2. Machine description

The Blastrac 1-8DM is a downward blasting machine with a closed abrasive circuit, designed for the
pre-treatment of horizontal surfaces. The bouncing impact of metallic abrasive onto the surface to be
treated, thoroughly removes surface contaminants, coats of paint, seal ants and thin coatings.
A suitable dust collector must be connected to the machine in order to separate the dust from the
abrasive. A specially designed dust collection system ensures dust-f ree operation of the machine and
clean air in the workspace.

5. Operation

Controls

The ON/OFF switch (1) controls the blast
wheel motor. The shot valve lever (2)
controls the amount of abrasive going into
the blast wheel. Observe the Ammeter (3) to
ensure that the proper amount of shot is
being let through the shot valve.

Handle Adju st m ent

Adjusting the height of the handle is possible
by loosening handle adjustment levers (1)
and adjusting the handle to the desired
height.

Close Blasting Mode

To work as close as possible to the wall you
can invert the right-side handle (1) and rear
wheel (2). The handle grip can be screwed
into the opposite side of the handle and the
rear wheel can be screwed into the opposite
side of the wheel bracket.

During operation of the 1-8DM, the following additional safety instructions must be followed closely:
Before switch on

 Check if the distance from magnet to the floor is approx. 1/4”. Check this height with a luminum
strips.

 Check the distance from brush sealing to the floor. This may be max. 1/32”.
 Fill the separator equally with the selected abrasive up to the bottom of the separator tray. The

magnetic valve must be closed while doing this.

 Connect the blast machine and dust collector with the dust hose. This connection must be reliable.
 Connect the power supply cable of the dust collector to a power source. Be sure that electrical power

supply is correct.
Switch on the machine

 Before turning on the blast machine, turn on the dust collector.
 Turn power switch to “ON” and check the rotating direction of the blast motor. The correct direction is

given with an arrow on the ho u sing of the motor.
 With the machine in motion pull the abrasive control cable to open the magnetic valve. Observe the
ammeter, to ensure proper amperage. After having blasted approx. 6’, close the abrasive valve, stop
the machine and check the blasted surface.
 If the ‘hotspot’ is t oo much on the right, turn the cage slightly clockwise. Loosen the cage clamps and
turn the control cage in the suitable direction. The cast grooves on the control cage sho w the pos ition
of the control cage opening. Tighten the nuts of the ca ge clamps after adjusting.
