to one another. We accept no liability if
battery chargers other than those
recommended by Wetrok are used.
- Do not recharge after brief periods of use.
(Allow at a minimum a 20% discharge
before recharging.)
- Recharge batteries from time to time if
they are not used for extended periods (to
prevent a deep discharge).
- The battery contacts should be covered to
prevent metal objects (such as tools) from
making a connection between them and
causing a short circuit.
5.4 Access to the batteries
- Use the main key switch key to unlock the
tank housing (E1).
- Then lift up the tank housing (E1) (see
Fig. E).

outside.
NOTE:
Make sure that, before you lift up the tank
housing (E1), the tank has been emptied of
its contents (see Sec. 3.5).
If the machine is used over multiple
shifts, acquisition of a second battery
pack and battery-switching device is
recommended. The Wetrok customer
service department will be happy to
assist you further.
