About blasting
1. Preparations before blasting. All parts to be pa-
inted must be free of oil, grease and moistured.
Make sure that the parts are dry before blasting
them.
2. Pressure. Normal working pressure is between
3.5 to 5.5 bar. Up to 8.6 bar can be used, but
such high pressure destroys certain blasting
materials such as glass balls. Normally the
pressure is set to 5.5 bar, this is suitable for
most materials, for materials such as steel,
aluminum or fragile surfaces you start at a lower
pressure and increase if necessary until you
reach a desired effect.
3. The angle and distance of the blasting gun.
Aim the gun at a 45° to 60° angle towards the
object. Let the ricochets be directed away from
the object. Do not hold the gun at a 90° angle to
the object as the blasting material then bounces
back against the gun and reduces the blasting
jet. It also wears on the parts of the gun. Keep
the gun at a distance of about 15 cm.
Warning. The pistol must always point away from
the operator towards the object to be blasted.
Always remove the air connection during
maintenance and service of the appliance.
4. Blasting agents. The blasting agent must
always be of good quality and dry. Moisture
causes the blast material to ow less and clog
intake pipes, hoses and containers.
5. Nozzle size. By increasing the diameter of the
nozzle, the felling can be increased signicantly,
but this requires increased air ow (the
compressor must be able to provide this).
Maintenance
1. The blasting gun. After 10-12 hours of use,
check the nozzle. If the nozzle wears unevenly,
turn it 1/4 turn after 10 hours of use.
2. Lump formation of blasting agents. Lump
formation is caused by moisture in the air
supply or from parts that are greasy or oily.
Ifleft untreated, the blasting agent will ow
unevenly and eventually clog the intake manifold
or gun. Check the air supply, install an effective
moisture trap if necessary. Degrease parts to be
blasted properly before blasting them.
3. The blast gun drops in pressure. Set the
regulator pressure to 5.5 bar, activate the blast
gun and check the pressure gauge, if the
pressure drops signicantly it indicates that the
air supply is not sucient. This may be because
the hose has too small a diameter, a reducing
quick coupling, a clogged lter or a compressor
that does not provide sucient ow. The air
hose should be 1/2 ”or larger.
4. Poor ow of blasting agents. Check for
moisture, install microlters if necessary,
replace damp blasting agent and clean hoses
and nozzles. Look for any holes in the hoses,
replace if necessary.
Dirt in the blasting agent, be careful not to put any
paper in the agent, this easily causes nozzles and
hoses to become clogged. Replace or sift the
blasting agent.
Sandblasting
WARNING: Always wear a blower hood and
approved protection, goggles, heavy gloves, shoes
and clothing. Inspect each connection and make
sure all are tight and well sealed.
WARNING: This machine is not intended for use
with silicon-based abrasives. Silicon-based
abrasives have been linked to severe respiratory
diseases.
Filling the abrasives
1. Loosen the compressed air connection hose.
Before opening the tank, make sure that it is
not pressurized and the air pressure gauge is
set to ”0”.
2. To release the pressure from the tank, push in
the blower gun lever until all air is released.
3. Check that the abrasive is dry and clean so that
it does not clog valves and hoses.
