6.0 Guarding
All guards should be checked at the beginning of each working shift for damage etc.
6.1 The Front Cutterblock Guard
The yellow pillar mounted guard at the front of the machine is known as the bridge guard. The
bridge guard covers the cutterblock when surface planing. It is designed for use when surfacing,
and it is important that all operators are familiar with its use. Accidents can occur where the
guard is not properly adjusted or, in most cases, is not mounted on the machine. The guard is
provided with two hand locking arrangements, one for the vertical plane and one for the
horizontal. The former is positioned on the front frame of the machine, the latter on the
guard’s mounting block. The pillar mounting is grooved to receive the 8mm vertical adjustment
locking-lever, and the guard has been set in the factory so that when this is the case the guard
then sits centrally over the axis of the cutterblock.
This guard should be maintained through regular cleaning and lubrication, and if it becomes
distorted through misuse then it should be replaced.
6.2 The Rear Cutterblock Guard
To the rear of the fence a hinged guard is mounted which is known as the rear cutterblock
guard. This is designed to guard that part of the cutterblock that is on the side of the fence
remote from the bridge guard.
Do not remove the rear cutterblock guard from the fence.
6.3 The Rear Drive Guard
The rear drive guard should only be removed for maintenance and cleaning.
6.4 The Anti-Kickback Fingers
The anti-kickback fingers are an essential safety feature of the machine when thicknessing.
Their purpose is to drop and lock into the face of the workpiece in the event of kickback,
thereby preventing it being ejected from the machine.
The movement of the fingers may in time become restricted due to a build-up of waste, and
their freedom to move freely should be checked at least once every working shift and cleaned
as necessary to ensure that the fingers fall freely under their own weight.
