2.6.1 Cables
Only use cables that are marked and rated according to the specifications in “1.1 Electrical
specifications”. Don’t use excessive length of the cables. If a very long cable is needed we
recommend that you use a cable rated for more current and connect it to a distribution
central near the machine. Never lay the cable in a loop when operating the machine, this will
cause the cable to heat up and may cause fire. See “Figure 2-1” for explanation.
Figure 2-1 Recommended way to handle excessive cable length.
2.7 Definition of the “Safety off position”
The machine is in a safe condition where it cannot be any hazard.
How to set the machine in the Safety off position:
1. Switch off the machine
2. Wait for all drives to come to a complete stop
3. Disconnect the main power
4. Secure against unintended restart
Always disconnect the main power at the machine end to be able to prevent other persons
from accidentally reconnect the main power while working on the machine.
2.8 Safety regarding maintenance
Set the machine into the Safety off position before beginning any work on the machine.
See “2.7 Definition of the “Safety off position””.
Never work on the machine while power is still connected!
All parts must have come to a complete stop before beginning any work!
Adjustment, servicing and inspection work on the period of time limits, specified in this User
Guide as well as any information on the replacement or parts and equipment must be undertaken
and/or complied with!
These activities may only be undertaken by qualified personnel.

4 Maintenance
4.1 Precautions
Set the machine into the Safety off position before beginning any work on the machine.
See “2.7 Definition of the “Safety off position””.
Read “2.6 Electrical safety” before beginning any maintenance work.
Never work on the machine while power is still connected!
All parts must have come to a complete stop before beginning any work!
Adjustment, maintenance and inspection work must be undertaken by qualified personnel.
4.2 Battery Belts
Handling of battery belts.
To retain the capacity of the batteries it is very important that the following handling instructions
are observed.
After each use the batteries must always immediately be completely recharged.
This recharging is particularly necessary if the batteries will then be lying unused for around 3
weeks or longer.
Repeated storage without prior recharging will result in the batteries losing more and more charge
power, with the charge power eventually dropping to 20-30% of the batteries original capacity.
4.3 Directions for Battery charger TC PHASE 5
Connect the charger to the battery via the charging contact.
Connect the mains cable to the wall socket.
The red connection light comes on when charging commences.
The green light comes on when the battery is reday for use.
When the green and red lights are both on, the charger is contiuning with
adjustment/maintenance charging, and it should thus remain connected until the battery is
used.
Disconnect the mains cable from the wall socket.
Disconnect the charger from the battery.
The battery emits explosive gases during charging, so avoid flames and sparks.
The 24 Volt charger is only intended for lead batteries with 12 cells 14 Ah-60 Ah.
The charger must not be exposed to water.
The machine must not be connected to any power source while cleaning.
