Performance Check

If possible, carry out the performance check every time
before you use the device, however at least every 1000
impacts or every 3 months.
• Place the testing anvil on a
hard, smooth surface
( e.g. stone floor ).
• Clean the contact surfaces
of the anvil and the impact
plunger.
• Perform about 10 impacts
with the concrete test ham-
mer and check the result
against the calibration value
specified on the testing anvil.

hammer ( model N/L shown )
Proceed as described in "Maintenance
Procedure" on page 16 if the values are not
within the tolerance range specified on the
testing anvil.
