mains power supply before all
assembly work.
The drawings necessary for assembly can be found
in Annex A.7 (p. 28).

4.2 Sharpening the saw blade

Always disconnect the machine
from the mains power supply
before changing the saw blade!
Sharpening can be carried out on commercially
available automatic circular saw blade sharpening
machines. Refer to Table 1: EFA 85/185 (dia. 300)
and Table 2: EFA 86 / EFA 186 (dia. 230) for data
on the saw blade.
