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.

Fuel ﬁlter

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.

Checking the Tyre Pressures

The tyre pressure must be 100 kPa / 1.0 bar / 14.5 PSI for the front and rear wheels.

The air pressure in cutting unit's pivot wheels should
be 150 kPa / 1.5 bar / 21.8 PSI.	Tyre pressures
