24 Operations Manual Hurricane 700 XTT / Hurricane 850 XTT
The parking brake is engaged. Release the brake.
Check the components (drive motor, drive control
unit, connectors).
Have the faulty component replaced.
The washing head does
not go down
The fuse FU5 has blown.
Check and remove the causes that made the fuse
blow, then replace it.
The head descent actuator is disconnected or
broken.
Have the connection restored or the actuator
replaced.
The batteries do not
ensure normal work
time
The poles and charging clips of the batteries are
dirty and oxydized.
Clean and grease the poles and clips, recharge the
batteries.
The electrolyte level is low.
Add distilled water topping up all elements
according to the instructions.
The battery-charger does not work or is
unsuitable.
See instructions relative to the battery-charger.
There are considerable differences in density
between the various elements of the battery.
Replace the damaged battery.
The machine is working with a too high pressure
on the brush.
Reduce pressure on the brush.
The storage battery
gets flat too fast
during use, although
it has been charged in
the correct way and
when tested with a
densimeter at the end
of recharging, it turned
out to be uniformly
charged.
The storage battery is new and does not give
100% of its expected capacity.
It is necessary to “run-in” the storage battery by
20-30 charges and discharges to obtain maximum
performance.
The machine is used at its maximum capacity
for continuous periods and the autonomy is not
sufficient.
Use, if possible, storage batteries with larger
capacity or replace the storage batteries with
others already charged.
The electrolyte has evaporated and does not
cover the plates completely.
Add distilled water, topping up all elements until
the plates are covered and recharge the storage
battery.
The storage battery
gets flat too fast during
use, the recharging
with an electronic
battery-charger is too
fast and at the end the
storage battery gives
the right voltage (about
2,14V for each empty
element), but it turns
out to be not uniformly
charged when tested
with densimeter.
The storage battery, already filled with acid by
the manufacturer, has been stored for a too long
time before being recharged and used for the first
time.
If the recharging with a normal storage-charger is
not effective, it is necessary to carry out a double
recharging consisting in:
• A slow recharging of about 10 hours with a
current equal to 1/10 of the rated capacity
expressed in 5 hours (ex.: for a storage
battery of 100Ah(5), the current should be
10A, realized by a manual batterycharger);
• One-hour pause;
• Charging with a normal battery-charger.
