It is recommended that the actuator be visually inspected after initial startup and twice a year thereafter,
specifically checking for uneven wear or discoloration of the thrust rod which may indicate side loading and lead to
premature seal failure. Contact the nearest Tolomatic service center with any concerns or questions.
Figure 7.1: A standard grease zerk allows periodic relubrication for Tolomatic IMA Actuators. This can be done
without removing the actuator from its installation.
7.3 Procedure for lubrication
Before starting any maintenance activities, confirm Tolomatic IMA Actuator is in full retract position and supply
power is shut off.
1.
Ensure Tolomatic IMA Actuator is in full retract position
2.
Using a standard grease gun, apply the grease (amount determined in previous section) into the grease
Zerk on the rod end of the actuator:
3.
Re-apply power to the Tolomatic IMA Actuator
4.
Complete five full extend / full retract moves of the Tolomatic IMA Actuator at low speed / low force to
properly distribute the grease
Do not over-fill with grease
Overfilling will cause a reduction in performance, excessive heat build up and potential premature failure.
7.4 Tolomatic IMA Maintenance and Repair
The only user serviceable component of the IMA actuator is the rod wiper.
Further disassembly of the IMA is not recommended. IMA actuators should be returned to Tolomatic for evaluation
and repair.
Contact Tolomatic for instructions on how to return the IMA actuator for evaluation.
