CAUTION: To prevent cuts, wear protective
gloves!
Remove the sprocket guard, bar, and chain.
Use the combination wrench to disengage the
chip deflector, and remove it.

a 3/8" saw chain, be sure to first cut out the
the marked portion of the chip deflector 1!

necessary to install a new chip deflector
(957.213.220).
