The bridge guard must always be in position when planing bowed boards, as shown:
It is illegal to operate the surface planer without the bridge guard. The long accepted way of
placing the front portion of timber on the outfeed table and taking several cuts off the other
end then reversing the timber should not be used.
9.4 Edge Planing (Squaring)
When edging, the wood is passed between the end of the bridge guard and the fence. The bridge
guard should be adjusted both horizontally and vertically to leave only 10mm from both the feed
table and the workpiece, as shown below:

When edge planing, follow these guidelines regarding the correct positioning of hands:
Preparatory: Place the workpiece against the fence and move it with the right hand forward to
about the front edge of the infeed table lip. With the left hand bring the guard up to the
workpiece. The guard should be positioned as previously shown. This stage should not be carried
out while the cutterblock is in motion.
