7.1 Adjusting the grip
7
WARNING
Do not attempt tp adjust the position of the grip while
the tool is running. Check to ensure that the grip is
engaged in one of the three possible positions.
To allow the power tool to be used comfortably in all
positions, the grip can be pivoted through 90° to the left
and the right.
1. Disconnect the supply cord plug from the power
outlet.
2. Release the locking lever by pulling it back.
3. Pivot the grip to the left or right as far as it will go.
4. Secure the grip in position by closing the locking
lever.
NOTE
The power tool cannot be switched on as
long as the grip is not locked in one of the three
possible positions.
7.2 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.
7.3 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.
7.4 Switching on / off
7.4.1 Switching on
1. Plug the supply cord into the power outlet.
2. Slide the on / off switch forward and then press it as
far as it will go.
In this way, the hand is closed around the power
tool, which ensures optimum safety while working.
7.4.2 Switching off
Release the on / off switch.
7.5 Restart interlock
NOTE
If the power tool is unplugged from the electric supply
while the on / off switch is pressed and subsequently
plugged back into the electric supply, the power tool will
not restart.
8 Care and maintenance
CAUTION
Disconnect the mains plug from the power outlet.
8.1 Care of the power tool
DANGER
Under extreme conditions, when used for working on
metal, conductive dust may accumulate inside the tool.
This may have an adverse effect on the tool’s protective
insulation.
Under such conditions, the tool should be
plugged into a ground fault circuit interrupter (RCD)
and use of a stationary dust removal system and
frequent cleaning of the tool’s cooling air slots is
recommended.
The outer casing of the power tool is made from impact-
resistant plastic. Sections of the grip are made from a
synthetic rubber material.
Never operate the power tool when the air vents are
blocked. Regularly clean the power tool’s air vents care-
fully with a dry brush. Do not permit foreign objects to
enter the interior of the tool. The motor’s fan will draw
dust into the casing and an excessive accumulation of
conductive dust (e.g. metal, carbon fiber) may cause
electrical hazards. Clean the outside of the power tool at
regular intervals with a slightly damp cloth. Do not use
a spray, steam pressure cleaning equipment or running
water for cleaning. This may negatively affect the elec-
trical safety of the tool. Always keep the grip surfaces
of the tool free from oil and grease. Do not use cleaning
agents which contain silicone.
NOTE
Frequent work on conductive materials (e.g. metal, car-
bon fiber) may make shorter maintenance intervals ne-
cessary. Take your individual work place risk assessment
into account.
8.2 Maintenance
WARNING
Do not operate the power tool if parts are damaged,
if the electronic control unit is defective or when the
controls do not function faultlessly. Have the power
tool repaired by Hilti Service.
WARNING
Repairs to the electrical section of the power tool may
be carried out only by trained electrical specialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly.
8.3 Checking the power tool after care and
maintenance
After carrying out care and maintenance work on the
power tool, check that all protective and safety devices
are fitted and that they function faultlessly.
