Operating; Fuel; Starting And Stopping - Husqvarna LB448S Operator's Manual

Fuel

WARNING! Always ensure there is
!
adequate ventilation when handling fuel.
Petrol
• Use good quality unleaded or leaded petrol.
• Use fuel with a low octane grade.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Engine oil
Check the oil level before starting the lawn mower. A too
low oil level can cause serious damage to the engine.
• For the best result and function use HUSQVARNA
four-stroke oil.
• If HUSQVARNA four-stroke oil is not available, you
may use another four-stroke oil of good quality.
Contact your dealer when selecting oil. In general
SAE 30 is recommended.
• Never use oil intended for two-stroke engines.
Check the oil level before starting the lawn mower. A too
low oil level can cause serious damage to the engine.
Oil level
The lawn mower should stand on flat ground when you
check the oil level. Ensure the ignition lead has been
removed from the spark plug before you open the oil filler
cap.
Unscrew the oil cap, clean the dipstick located on the cap
and insert the cap again without screwing it down. Check
the oil level on the dipstick. If the oil level is low, fill using
engine oil up to the upper level on the dipstick.
Only use recommended engine oil. See the Technical
data section.
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 and source before starting.
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.
Always move the machine about 3 metres from the
refuelling position before starting.
