5.4.10 Oil Level Monitoring
A mark is cut into the bracket which supports the oil tank. This mark indicates the minimum level of oil required to run the
machine.
The minimum oil level must be maintained by the operator in accordance with section 7.2 (Oil level). The indication
range of the thermometer must cover the range from 0 to 300°C.
5.4.11 Rotation Speed Monitor
We recommend a rotation speed monitor on the compressor/vacuum pump with the indicator visible to the operator during use.
See
section 6.6 for details.
5.5 Cooling
The RFL 102 is air cooled, which means that during installation it must be ensured that the cooling air can circulate freely and that
the openings of the ventilating system must not be covered.
The machine should not be mounted against a closed surface. This would impair the flow of cooling air, thus causing the possible
failure of the machine due to overheating.
5.6 Drive
The rotation direction must correspond to the direction of the arrows located on the machine body.
We recommend a rotation speed monitor on the machine with a display which is visible to the operator.
In any case, the rotational speed must be monitored after assembly of the compressor/vacuum pump, and operating instructions
for the operator of the vehicle must be available.
With drive via combustion engine, a rotational speed control device which prevents excessive speed when load decreases, must
be installed on the engine.
A soft start mechanism should be incorporated into the drive system if necessary, to ensure a smooth increase in speed from
stationary.
Axial thrust from the drive must not be transferred to the rotor shaft.
Drive couplings should be fitted on the rotor shaft with the existing M12 thread.
Drive couplings must not be hammered onto the rotor shaft.
A coupling guard must be installed in every case.
5.6.1 Hydraulic Motor
Selection and assembly of the hydraulic motor is the responsibility of the company completing the installation.
We can supply the correct mounting trunk as well as a coupling.
The compressor side of the coupling has already been mounted by us. After fitting of the mounting flange, the motor side of the
coupling must not transfer axial thrust to the compressor/vacuum pump.
Permitted speed ranges:
Driven by drive shaft 1000…1500 min
-1
(RPM)
