8. Maintenance and Lubrication
Unless otherwise specified the actuators are shipped with their full requirement of
grease for normal operation. The actuators should not need a lubrication refill within their
standard life provided they have been installed and used correctly. Should the unit
require lubrication then use one of the following extreme pressure greases or their
equivalent:
Shell Alvania WR2
BP Energrease LC2
Castrol Spheerol L-EP2
Mobil Mobilux EP2
If ambient temperatures exceed 50°C (122°F) consult Power Jacks.
