Part I of II
Verification: By checking the relevant drawings, inspection
of the machine and measurement.
Prevention of hazards during power operated
adjusting movement of the saw blade and/or fence(s)
on circular saw benches
Hazard of contact between the rip fence and the saw
blade
Only one axis powered movement shall be possible at a
time in the area where contact between the rip fence and
the saw blade is possible for any position of the saw blade
and fence(s). Beyond this area no movement limitations
apply.
The safety related parts of the control systems for
detection of the area where contact between the fence(s)
and the saw blade during movement of the saw blade
towards the fence and of the fence towards the saw blade
is possible shall be at least PL=c in accordance with the
requirements of EN ISO 13849-1:2008.
Unintended contact between the rip fence and the saw
blade, during movement of the saw blade toward the rip
fence and of the rip fence toward the saw blade shall be
avoided either by:
a) hold-to-run control for the movement of the fence,
whose safety related parts of the control system (see
also 5.2.1) shall conform to 5.2.7; or
b) on circular saw bench fitted with PLC/electronic pre-set
controls for the fence and the saw blade by stopping
any movement of the saw blade toward the rip fence or
the rip fence toward the saw blade when the minimum
distance between the saw blade and the rip fence is
equal or below 5 mm. The actual distance between the
