SERVICE INSTRUCTIONS
23) Check that the bleed valve (P) and the shut-off valve
(Q) are closed (turn in a clockwise direction). The
release pin (S) should be inside the M6 thread on
the armature (turn knob (O) in a counter-clockwise
direction).
24) Check that the M6 thread at the end of the armature
is equipped with the sealing washer (R).
For G 1/8" port: connect G 1/8" adapter 3014016 to
the replenishing armature.
25) Connect the replenishing armature to the gas spring,
by means of knob (N), turned in a clockwise direction.
26) Open the nitrogen bottle using knob (Z). Regulate to
the desired charging pressure with handle (U) on the
regulator (V).
Note! Maximum charging pressure is 150 bar
(2175 psi) for all models except HT 750, 120 (1712
psi).
The manometer (X) shows the charging pressure and
manometer (Y) shows the bottle pressure.
27) Open the shut off valve (Q) slowly on the armature
and charge as slowly as possible. Never lean over the
gas spring during the charging. After charging, the
manometer (T) shows the pressure supplied to the
gas spring.
28) After charging, empty the gas inside the armature
by first closing the shut off valve (Q) and opening the
bleed valve (P) until the gas is released.
29) Unscrew the armature fully using knob (N). Check to
make sure that the valve does not leak. If the valve is
leaking, it must be replaced.
For safety, never lean over the valve!
30)
Fit the cover screw (J) on the gas spring, tighten with
a torque of max. 5 Nm (for G1/8" cover screw). Note
that it has a sealing function and must always be
fitted and tightened.
31) When finished with the armature, empty the gas
inside the armature and hose by closing the nitrogen
bottle using knob (Z) and opening bleed valve (P) and
shut off valve (Q) until all gas is released.
