-  If the hoist is to be used for frequent lowering 
from large heights or in indexed operation, 
first  consult  the  manufacturer  for  advice 
because of possible overheating.
-  The top hook and the load hook of the unit 
must  be  in  a  vertical  line  above  the  load 
centre of gravity (S) when the load is lifted, 
in order to avoid load sway during the lifting 
process (Fig. 1).
-  The selection and calculation of the appropri-
ate supporting structure are the responsibil-
ity of the operating company.
-  The operator must ensure that the hoist is 
suspended in a manner that makes it pos-
sible  to  operate  the  unit  without  exposing 
himself or other personnel to danger by the 
unit itself, the suspension or the load.
-  The operator may start moving the load only 
after it has been attached correctly and all 
persons are clear of the danger zone.
-  Do not allow personnel to stay or pass under 
a suspended load.
-  A  lifted  or  clamped  load  must  not  be  left 
unattended or remain lifted or clamped for 
a longer period of time.
-  The hoist may be used at ambient tempera-
tures between –10 °C and +50 °C.
  Consult  the  manufacturer  in  the  case  of 
extreme working conditions.
ATTENTION: Before use at ambient tem-
peratures of less than 0 °C, check the brake
for freezing by lifting and lowering a small
load 2 - 3 times.
-  Prior  to  operation  of  the  hoist  in  special 
atmospheres (high humidity, salty, caustic, 
alkaline) or handling hazardous goods (e.g. 
molten compounds, radioactive materials), 
consult the manufacturer for advice.
-  Always transport the load in the horizontal 
direction slowly, carefully and close to the 
ground.
-  When  the  unit  is  not  in  use,  position  the 
suspension (e.g. bottom block, load hook) 
above normal head height, if possible.
-  For  attaching  a  load,  only  approved  and 
certified lifting tackle must be used.
-  Correct operation involves compliance with 
the  operating  instructions  and  in  addition 
also  compliance  with  the  maintenance 
instructions.
-  In  case  of  functional  defects  or  abnormal 
operating noise, stop using the hoist imme-
diately.

(List not complete)
-  Do not exceed the rated load capacity (WLL) 
of the unit and/or the suspension and the 
supporting structure.
-  The unit must not be used for pulling free 
fixed loads. It is also prohibited to allow loads 
to drop when the chain is in a slack condition 
(danger of chain breakage).
-  Removing or covering labels (e.g. by adhe-
sive labels), warning information signs or the 
identity plate is prohibited.
-  When transporting loads ensure that the load 
does not swing (Fig. 2) or come into contact 
with other objects.
-  The load must not be moved into areas which 
are not visible to the operator. If necessary, 
he must ensure he is given help.
-  Driving the unit with a motor is not allowed.
-  The unit must never be operated with more 
than the power of a person.
-  Welding on hook and load chain is strictly 
forbidden.  The  load  chain  must  never  be 
used as a ground connection during welding 
(Fig. 3).
-  Side pull, i. e. side loading of either the hous-
ing or the bottom block (Fig. 4) is forbidden.
-  The load chain must not be used as a chain 
sling (Fig. 5).
-  A  unit  changed  without  consulting  the 
manufacturer must not be used.
-  Do not use the hoist for the transportation 
of people (Fig. 6).
-  Do not knot the load chain or connect it by 
using pins, bolts, screw drivers or similar. Do 
not repair load chains installed in the hoist 
(Fig. 7).
-  Removing the safety latches from top and/
or load hooks is forbidden (Fig. 8).
-  Never attach the load to the tip of the hook 
(Fig. 9).  The  lifting  tackle  must  always  be 
seated in the saddle of the hook.
-  Do  not  use  the  chain  stop  (Fig. 11)  as  an 
operational limit device.
-  Turning  of  loads  under  normal  operating 
conditions  is  not  allowed,  as  the  bottom 
blocks of the hoists are not designed for this 
purpose. If loads must be turned in normal 
operation, an anti-twist swivel must be used 
or the manufacturer must be consulted.
-  Only  one  load  lifting  attachment  may  be 
suspended in the load hook of the hoist.
-  Never reach into moving parts.
-  Do  not  allow  the  unit  to  fall  from  a  large 
height.  Always  place  it  properly  on  the 
ground.
-  The  unit  must  not  be  used  in  potentially 
explosive atmospheres.

Shorten or extend the hand chain
Adjust the length of the hand chain so that 
the distance of the lower end to the floor is 
between 500 – 1000 mm.
Note: For safety reasons, hand chain links
may only be used once.
-  Look  for  the  non-welded  link  of  the  hand 
chain, bend to open and discard it.
-  Shorten or extend the chain to the required 
length.
ATTENTION: Always remove or add an even
number of chain links.
-  Use a new link to close the loose chain ends 
by bending it (for extending the hand chain, 
two new chain links are required).
ATTENTION: Do not twist hand chains while
fitting.
inSPection Before initiaL
oPeration
Prior  to  initial  operation,  before  it  is  put 
into  operation  again  and  after  substantial 
changes, the product including the supporting 
structure must be inspected by a competent 
person*. The inspection mainly consists of a 
visual inspection and a function check. These 
inspections are intended to establish that the 
hoist is in a safe condition, has been set up 
appropriately and is ready for operation and 
that any defects or damage are detected and 
eliminated, as required.
*Competent persons may be, for example, the
maintenance engineers of the manufacturer or
the supplier. However, the company may also
assign performance of the inspection to its
own appropriately trained specialist personnel.
Before putting the unit into operation,
check functioning of the chain drive in
unloaded condition.
inSPectionS Before Starting
WorK
Before starting work, inspect the unit including 
the  suspension,  equipment  and  supporting 
structure for visual defects, e. g. deformations, 
damage, cracks, wear and corrosion marks. 
In addition also test the brake and check that 
the hoist and the load are correctly attached.
checking the brake function
Before starting work, always check operation 
of the brake:
To do this, lift, pull or tension and lower or 
release a load over a short distance with the 
unit.  When  the  hand  chain  is  released,  the 
load must be held in any position.
This  check  is  intended  to  ensure  that  even
