MAINTENANCE
Danger due to electrical voltage! Handling the machine connected to the power
supply can lead to serious injury or even death. Always disconnect the device from
the mains before repair or maintenance work and secure it against unintentional re-
connection!
The machine is low-maintenance and contains only a few parts that the operator has to
maintain. Immediately rectify any malfunctions or defects that could impair the safety of
the machine. Repair work may only be carried out by qualified personnel!
14.1 Sharpening the saw blade
The saw blade can be sharpened several times without being removed from the machine.
Use a fine-cut square-blade file of 8–12'' for sharpening.
Pay attention to the following points when sharpening:
During manual sharpening only file the front rake of the tooth over a distance of
about 5–7 mm.
Always keep the original shape of the tooth.
Do not make sharp notches at the root of the tooth with the file. Always clean the
blade-clamps carefully.
