of a comparable material, have flat sides (within 0,1
mm per 100 mm) and shall have a thickness less
than the width of cut (kerf) and at least 0,2mm
greater than the saw blade plate. As

2, The distance of the riving knife from the gear rim
must be between 3mm and 8mm. measured
radially through the centre of the saw spindle. As

3. the highest point of the riving knife must be set
beneath the topmost teeth.
Check that saw blade clamping system is tight
before operating the machine.

Air current speed is 20m/s for vacuum suction dust
emission index, When air current speed of dust
collector
device
(in
accordance
with
EN
12779:2004) is not lower than 20m/s, ensure
machine can be normal exhausted. User must
wear dustproof mask.
1.

Ensure pressure drop of each dust collector outlet
carrying air current speed: 1100Pa
3.
Wind speed of dust collector tube m/s: dry
chips: 20m/s, water content is equal to18% wet
chips: 28m/s.
