Installation

The machine must be placed on firm ground e.g. cemented floor. The ground must be level in order to 

avoid tensions in the machine when fixing it to the floor.
Check that the motor is branched to the right voltage. Also check the direction of rotation. Plates with 

“Forward” and “Reverse” are mounted on the protection cover of the foot switch. 
If the machine is equipped with motor powered setting of the bending roll and/or  the lower roll also 

check the voltage and oil level here.

Maintenance

The machine is delivered with greased bearings for about 200 hours’ continuous duty. After this period it 

should be lubricated with ball bearing grease of good quality, e.g. Esso Multi purpose grease H or equiv-

alent. All rolls and worm gears are mounted on needle and ball bearings and therefore recommended 

grease should be used. Guides for the roll bearing box as well as sleeves for the upper roll and cone 

bending device to be lubricated when required. Grease lubs, see grease chart.
The gearbox is lifetime lubricated and doesn’t need any regular inspection. Should there be any leakage, 

please check oil level and refill if necessary.

Daily check

•  Brake function of the motor
•  All emergency stop functions

Parallelism of the rolls

Check that all rolls are parallel. If adjustment is necessary proceed as follows:

Between upper and  lower rolls:
•  Crank up the lower roll to its highest position.
•  Loosen the two nuts blocking the wedge on the transmission side.
•  Adjust by means of the wedge until the distance between the upper and lower rolls are the same in 

both ends

•  Lock the wedge by means of the nuts.

Between upper and bending rolls:
•  Press the bending roll by means of the lever up to its highest position.
•  Loosen the screw of the cam disk.
•  Adjust  until the distance between the upper and bending rolls is the same at both ends.
•  Retighten the screw against the cam disk .
