Introduction
General The Martin®DT2S Reversing Cleaner is used in conjunction with a head
pulley primary cleaner such as a Martin®Primary Cleaner.
The Martin®DT2S Reversing Cleaner contacts the belt as it leaves the head
pulley or another accessible position on the return belt with proper support.
The blades of the Martin®DT2S Reversing Cleaner, when tensioned, lay in
the direction of belt travel giving a negative angle and presenting no snag or
danger to the belt or splices.
The Martin®DT2S Reversing Cleaner can be supplied or retrofitted with a
variety of cleaning blades.
If the material-handling process or product could be affected by
contamination from the use of these belt cleaners, the user is responsible for
taking the necessary steps to prevent contamination. Consult Martin
Engineering or a representative for alternate belt cleaners or belt cleaner
locations to use where contamination may be an issue.
Installations
Without
Chutework
These procedures were written for equipment that is being installed on

2. At the selected mounting positions, cut the cleaner access slots and drill
the mount holes in each side of the chute. Dress and de-burr the holes and
cutouts.
3. If belt width is 54” or larger, replace 1-3/4” long spring, upper flat washer
and UHMW spring retainer with 2” long spring and 3/4” washer included.
4. Fit operator side mount bracket to the chute wall. Bolt mount to the chute
wall.
5. Repeat for far side mount bracket.
6. Fit the cleaner mainframe to the mounts. Slide the mainframe into one of
the mount brackets, through the cutout in the chute wall, then through the
cutout and mount on the opposite side.
NOTE
The mainframe has holes at one end. This is the end that fits
to the operator side mount.
7. Align the end of the mainframe with the outer edge of the operator side
mount bracket and refit the locking screw, taking care to fit the air line
bracket under the screw (air tensioner models only). At the far side mount,
tighten the lock screw onto the mainframe.
NOTE
The mainframe in most cases will have excess length. If
required, this excess can be trimmed from the far side end.
8. Slide the blade cartridge onto the mainframe from the operator side. If the
cartridge is too long, excess can be trimmed from the non-operator end.
If not already done, fit the cleaning blades to the cartridge. Center the
blades to the belt by loosening and re-positioning the blade end stops.
Insert the blade cartridge retaining pin.
9. With the cleaner tensioner in a fully retracted position, the cleaning blades
should be approximately .5 in.–.75 in. (13 mm–19 mm) clear of the
underside of the belt and this distance should be equal across the width of
the belt.
10. If necessary, loosen and adjust the mounts up or down to achieve this
clearance.
11. Once all clearances are correct, thoroughly check all mounting and
locking screws to ensure they are tight and the cleaner is secured.
12. For the air-tensioned model only, connect the air tube to the fittings in the
far side airbag on the underside of the mount bracket. See Figure 5.
13. Pass the tube through the mainframe. (Make sure tube is located
underneath handle.) Connect the tube to the tee air fitting in the operator
side airbag adjusting the tube length to suit by cutting.
14. Connect the other side of the tee fitting to the incoming regulated
compressed air supply or to the outlet of air regulator kit, if used. Connect
the plant air supply or air supply kit to the inlet side of the regulator kit.

Table II. Recommended Spring Tension and Air Pressure
*For belt widths 54 in. and above, replace 1-3/4” long spring, upper flat washer and UHMW spring retainer
with 2” long spring and 3/4” washer included.
Adjusting the Air
Tensioner
The air tensioner utilizes an inflatable air bag on each cleaner mount to
provide the force to adjust the blades against the belt. Cleaner adjustments and
correct force are automatically applied by simple air pressure control. See
Figure 5.
1. Adjusting the air-tensioned Martin®DT2S Reversing Cleaner requires
supplying air at the appropriate pressure to the tensioner air bags. Refer
to Table II for recommended air pressure.
2. If using the Air Tensioner Air Regulator Kit, connect the plant air line to
the lockable ball valve on the outside of the enclosure. Turn on the air
supply and the ball valve to pressurize the tensioner. The cleaner will
automatically rise and the blades will contact the belt.
3. Adjust the pressure to the required level by unlocking and adjusting the
regulator inside the regulator kit. The regulator is self-relieving so the
pressure will stabilize. (It is advisable to wait a short while after each
adjustment to allow excess pressure to bleed.)
4. Once the correct pressure has been achieved, relock the regulator and
close the lid on the enclosure.

Blade Servicing 1. Undo tensioner and visually inspect blades.
a. If blades are clean and not excessively worn, re-tension cleaner.
b. If material buildup is still present or blades are worn excessively,
proceed.
2. When fully retracted, simply remove the retaining pin securing the blade
cartridge to the operator end of the mainframe. Grasp the handle and pull
the blade cartridge off the mainframe and away from the mount bracket.
Completely remove the blade cartridge from the mainframe and place it
in a suitable position for maintenance work to be carried out.
3. Clean and inspect the blades. If blades are excessively worn, replace with
new blades. Remove the blades from the cartridge by removing one of the

end stops. Slide the blades out of the cartridge and replace by sliding in
new blades. Ensure the blades face in the correct direction. Re-fit the end
stop. These prevent belt damage by supporting the belt at the edge of the
cleaning blades. If removing both end stops, first mark their position in
the cartridge to ensure correct positioning of blades on re-assembly.
4. Re-install blade cartridge onto the cleaner mainframe and re-fit the
securing pin at the operator side. Re-tension the cleaner.
5. Remove equipment from service if there is any indication it is not
functioning properly. Call Martin Engineering or representative for
assistance. Do NOT return equipment to operation until the cause of the
problem has been identified and corrected.
