8 Connect the bleeder valve (C) with a pneumatic hose, outer diameter 8 mm
(calibrated). The recommended hose length is 1.25 m. The open end of the
hose must be fed into the transparent collection container.
9 The bleeder valve (C) can now be unlocked and the hydraulic system can be
flushed using the load stroke . Load stroke must be actuated continuously.
CAUTION
Under no circumstances should the fast approach stroke be actuated, as this
would cause air to enter the hydraulic lifting system.
10 For pit jack 2S , 4.2 liters and for pit jack 3S , 12 liters must be discharged
by actuating the load lift.
11 As soon as the specified quantity has been removed, the bleeder valve is
closed first and then the operation of the load stroke is stopped
immediately.
12 Fully retract the pit jack. Make sure that the oil sight glass is half covered
when retracted. Top up with oil if necessary. (The pit jacks have an oil
reserve of at least 10 % of the operating volume, see DIN EN 1494:2009
5.5.3.6)
13 Remove the hose from the bleeder valve (C) and allow any residual oil in the
hose to run into a container.
14 Place a cloth underneath the screwed-in bleeder valve (C).
