Stripping Down

Warning!
Never strip down, adjust or clean the pointer
and pointer rod (4) (see Fig. 3.3, page 18),
otherwise the pointer friction may change.
Special tools would be 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 pushbutton
(6) springs out.
• Unscrew the cap (9) and remove the two-part ring (10).
• Unscrew the cover (11) and remove the compression
spring (12).
• Press the pawl (13) and pull the system vertically up
and out of the housing (3).
