Depth Gauges - Stihl OILOMATIC Manual

Condition
Typical wear patterns on running
faces of cutters, tie straps and drive
links.
Excessive wear on guide bar and
chain sprocket.
Result
Chain runs roughly, sticks and does
not cut straight. Excessive feed
pressure is necessary.
Cause
Chain dull or unevenly sharpened
(filing angle, side plate angle, cutter
length, depth gauges) and/or guide
bar not properly maintained (burrs,
groove depth). Chain therefore
wobbles in bar groove or runs at an
angle.
Remedy
Install new chain sprocket, guide
bar and chain. If only one of these
parts is replaced, it will be quickly
worn again by the other defective
parts.
