WARNING
After fuelling, never tilt the product more than 25 degrees
for this could result in fuel leakage and risk of fi re.
NOTE: Always use unleaded petrol with an octane rating
of 91 or higher.
1. Clean surface around
contamination.
2. Loosen fuel cap slowly to release pressure and to
keep petrol from escaping around the cap. Rest the
cap on a clean surface.
3. Carefully pour petrol into the tank. Avoid spillage.
4. Clean and inspect the gasket, then replace all fuel and
container caps securely.
5. Wipe up any petrol spillage. Move 9 m away from
refuelling site before starting engine.
NOTE: It is normal for smoke to be emitted from a new
engine during fi rst use.
ADDING/CHECKING ENGINE OIL
See fi gure 5.
Engine oil has a major infl uence on engine performance
and service life. For general, all-temperature use, SAE
10W-30 is recommended.
NOTE: Non-detergent or 2-cycle engine oils will damage
the engine and should not be used.
To add the engine oil
1. Be sure the product is on a level surface and the area
around the oil cap/dipstick is clean.
2. Remove the cap and seal from the oil bottle.
3. Unscrew and remove the oil cap/dipstick.
4. Slowly add oil. Fill to the "Full" line on the dipstick. Do
not overfi ll.
NOTE: Checking the oil level is done with the dipstick
seated but not screwed in.
5. Reinstall the oil cap/dipstick and secure it in place.
To check the engine oil
1. Be sure the product is on a level surface and the area
around oil cap/dipstick is clean.
2. Remove the oil cap/dipstick. Wipe clean and reseat
the oil fi ll hole but do not screw in.
3. Remove the oil cap/dipstick again and check oil level.
Add oil as needed.

WARNING
Never start or run the engine inside a closed or poorly
ventilated area; breathing exhaust fumes can kill.
Pre-checks
1. Check that the oil level is suffi cient by dipping the
dipstick.
2. Check the petrol tank has suffi cient regular unleaded
fuel.
3. Turn the fuel tap to the OPEN (ON
fi gure 22).
Starting a cold engine
1. Set the throttle lever to "Max" (down against the
handle).
2. Firmly push and slowly release the primer bulb 3 times.
NOTE: When pushing and releasing the primer bulb,
ensure that your fi nger covers and seals the centre
hole (in the bulb), and that you release the bulb at
a slow pace. This creates a partial vacuum, drawing
petrol into the primer from the carburettor. Pushing the
primer bulb forces fuel into the inlet manifold to enrich
the mixture.
3. Pull the starter grip up to 2 times.
NOTE: If the engine does not start after 2 pulls, repeat
the process of priming the fuel bulb 3 more times and
then pull the starter grip up to 2 times. Once the engine
starts, release the starter grip slowly so the rope does
not snap back.
4. Ensure that the throttle lever is set to "Max" (down
against the handle), and then proceed with mowing.
Starting a warm engine
During warm or hot starts (engine has been running in the
last 10 minutes), the engine may not restart readily. This
is due to the decompression valve in the engine which
reduces the pull force required to start the engine.Priming
the bulb is required.
1. Set the throttle lever to "Max" (down against the
handle).
2. Firmly push and slowly release the primer bulb 2 times.
3. Pull the starter grip up to 2 times.
NOTE: If the engine does not start after 2 pulls, prime
the fuel bulb 3 more times and then pull the starter grip
again. Once the engine starts, release the starter grip
slowly so the rope does not snap back.
4. Ensure that the throttle lever is set to "Max" (down
against the handle), and then proceed with mowing.
Stopping the engine
■ Return the throttle lever to the stop position (hard up
against the top of the mower handles).
