1.3 WATER SYSTEM
ATTENTION
Danger of ice and frost damage!!
Frozen aggregates (e.g. do not switch on
water pump.
Do not heat with a flame or pour hot liquid
over
over.
Slowly thaw machine in a closed hall.
- Fill the water immediately before the first
application in the water box and water case.
ATTENTION
ATTENTION: No ice layer must form on the
inside walls of the water box and pumping
cylinder. Seals and pumping pistons will be
destroyed.
Possibly fill with warmed (not hot!) water.
The water in the water box does not freeze as
long as it is moving and all aggregates produce
sufficient heat.
It is possible to add antifreeze to the water in
the water case of the truck-mounted concrete
pump.
INFORMATION
Water offset with antifreeze may not come
into contact with concrete!
- Empty the entire water system (water pipes
and -pump, water box, reservoir) after
application. Switch on concrete pump briefly
to remove the water from the pumping
cylinder.
1.4 HYDRAULIC SYSTEM
SCHWING recommends appropriate hydraulic
fluids for different climates and applications.
See chapter 4.4
The multi-purpose hydraulic oil filled in at the
Herne plant can remain in the system, insofar
as the starting temperature does not drop
below -10° C.
Should work be carried out at temperatures
ranging between -10° C and
-15° C, changing over to winter oil (VG 32) is
required.
Otherwise, the great oil viscosity can cause a
risk of damage during a cold start. The
hydraulic pumps suck in air (oil foams) and will
be damaged.
When changing the oil, also replace the filters.
Make sure that the optimum operating viscosity
(16 to 36 mm²/s) is also at an oil temperature
between approx. 30 and 55° C for a hydraulic
oil of viscosity class VG 32.
INFORMATION
The system may only be fully loaded in the
area of the optimum operating viscosity.
The highest permissible temperature for a VG
32 is, however, below that of a VG 46 or VG 68.
