CAUTION
Tampering with the carburetor settings may cause
damage to the motor.
The carburetor of this machine (jets H and L) has been
factory set for optimum performance and sealed to
prevent tampering. The idling speed of the machine
(jet T) may be adjusted by the user. All other adjust-
ments must be carried out at a Hilti service center.
NOTE
Use a suitable flat screwdriver (tip width 4 mm/ ೖ / ೤ೣ ")
and do not force the adjusting screw beyond its
intended adjustment range.
1. Clean the air filter.
2. Allow the machine to run until it reaches its
normal operating temperature.
3. Adjust the idling speed jet (T) so that the motor
runs smoothly when idling but the cutting disc
does not begin to rotate.
8.9 Cleaning
Careful cleaning of the machine is one of the main
prerequisites for trouble-free, reliable operation.
Heavy dirt and dust deposits on the motor and in the
cooling openings may lead to overheating.
Don’t permit foreign objects to enter the interior of
the machine.
Don’t use a high pressure jet system or running water
for cleaning.
Don’t use cleaning agents which contain silicone.
Clean the exterior of the machine at regular intervals
with a slightly damp cloth or a dry brush.
Check that all grips are clean, dry and free from oil
and grease.
8.10 Maintenance
Check all external parts of the machine and the
accessories for damage at regular intervals and check
that all controls operate faultlessly. Don’t operate the
machine if parts are damaged or when the controls
do not function faultlessly. If necessary, the machine
should be repaired by Hilti Service.
8.11 Checking the power tool after care and
maintenance
After carrying out care and maintenance, check that
all protective and safety devices are fitted and that
they function faultlessly.
8.12 Transporting the machine in a vehicle
CAUTION
To avoid a fire hazard, allow the machine to cool
down completely before transporting it.
CAUTION
The fuel tank must be completely empty before
the machine is shipped by a parcels service. We
recommend that the original packaging is kept for
use in the event of a need to transport the machine
in this way.
1. Remove the cutting disc.
2. Secure the machine to prevent it falling over,
causing damage or fuel spillage.
3. Transport the saw carriage only when the water
tank is empty.
8.13 Storing the machine for a long period of
time
DANGER
Store machines in a secure place when not in use.
When not in use, machines must be stored in a dry,
high place or locked away out of reach of children.

allow it to idle until all remaining fuel is used up.
