Operation

2.12 Lifting operations
Under the term “lifting operations” is understood the lifting, transporting and lowering of secured loads,
whereby assistance is required for fastening and loosening the load. Included is also the extraction
and lowering of pipes, shaft collars etc. It must be ensured that no one stands underneath the load
or operating attachment. The operator is not to swing the load over nearby persons. Loads must be
fastened that they cannot slip or fall off. Assistants must always stay within the operator’s vision. The
operator should move loads as near the ground as possible and avoid swinging the load. When using
the excavator for lifting and pipe­laying operations, the pipe laying operator should approach the boom
only from the side and only with the operator’s permission to be given only when the machine and boom
are no longer in motion.
2.13 Servicing, maintenance
Before all servicing and maintenance operations, and when refuelling, engine is to be switched off.
When working on the electrical system or when conducting welding operations, the battery should be
disconnected in order not to damage the alternator and to avoid accidental start of operation. On MENZI
MUCK with electric motor, all electrical devices and all connections should be switched off and protected
against accidental and non­authorised operation. Exceptions to these rules are those servicing and
maintenance operations which require a running motor.
2.14 Protective guards
Protective guards on moving parts may only be opened or removed when the motor is switched off and
protected against accidental and non­authorised operation. After completing assembly, servicing or
maintenance work, replace all protective guards.
2.15 Valves, hydraulic hoses
The rated pressures on the MENZI MUCK safety and control valves may not be adjusted without the
manufacturer’s permission. As soon as damage or leakage of the hydraulic hoses has been diagnosed,
they are to be replaced. Only hydraulic hoses recommended by the manufacturer are to be used.
2.16 Starting operation
Before operating the machine, check the oil levels, diesel engine and cooling water, hydraulic
oil, swing transmission. For the mobile version check wheel hub transmission. Check also
cooling water of diesel engine.
Before starting the Menzi Muck ensure persons are clear.
1. Insert ignition key and turn to Position 1. Now display unit must be initialised.
2. See chapter 6.3 for preheating
3. Turn ignition key to Position 3 and start engine. Release ignition key as soon as engine starts up.
Attempt starting continuously for a maximum of 10 seconds. Wait for approximately 1­2 minutes
between each starting attempt to enable the battery to recover.
4. The warning indicators may not appear when the engine is running. Refer to the operating manual
of the engine manufacturer in case of faults and when starting in winter.
