- Suspend the new, lubricated load chain
also in the open link and pull it through
the bottom block and the hoist unit (chain
movement UP).
- Do not fit a twisted chain. The welds must
face outwards from the chain wheel.
- When the old load chain has passed through
the hoist unit it can be detached together
with the open chain link.
- Fix the loaded-fall end of the new load chain
on the housing/frame or on the bottom block
(depending on model) of the hoist.
- Fix the loose end of the idle fall on the hoist
instead of the old load chain.
ATTEnTion:
The loose end of the idle
fall must always be fitted to the chain stop
(Fig. 11).
Inspection of the load hook and top
hook (if fitted)
Inspect the hook for deformation, damage,
surface cracks, wear and signs of corrosion,
as required, but at least once a year. Actual
operating conditions may also dictate shorter
inspection intervals.
Hooks that do not fulfil all requirements must
be replaced immediately. Welding on hooks,
e.g. to compensate for wear or damage is
not permissible. Top and/or load hooks must
be replaced when the mouth of the hook has
opened more than 10 % (Fig. 17) or when the
nominal dimensions have reduced by 5% as
a result of wear.
Nominal dimensions and wear limits are
shown in table 3. If a limit value is reached,
replace the components.
Inspection of the brake
Immediately contact the manufacturer, if
irregularities are found (e.g. defective friction
disks). All components of the brake must
be checked for wear, damage, discoloration
caused by overheating and for functioning.
Friction disks must always be kept free from
grease, oil, water or dirt. Check the bonding
of the friction disks.
replacing the hand chain
ATTEnTion:
Chains must only be replaced
by chains of the same material, with the same
quality and the same dimensions.
- An open load chain link is required as a
tool. It can be obtained by using an abrasive
wheel to cut a section from an existing link
with the same dimension. The length of the
cut section must at least correspond to the
thickness of the link.
- Open the old hand chain (preferably on the
connection link) and suspend the open link
into the loose end of the hand chain which
lies „in front of“ the hand chain wheel.
- Suspend the new hand chain also in the open
link and pull it through the chain guides and
over the hand chain wheel.
- Do not fit a twisted chain. The welds must
face outwards.
- Separate the old hand chain including the
open connection link from the new hand
chain and connect the two loose ends of
the new hand chain by means of a new hand
chain connection link.

repairs may only be carried out by
authorized specialist workshops that
use original Yale spare parts.
After repairs have been carried out and
after extended periods of non-use, the hoist
must be inspected again before it is put into
service again.
Supervision
Every 3 years, the unit must be assessed by
a competent person or an authorised service
partner. During this inspection, the unit is
completely disassembled and all components
are subjected to a detailed assessment.
If this inspection is not carried out by a
competent person or an authorised service
partner, the ATEX declaration of conformity is
rendered invalid.
The inspections have to be initiated by
the operating company.
TrANSPorT, STorAGE, DECoMMIS-
SIoNING AND DISPoSAL
observe the following for transporting
the unit:
• Do not drop or throw the unit, always deposit
it carefully.
• Hand chains and load chains must be
transported in a way to avoid knotting and
formation of loops.
• Use suitable transport means. These
depend on the local conditions.
observe the following for storing or tem-
porarily taking the unit out of service:
• Store the unit at a clean and dry place.
• Protect the unit incl. all accessories against
contamination, humidity and damage by
means of a suitable cover.
• Protect hooks against corrosion.
• A light oil film should be applied to the
chains.
• Since the brake disks may freeze at tempera-
ture below 0 °C, the unit should be stored
with closed brake. Turn the hand chain
wheel clockwise to this effect and hold the
load fall at the same time.
• In the case of models with integral trolley,
grease the load bar as well as both threaded
rods to protect them against corrosion.
• If the unit is to be used again after it has
been taken out of service, it must first be
inspected again by a competent person.
Disposal
After taking the unit out of service, recycle or
dispose of the parts of the unit in accordance
with the legal regulations.
