Display Unit
• Check the surface of the outer sheath of the cable and
the connector for damage.
• Check the life of the batteries.
• If a battery life of 4 to 6 hours is indicated on the dis-
play unit, you should take a new set of batteries to the
measuring site.

nal case in a clean, dust-free room.
• If the unit is not used for a long period of time, remove
the batteries.

Maintenance
We recommend to check the concrete test hammer for
wear after 2 years at most and clean it. Do this as des-
cribed below.
The concrete test hammer can either be sent
to a service center authorized by the vendor or
else it can be maintained by the operator
according to the following description.
The items in (brackets) are illustrated in Fig. 6.2, ”Length-
ways section through the concrete test hammer”, page 16.
6.4.1
Stripping Down
Warning!
Never strip down, adjust or clean the slider
and guide rod (4) (see Fig. 6.2, page 16),
otherwise the slider friction may change.
Special tools are required to readjust it.
• Position the concrete test hammer perpendicular to the
surface.
Danger!
The impact plunger (1) generates a recoil
when it deploys. Therefore always hold the
concrete test hammer with both hands!
Always direct the impact plunger (1)
against a hard surface!
• Deploy the impact plunger (1) by pushing the concrete
test hammer towards the surface until the push
button (6) springs out.
• Unscrew the cap (9) and remove the two-part ring (10).
• Unscrew the rear cover (11) and remove the compres-
sion spring (12).
• Press the pawl (13) and pull the system vertically up
and out of the housing (3).
• Lightly strike the impact plunger (1) with the hammer
mass (14) to release the impact plunger (1) from the ham-
mer guide bar (7). The retaining spring (15) comes free.
