tappet and pull it in and out for three times to
spread the grease.
Push the tappet spring onto the Tappet Centering
Screw BY.
Push the tappet rod through the tappet spring
into the fluid box. Make sure the tappet goes
through the tappet sealing.
Screw the Tappet Centering Screw BY completely
into the fluid box (torque 100 – 140 cN.m). Use
MDT 303 - Nozzle Insert Changing Tool.
The three small pins of MDT 303 have to fit
exactly into the three holes of the Tappet
Centering Screw BY. Turn the MDT 303 clockwise
while pressing it down slightly to the fluid box.
Combine the MDT 303 with MDT 327 for a better
leverage.
Alternatively, you can use the MDT 306 with
BitVM-B.
Step 7 (nozzle insert)
Use tweezers to pick up the nozzle insert and to
place it onto the fluid box body. Use the small
hole of MDT 327 to press the nozzle insert to
make sure the insert sits flat.
Step 8 (nozzle fixation nut)
Screw the nozzle fixation nut clockwise onto the
fluid box using the MDT 327. Alternatively use the
MDT 306 - Torque Wrench Tool VM with Bit
Hexagon Socket (torque 150 – 180 cN.m).
Step 9 (adjust screw)
Turn the adjust screw completely in the direction
“open” using the MDT 327.
Step 10 (fluid box)
Push the fluid box carefully in a 45° angle onto
the valve.
Make sure that the fluid box sits correctly inside
the valve and touches the frame. There will be a
resistance due to a spring inside the valve.
Straighten the fluid box until it latches in.

Optional positions
The bayonet fluid box has three locking positions
(1: -90°, 2: 0°, 3: +90°) in which the valve can be
operated. To fix in locking position 1, mount the
fluid box at position a. To fix in locking position 2
or 3, mount the fluid box at position b. Currently,
no cartridge holder is available for locking
position 1 and 3.
Perform the adjust
You need to perform the adjust now. For details
of the adjust process, see paragraph 6.5,
page 52.
After the adjust is successfully completed,
continue with the following steps.
Step 11 (cartridge holder)
Push the cartridge holder onto the top of the
valve body, so that the two pins of the cartridge
holders sit into the holes of the valve body.
To fix the cartridge holder, screw in the screw of
the cartridge holder (torque 25 – 30 cN.m). You
need the MDT 329 or a Hexagon Key 2 mm.
Depending on the size of the cartridge, you have
to select the correct cartridge holder.
Step 12 (cartridge)
Push the cartridge into the cartridge holder and
screw it onto the fluid box (clockwise).
Step 13 (Adapter for compressed air)
Screw the Adapter for Compressed Air onto the
cartridge (clockwise).
Make sure it sits tightly.
