the suction channel and suction lips.
- Wipe the machine with a clean, slightly
damp cloth.
- Monitor and maintain batteries in
accordance with the manufacturer's
specifications.
Weekly:
- For conventional wet-cell batteries,
measure the acid density of all battery
cells. Monitor distilled water.
After 400 hours of operation:
34 / 74
- After approx. 400 hours of operation, the
suction motor's carbon brushes must be
checked and, if necessary, replaced.
5.3 Battery charging
Connect battery charger to battery charge
connector (H2), at the same time
disconnecting the emergency stop
connector (G1/H1) and connecting the
charger to the fixed portion of the battery
charge connector (H2).
Warning! See Safety instructions, Sec.
5.1.
NOTE:
- Follow the battery charger manufacturer's
operating instructions.
- A minimum of 12 hours is required to fully
charge a battery.
- Battery and battery charger are matched
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).
This will expose the important serviceable
components. The battery charge connector
(H2) for the batteries is accessible from the
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.
