The cutting of thin-walled workpieces
(profiles, tubes etc.) requires slow
feeding to avoid excessive wear of
sawblade.
The feed speed is automatically
reduced at the end of the cut, when
the saw arm reaches the table, to
produce a finer cut.
The arm position where the reduction
starts can be adjusted on the cap
screw (A, Fig 17).

Gear Box Oil:
The gearbox oil must be changed after
the first 2 months of operation (after

Then change the oil in the gearbox
annually (respectively every 500
