One of the troubleshooting indicator
LEDs on the control panel is lit up.

See section 7.5, “Adjust the chain lock”.
The air pressure is too low.
Check and adjust the air pressure.
The wrong cutter is sharpened.
The chain was in the incorrect
position when the machine was
started.
Find the cutter to be sharpened and make
sure that it is in the correct position before
the machine is operated. See section
6.2.5, “Make the grinding settings”.
The top-plate angles are not the same
(e.g. 35° in one direction and 25° in the
other) when the grinding head turns in
the 2 different directions.
The M6 nuts needs to be adjusted.
See section 6.2.3, “Set the top-plate
angle”.
Wrong parts of the cutters are
sharpened.
The pitch adjustment wing is not in
the correct position for the type of
chain used.
See section 6.2.5, “Make the grinding

A cutter was caught on the chain
pusher, because the chain pusher
is worn out and the material is
uneven.
• Loosen the screw that holds the chain
pusher in its position.
• Discard the chain pusher in accordance
with local, state, and national laws and
regulations.
• Attach a new chain pusher and fasten
the screw.
Rasp the chain pusher until the material
is even.

slowing down before it touches the
cutter.

The top-plate angle is too aggressive.
The top-plate angle setting is
incorrect.
See section 6.2.5, “Make the grinding

The metal of a cutter turns blue during
grinding, which is an indication of
damaged or weakened metal.
The grinding speed is set too high
and the metal is overheated.
Replace the damaged cutter or discard the
chain. Lower the speed on the grinding
speed knob, see section 4.6.2, “Grinding
speed knob”.
