THROTTLE
BEFORE STARTING ENGINE ADD OIL & PETROL
Check the engine manufacturers Instruction Manual, to ensure you do not invalidate the engine warranty,
before undertaking any actions.
YOUR LAWNMOWER IS SHIPPED WITHOUT OIL OR PETROL IN THE ENGINE.
Before each subsequent use, the oil level must be checked and if necessary topped up with SAE30 engine
oil. It is recommended that oil is poured into the engine, using a funnel.
OIL FILLER CAP/DIPSTICK
CAUTION: DO NOT overfill the engine with oil (from empty, (470ml of oil will fill the oil to the Upper Limit on
the dipstick, or it will smoke heavily from the exhaust on startup.
1. Be sure that the lawnmower is on level ground.
2. Remove the oil dipstick from the oil fill spout.
3. Insert and tighten the dipstick.
IMPORTANT:
Check the oil level before each use. Add oil if needed. Fill to the full line on the dipstick.
Change the oil after every 25 hours of operation or each season. You may need to change the oil more
often under dusty, dirty conditions. See “TO CHANGE ENGINE OIL” in the Maintenance section of this
manual.
ADD PETROL
Fill the fuel tank to the bottom of the tank filler neck. Do not overfill. Use fresh, clean, regular unleaded
petrol. Do not mix oil with petrol. Purchase fuel in quantities that can be used within 30 days to ensure
fuel freshness. Old or stale fuel can cause damage to the engine carburetor, which would not be
covered under the warranty.
CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use petrol near an open flame.
CAUTION: To avoid engine problems, the fuel system should be emptied before being stored for 30 days or
more. To empty the fuel tank, start the engine and let it run until the fuel lines and carburetor are empty. Use
fresh fuel for your next use of the machine. See Storage Instructions for additional information.
