INVOLVED AND APPLY ALL APPLICABLE LEGISLA-
TION.
1. Ensure that the structure to which the gear unit is to
be mounted is sufficiently robust and rigid to sup-
port its weight and operating stresses.
2. Check that the machine to which the gear unit is to
be installed is switched and cannot be accidentally
switched on again.
3. Make sure all mating surfaces are flat.
4. Make sure the shaft / shaft or shaft / bore are per-
fectly aligned for coupling.
5. Fit suitable guards to protect against the gear unit’s
external moving parts.
6. We recommend applying a protective paste to all
gear/motor mating surfaces and other parts such as
Klüberpaste 46 MR 401 or Tecnolube WRL 115 or
similar product, to ensure optimal coupling and pro-
tection against fretting corrosion.
7. Move the track drive in the mounting area applying
lifting methods.
8. Clean the mating surfaces from oils or paint and fit
the track drive on the machine frame (for the correct
orientation refer to the installation drawing).
9. Apply LOCTITE 270 on the thread screws (A). Fix the
gearmotor to the machine frame tightening the
screws (A) by a torque wrench at a torque shown on
the following table.

10. Clean the mating surfaces from oils or paint and
assemble the sprocket to the gearmotor.
11. Apply LOCTITE 270 on the thread screws (B). Fix the
sprocket to the gearmotor tightening the screws (B)
by a torque wrench at a torque shown on the follow-
ing table.
