as shown in the illustra-
tion, until it engages.
2. To remove the front cover, release the catch and
then pull the front cover away from the standard
guard.
6.5.4 Positioning the DC‑EX 125⁄5" cutting guard 9
NOTE
Take care to ensure that the on / off switch is freely
accessible and operable at all times.
6.6 Fitting and removing discs
NOTE
Diamond discs must be replaced when the cutting or
grinding performance drops significantly. This generally
is the case when the diamond segments reach a height of
less than 2 mm (¹⁄₁₆"). Other discs must be replaced when
the cutting performance drops significantly or other parts
of the angle grinder (not the disc) come into contact with
the material you are working on. Abrasive discs generally
have to be replaced when the durability date has been
reached.
6.6.1 Fitting discs 10 11
WARNING
Tighten the disc and flange securely. If the nut securing
the disc and flange is not tightened firmly, the disc may
work loose from the spindle due to the braking effect of
the power tool's motor after switching off.
1. Remove the battery from the power tool.
2. CAUTION The clamping flange is equipped with
an O-ring. If this O-ring is missing, the clamping
flange must be replaced.
Fit the clamping flange onto the drive spindle (keyed
fit to prevent slipping/rotation).
3. Fit the disc.
4. Screw on the clamping nut corresponding to the
type of disc fitted 11.
