7.1 - Chain adjusment
1� Make sure that the adjusting bolts at the idler end are tightened
equally�
2� Start the motor and verify that the chain fits well in the sprocket
teeth�
3� If an adjustment is necessary TURN OFF THE MOTOR AND
LOCK OUT POWER SOURCE , then do the required adjust-
ments� Verify the adjusting bolts on the idler end�
4� Tighten all bolts�
When tightening the chain allow it to run at least a full chain re-
volution to determine if additional adjustments are required� Check
tension while machine is loaded� Check frequently during the first
10 hours of operation� Check periodically afterwards�
It takes many hours of running, under full load, for the chain and
gear box to reach their highest efficiency� They may, if necessary, be
put to work under full load immediately� However, to maximize the
lifetime of the machine, it is recommended to run it under gradually
increasing loads and to reach a full load only after about 20 hours�
7.2 - Lubricant and oil change
1� Check oil in gearbox regularly�
2� Grease all bearings monthly�
3� After 100 hours of running, a new worm gear unit should be
drained, flushed and refilled with proper oil�
4� Oil should be changed at least every 2500 operating hours or
every 6 months, whichever occurs first� Never mix 2 diffe-
rent types of oil. Be sure to drain and wash before
using another type of oil �
7.3 - Lubricant selection
Lubricating oil must have a viscosity sufficient to reduce friction and
allow the speed reducer to operate smoothly under high load and
impact� Consult table below for the choice of lubricant�
Where a wide temperature range is expected, the synthetic oil
EXXON SHC 629 is recommended�
Please keep in touch with our engineering department, especially
when operating reducers under special conditions such as high or
low speed, high temperature or heavy loads�
