3.4. Cleaning and maintenance
CAUTION! The continuous operating time of the device is approximately
8,000 cycles * (excluding wearable parts). In order to ensure safe and
trouble-free operation, inspection and maintenance of the entire device
should be carried out after exceeding the service life limit.
Periodic inspection refers to the inspection of the unit after
approximately 100 cycles* of operation.
* The work cycle means lifting and lowering of the load once.
a) Pull the mains plug and let the unit cool down completely before cleaning,
adjusting or replacing accessories and when the unit is not in use.
b) Replace damaged or worn parts on an ongoing basis and keep proper
maintenance records.
c)
Periodically check the operation of the limit switches.
Carry out a test run without load.
•
Move the load "up". Do not stop the machine drive below the level of the
•
limit switch lever (7). The limit switch should be activated - the operation
of the device should be stopped.
•
Move the load "down". Do not stop the machine drive above the safe limit
of the steel cable on the drum. The lower limit switch should be activated
- the operation of the device should be stopped.
d) Periodically inspect the technical condition of the power and control cables.
e) Periodically inspect the condition of the braking system. The brake should also
be inspected if the motor makes unusual noises during operation or if the unit
is not able to sustain the rated load.
f)
Always after 200 operating cycles perform maintenance on the carrying cable
and blocks (lubrication).
g) Always check the technical condition of the carrying cable after exceeding 30
cycles of operation. A damaged carrying cable should be replaced
immediately.
h) Always check the technical condition of the hook and the winch block after
1000 operating cycles.
i)
Each time the unit operates for over 1000 work cycles, check the unit's
fastening screws.
j)
Use only non-corrosive cleaning agents for cleaning the surfaces.
k) After each cleaning, all the parts should be dried well before the unit is used
again.
l)
Store the unit in a dry and cool place protected from moisture and direct
sunlight.
m) Do not spray the unit with a stream of water or immerse it in water.
n) Make sure that no water enters through the ventilation openings in the casing.
