1. Disconnect the supply cord plug from the power
outlet.
2. Clean the clamping flange and the clamping nut.
3. Fit the 60 mm diameter reversible flange onto the
spindle the right way round, so that it is no longer
free to rotate.
4. Place the diamond cutting disc on the reversible
flange.
5. Fit the 60 mm diameter clamping flange and the
clamping nut.
6.
CAUTION Do not press the spindle lockbutton
before the drive spindle has stopped rotating.
Press the spindle lockbutton and hold it in this
position.
7. Use the wrench to tighten the clamping nut securely
and then release the spindle lockbutton.
8. Check to ensure that the spindle lockbutton has
disengaged.
6.3.2 Fitting synthetic resin-bonded fiber-reinforced
abrasive cutting discs (optional)
CAUTION
Never use flanges with a diameter of less than 80 mm
with synthetic resin-bonded fiber-reinforced cutting
discs.
The 80 mm diameter reversible flange is used for mount-
ing cutting discs with arbor size 22.2 mm or 25.4 mm.
Check which side of the flange fits the arbor hole in the
cutting disc. The flange must center the disc.
1. Disconnect the supply cord plug from the power
outlet.
2. Clean the clamping flange and the clamping nut.
3. Fit the 80 mm diameter reversible flange onto the
spindle the right way round, so that it is no longer
free to rotate.
4. Place the diamond cutting disc on the reversible
flange.
5. Fit the 80 mm diameter clamping flange and the
clamping nut.
6.
CAUTION Do not press the spindle lockbutton
before the drive spindle has stopped rotating.
Press the spindle lockbutton and hold it in this
position.
7. Use the wrench to tighten the clamping nut securely
and then release the spindle lockbutton.
8. Check to ensure that the spindle lockbutton has
disengaged.
6.4 Removing the cutting disc from the tool
To remove the cutting disc from the tool, follow the
instructions for fitting the disc but carry out the steps in
the reverse order.
6.5 Storing and transporting cutting discs
CAUTION
Remove the cutting disc from the power tool after
use.
The cutting disc may suffer damage if the power
tool is transported with the disc fitted.
CAUTION
Store the cutting disc in accordance with the manu-
facturer’s recommendations.
Incorrect or careless stor-
age may damage the cutting disc.
7 Operation
DANGER
Hold the power tool by insulated gripping surfaces
only, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
WARNING
Do not use the power tool if it starts with a jolt.
This
may be an indication that the electronic control unit is
defective. Have the power tool repaired by Hilti Service
immediately.
CAUTION
The power tool and the cutting operation generate noise.
Wear ear protectors.
Exposure to noise can cause hear-
ing loss.
CAUTION
The cutting operation may cause dangerous splinters.
Splintering material presents a risk of injury to the eyes
and body.
Wear eye protection and a hard hat.
CAUTION
The direction of advance is important. The power
tool must always be advanced with the guide wheels
ahead and in contact with the material being cut.
There is otherwise a risk of kick-back.
CAUTION
The electric supply voltage must comply with the in-
formation given on the type identification plate on the
power tool. 230 V power tools may also be connected
to a 220 V supply.
