5. Operating
During operating the 500HSH, the following additional safety instructions must be
followed closely.
Before switch on
Check the distance from brush sealing to the floor. This may be max. 1 mm.
Fill the separator equally with the selected abrasive up to the bottom of the
separator tray. The abrasive valve must be closed whilst doing this.
Connect the blast machine and filter unit with the dust hose. This connection must
be reliable.
Connect the hydraulic power supply hoses of the filter unit and blast machine with
the power pack. Be sure that hydraulic couplings are connected according to the
labels on the hoses.
Switch on the machine
Switch unit the power pack (see manual of the power pack)
Before switch on the blast machine, switch on the filter unit.
Select the speed using the speed control knob. (item 5 of machine description)
Switch on the blast motor (item 8 of machine description)
Switch on the fan motor (item 9 of machine description)
When the machine is traveling pull the abrasive control handle to open the
abrasive valve. Observe the manometer. It may indicate the max pressure. After
having blasted aprox. 2 m, close the abrasive valve, stop the machine and check
the blasted surface.
If the ‘hotspot’ is too much on the right, turn clockwise the cage a little bit. Never
adjust the cage during blasting.
Switch off the machine
Close the abrasive valve
Stop the drive motors
Turn off the blast wheel motor
Turn off the fan motor
Switch off the filter unit.
Switch off the power pack
After switch off the power pack the hydraulic hoses are still under high pressure. It
is important to switch on the filter unit or blast motor. The filter unit or blast
machine will work for seconds. This will bring down the hydraulic pressure in the
hoses to zero.
Disconnect the hydraulic hoses of the blast machine and filter unit.
Wait for standstill of all drives before any inspection or maintenance works are
started.
