CHECKING THE GAS PRESSURE
Inspect the nitrogen gas pressure every 100 hours.
Note:
The gas charge determines
the striking power of the hammer. If the gas charge is low, the energy produced by the
hammer will be low.
PROCEDURE
1. The gas pre-charge is measured with
no preload
on the tool. Remove the tool or
position the hammer with the tool fully extended. THE HAMMER MUST NOT BE
RESTING ON THE POINT.
2. Remove the charge valve cap (M1).
3. Turn the NPK charging adapter T-
handle (g2) full counterclockwise.
4.
MODELS GH06, GH07, GH1, GH2/GHS2
Remove plug (g12). Install adapter (g13)
part no. 30604100 into the female port on
the gas head. Install NPK charging adapter
(g1).
4.
MODELS GH3, GH4 and GH6 Only
Install the NPK charging adapter (g1)
on the hammer charge valve (M).
Remove the valve cap only, not the charge valve assembly!
5. Tighten the charging adapter cap (g6).
