Chapter 11 Maintenance
1. Unscrew all four of the screws (1) that secure the accu cover (see "Replacing the accu cover -
step 1" on page 116). A suitable Torx wrench (Tx10) is included in the myDatanet service kit
(206.324 ).
2. Carefully lift the accu cover.
Important note: Be particularly careful to ensure that the wires that are underneath and
connect the accu electronics to the accu cells are not damaged.
3. Loosen both of the screws (4) that secure the accu electronics and carefully remove the accu
electronics from the accu cover (see "Replacing the accu cover - step 2" on page 116).
4. Then push the accu electronics into the new accu cover and secure the accu electronics with
the screws provided (4).
Important note: Ensure that you do not mix up the screws (4) for securing the accu elec-
tronics with the screws (1) for securing the accu cover.
5. Place the accu cover back on the accu pack and secure it with all four of the screws (1).
Tighten all four of the screws crosswise so that the accu cover is affixed uniformly (ensure the
maximum permissible torque of 0.4 Nm is maintained).
11.3.3 Maintenance of the accu seal
The optional "myDatanet service kit (206.324 )" equipment is required for maintaining the accu
seal.
Important note:
l
Ensure that any impurities are eliminated.
l
The seal of the device is not guaranteed if the sensor head and accu cover are not
cleaned thoroughly.
l
If residual dirt cannot be removed from the accu cover, it must be replaced (see
"Replacing the accu cover" on page 116).
l
The seal must be protected before EACH assembly with a bead of grease from the
syringe included in the myDatanet service kit (206.324 ).
1. After removing the accu or battery pack, clean the contact surface on the myDatalog4 with a
standard cleaning cloth and cotton buds.
