Minimize Wear

All parts of the knitting machine have been carefully manufactured and tested by STOLL. Nevertheless, they are subject to wear.
You can keep the wear to a minimum if you check, clean, and lubricate the machine regularly and use it as intended.

NOTICE! Knitting programs with a high quantity of carriage strokes in relation to the running time increase the stress on many wearing parts. In this case, reduce the scheduled maintenance intervals!

The following table contains an overview of the wearing parts and the possible causes of excessive wear.

Wearing part	Possible causes of increased wear	Prevention
Fabric take-down rollers	Excessive fabric take-down values Contact pressure too high or too low Cleaning agents harmful to rubber Ether e.g. Fuels Yarns harmful to rubber Abrasive, sanding yarns Yarn finishes such as greases or oils UV radiation	Optimize the settings. Use cleaning petrol for cleaning.
Belts of the fabric take-down	Too high belt speed Fabric winding Thread windings Cleaning agents harmful to rubber Ether e.g. Fuels Yarns harmful to rubber Abrasive, sanding yarns Yarn finishes such as greases or oils UV radiation	Optimize the settings. Remove dirt and yarn residue immediately. Use cleaning petrol for cleaning. Cleaning Comb Take-down and Belt Take-down
Needle Brushes Brushes of the winding protection device * Brushes of the central lubrication *	Incorrect adjustment	Optimize the settings. Adjusting the brushes of the central lubrication Greasing Brush Control
Feed wheel rollers	Abrasive, sanding yarn Allowing the feed wheel to run unnecessarily Yarn tension too high	Optimize the settings. Friction feed wheel - Adjust the speed Use the feed wheels specifically.
Needle bed elements Cams	Excessive fabric take-down values Yarn too thick Insufficient lubrication Insufficient cleaning	Optimize the settings. Clean and lubricate according to needs. Set lubrication interval for needle bed
Yarn Guiding Parts Deflectors Yarn control units Eyelets	Abrasive, sanding yarn Yarn tension too high	Replace affected parts according to needs. Adjust the yarn tension according to needs.
Yarn Carriers	Insufficient lubrication Abrasive, sanding yarn Yarn tension too high	Clean and lubricate according to needs. Adjust the yarn tension according to needs. Check and adjust the yarn carrier clearance in the carriage directions.
Yarn Carriers	High quantity of carriage strokes in relation to the running time	Reduce the scheduled maintenance intervals.
Autarkic yarn carriers (ADF)	Stiff high-deep movement Soiling between moving parts of the yarn carrier Yarn finishes such as greases or oils Stiff or deformed guide rollers Yarn tension too high	Clean and lubricate according to needs. Check and replace guide rollers. Lubricating the Yarn Carrier Bow Oiling the Wires in the Yarn Carrier Rail Adjust the yarn tension according to needs.
Autarkic yarn carriers (ADF)	High quantity of carriage strokes in relation to the running time	Reduce the scheduled maintenance intervals.
Toothed belt of auxiliary take-down	Residual threads due to fabric windings were not removed carefully	Clean according to needs.
Toothed Belt Main drive Racking Comb Take-down Auxiliary Take-down Yarn Carriers (ADF) Toothed belt tension roller (ADF)	Belt tension too high: Danger of bearing damage Belt tension too low: Danger of position errors Tension roller of yarn carrier toothed belt worn-out Cleaning agents harmful to rubber Ether e.g. Fuels	Adjust the belt tension with a measuring device. STOLLService Check the clearance of the tension roller and replace the tension roller if necessary. Clean and lubricate according to needs. Oiling the Toothed Belt Oiling the Toothed Belts in the Yarn Carrier Rail Greasing racking device
	High quantity of carriage strokes in relation to the running time	Reduce the scheduled maintenance intervals.
Energy chain trailing cable	Heavy soiling Laying down of objects Damage to depositing gutter Not moved into position carefully after work at the rear of the machine Loss of oil due to worn central lubrication lines	Check and clean according to needs. Check the lines on friction. Especially in the turning area of the energy chain Replace the lines of central lubrication deeply worn-out by friction.
Battery	Loading time too short Frequent power failure Frequent switching off of the machine Lifetime or number of charging cycles exceeded	Check and replace the battery. Leave machine switched on for longer time (>6h).
Toothed Belt Carriage guide Engaging edge of yarn carrier plunger	Frequent staggering of the yarn carriers following the fabric selvedge Bearing clearance of the carriage guide Yarn carrier clearance in carriage directions	Use the automatic staggering of the yarn carriers following the fabric selvedge according to needs. Check and adjust yarn carriers to avoid tilting.
	High quantity of carriage strokes in relation to the running time	Reduce the scheduled maintenance intervals.
