Once a year
Trained technicians are persons with the
necessary technical knowledge to inspect
the work equipment on account of their
professional training, experience and re-
cent occupational activities.
Please also note any other applicable na-
tional regulations.
Maintenance intervals
When used regularly to 100% of the rated
load: after raising and lowering by 100 m
When used regularly to 50% of the rated load:
after raising and lowering by 200 m
Perform the following tasks at these intervals:
Inspection work
Lubrication
Inspection work
Check that the crank moves freely
Check that the locking catch engages
After raising and lowering the winch by 100
m, check the wear of the brake discs and the
bonded brake pad.
The brake pad must be at least 1.5 mm
thick.
Oil and lubricating points
The winch is greased before delivery. Regrease
the following points regularly:
Drum hub
Ring gear
Bearing bushes of the drive shaft
Crank thread
Grease recommended by AL-KO:
OMV Whiteplex multipurpose grease.
Staburags NBU12K multipurpose grease.
CAUTION!
Danger from wear!
The winch operator must check the ca-
bles/straps for wear before every use
(DIN ISO 4309/BGR 500). Replace da-
maged cables/straps immediately.
The cable winch may only be inspected and
maintained by trained technicians.
The brake mechanism was treated by the ma-
nufacturer with a special grease (Wolfracoat
99113). Other oils or greases are not permis-
sible.

CAUTION!
Danger of brake release!
The load pressure brake can release due
to vibration. The cable winch should not
be used to secure loads! Do not remove
the crank while under load!
Danger of fatal injury! - Never stand under
suspended loads!
Risk of accidents! - The brake system can
overheat during extended lowering of loads.
No continuous operation!
Maximum lowering duration 2 - 5 minutes
depending on the load.
Only use ropes for which the hook is firmly at-
tached to the rope via a pressed rope loop.
End connections according to EN 13411-3
with thimbles according to 13411-1.
If not otherwise stated in the EN stan-
dards listed above, the cable end connec-
tions must be able to withstand a force
of at least 85% of the minimum breaking
force of the cable without a break.
Hook and connecting device (triangle) must
offer 4-times safety with cables and straps. No
permanent distortion is allowed under static
load with 2-times the nominal load. At 4-times
static load, bending open or deformation is
permitted, however the load must still be se-
curely held (see EN 13157). Alternatively, a
hook acc. to EN 1677-2 with guaranteed safe
working load must be used.
Sharp edges! Damage from scrapes, crus-
hing, cuts. Always wear work gloves.
Observe the required minimum breaking load
when using a strap.
The breaking force of the stitched strap
must be at least 7 times the specified ten-
sile force in the lowest cable position.
Do not knot together ropes / straps.
Do not expose straps to acids or bases.
Use a cover to protect straps from moisture
and constant solar radiation.
Do not exceed the tensile forces specified in
the technical data.
Always used non-twisting or low-twisting ro-
pes for lifting a freely suspended load that
could rotate during the lifting procedure!
