WORKING DIRECTION (FIGURE 18)
1. Carry out blasting in parallel back-and-forth tracks working away from the dust collector. Make sure the power cord and dust hose do not
become twisted. Keep an eye on the maximum cord and hose lengths and reposition if needed.
2. When the end of a track is reached, close the shot valve while keeping the blast motor running. Turn the machine around by swinging the
front end in a loop going forward.
Note:
When turning the machine around, do NOT back up. Rather, swing the front end in a loop going forward to prevent losing the bottom
shot seal and causing the front caster to swivel backwards.
3. Align the machine for the next track, reopen the shot valve and proceed to blast the new track with minimal overlapping.
4.
Repeat this process to complete the surface, moving away from the dust collector to the unblasted surface. When finished, move the dust
collector to the completed surface and blast the area where the dust collector was located.
Note:
If a fine blasting result is required, it is necessary to blast in the same direction.
TRAVEL SPEED
Selecting the right travel speed is important for achieving a good blasting result and depends on the type of surface material and desired profil
-
ing. Determine the right travel speed by observing the blasted surface and varying the travel speed during operation.
•
Slight profiling on concrete requires a higher travel speed than coarse profiling.
• Blasting on steel requires a very low travel speed of the machine.
FIG. 18
CAUTION:
TAKE CARE NOT TO TRIP OVER THE POWER CORD AND DUST HOSE.
CAUTION:
CLOSE THE SHOT VALVE BEFORE TURNING THE MACHINE AROUND TO MAINTAIN AN EVEN BLAST PATTERN AND AVOID
DAMAGING THE FLOOR.
