OPErATION MANUAL
Screw on the fixture (1), (2) into the spring cylinder (3) in or- •
der to release the shoes that grip the parking brake disc.
With the engine of the towed roller not
working, the steering will not work, the
operating brake is not fully operable
(unable to generate air pressure). Fixture
has been used to brake off the parking
brake and consequently the roller is not
being braked. Therefore when towing
the roller, downhill in particular, NEVEr
use the hauling cable, use the tow-bar!
When towing, use intact hauling cables
or tow-bar of loading capacity equal to
1,5 multiple of instantaneous weight of
the roller towed. NEVEr use a chain!
When towing, make sure persons present
stay within sufficient distance to avoid
their injury if the hauling cable breaks or
the hitch is damaged.
One must maintain the minimal angular
displacement of straight angle of haul-
ing. Maximal misalignment possible is at
an angle of up to 30°.
One must maintain the continuous mo-
tion when towing. Do NOT exceed the
towing speed of 2 km/hr. (1,2 mph).
Tow the roller for a distance as short as
possible – to recover it when bogged
down, or to remove it as an obstruction
during its defect. Do NOT tow for a dis-
tance over 300 m (0,19 mil) long.
The size of the towing machine should
correspond with the broken Machine.
Make sure it has sufficient pulling power,
weight and brake effect.
Unless the engine works, secure the
roller immediately after towing against
any motion, and then remove the fixture
away from the parking brake.
! CAUTION !
These are general requirements for safe hauling
of damaged Machine under normal conditions.
Consult with your dealer any and all different situ-
ation that may occur when towing.
Before braking off, use Scotch blocks for
wheels to secure the roller against any
spontaneous moving!
All the brakes are disabled!
No persons may dwell on the towed
roller with its engine not working.
