OPERATING THE MOWER

Fuel Type

Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline. Purchase fuel in quantities
that can be used in 30 days.
• A minimum of 87 octane/87 AKI (91 RON). High altitude
use, see below.
• Petrol with up to 10% ethanol is acceptable.
CAUTION: Do not use unapproved fuels, such as E15 and
E85. Do not mix oil in fuel or modify the engine to run on
alternate fuels. Use of unapproved fuels will damage the
engine components and void the engine warranty.
To protect the fuel system from gum formation, mix a fuel
stabiliser into the fuel. All fuel is not the same. If starting or
performance problems occur, change fuel providers or change
brands. The engine is certifi ed to operate on petrol.
At altitudes over 5,000 feet (1524 meters), a minimum 85
octane/85 AKI (89 RON) petrol is acceptable.
For carbureted engines, high altitude adjustment is required to
maintain performance.
Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. Contact a Briggs & Stratton Authorised Service
Dealer for high altitude adjustment information. Operation of
the engine at altitudes below 2,500 feet (762 meters) with the
Fig. 6 Fig. 7
high altitude adjustment is not recommended.
Fill to base of neck to allow for fuel expansion. Do not overfi ll
the fuel tank.
(Refer fi g.6)

Controls

WARNING: Improper maintenance, use of non conforming
replacement components, or the removal or modifi cation of
the control cable(s) may cause serious injury or death.
Operate all control levers several times and ensure that the cables
move freely. Check that the engine stop lever returns freely to its
rest position when released.
(Refer fi g.7)

Before Mowing

To prevent accidents, thoroughly inspect the area and
remove all objects which when contacted by the mower
cutterblade could become dangerous projectiles. Inspect the
area for hidden obstructions which when contacted by the
cutterblade could risk health and safety or result in damage
to the mower. Remember the location of these obstructions
and ensure that you mow around them.

Starting

Stand behind the mower and hold the handle together with the
engine stop lever with your left hand. With your right hand hold
the engine start cord and pull slowly until resistance is felt,
release, then pull rapidly to crank the engine. Carefully return
the start cord to the storage position when the engine starts.
(Refer fi g.9)
If the engine does not start after 5 attempts - Refer to Trouble
Shooting.
The engine stop lever must be held firmly against the handle
to start and keep the engine running. If the engine stop lever is
released the engine will stop.
To prevent damage never pull the engine start grip when the
engine is running.
