! WARNING
NEVER
extend the lever’s arm with a pipe or by any other method. The lever might
get damaged
! NOTICE
The ratchet crank and also the ratchet crank-lever is interchangeable with a standard
crank of correspondent type of jack. In case of replacement of the standard crank
with the RK 300 ratchet crank at jack with load capacity 5t it is necessary before
assembling to put on the square shank of the crank pinion the spacing tube – it is a
part of delivery of the RK 300 ratchet crank– for safeguarding the correct position of
the ratchet crank on the jack.
6.4 BEARING SURFACE CHECK-UP /floor, rough ground/
! NOTICE
ALWAYS
make sure that the bearing surface is sufficiently firm to hold tightly
supposed loading for all time of handling. The installation must not be
carried out on the surface where it is not possible to determine the load-
bearing capacity or that is instable.
ALWAYS
the operation personnel are responsible for the set-up!
6.5 TEST PRIOR TO USE
! NOTICE
(1) At first read again the previous articles of this manual and make sure that all steps
were correctly done and all parts are safety mounted.
(2) Visually check the jack and bearing surface whether they are without defects.
(3) Put to proof the jack function by the motion of the crank without loading.
(4) Carry out several jacking up and lowering with the suitable load (10% till 50% of the
load capacity). At the same time verify, whether the jack will hold firmly the load
without slipping when lowering and stopping.
7 OPERATION
7.1 APPLICATION OF THE JACK
7.1.1 The jack is multifunctional equipment destined for manual jacking up, lowering,
pushing and spreading of subjects in the workplace determined by the user. It
can be used not only in a current environment, but also in environments with
explosion risk in the event that there
is the symbol of the
protection type marked on
the label – see articles
2.3, 2.4 and 5.3 of this
OM. The lifters type
15-00
(load capacity 2,5 and 5t)
have an opening in the
foot which simplifies work
when
pushing
apart
objects
above
head
height. The lifter’s foot can
be easily attached in the
required position by using
a screw for example, without the need to use a helper. (fig. 6)
