Replacements and repairs

Safety is important with regards to
all
repair work on the drum. The following items
must therefore be observed at all times, as well as the items under safety at the
beginning of the instruction manual.
When replacing cylinders, the cylinder must always be filled with oil before it is sub-
jected to any load. It is therefore recommended that the cylinder is mounted on the
fixed part of the frame first, after which the cylinder is filled with oil and then
mounted onto the opposing section.
All maintenance and repair work on the drum may only be carried out after the ma-
chine has been secured against accidental starting by lowering the machinery at
the base or maintaining it in transport position, the tractor is braked, the engine
stopped and the ignition key removed.
For all repair work on the hydraulics, always pay close attention to safety. Before
starting work, the pressure must be released from the hydraulic system and it is a
requirement that the section is supported from below.
After any repair work on the hydraulic system, all air must be removed from the sys-
tem before use in order to protect against breakdown and personal
injury.
