Checking And Replacing The Chain Sprocket - Stihl MS 200 T Manual De Instrucciones

Checking and Replacing
the Chain Sprocket
N
Remove the chain sprocket cover,
chain and guide bar.
N Disengage the chain brake: Pull the
hand guard toward the front handle.
Replace the chain sprocket
– after using two saw chains or
sooner
– if the wear marks (arrows) on the
sprocket are deeper than approx.
0.02 in (0.5 mm) since this would
reduce the life of the chain. You can
use a gauge (special accessory) to
check the depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.
