5. Operation
During operating the 1-8DPS, the following additional safety instructions must be followed closely.
Before switching on the machine make sure that no-one can be endangered when the machine starts up.
Make sure that no vehicles, such as forklift trucks and other equipment run over the electric cable and the dust
hose.
5.1
Before switch on
Check if the distance from magnet to the floor is 8 – 10 mm. Check this height with aluminium strips.
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
magnetic 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 power supply cable of the filter unit with the generator. Be sure that electrical power
supply is correct.
5.2
Checking the turning direction of the blast motor
Start the machine for a few seconds by pressing the green ‘Blastmotor ON’ button.
Stop the machine by pressing the red ‘Blastmotor OFF’ button.
Check the rotating direction of the Blastmotor (indicated with an arrow).
Correcting the turning direction of the blast motor
Switch off the motor and put the main power switch to the OFF-position.
Wait for a complete standstill of all drives.
Unplug the machine from the power supply.
Rotate the inverter switch inside the mains plug to the opposite position.
Reconnect the machine to the power supply and check the turning direction of the motor again.
5.3
Switching the machine on
Before switching on the blast machine, switch the dust collector on. The dustcollector is needed to
vacuum off all the created dust and helps to cool the blast machine.
Press the green push button “Blastwheel ON” and check the rotating direction of the blastmotor. The
correct direction is given with an arrow on the housing of the motor.
If the blastmotor turns the wrong way, correct this immediately.
Select the speed using the speed control knob. (item 9 of machine description)
When the machine is traveling pull the abrasive control cable to open the magnetic valve. Observe the
ammeter. It may indicate the full load amperage. 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 the blastwheel cover a little bit clockwise. Loosen the
clamp lever for cage adjusting (item 15 of machine description) and hammer on the finger to adjust
the position. Tighten the clamp lever after adjusting.
Never adjust the cage during blasting!
