6.2.4 Severe Duty
This is defined as open/close service when run loads exceed 30% of the unit rating. This also includes all modulating
applications.
NOTE: Oil should be changed every 3000 seats for open close service, or sooner if the oil has been contaminated.
The spares suggested for severe duty are identical to the long-term duty spares.
6.3 Other Concerns
There are other unique application requirements that may result in additional parts being added to the list of recom-
mended spares. Some additional issues or requirements that should be considered when determining required spare
parts include (but are not limited to):
1. Maintenance Program
2. Frequency of operation
3. Modulating duty
4. Frequent operation by handwheel
5. Regular testing
6. Stall/overload condition
Limitorque strongly recommends using OEM parts to support and maintain your Limitorque actuator. Installing
parts other than genuine Limitorque parts could cause premature failure of your Limitorque actuator and voids any
remaining warranty.
The above guidelines are provided to assist you in determining your unique spare parts needs. Please contact your local
Limitorque Sales Office or local Au-tho-rized Stocking Distributor for additional help in evaluating your needs.
