4.1.1 - Cleaning

- Release the brake by supplying it with power (section 4.2.2)
- Remove the protective varnish from the sheave grooves, if
the case.
Do not use abrasive equipment. Use only a cloth
soaked in alcohol. Care must be taken not to get
any alcohol or grease on the brake disc.
WARNING: Use the alcohol in a well-ventilated area.

4.1.2 - Mechanical installation

- the GeaRless machine must be installed on a chassis
that is not subject to vibration and must be secured using 4
m12 screws class 8.8 and washers, tightened to a torque of
83 nm ± 10%. the screws must only be tightened, when the
cables and the traction sheave are perfectly aligned.
- check that the cables are of the correct type for the sheave
of the motor.
In case there are fewer ropes than grooves on the
sheave, install the ropes closest to the motor side.
4.1.3 – Rope Protection System
When the cables have been installed, fit or refit the bolts or
the complete protection system onto the motor.
Use loctite 242 (or equivalent) on the tap of each bolt and
tighten at torque 15 nm ± 10%.
There is a high risk of jamming your fingers
between the cables and the sheave.
In case of lateral rope pull, the motor must be
supported on the side of the feet, to avoid any
shearing force on the fixing bolts.

It is the responsibility of the user to connect the
motor in accordance with the current legislation
and regulations in the country of use. This is particularly
important as regards the size of the cables, the type and
size of fuses, the earth or ground connection, powering
