500 E Global Operating Instructions
Initial operation

ˆ
An indication exceeding the full load value means overloading of
the motor, whereas an indication below the full load value shows
that there is not enough abrasive fed to the blast wheel. If
necessary re-adjust the abrasive shot valve handle that operates
the shot valve or refill the hopper with abrasive.
ˆ After having blasted approx. 2 m close the abrasive shot valve,
stop the machine and check the blasted surface.
ˆ If the blast pattern is irregular it may be necessary to re-adjust
the blast pattern (see Chapter 7.5 “Setting the blast pattern”) or
select another travel speed for the machine.
When the blast head is lifted from the floor, abrasive escapes
from the sides of the blast head at high speed. If the machine is
moved with the blast head raised, the abrasive shot valve must
be closed and the blast motor must be off.
Alter the travel direction only after having closed the shot
valve.
The dust container of the filter unit must be emptied regularly.
