Holding the Saw
There are two ways of holding the saw
when starting.
On the ground
N Place your saw on the ground.
Make sure you have a firm footing –
check that the chain is not touching
any object or the ground.
N Hold the saw firmly on the ground
with your left hand on the front
handle – your thumb should be
under the handle.
N Put your right foot into the rear
handle and press down.
Between knees or thighs
N Hold the rear handle tightly between
your legs, just above the knees.
N Hold the front handle firmly with
your left hand – your thumb should
be under the handle.
Cranking
N Pull the starter grip slowly with your
right hand until you feel it engage –
and then give it a brisk strong pull
and push down the front handle at
the same time. Do not pull out the
starter rope to full length – it might
otherwise break. Do not let the
starter grip snap back. Guide it
slowly back into the housing so that
the starter rope can rewind properly.
Machines without additional manual fuel
pump: If the engine is new or after a long
out-of-service period, it may be
necessary to pull the starter rope several
times to prime the fuel system.
