The motor will suffer damage if run with fuel mixed in
the wrong ratio or with unsuitable oil. Use the following
mix ratio with Hilti two-stroke oil: 1 part oil + 50 parts
gasoline. Use the following mix ratio with quality two-
stroke oil with the TC classification: 1 part oil + 25
parts gasoline.

fuel container.
2. Add the gasoline to the fuel container.
3. Close the cap on the fuel container.
4. Mix the fuel by shaking the fuel container.

6.2 Fitting and changing the cutting disc 3
CAUTION
Cutting discs which are damaged or out of round
(causing vibration) must not be used.
CAUTION
The maximum permissible speed of the disc or blade
must be at least as high as the maximum speed
printed on the machine.Accessories driven at a speed
above their maximum permissible speed may break and
fly apart.
CAUTION
Use only cutting discs with a 20 mm or 25.4 mm (1")
arbor hole.
CAUTION
The cutting discs, flanges or other accessories must
properly match the arbor size of the machine. Cut-
ting discs or accessories with arbor holes that do not
match the mounting hardware of the machine will run out
of balance, vibrate excessively and may cause loss of
control.
