WARNING
•
Please use only pure gear oils for lubrication as the movements of the mechanical brake
and slip clutch may be affected resulting in performance degradation if lubricant oils other
than pure gear oils are used. Please replace old gear oil early as continued use of old gear
oil may hasten gear wear and result in noise.
•
When replacing the gaskets with new ones, the gear oils may spread initially but this will not
progress further as the gaskets are swelling-type gaskets.
The oiling criteria are shown in the table below. As these are applicable for standard use only, a suitable oiling
method needs to be established after checking the actual usage condition.
* When filling or changing oil, wipe old grease and iron dust before putting in new grease.
* Wipe as needed when oil separated from grease accumulates on the cover or other parts.
