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 
pin (1) 

. 2 

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
