Lubrication and Operation

Auto bag closing machine KH-U800CG have to be cleaned and lubricated twice a day before the morning and afternoon start on the lubricating points indicated on the oilling diagram. The sight feed oiler has to be kept filled and should be adjusted so that it feeds two to three drops of oil per minute. The oiler has to be refilled latest, when 2/3 of the oil is used up.

For lubrication we recommend"10# auto bag closing machine white oil" or equivalent.

Before operating a new auto bag closing machine for the first time, the needle bar guard and the sight feed oiler, which come with the accessories of the auto bag closing machine, have to be screwed in. The sight feed oiler has to be adjusted. All lubricating points, indicated on the oiling diagram, have to be oiled.

For adjusting fill the sight feed oiler half-way with oil and turn the metering pin a little bit out and then turn it in, until there will flow approx, two drops of oil per minute. This can be checked on the sight glass. Secure the setting of the metering pin with lock nut. Fill the oiler.

Repeat the oilling of a new auto bag closing machine after 10 minutes of operation!

When the auto bag closing machine is out of operation, the oil flow can be stopped by tilting the lever on the lever on the sight feed oiler.

Imortant! The oil flow has to be switched on again before operating the auto bag closing machine.
