Safety Check - Williams DIESELJET 445 Manuel Du Propriétaire

General
CAUTION. Operate the boat with due care and at a speed appropriate to the sea
conditions. Be aware of local laws and restrictions. Always carry out a visual check of
the boat and its components prior to use. Adhere to the maintenance/service schedule.
New Engine Break-in Period
The way your engine is operated during the first 50 hours of use will play a very significant role
in determining its ultimate performance and lifespan. The engine must be operated at suitable
speeds and power settings during the break-in period. Refer to Yanmar engine manuals for
information on running the engine during the first 50 hours of operation.
Fuelling
As part of its pre-delivery inspection your new Dieseljet has been fully tested and
drained of fuel. When refuelling use only Diesel fuel.
• Do not refuel with engine running.
• Remove Forward seat cushion to expose fuel filler cap (445 only).
• 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 directly hose around the fuel filler area as
water may enter the fuel tank.
Note: Boats fitted with the Yanmar 4JH4 engine are fitted with a fuel primer/pump.
This may require pumping at first use or when left for extended periods.
Before Use
Tube pressure will fluctuate with temperature. Inflate tubes in sequence to 250mB/3.6psi, starting
at the rear valves. Failure to observe this will compromise the sea-keeping ability and water tight
integrity of the boat. Inflation valves are fitted with quarter-turn locks to enable rapid deflation.
• Close inflation valves; inflate tubes evenly, starting at rear/right, rear/left, then forward valves.
• Check bilge for fuel or water contamination.
• Check engine cover latches are secure.
• Check seacock is open before use.
Fire Extinguisher
Inspect system pressure regularly; refer to the extinguisher label for Pressure/Temperature
Table. In some conditions the extinguisher may require resetting; this is done by pressing
the extinguisher reset button found on the extinguisher display unit, refer to Boat System
Arrangement for its location.

Safety Check!

WARNING. ALWAYS attach yourself to the safety lanyard when engine is running. Before
setting off as a precautionary measure always test lanyard for its functionality by pulling
away from its seating – engine should always stop.
WARNING. NEVER operate the boat when bathers are using the boarding ladder, risk of
serious injury exists from reverse deflector.
WARNING. NEVER investigate engine bay with engine running or ignition on.
Starting Your Dieseljet
• NEVER run engine if ambient temperature is excessively high or below -16°C (-5°F).
• NEVER attempt to switch off engine using battery isolator.
Ensure boat is in a depth of at least 0.95m/3ft of water before attempting to start engine.
•
• Ensure all passengers are correctly seated.
1 Turn on battery isolator.
2 Run bilge blower for 4 minutes.
3 Secure any loose ropes that could get sucked into jet unit.
4 Ensure shift lever is in neutral position.
5 Connect safety lanyard to switch.
WARNING. Personal injury may result if not attached.
6 Test safety lanyard for correct functionality (see Safety Check! above).
Warning Lamps/Alarms
CAUTION. Risk of engine damage. In the event that a warning lamp or buzzer activates
during use, STOP engine immediately, investigate cause and refer to engine manual.
Contact your authorized Williams Dealer.
After Use
To prolong life it is very important to wash entire boat with fresh water after use and prior
to storage, especially the jet pump area. Failure to carry out fresh water washing will
significantly reduce the life of underwater components. Check anodes routinely.
• Flush engine (refer to Flushing Procedure on page 14)
• Wash jet pump
• Check bilge of boat and dry any residual water
• Rinse footwells and upholstery with fresh water
• Isolate battery
