Sorry this is back on thread
Found the ALKO manuals on their site. You don't need a grease machine infact they show a man with a grease gun
Al-Ko Kober
The following is from their manual:-
- Rear axle requires lubricating (re-greasing) every 20,000 Km,
or once a year, which ever comes sooner.
The grease nipples are situated at the front or at the bottom of the axle tube (see illustration).
Any of the following grease compounds can be used for greasing the bearings on the axle:
Co. Klüber: Grease GL 1501
Co.CONDA: Grease 3746 SP
or Shell: Retinax LX Grease

Note:
The rear axle must be greased
when the rear axle is not loaded!
Note:
If the vehicle is fitted with AL-KO
Air Suspension, the axle is
maintenance free.
Air suspension specific data is to be found in the Instructions for Use - AMC Air Suspension Handbook. Art. Nr. 1560613
