FUEL HANDLING
Disconnection function for OilGuard
Machines fitted with OilGuard have a built-in system for
identifying incorrect fuel mixtures. Once the machine is
running, a detector reads the fuel quality which takes about
ten seconds. If the correct amount of Husqvarna OilGuard oil
has been used, the machine will run at a normal speed. If the
wrong type of oil has been used, the machine senses this and
restricts the speed of the engine to 3,800 rpm to avoid
damaging the engine. In order for the machine to run at
normal speed again, you must drain the incorrect fuel mixture
and then fill the machine with a fuel mixture containing the
correct ratio (2 %) of Husqvarna OilGuard oil.
When the machine is delivered, the OilGuard plug A (blue)
and the blue indicator pin B are fitted in the tank. If you are in
a situation where you do not have access to Husqvarna
OilGuard oil, but you have oil of a similar quality, you can
deactivate the OilGuard system using the disconnection
function. To deactivate the function, pry off the OilGuard plug
using a screwdriver and then break off the indicator pin. Now
fit the disconnector plug C (orange) in the tank to cover the
hole.
If you want to reactivate the OilGuard system, press the
OilGuard plug again. The system is then reactivated, but note
that the broken indicator pin cannot be refitted. A broken
indicator pin indicates that the OilGuard system has been
disconnected. You can purchase a new indicator pin as a
spare, but this is only sold in grey which indicates that the
OilGuard system has been deactivated since the machine left
the factory.
Fuelling
• Keep the handle dry and free from oil and fuel.
• Ensure that the fuel is well mixed by shaking the container
before filling the tank.
• Always exercise care when refilling the fuel. Move the
machine at least three metres from the fuelling area
before it is started. Check that the fuel cap is tightened
correctly.
• Clean around the fuel cap. Clean the fuel and oil tank
regularly. The fuel filter should be changed at least once a
year. Contamination in the tanks causes malfunction.

WARNING! Taking the following precautions,
will lessen the risk of fire:
Do not smoke or place hot objects near fuel.
Always shut off the engine before refuelling.
When refuelling, open the fuel cap slowly so
that any excess pressure is released gently.
Tighten the fuel cap carefully after refuelling.
Always move the machine away from the
refuelling area before starting.
