The filters should be checked
periodically.
Oil Warning Hole
The oil warning hole on the cover of the
pump (1) is provided to warn the opera-
tor in case of a problem with the oil seals
in the cover.
It should be periodically chec-
ked whether oil comes out
from the oil warning hole.
When oil coming out of the oil
warning hole is spotted, the
product should be taken to
the nearest service centre.

4.9.2.2. Operating Instructions
Before Starting the Pump
•
It should be checked whether the
flow rate and the pressure of the
pump is suitable for the pressure
and oil demand of the system.
•
It should be checked whether the
pump connection was made in ac-
cordance with ISO or UNI
connection.
•
The tank should be filled to the max-
imum with fresh oil at proper viscos-
ity. It should be checked that the oil
filter is not connected to the pump
suction line. The oil filter should be
mounted on the tank return or pres-
sure line. If the oil filter is connected
to the pump suction line, the pump
cannot get sufficient oil from the
tank. This leads to overheating and
cavitation in the pump which results
in a drop in the efficiency and serv-
ice life of the pump.
•
Prior to the initial start, it should be
checked that the system is filled with
oil up to the pump inlet and all
valves are open. The pump should
never be operated without oil, even
for a second.
Operating the Pump
•
The initial operation should be car-
ried out without pressure at low
speed (idle speed for trucks) with
the tipper empty for a few minutes
and the operation, noise and any oil
leakage of the pump should be
checked. When something extraor-
dinary is noticed, the system should
be stopped and the problem should
be located.
•
Since the system will be filled with
oil after the initial start, the tank level
should be checked again and
topped up.
•
The pump should not be operated
above the pressure and speed val-
ues mentioned.
•
The pressure setting of the direction
control valve should not be
changed.
•
The periodical maintenance of the
system should carried out in due
time.
•
You should contact our service
centres for any problems.
If the instructions before and
during the operation of the
pump are not followed, the
product warranty will be void.
