Lubricator Service Interval
The Automatic lubricator should be inspected approximately
every 6 months. At the end of the lubrication period the pis-
ton becomes clearly visible through the clear nylon discharge
indicator cap located at the bottom of the PERMA® canister
(Figure 1); this helps indicate that the lubricant has been fully
discharged at which time the lubricator should be replaced.
When operating the gear unit 8 hours/day or less a replace-
ment interval of 12 months or 1 year is possible. Ambient
temperature will influence the discharge rate and may ex-
tend or shorten the replacement interval.
Ambient Considerations
The grease discharge rate is affected by the ambient tem-
perature. PERMA® indicates that the lubricator contents will
dispense for a 12 month period when the average tempera-
ture is 20 °C (68 °F). Grease dispensing rates depend primarily
on average ambient conditions and not extreme highs and
lows. Lower ambient temperatures will lead to slower dis-
pensing rates and higher ambient temperatures will lead to
faster dispensing rates.
Average Ambient Temperature

10 °C (50 °F)

30 °C (86 °F)
40 °C (104 °F)
♦ Values are approximate.
Discharge can also be influenced by type of lubricant, vi-
bration, and by the mating connecting parts in the lubrica-
tion system.
Activating the Automatic Lubricator
1. Loosen and remove the M8x16 assembly socket head cap
screws (1251).
