The jockey wheel with the beam is mounted by pushing the two
25mm holes horizontally over the two studs at the end of the
machine, then moving it slightly upwards and engaging the pin.
The two fixed wheels are mounted, one on each side of the
machine, by engaging the four 10mm pins vertically upwards
into the holes in the L-beams and then engaging the horizontal
pin to keep it from dropping out again. Install the R-clips into
the pins to keep them in place.
3.2.1.2 Refer to fig. 4 and slide the two base plates and “skate boards”,
one set at each end, in underneath the machine from the sides
and attach the links between the base plates and the lever arms.
Insert the R-clips to retain the links.
3.2.1.3 Lower the legs by turning the crank handles on top so that they
engage with the four bearings on the two skateboards. Under
operating conditions it may be necessary to fix the base plates to
the pavement to prevent them from moving around. The best
way is to drill 8mm holes about 50mm deep into the pavement
through the two holes in the base plate and to insert a 8mm steel
rod into each hole. Take care to fix the base plates in such a
way that the wheels of the skate boards will not jam on them,
i.e. they must stay 100% perpendicular to the centre line of the
machine.
3.2.1.4 Raise the machine high enough on its legs to remove the three
transport wheels. Adjust the two legs at one end of the machine
simultaneously by an equal amount and observe the bubble in
the spirit level mounted on top of the frame. This will avoid
twisting the frame by allowing it to stand on two diagonal legs
only.
3.2.2 Adjusting the height
The load of the wheels on the pavement is determined by the
spring settings and is practically independent of displacement.
