Instruction Manual

► Depress the reset button (1) as far 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 15 seconds.
This cools the motor and helps prevent the
overload cutout from tripping again.
20.2 MSE 230 C
The MSE 230 C is equipped with an electronic
overload cutout to monitor motor temperature
and power consumption.

► If the indicator lamp (1) stays on for longer
than 2 seconds in an overload situation, the
power supply is interrupted and the saw is
switched off automatically – release the trigger
switch, then restart the saw.
► If the saw then restarts at a reduced RPM, it is
overheated and switches off automatically
after about 10 seconds – release the trigger
switch, allow the saw to cool down for about
one minute, then restart. If the saw again
restarts at a reduced RPM, it has not cooled
down sufficiently – allow it to cool down for a
long as necessary until it restarts at normal
RPM.
The indicator lamp glows only as long as the trig‐
ger switch is operated.
The indicator lamp flashes briefly to confirm it is
functioning every time the motor is switched on.
21 Operating Instructions
21.1 During operation
► Check level in chain oil tank.
► Top up with chain oil when the "min" mark is
reached, or earlier – see "Filling the Chain Oil
Tank".
21.1.1 Check chain tension frequently
A new chain has to be retensioned more often
than one that has been in use for some time.
21.1.2 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 neces‐
sary – see "Tensioning the Saw Chain".
21.1.3 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.
21.2 After finishing work
► Disconnect the plug from the wall outlet.
► Slacken off the chain if you have 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.
21.2.1 Storing for a long period

► Turn the guide bar over – every time you
sharpen the chain and every time you replace
the chain – this helps avoid one-sided wear,
especially at the nose and underside of the
bar.
