The screw at the upper end of the level bolt tube under the control panel is responsible for
the adjustment in the front area. There are two screws on the rear suspension for adjusting
the height in the rear area.
f Loosen the lock nuts on the screws. The same effect applies to all screws: turning
clockwise lifts the machine, turning counterclockwise lowers the machine.
f The distance to the floor should be even at all points of the magnetic frame (see pictu-
re of side panels with sealings, Nos. 205, 85 and 87). A distance between 5 mm and 10
mm will suit most floors.
f Rubber sealings and brushes are attached to the front and side strips of the magne-
tic frame (No. 91). The strips serve to additionally seal the blast opening. If the machine
height setting is changed, the rubber sealings and brushes must be adapted accordin-
gly.
f Loosen the screws of the brush sealings (No. 89 and 93) that clamp the rubber strips
and move them in the required position. The rubber strips and brushes should always lie
flat on the floor.
Wear & tear on the blast wheel and shot cage
The blast wheel is a pure wear & tear part and must be checked regularly. We recommend
carrying out the first check after approximately 30 operating hours. The service life of the
wheel depends on how the machine is used.
For example a lot of wear & tear occurs when blasting soft concrete with a lot of surface
slurry. Concrete dust is a very aggressive substance and increases wear & tear enormous-
ly. This decreases when blasting steel or ceramic tiles. To give an accurate figure for the
lifetime of the wheel is therefore impossible. As a rough guide, this could be anywhere bet-
ween 30 and 60 hours.
Blast wheel with 6 blades (left) Shot cage (right)
f Remove the shot hose between the shot valve and the shot enter pipe. (Nr. 129)
f Loosen the four nuts which secure the blast wheel cover (No. 125) to the machine. Ca-
refully remove the blast wheel cover.
f There is a rubber seal between the blast wheel cover and the blast chamber, which can
stick on both sides during operation. If the blast wheel cover is removed carelessly, the
seal can be damaged.
f You can now see the centrifugal wheel in front of you. There is a hexagon socket screw
in the center of the wheel.
f Loosen the screw and remove the wheel from the blast chamber. Check the wear & tear
on the wheel. The thickness of the six blades should not be less than 5 mm. If less, the
blade could break and destroy the whole wheel. Also check the distribution fingers on
the inside of the wheel for wear & tear.
f The shot cage (No. 127) is like the blast wheel – a pure wear & tear part and must be
checked regularly. Two different kinds of wear & tear on the cage are possible. The win-
dow in the cage has a width of 45 mm. Change the cage if this width is more than 50
mm. The second type of wear & tear is the decrease in the thickness of the cage wall
itself. Change the cage before a hole appears.
f If the blast wheel and cage are in good condition reassemble the components in the re-
verse order to that described above.
