Overload Cutout; Operating Instructions - Stihl MSE 250 C Instruction Manual

Overload Cutout

The overload cutout interrupts the power
supply to the saw in the case of
mechanical overload due to, e.g.
excessive feed force
–
"lugging down" the motor
–
pinching the saw chain in the cut
–
If the overload cutout has interrupted the
power supply:
Pull the guide bar out of the cut.
N
If necessary, disengage the chain
N
brake – see "Chain Brake".
Wait for the overload cutout to cool
N
down.
1
Depress the reset button (1) as far
N
as stop – if the motor does not run
when you switch on, the overload
cutout has not yet cooled down
sufficiently – wait a while and then
depress the reset button again as
far as stop.
When the motor restarts:
Run the motor off-load for about
N
15 seconds. This cools the motor
and helps prevent the overload
cutout from tripping again.

Operating Instructions

During operation
Check level in chain oil tank.
N
Top up with chain oil when the "min"
N
mark is reached, or earlier – see
"Filling the Chain Oil Tank".
Check chain tension frequently
A new chain has to be retensioned more
often than one that has been in use for
some time.
Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
and can still be pulled along the bar by
hand. Retension if necessary – see
"Tensioning the Saw Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links must not come out of the
bar groove – the chain may otherwise
jump off the bar. Retension the chain –
see "Tensioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it
is not slackened off, it can damage the
drive shaft and bearings.
After finishing work
Disconnect the plug from the wall
N
outlet.
Slacken off the chain if you have
N
retensioned it at operating
temperature during cutting work.
NOTICE
Always slacken off the chain after
finishing work. The chain contracts as it
cools down. If it is not slackened off, it
can damage the drive shaft and
bearings.
