2.2.2. Relubrication via central lubrication port (option)
1: Central lubrication (standard)
2: Central lubrication (Option)

Loosen lubrication port screw.

Move the cylinder slowly to the lubricating position until the lubricating port
becomes visible.

The lubricating ports have a diameter of 2.5 mm. Therefore you need a beaked
nozzle insert for your lubricating gun.

Use a stable pipe (no hose).

Insert the nozzle into the hole in the cylinder profile and place it orthogonally onto
the lubricating port.

Use the defined amount of lubricant.

The amount of lubricant applied can be defined by the number of pump strokes.
Pump the stated amount of grease onto a balance, while counting the pump
strokes.

2.3.1. Check toothed belt
In general, the high performance toothed belts used in the ETH are maintenance free.
Visual inspection of the timing belt is however required. Please check the toothed belt for the
following aspects:

Wear at the teeth

Cracks in the tooth root surface

Fractures in the belt back
If you find signs of wear, the toothed belt must be exchanged.
2.3.2. Toothed belt exchange
Under good operating conditions, the toothed belt may run for 6000 hours of
operation. After this time, the belt must be exchanged.
Good operating conditions are:

no negative environmental influences

perfect alignment of the shafts

approved and correct geometry of the pulleys

correct mounting

permitted transmissible drive torques are respected.
