Stripping Down

Warning!
Never strip down, adjust or clean the slider
and guide rod (4) (see Fig. 6.2), 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.
