Bleeding The Fuel System; Servicing The Fuel Filter; Checking The Tyre Pressures - Husqvarna PT26 D Operator's Manual

Bleeding the fuel system

If you have run out of fuel, the fuel system must be
bled. Facilitatebleeding by pumping using a hand
pump. Remove the fuel tank filler cap and check the
return fuel to the tank. When bubble free fuel flows to
the tank, the engine can be started.
Carry out full bleeding as follows:
1. Slacken off the bleed screw on the fuel filter holder
at least 1/2 a turn.
2. Pump using the hand pump until clean fuel,
without air bubbles, exits the drain hole. Tighten
the screw moderately.
3. Slacken off the bleed screw on the injection pump
at least 1/2 a turn. Pump using the hand pump until
clean fuel, without air bubbles, exits the drain hole.
Tighten the screw moderately.
4. Rotate the engine with the starter motor for a
maximum of 15 seconds. Wait 30 seconds before
the next start attempt.
Servicing the fuel filter
IMPORTANT INFORMATION:
All action taken in the fuel system requires utmost
cleanliness to prevent damaging the injection pump.
Use a qualified technician. Damage caused by poor
hygiene is not covered by the warranty.
The fuel filter must be replaced regularly, for intervals
see Maintenance schedule, page 35, or if the feed
pressure, has dropped below the permitted value due
to a blocked filter. Low feed pressure can also be due
to poor fuel hygiene, e.g. defective excess flow valve.
The fuel filter should be replaced by a qualified
technician, there is a risk of damaging the injection
pump if carried out incorrectly. Contact your
Husqvarna workshop.
Used fuel filters areare environmentally hazardous
waste.
