Proceed as follows:
1. Tighten the release nuts using a 16 mm wrench and a torque of 20 Nm (15 lb.-ft.).
2. Turn the Bubble Buster off by pressing the suitable switch.
3. Disconnect the 4 transparent hoses of the Bubble Buster, two from the cylinder and two from the pump fitting.
4. Unscrew the pump fitting and screw immediately the cap with a 2 Nm torque using a 4 mm Allen wrench.
Before using the purged ZTF system during navigation, check carefully its functioning.
1. Move the cylinder along the whole stroke, making sure that there are no malfunctions or interferences.
2. With the outboard engine in central position, push and pull the engine by acting on the motor hood: if the
system has been properly purged, the engine will not move.
3. By slightly pushing the motor hood towards starboard and, at the same time, pushing the engine towards
port by acting on the motor hood, the engine must not rotate towards port.
4. Repeat the previous check by inverting the movement directions,

TOWARDS
PORT
6. Once on the port side, leave the cylinder in this position
and wait again for a few minutes.
7. Slowly move the cylinder with the tiller handle. Repeat
the steering movement from starboard to port and the
opposite at least 3 times.
8. With the cylinder placed at the end stroke (port), push
the handle again towards port: the cylinder cannot
move, since it is at the end stroke. This push on the
handle will further expel air bubbles (keep pushing
for 10 seconds).
9. Move the cylinder slowly towards starboard and repeat
the previous operation.
10. Tighten the by-pass knob: the system will be in by-
pass off mode, neutralizing the propeller torque effect
on the throttle knob.
11. Move the cylinder slowly using the tiller handle and
repeat the steering movement from starboard to port
and the opposite at least 3 times.
12. At this stage, the system will be oil-filled and purged:
looking at the transparent hoses of the Bubble Buster,
no air bubbles should be visible. If they are still visible,
repeat the whole purging procedure again.
CAUTION
It is recommended to start the purging operation with the cylinder at the end of stroke.
