Which oil should I fill up the petrol engine of my machine?
You can use a 10W40 or 15W40 engine oil unless otherwise specified. If you are unsure, just ask us.

What kind of petrol do I need to fill up the engine of my machine?
Unless otherwise specified, you should fill up with unleaded petrol (Euro 95). No E10. If you are in doubt, just ask us.

My engine runs for a short time and then dies off again. Is there a defect?
No, as a rule there is not enough engine oil filled in. The engines have a low oil cut-off, which is intended to protect the engine. If too little oil is filled in, it is very sensitive and triggers. Fill the oil into the engine until it reaches the thread of the filling opening.

Where can I get spare parts for a machine purchased from Jansen?

May I move my machine with chassis bought from you behind my car in road traffic?
No, the wood splitters, excavators, shredders etc. may only be moved on the road behind tractor units approved for agriculture or forestry at a maximum speed of 25 km/h. The prerequisite for this is the attachment of a light and number plate strip. Operation behind a passenger car is not permitted in road traffic. On your plot of land, you may of course pull these behind a car. However, make sure that the maximum speed of 25 km/h is not exceeded. 

How long does it take to ship my ordered machine?
We usually ship by a shipping company, which needs about 3-5 working days until delivery in germany. International shipments need about 8-12 working days. Please keep in mind that shipping companies do not operate on Saturdays.

Which hydraulic oil do I have to top up on my machine?
Almost all of our machines require a HLP46 hydraulic oil. If you are in doubt, just ask us.

Which transmission oil do I have to top up on my machine?
Almost all of our machines require an 80W90 or 85W90 gear oil. If you are in doubt, just ask us.

Is my machine delivered ready for operation?
The machine is delivered pre-assembled! If not otherwise stated, final assembly is to be carried out by you. If you have any questions, just ask us.
