8.7 Replacing the vent valve
To ensure correct functioning, renew the breather valve yearly.
When replacing, prevent dirt and damaging atmospheres from entering the gearbox.
If too much oil is contained in the gearbox, oil will escape from the breather valve. Correct
the oil quantity and replace the breather valve.
8.8 Checking the oil level sensor (optional)
The oil level sensor indicates the oil level only when the gearbox is shut down.
Lower the oil level and fill it up again until the oil level sensor gives a switching signal.
Please refer to the separate operating instructions for the oil level sensor.
8.9 Cleaning the gearbox
Explosion hazard due to overheating of the machine caused by a layer of dust
Deposits of dust have a thermally insulating effect, which can lead to the machine
overheating. The maximum surface temperature of the machine cannot be adhered to. Dust
can be ignited causing an explosion. This can result in death, serious injury or material
damage.
• Regularly remove dust from the machine.
• Do not allow dust layers thicker than 5 mm to build up.
Do not switch the machine on until the dust has been completely removed.
Dust deposits cause higher housing temperatures
Dust deposits prevent heat radiation.
Keep the geared motor free from dirt and dust.
