● The amount of oil to be supplied to the nut-runner is about 1/100cc (1 shaft) per operation. The amountof oil to be supplied to the nut-runner is about 1/100 cc (1 shaft) per operation. The amount of oil tobe supplied to the nut-runner is about 10 to 12 drops (1 shaft) per minute of no-load operation. Thefarther the distance from the oiler to the nut-runner is, the more insufficient the lubricant will be.
● 3 Lubrication by the 3-point set type oiler is spray lubrication, and the state of lubrication varies
significantly depending on the distance from the oiler to the nut-runner.

Also, it is difficult to lubricate each shaft evenly. Therefore, when the equipment is used after a long
break or when it is first put into operation, lubricate directly from the nut-runner's hose connection (oilsupply port) with an oil spigot, etc and perform a no-load operation.
