Remove the metal cap from the drum axle at the front of the machine. Then apply the grease as shown in the following pictures. After this, remove the housing cover and unscrew the screw on the drum axle. Start the machine so that the drum is running slowly and apply the grease into the opening using a grease gun.

Machine capacity 5 kg and above

Remove the screw on the metal cap at the front of the drum axle. Then start the machine so that the drum rotates slowly and apply the grease to the opening using a grease gun. At the rear, open the access to the drum axle and proceed in the same way as at the front.

Engine Chain

Start the machine so that the drum rotates slowly and the chain runs slowly. Then apply the lubricating grease to the inside of the chain until it is completely lubricated.

Cooling Tray lower chamber Cleaning

Carry out this maintenance once (1) a week or on demand.

Use a vacuum cleaner to remove the dirt.

Blower Cooling Cleaning

Carry out this maintenance every three (3) or six (6) months.

As standard, machines with a capacity of less than 1 kg do not have a cooling blower under the cooling tray. For these machines, clean the chamber under the cooling tray.

To clean the cooling blower, open the side door of the cooling tray. There you will see the opening to the cooling blower on the upper level. Clean it with a vacuum cleaner. Use a hose attachment if available.

Burner Installation Cleaning

Carry out this maintenance on demand. To reduce problems with burner performance, it is recommended that you clean the burner surface regularly. After you have cleaned the burner room, you can use a blower or blower gun to free the burner surface and openings from dirt.
