ATTENTION!
When you have finished turning the crank handle,

the crank recoiling. Watch out for the end of the lifting
motion.
Check the landing gear for damage and have any damage
repaired before use.
Park the trailer on firm, flat and level ground (see “Trailer

the landing gear if necessary.
Engage high or low gear and wind down the landing gear.
Shift from high gear to low gear before the foot makes con-
tact with the ground.
Uncouple the towing vehicle (see “Towing vehicle” and “Tow-
ing device” owner’s manuals).
Finally, hang the crank in the crank holder.
ATTENTION!
Do not move the uncoupled trailer, even with the “R-
foot”.
