CONNECTORS FOR FILLING UP AND
DRAINING WATER - - Fig. 60
1. Connector for filling up water.
2. Water drainage tube.
3. Air line attachment.
4. Water drainage tube.
Water can be used to ballast the rear tyres if there is
no danger of freezing.
CAUTION
Water pressure filled--up must never exceed 4 bar
2
(kg/cm ).
HOW TO FILL- -UP THE TYRES WITH
WATER:
-- raise the wheel off the ground and move the tyre
valve to its highest position;
-- slacken the valve inner and wait for the tyre to
deflate;
-- lower the wheel until the tyre is around 30% flat
to prevent the weight of the water damaging the
inner tube;
-- screw connector NEW HOLLAND No. 291885
onto the valve seat and fit the water tube to
connector (1) remembering to disconnect it when
the tyre starts to swell in order to let air out;
-- when water escapes from connector (1) the tyre
is 75% full.
If you wish to fill--up less water, or achieve a lower
weight, position the wheel so that the valve is
lower;
-- remove connector (1), tighten up the tyre valve
and inflate with air to the specified pressure.
SECTION 3 - - FIELD OPERATIONS
LIQUID BALLASTING
HOW TO DRAIN WATER FROM THE
TYRES:
-- raise the wheel off the ground and move the tyre
valve to its lowest position;
-- unscrew the valve seal and drain the water;
-- screw connector NEW HOLLAND No. 291886
onto the valve seat, tubes (2) and (4) will come
into contact with the inner tube;
-- fill--up pressurised air through attachment (3),
the remaining water will escape through tubes
(2) and (4);
-- remove the connector and replace it with the
valve seal, then inflate the tyre to the specified
pressure.
