Increase operational reliability through
preventive measures
The most common problem for a user with their
blasting equipment is that production capacity
decreases. A well-maintained blasting cabinet will
be able to provide the user with many years of
constant service. When production decreases, the
operator can usually find the cause of the problem
by checking the following:
1. Air supply. If the pressure gauge shows a
satisfactory unloaded value (the blast gun is not
activated), activate the blast gun and check the
pressure gauge, if the pressure drops
significantly it indicates that the air supply is not
sufficient or obstructed. Clean filters and check
humidity traps and hoses including connections
back to the compressor. Use a pressure gauge
to check the pressure along the line or replace
the blast cabinet regulator if it shows incorrect
values.
2. Blast gun. The nozzle wears out eventually.
Replace it with a new one when the dimension
has increased by 1/16 of the original size or if
it has worn unevenly. Adjust if necessary for
different blast media and conditions. A correctly
working pistol draws 38 - 43 cm / Hg on a
manometer.
3. Dust collector. (Not included in this model.)
Insufficient ventilation in the cabinet results in
reduced efficiency from the blast gun nozzle and
reduced overview of the work in the
cabinet. Use the dust collector shaker function
after approx. 20 - 30 minutes of use or after
each use (more often when the blast media has
worn out). Empty the container at least once a
day. Remove the filter and blow regularly with
compressed air, so that the dust collector can
work efficiently. Replace the filter if necessary.
4. Blast media. Use high-quality blast media with
a size adapted to the task. Blast media that
contain quartz particles are a health hazard.
Inhaled quartz dust can cause diseases, e.g.
silicosis which is an incurable lung disease. It
takes a long time before silicosis appears.
Therefore, it is important to protect yourself
from the dust from the beginning. Moisture in a
dirty blast media can cause an emergency stop.
Store the blast media in a dry place and top up
with the appropriate amount. The blast media
should be at a level about 15 cm above the
intake pipe, if you have less, it will be
contaminated and consumed faster. However,
the less you have in the system the less you
need to replace.
5. The path of the blast media. Replace hoses
that show signs of soft spots or show signs of
vacuum cleaner, place the spring on the outside,
adjust with the nut how far in you push the rod.
Connect the connection cord to the cord from the
left side of the lamp housing.
9. Check and retighten all nuts and bolts.
10. Insert left and right grid. The right grid has a cut
corner. Pull the hoses through the opening.
11. Connect the plug to a grounded electrical
outlet. Press the power switch, the lighting comes
on and the vacuum cleaner starts.
12. Fill with a fair amount of blast media,
approx. 1 sack (25 kg). Too much blast media can
impede flow.
General
1. Preparations before blasting. All parts to be
blasted must be free of oil, grease and moisture.
Make sure the parts are dry before placing them
in the cabinet.
2. Pressure. Normal working pressure is between
3.5 to 5.5 bar. Up to 8.6 bar can be used, but at
such a 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 at the object. Let
the ricochets that face the back of the cabinet.
Do not hold the gun at a 90˚ angle to the object
as the blasting material will then bounce back
against the gun and reduce the blasting jet. It
also wears on the parts of the pistol and on the
sight box. 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.
Never blast with the cabinet door unlocked or
open. Always remove the air connection during
maintenance and service of the appliance.
4. Blast media. The blowing media must always
be of good quality and dry. Moisture causes the
blast media to flow less and clog intake pipes,
hoses and containers.
5. The size of the nozzle. By increasing the
diameter of the nozzle, the felling can be
increased significantly, but this requires
increased air flow (the compressor must be able
to provide this).
