8.2 Periodical inspections and servicing
The servicing intervals for the hoist are defined as SWP% periods. The actual operation of the hoist is
taken into account in SWP%. If the hoist is provided with a condition monitoring unit, the SWP value can
be read from the SWP-data counter display of the unit. Refer to the more detailed instructions given in
the separate operating instructions for the condition monitoring unit. The SWP% corresponding to the
SWP value can be found from the table below. Check the rating plate fixed to the hoist for classification
of the hoist's operating group.

The table below shows the service intervals for the hoist in SWP% periods and in calendar months. Items
for inspection and servicing refer to the servicing procedures described earlier in these operating
instructions. The servicing procedure must be carried out latest at the end of a SWP% period, or by the
end of the stated number of calendar months. Hoists without a condition-monitoring device must follow a
servicing procedure guide by calendar months. For ensuring the usability of the hoist the servicing
intervals can be shortened.
#
Hoists used under harsh conditions may require a shorter servicing interval than stated in the table
below. Consult with a representative of the manufacturer for a tailored service agreement.
#
If ambient temperature is frequently over 40 ºC (104 F) the servicing interval is half of the interval
stated in the table below.
!
Periodical inspecting and servicing procedure may only be carried out by a serviceman
authorized by the hoist manufacturer or service personnel adequately trained by the hoist
manufacturer.
