METHOD FOR LUBRICATING DRIVE SHAFT
NOTICE
Neglecting the greasing to the drive shaft may lead to breakage of the shaft, and the runout of the shaft
leads to a serious damage to the machine.
Observe the specified lubrication interval.
Use the special grease for drive shaft, and perform greasing every 4000 hours or every 2 years, whichever
comes sooner.
If the special grease is not used but common lithium base grease is used, perform greasing every 1000 hours
after then.
