Attachment And Operation - Scheppach HTH250 Original Bedienungsanleitung

Fuels have only a limited shelf-life, they are subject to
ageing. Outdated fuels and fuel mixtures may result
in starting problems. Therefore, mix only that quan-
tity of fuel which you can use within a month. Only
store fuels in containers approved and identified for
this. Keep fuel containers in a dry and safe area.
Make sure that fuel containers are kept out of the
reach for children.
Caution! Prior to starting the machine learn how to
put it out of action in emergency cases.
