Husqvarna K750 manual Fueling, Disconnection function for OilGuard

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 complete deactivation and 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.

Fueling

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.

•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.
