MAINTENANCE (Continued)
LUBRICATION
Actuator and Linear Bearings
Do the following every six months (or more often if the linear
actuator seals are squeaking):
1. Thoroughly clean the carriage rails, drive shaft, and
shaft seals. Wipe the shafts and seals thoroughly with
a clean rag.
While cleaning, traverse the carriage several times to
clean the full length of the drive shaft and rails.
2. Flood-spray all three shafts with WD-40 or an equivalent
lubricant (do not use a Teflon-based lubricant) until
lubricant drips off the shafts. Then run the carriage back
and forth through its range of travel, to carry lubricant
onto the outer surface of the actuator bearings and the
inner surface of the seals.
NOTE: Because of the flood of lubricant, you may find
that the actuator slips and traversing is erratic or stalls.
This is not a problem, as it will be corrected in Step 3.
3. With a clean rag, wipe the excess lubricant from the
shafts. Run the carriage back and forth through its
range of travel, and wipe the shafts after each
traverse. Repeat u
ntil the shafts feel dry.
LUBRICATION FOR EXTENDED DOWN TIME/STORAGE:
If the machine will be shut down for more than one month, flood
the shafts and other appropriate parts with lubricant as outlined
above, and leave the lubricant in place until the unit will be used
again. Then repeat the above lubrication procedure before
operating. This procedure applies to the bearing rail and
bearing for the moveable right side electomagnet as well.
