ATTENTION: After the replacement of components, a subsequent inspection by a
competent person is obligatory!
Inspection of the load chain (acc. to DIN 685-5)
Load chains must be inspected for mechanical damage at annular intervals, however
after 50 operating hours, at the latest. Inspect the load chain for sufficient lubrication
and check for external defects, deformations, superficial cracks, wear and corrosion
marks.
Round-section steel chains must be replaced when the original nominal thickness ´d´
on the chain link with the worst wear has been reduced by more than 10% or when the
chain has elongated over one pitch ´pn´ by 5% or over 11 pitches (11 x pn) by 3%.
Nominal dimensions and wear limits are shown in table 2. If one of the limit values is
reached, the load chain must be replaced.

Maintenance of the load chain
In most cases, chain wear in the link points is caused by insufficient care of the chain.
In order to ensure optimal lubrication of the link contact points, lubricate the chain at
regular intervals adapted to the application with creep-type lubricant (e.g. gear oil). A
dry film lubricant, e.g. PTFE spray, should be used in environments where abrasives
like sand, etc., occur. The service life of the load chain can be increased by careful
lubrication to 20 - 30 times compared with a chain that is not serviced.
• When lubricating the chain, make sure the chain is in no-load condition so that the oil
can reach the contact points of the chain links which are subject to wear. Chain link
parts contacting each other must always be coated with lubricant, otherwise increased
wear on the chain results.
• It is not sufficient to lubricate the chains on the outside as this does not ensure that a
lubricant film can build up in the contact points.
• With a constant lifting path of the chain, the change-over area from lifting to lowering
movement must be checked in particular.
• Make sure that the load chain is lubricated over its entire length, also including the
part of the chain in the housing of the hoist.
• Clean dirty chains with petroleum or a similar cleaning agent, never heat the chain.
• When lubricating the chain, also check the chain for wear.
ATTENTION: It must be ensured that no lubricant can penetrate into the brake
enclosure. This may result in failure of the brake.
Replacing the load chain
The load chain must be replaced by a new chain of the same dimensions and quality in
the event of visible damage or deformations, however, when the discarding status has
been reached, at the latest. A load chain to be discarded must only be replaced by an
authorized specialist workshop. Only fit load chains which have been approved by the
manufacturer. Non-compliance with this specification will render the legal warranty or
guarantee void with immediate effect.
NOTE: Replacement of a load chain must be documented!
ATTENTION: Chains must only be replaced by chains of the same material, with
the same quality and the same dimensions.
Hoist with single fall
• Only pull in the new chain in no-load condition.
• 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.
• Remove load hook from the old load chain and suspend open load chain link in the
loose end of the load chain.
• Suspend the new, lubricated load chain also in the open link and pull it through the
hoist unit (LIFTING chain movement).
• 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 and the load hook can be fitted on the new load chain just
pulled in.
• Fix the end of the idle fall of the new load chain on the housing or frame (depending
on model) of the hoist.
Hoist with several falls
ATTENTION: Only pull in the new chain when the bottom block is unloaded,
otherwise the bottom block may drop when the load chain is detached. Danger of
injury!
• 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.
• Detach the loaded-fall end of the load chain from the housing of the hoist unit or the
bottom block (depending on model).
• Suspend prepared, open load chain link in the now free load chain end.
• 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.
Inspection of the load hook and top hook
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% 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.

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.
The inspections have to be initiated by the operating company.

RANSPORT TORAGE
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 temporarily 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 lubricant film should be applied to the chains.
• Since the brake disks may freeze at temperature 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.
