ASSEMBLY
Step 1: Blasting hose
- Completely unwind the blasting hose and, if necessary, cut it to desired length.
- Fit a claw coupling to one end of the blasting hose and fasten it with the provided hose
clamp. Make sure the connection is tight.
Step 2: Assembling nozzle end of the blasting hose (if not already assembled)
- Screw the plastic nozzle holder onto the other end of the blasting hose with coarse thread
end first (fine thread end is for the nozzle). Make sure the nozzle holder is screwed all the
way up to the mark inside the nozzle holder, otherwise it will wear very quickly from the
inside due to sandblasting. Note! To screw the nozzle holder onto the blasting hose re-
quires a lot of effort.
- Screw the nozzle on the nozzle holder. Make sure the connections are tight and
function properly.
Step 3: Mounting the blasting hose to the tank
- Fit the claw coupling on the blasting hose to the claw coupling located underneath the
tank, and lock them together with two lock pins provided. This is to prevent the coupling
from opening unintentionally.
Step 4: Electrical connections
- Release the cable bundles on the side of the appliance by carefully cutting the cable ties.
In order to avoid transport damages, the appliance is delivered with electrical connec-
tions undone.
- Connect the plug to the electric cable.
- Position the microswitch (microswitch is low-voltage) to desired place on the blasting
hose (usually near the nozzle), and fasten the microswitch and its electric cable on the
blasting hose from its whole length with electrical tape. Make sure to leave enough length
for the blasting hose and electric cable so that they can move freely and will not tighten
at all during blasting, otherwise the electric cable will be damaged. Note! If so desired,
the microswitch may also be installed to a foot pedal (not included).
Before you begin working, thoroughly go through and inspect each connection to
make sure they all are tight and properly seated.
OPERATION
Sand
- The kind of sand you choose will greatly influence the amount of time required to clean a
given surface area. Sandblasting materials include silicon carbide, alumina, silica sand,
bank sand and beach sand. However, note that bank sand and beach sand, even if
washed, will still contain shell, coral and organic materials that absorb moisture readily,
causing clogging of the sand metering valve.
- When reusing sand, remember that it does wear out during sandblasting. The sharp edg-
es become rounder causing the sand to be less effective.
- Always use dry sand.
