Safety Check; Warning Lights - Williams Turbojet 285 Owner's Handbook Manual

New Engine Break-in Period
Textron Motor GmbH recommends that during the first five hours of operation, you should
not operate the engine over 6,000 RPM. This protective running-in has a positive effect on the
engine's lifespan.
Fuelling
As part of its pre-delivery inspection your new Turbojet has been fully tested and drained
of fuel.
• Ensure ignition is in OFF position.
• Remove seat cushion to expose filler cap.
• Re-fuel in a ventilated area.
• Do not overfill the tank; be careful not to spill fuel.
• Tighten fuel cap securely after re-fuelling.
• Open engine hatch and inspect bilges after re-fuelling.
• The filler cap has an integral breather.
Do NOT hose around the fuel filler area as water may enter the fuel tank.
IMPORTANT! Do not use fuel from fuel pumps labeled E85.
Use of fuel labeled E15 is prohibited by U.S EPA Regulations.
Fuel containing Ethanol can result in problems in the fuel system and engine, resulting in:
• Starting and operating difficulties.
• Deterioration of rubber or plastic parts.
• Corrosion of metal parts.
• Damage to internal engine parts.
Before Use
Tube pressure will fluctuate with temperature. Inflate tubes in sequence to 250mB/3.6psi.
Failure to observe this will compromise the sea-keeping ability and watertight integrity of the
boat. Inflation valves are fitted with quarter-turn locks to enable rapid deflation.
CAUTION. Tubes must be inflated in the correct sequence to prevent
over-inflation.
• Set valves to shut and inflate tubes evenly, starting at rear/right, rear/left, then forward
valves.
• Check bilge for fuel or water contamination.
• Tighten footwell drain plugs.
• Ensure towing valve is set in open position.
• Check engine cover latches are secure.
