Switching On/Off - Hilti AG 180-20 Mode D'emploi

6.2 Guard
6.2.1 Fitting and removing the guard or guard with
cover plate 3
NOTE
The guard is already set to the correct tension by way
of the adjusting screw. If the tension is too low when
the guard is fitted, the adjusting screw can be tightened
slightly to increase the tension.
NOTE
The keyed locating lug on the guard ensures that only
a guard designed for use with the power tool can be
fitted. The keyed locating lug also prevents the guard
from coming into contact with the disc.
1. Release the clamping lever.
2. Fit the guard onto the spindle collar so that the
keyed locating lug engages in the recess provided.
3. Rotate the guard to the required position.
4. Secure the guard by closing the clamping lever.
5. To remove the guard from the power tool, follow the
instructions for fitting the guard but carry out the
steps in the reverse order.
7 Operation
CAUTION
In accordance with the applications for which it is de-
signed, the power tool produces a high torque. Always
use the side handle and hold the power tool with both
hands. The user must be prepared for sudden sticking
and stalling of the insert tool.
7.1 Cutting
When cutting, apply moderate feed pressure and do not
tilt the power tool or, respectively, the cutting disc (hold
at approx. 90° to the surface being cut). For best results,
start cutting at the smallest cross section when cutting
profiles and square tube.
7.2 Rough grinding
CAUTION
Never use abrasive cutting discs for grinding.
Best results are obtained when the disc maintains an
angle of 5° to 30° with the working surface when grinding.
Move the power tool to and fro while applying moderate
pressure. This will avoid overheating and discoloration of
the workpiece and ensure an even surface finish.

6.3 Fitting and removing the disc 5 6
NOTE
Diamond discs must be replaced when the cutting or
grinding performance drops significantly. This generally
is the case when the segments reach a height of less
than 2 mm. 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.
