TROUBLE SHOOTING
Troubleshooting schedule
!
WARNING! If service operations or trouble

the stop switch in STOP position.
Problem Probable cause
The blade does not rotate. Roller knobs not tightened fully.
The blade not fitted on guide rollers correctly.
Rollers tensioned too much.
The blade rotates too slowly. Roller knobs not tightened fully.
Worn drive wheel.
The V-shaped inner diameter of the blade is worn.
The springs on the guide rollers are weakened.
Defective roller bearings.
The blade jumps out of its position. Roller setting too loose.
Worn guide rollers.
The blade not fitted on guide rollers correctly.
Damaged blade.
The blade warps. Rollers tensioned too much.
Blade overheating.
Segments break. Bent, twisted or badly maintained blade.
Continue to use the blade only if one segment is missing or leave for
reconstruction when the blade is worn max 50 %.
The blade cuts too slowly. Wrong blade for the material in question.
The blade slips.
The guide rollers does not move in and out freely. A seized roller can not press
the blade hard enough against the drive wheel.
Worn drive wheel. Abrasive material and too little water when cutting
increases the wear on the wheel.
Worn guide roller flange. When more than half of the width of the flange is worn
the blade slips.
The blade’s groove and inner edge are worn. Caused by inferior flushing of
abrasive material and/or a worn drive wheel causing the blade to slip.
