Intended use
The Modul E-Drive landing gear is intended for installation on semi-
trailers. It is used for supporting semi-trailers which are not hitched
up.
The electric drive is only used for extending and retracting the
landing gear – not for moving loads. The load is only allowed
to be lifted and lowered using the air suspension of the vehicle
or by manual operation of the landing gear in the low gear. Up
or unhitching is normally undertaken using the air suspension to
adjust the hitching height of the tractor vehicle to the laden or
unladen trailer. The landing gear can be used on laden and unladen
trailers. Loading is only allowed on correctly and securely parked
trailers in compliance with the corresponding safety regulations.
Any other usage requires the written approval of JOST.
Usage not in accordance with the intended use can represent a
danger to persons and a danger of damage to the landing gear.
The Modul E-Drive is suitable for connection to a 24 V electrical
power supply with negative vehicle earth. The Modul E-Drive is not
intended for uninterrupted, continuous operation. Uninterrupted
operation is limited to 15 minutes. After that, it is necessary to wait
for at least 30 minutes.
The landing gear is not an independently functional piece of equip-
ment. It is designed for mounting on a trailer. Re-evaluation of the
entire system with regard to safety is necessary following instal-
lation. It must not be used until it has been established that the
trailer on which the landing gear has been mounted complies with
the national regulations for road traffic. The landing gear is only
allowed to be put into operation in conjunction with the documen-
tation of the tractor vehicle and trailer as well as of the landing
gear.
Furthermore, no liability and warranty claims will be accepted in
the event of failure to comply with the intended use. The landing
gear is only allowed to be operated under the application condi-
tions prescribed in this documentation.
