Cleaning; Storage & Transport; Maintenance - Scheppach SBT-80 Translation Of Original Instruction Manual

• Pressure and nozzle selection: The blasting pres-
sure and nozzle selection must be matched to the
surface to be treated in order to avoid damage and
deformation.
• Correct blasting direction: The blasting direction
should be perpendicular to the surface to ensure
even removal.
• Keep your distance: The distance between the
blasting nozzle and the surface should be kept con-
stant to avoid damage.
• Disposal of the blasting material: Sand released
during blasting may contain pollutants and should
therefore be disposed of properly.
10.8 Releasing the pressure (Fig. 12, 13)
1. After the work process, first close the blasting ma-
terial shut-off valve (12) so that no blasting material
remains in the lines.
2. Close the main supply line shut-off valve (18).
3. Switch the compressor off.
4. Keep the lever (6) on the blasting gun (8) pressed
until all the air has escaped from the lines.
5. Slowly open the seal (4) by turning it anti-clockwise
until the pressure relief holes are visible. This allows
the remaining pressure to escape from the container.
NOTE! If you notice air escaping when opening the
seal (4), wait until the pressure is completely released
before opening the seal (4) completely.
10.9 Disconnect compressed air supply (Fig. 1)
1. Close the main supply line shut-off valve (18).
2. Switch the compressor off.
3. Disconnect the compressed air hose from the
compressed air connection (19).

11. Cleaning

m Attention!
Depressurise the product before carrying out any
cleaning or maintenance work! Danger of injury!
• Wipe the product with a clean cloth.
• We recommend that you clean the product directly
after every use.
• Clean the product at regular intervals using a damp
cloth and a little soft soap. Do not use any cleaning
products or solvents; they could attack the plastic
parts of the product. Make sure that no water can
penetrate the interior of the product. Water penetra-
tion increases the risk of rust formation in the product.
12. Storage & transport
12.1 Storage
m Attention!
Disconnect the compressed air hose from the com-
pressed air connection.
m Attention!
Store the product upright!
Store the product and its accessories in a dark, dry and
frost-free place that is inaccessible to children.
The optimum storage temperature lies between 5 and
30 ˚C.
Store the product in its original packaging. Cover the
product to protect it from dust or moisture. Store the
operating manual with the product.
12.2 Transport
The product can be tilted it up by means of the handle
(1) so that it can be transported on the wheels (8).
The product must be secured against tipping and slip-
ping during transport in vehicles in order to prevent
damage and injuries.

13. Maintenance

m Attention!
Depressurise the product before carrying out any
cleaning or maintenance work! Danger of injury!
• The product shall not be operated if the pressure
vessel (5) is damaged or rusty. If you discover dam-
age, please contact the customer service workshop.
13.1 Safety valve (Fig. 14)
The safety valve (2) is set to the maximum permissible
pressure of the pressure vessel (5). It is not permitted
to adjust the safety valve (2) or to remove the connec-
tion lock (2b) between the drain nut (2a) and its cap
(2c).
In order for the safety valve (2) to function properly
when needed, it must be actuated every 30 operating
hours and at least 3 times a year. Turn the perforated
exhaust nut (2a) anti-clockwise to open it and use your
hands to pull the valve rod outwards over the perfo-
rated exhaust nut (2a) to open the outlet of the safety
valve (2). Now, the valve audibly releases air. Then,
tighten the exhaust nut (9a) clockwise again.
