TOOL APPLICATIONS
• De-rusting and cleaning metals.
• Removing paint, rust and dirt.
• Peening of welded joints.
• Cleaning castings.
• Cleaning welding slag.
• Removing barnacles.
Rustibus® 20 Needle scaler is pneumatically driven and requires 12 CFM / 340 litres per minute/6-8 Bar 87-116 psi. The machine is easy to operate and leaves the surface clean to St 3+++ (SSPC-SP11+++).
The machine is adjusted to a proper BPM when it leaves the Rustibus® factory. If maintenance is done on
the air motor, make sure the BPM is not exceeding 4600 BPM.
Always disconnect the air supply before dismantling the Rustibus® 20 machine.
NEEDLE / CHISEL INSTALLATION
Always close the air supply to your Rustibus® 20 and disconnect the airline before you install, remove
or adjust the needles / chisel or before carrying out any maintenance.
Installing the needles into your Rustibus® 20 could not be easier and is done in a few simple steps.
1. Lift up the lever of the Retainer on the side of the Rustibus® 20.
2. Slide in / pull out the Needle Driver into / from the Rustibus® 20 making sure the cut--out
notch in the Needle Driver is facing upwards.
3. You can then release the Lever on the side of the Rustibus® 20.
The lever on the side of the Rustibus® 20 is connected to the Retainer. This in turn ‘Retains’ holds the Needle Driver / Chisel is place. The Retainer rests in the cut-out notch of the Needle Driver / Chisel when they
are installed in the Rustibus® 20.
On the side of the Needle Tube there is a cut –out section with a series of notches.
The cut—out on the Needle Tube is meant to fit over the lever of the Retainer. The lever then fits into the
first of these notches and the following notches allow you to adjust the length of the needles as they
ware down during use.

RUSTIBUS® 20 - DISASSEMBLY
1. Disconnect your air supply and remove all attachments.
THE NEEDLE ATTACHMENT
2. Holding the Needle Tube (020-779) in one hand and the Backhead in the other. Push and twist the
Needle Tube until the lever of the Retainer (020-956) is free from the Needle Tube.
3. Slide the internal parts of the Needle attachment out of the Needle Tube.
4. Pull the tab on the Retainer up on the tool and remove the Needle Driver (020-045)
THE SCALER BODY
5. Using a vice, clamp the Rustibus® 20 in an upright / vertical position with the front of the tool, facing
upward. Clamp using the flats on the Backhead.
6. Using a pair of internal expanding pliers, expand the Retainer clip.
7. Remove both the Retainer Buffer (020-527) and the Retainer (020-956)
8. You should now remove the Rustibus® 20 from the vice and clamp the Barrel assembly in the vice in
a downward facing position, Making sure you clamp the tool using the flats on the side of the Barrel.
9. Using a wrench you must then loosen the Backhead lock ring. This will allow you to remove the entire
Backhead Assembly.
10. Removing the Barrel unit from the vice you are now able to slide the Valve assembly and Plunger
(020-373) from the Barrel.
11. Should you wish to check the Throttle valve, remove the Throttle valve cap (020-207 and Cap Gasket
(020-636). Lift out the Valve Spring (020-078) and Valve (020-782). Replace the ‘O’ ring if worn or

Support the Valve Block (020-508) under an arbor press. Take both V.B. Dowel pins (020-126) and fit
them into the ‘blind holes’ in the Valve Block until they are fully in, they should press against a should
at the bottom of the holes.
The Flutter Valve (020-196) can then be placed in the recessed centre of the Valve Block.
You are now able to fit the Valve Block Button (020-173) on to the Valve Assembly. Make sure the
Blind holes of the V.B. Button (This are the holes that are parallel to the axis of the part) line up with
the Dowel pins.
With the Valve Block facing upwards, place the Valve assembly on a small round support that has a
smaller diameter than the inside of the Barrel. You can now place the Plunger (020-373) on to the
Valve Block. The protrusion on one end of the Plunger should now also be facing upwards.
The Cylinder Sleeve can now be set in place over the plunger. This is then followed by the Tool Nose
(020-363), do not forget to set in place the Tool Nose Key. (020-801)
The Barrel (020-343) can now be slipped over the entire assembly, until the assembly sits firmly in
inside the Barrel. With a firm grip on the support fixture and Barrel, turn the whole unit over. (If you
assemble the units in this way it will ensure that the Value assembly does not separate during
installation.
With the front of the tool in a downward facing position, clamp the Barrel unit vertically in a vice.
Using the flat clamp points.
Remembering to fit the Backhead Positioning Spacer (020-947), screw the Backhead Lock Ring on to
the (020-882) Backhead Assembly (020-851). (Make sure that the taper of the lock ring is facing the
front of the front of the Backhead Assembly.
The Backhead Assembly can now be screwed on to the back of the Barrel Assembly. Use a wrench to
tighten the Backhead Assembly. Screw down and tighten the lock ring against the Barrel.
Turning the whole unit up side down in the vice so that the front of the unit now faces upwards,
place the Retainer (020-956) and Retainer Buffer (020-527), in the cut out section at the front end
of the Barrel unit. You are now able to expand the Retainer Clip (020-554) and place in position over
the Retainer Buffer and Retainer.
THE NEEDLE ATTACHMENT
11. Begin by sliding the correct number of needles into the Needle Holder (020-046). The large ends of
the Needles will fit into the recessed holes in the back of Needle Holder. Slide the Needle Spring
(020-044) over the needles and up to the needle holder.
12. Place the needle unit into the rear of the Needle Tube (020-779).
13. Lift the lever of the Retainer (020-956) up on the Rustibus® 20 and then slide in to place the Needle
Driver (020-045).
14. Holding the Needle Tube unit in one hand and the Backhead Unit in the other, push and twist the
Needle Tube unit until the lever of the Retainer is set in a notch on the Needle Tube.
