The jack safe working load on the rest is decreased by 30%.
6.1 JACK OPERATION INSTRUCTIONS
The jack is operated by the crank. Raising or lowering the load can be cut off in any lifting
height. A lowering brake and pawl system with forced mesh in the jack crank safeguard
the stability of the load position.
! NOTICE
At actuating force greater than 400N (it means when handling with the jack at the
safe load limit) the jack must be operated by 2 persons at least.
6.2 REST ADJUSTMENT
(only types 15-00-VK, 15-01-VK, 15-00-VK-RK, 15-01-
VK-RK).
Position of the adjustable rest can be changed in the
range given by a number of mounting positions on the
jack bar (only types 15-00-VK, 15-01-VK, 15-00-VK-RK,
15-01-VK-RK).
After removal of the breaking piece (2) and shifting of
the rest in the direction indicated by an arrow, fastening

get loose in the jack bar
and rest can be put
out. Carry out rest fitting-on to other position by
opposite procedure.
6.3 RATCHET CRANK OPERATION AND
THE RATCHET CRANK-LEVER
(only types 15-00-RK, 15-01-RK, 15-00-VK-RK, 15-01-VK-RK a HZ ).
6.3.1 Raising or lowering
Before
raising
hitch
up
the
changeover lever and set on the
mark of raising – up-arrow (see fig.3).
Carry out the raising by oscillating
(eventually rotation) motion of the
ratchet crank.
At the beginning of the raising before
the loading of the rack jack will take
place, hold the knurled nut so that it
would not be carried away by the
crank at its backwards motion.
Before lowering the load, shift the changeover lever to the position on the lowering mark –
down arrow (see fig.3). Lower down the load by oscillating (eventually rotation) motion of
the ratchet crank.
Make sure at each change of the position of the changeover lever, whether the lever gets
fitly to the socket in the ratchet crank.
First motion of the ratchet crank after reversing (after shifting of the changeover lever) is
slightly blocked. This state arises by an influence of stronger follow-through of the brake
