Ryobi P2507 Manuel D'utilisation page 16

NOTICE:
Before each use, check to make sure that the
chain is properly tensioned. A cold chain is cor-
rectly tensioned when there is no slack on the
underside of the guide bar, the chain is snug,
and it can be turned by hand without binding.
During normal saw operation, the temperature
of the chain increases. The drive links of a cor-
rectly tensioned warm chain will hang approxi-
mately .050 in. out of the bar groove.
See the Adjusting the Chain Tension instruc-
tions in the Maintenance section of this manual
to properly adjust the chain tension.
