Work piece guiding

The machine shall be equipped with a fence which complies with the following requirements:
a)

fence shall not be able to come into contact in any position with the cutterblock;

b)

it shall be attached to the machine and shall, on machines with a useful working width above 160 mm, be
laterally adjustable without the aid of a tool over the whole cutterblock length with the possible exception
of the range of 160 mm from the front table edge;

c)

if a tiltable fence is fitted, its normal position shall be at 90° to the face of the table and limited by an end
stop. Its movement shall be limited to 45° in a clockwise direction from its normal position when viewed

from the infeed end of the machine. No movement in an anticlockwise direction from normal position

when viewed from the infeed end of the machine shall be possible;
d)

gap between the outfeed table and the lower surface of the fence shall not exceed 5 mm where the fence
is in vertical position and 10 mm in any other position of the fence;

e)

it shall be capable of being locked in any position;

f)

minimum fence height and length, related to the useful working width, shall be as given in Table 3;

where an integral auxiliary fence is provided for shallow work, e.g. hinged to the main fence (see
Figure 5) its height shall not be less than 20 mm and not greater than 25 mm, its width shall exceed
55 mm and its length shall be equal at least to the length of the fence. If it is hinged to the main fence,
provision shall be made that it cannot fall from its rest position inadvertently into the working position e.g.
by fitting a locking device or by gravity. The auxiliary fence shall not be able to come into contact in any
position with the cutterblock.

If the machine is designed to be used with a demountable power feed unit it’s fixing shall not limit the fence
adjustment over the whole fence adjustment range.
Verification: By checking the relevant drawings, measurements, inspection of the machine and functional
testing of the machine.
