Verification of the reversing mechanism
Attention!
Beware of reversing mechanism moving parts.
Note!
These steps apply only to reversing valves that are adjustable height
wise.
Set the trigger of the reversing
mechanism in the up position, then
check by hand if the spool of the
reversing valve moves up and down
easily on approximately 1 mm. If not,
loosen the bolts behind the valve and
adjust the valve height wise.
Make sure the spacers underneath the
valve housing remain in place;
Push the trigger of the reversing
mechanism downward until it passes
mid-stroke.
From this point, the springs must force
the trigger to complete its down stroke.
If the trigger does not complete its stroke
automatically, repeat the first step.

● Open 2 ball valves located under the hydraulic power unit reservoir;
● Ensure the trigger is in position for siphoning cycle (trigger down);
● Start the pump and reverse the piston stroke manually (by pulling the trigger
up) after the first 12” [30 cm] of down stroke.
● Let the piston go up and reverse automatically.
● On the following down stroke, reverse the piston stroke manually after the
first 24” [60 cm].
● Let the piston go up and reverse automatically.
● On the following down stroke, reverse the piston stroke manually after the
first 36” [90 cm].
● Then, let the pump complete a few strokes automatically in order to lubricate
the piston seals completely.
