NOTE! NOTE!
For connecting and disconnecting hydraulic hoses
for 3rd hydraulic function, see page
174 . Always
check the control functions for the attachment
before starting to work.
The clamshell bucket (also called Mulch grab
bucket) is most suitable for loading bulky material,
e.g. biological waste, tree branches, bulky refuse as
well as for manoeuvring the shredder machine.
- The clamshells are operated with control lever 2
(version 1A) or right roller control knob (version
1B) or lever 3 (version 1C). See page
66
and
forward.
- When entering into the material keep the
clamshells fully open, as otherwise the resulting
very high pressure may cause leaks on hoses
and seals.
- Do not operate the clamshells with full power
against the end stop. Due to the high opening/
closing speed the cylinders may be damaged.
NOTE! NOTE!
In order to manoeuvre the shredder machine with
the ball button tilt the clamshell bucket fully
backwards and close the clamshell.
Material which is trapped between cylinder and
bucket must be immediately removed, as
otherwise the piston rod of the cylinder may be
damaged or bent.
Check hydraulic lines at regular intervals for leaks
and visible external damage, replace if
necessary.
Grease the bearings on claws and cylinders every
50 operating hours
50 operating hours. For quality of grease, see
page
276
.
Always relieve the pressure in the hydraulic
system before starting maintenance or repair
work.
Work in hydraulic systems must only be
performed by authorized personnel.
