front of the sweeper housing using counter sunk screws and lock nuts.

the container down on to the two adjustable hooks and fold the catch
lever down to lock in to place. (see diagram 1)
7.2 Container - Adjustment:
The height of the container may be altered by means of the black
handles on the height adjustment brackets. There is a graduated
indicative scale. The collector should be set evenly and level with the
front edge 4cm from the surface. The adjustment is affected by the
sweeping brush height and so should be monitored.
As the brush wears adjustments will need to be made.
Attention : Never allow the collector to rub the ground!!!

7.3 Assembly - side broom
When attaching the side brush to the sweeper housing for the first time
the drive pulley and support casing needs to be fitted to the right hand
of the sweeper housing as viewed from the operating position. Remove
the 17mm clamping bolt, discard the flat washer. Refit the clamping bolt
including the spring washer and drive pulley. Now mount the support
casing using four screws, lock washers and nuts. The screws should be
outside and the nuts inside. The side brush may now be slid on to the
support casing and secured with the M8 screw and spring washer. “A”.
Insert coach bolt “B” and assemble sweeper head assy. Using 17mm lock
nut and flat washer. Do not over tighten to allow free movement of
sweeper arm. Secure sweeper arm in the upright position with spring clip
“C”
Position the drive belt around the drive pulley within the mounting plate.
The top belt should lay with its back against the white roller at point “X”
and be at the top of the drive pulley.
The belt is tensioned in to the work position by removing spring clip “C”
and folding side brush arm down. Replace spring clip for safe storage.
Correct tension is achieved when a distance of 5mm is measured
between the tension grasp and tube (Point “Z”).
The spring pivot of the gulley brush arm assembly allows lateral
movement in case of obstacles.
