Further notes
• While driving, the drain valve (4.8.1) should be open (pulled out) to ensure
that the air jacks are completely retracted.
• A separate vent is accessible via a tappet in the drain valve for slowly
lowering a lifted vehicle. By pressing this tappet, the pneumatic system
can be vented in a controlled manner.
• Never use mineral oil-based cleaning agents.
• Porsche Motorsport recommends having an overhaul carried out by
Krontec after two years or 2,000 lifts.
• Check the tightening torque of the grooved nut (air jack tightness) during
normal vehicle checks.
Tightening torque grooved nut, rear 45 ± 5 Nm (33 ± 3.7 ft-lb)
Tightening torque grooved nut, front 45 ± 5 Nm (33 ± 3.7 ft-lb)
Position of the rear air jack in the mounting tube (4.8.2)
If a loose or improperly mounted air jack is detected, it must be replaced
immediately as internal damage cannot be excluded.
