3 Installation
Do not remove, add, or change any of the components
in the instrument unless these changes are described
and specified in a manufacturer
’s official information.
Otherwise the manufacturer
’s guarantee becomes invalid,
and the certification for use in explosion-hazardous
locations (if provided) is no longer valid.
3.1
Protective roof / deflector
If at all possible, place the MaihakMBA unit in a position
where falling bulk material will not directly strike onto the
shaft or the paddle.
For heavy bulk materials that could damage the shaft or the
paddle:
If required, install a stable deflector or protective roof in
the container which protects the shaft and the paddle
against direct impact of falling bulk material.
3.2
Assembly (if required)
If shaft, paddle, and protective tube (if provided) were
shipped dismantled (for safe and easy transport):
Install the shaft:
Guide the top end of the shaft into the
shaft sleeve of the unit head. Use a split-pin to connect
both parts (push it through and spread it out).
– With two-
part shafts: Join both parts of the shaft in the same way.
Assembling the protective tube
(for divided protective
tubes): Take the locking screws out of the connecting
coupling sleeve. Screw one of the protective tube parts
into the coupling sleeve
– up to about the middle of the
coupling sleeve. Then screw-in the other part from the
other side and firmly attach both parts of the protective
tube.
–
Recommendation:
Now make two small
countersunk holes in the coupling sleeve, which will fix
the position of the locking screws (use a max. 3.2 mm
diameter drill guided through the screw holes of the
coupling sleeve).
– Put in the locking screws and tighten.
Install the protective tube
(for units with a protective
tube): Apply a threadlocking adhesive (such as »Loctite«)
to the thread of the protective tube and screw the
protective tube into the threaded sleeve, as far as it goes.
Shortening the flexible cable shaft
(if required): Remove
the tensioning weight from the end of the cable (undo the
locking screw and pull out the cable). At the place where
the cable must be cut, wrap some adhesive tape firmly
around the cable, to protect against wire particles
shooting from the cable. Wear protective goggles/
glasses. Then cut the cable with a suitable wire cutter or
a cutting disk. Remove the adhesive tape and attach the
tensioning weight again.
Install the paddle:
Guide the flat end of the paddle into
the slot of the shaft and attach it with the split-pin
provided (push it through and spread it out).

If the bulk material is heavy or can form large clumps:
Install a stable protective roof within the container to
shield the shaft (and the extension arm) from the weight
of the bulk material.
Provide sufficient space between protective roof and
paddle to make sure that the bulk material can reach the
paddle.

●
It may be necessary (or advantageous) to install the
paddle at the very end of the installation procedure.
●
Recommendation:
Apply a threadlocking adhesive
(such as »Loctite«) to all the locking screws.
