7.6 Adjusting Magnets and Seals
The adjusted height of the magnetic seals should be set equally at about 12 mm and parallel to
the surface.
For the height adjustment, a 12mm stainless-steel strip (B) is shifted below the magnetic seals.
Adjust the height as follows:
1. Lift the machine with the lifting cylinder, pulling
back the lever (A).
2. Loose the two adjustment screws (C).
3. Lower the machine onto the stainless-steal strip,
as the front wheels smoothly touch the ground.
4. Tighten the screws until they stop at the wheel
bracket and then secure their positions with the
lock nut.
5. Finally lift and lower the machine and check the
distance between floor and magnets.
• The setting depends on the structure of the surface to be treated, in general the rougher the
surface the lower the setting.
• Working on steel means to set it down as far as possible.
• The height of the brush seals should be maximum 1 mm above the surface. The adjustment is
possible within the slots of the seal elements.
Basic settings of the blast head after changing of blasthousing or rebound:
1. Adjust the height of 82 mm between underside
of the frame and the surface.
2. Align the blasthead in a horizontal position with
a distance of 12 mm between magnets and
surface.
3. Adjust the height with the setting screws, two
at the underside of the Frame (E) and two on
the inner side of the rebound (G), securing its
position with the lock nut.
4. Finally tight the four fixing screws (D+F).
7.7 The Belt Drive
The belts are designed for the installed drive power. Forcing the drive to produce a higher output
by overtensioning the belts results in belt breaks, bearing damage, and lower efficiency. A low belt
tension results in slippage causing an increased belt temperature and premature destruction of the
belts.
Temperatures exceeding 70°C for a long period reduce the service life and performance of the
belts. The grooves of the belt pulleys must be free from rust, grease, dirt, and any visible damage.
