Keeping Engine Clean

Remove all grass and debris from the engine including the
exhaust / exhaust guard, the air ways in the top cowl and the
surrounding deck areas on a daily basis after use. Never spray
the engine with water during cleaning. Water can contaminate
the fuel. Always clean with a brush or compressed air.
(Refer fig.25)
Grass and debris may clog the engine's air cooling system
especially after prolonged operation while cutting tall, dry grass.
The internal cooling fins and surfaces may require cleaning to
prevent overheating and engine damage. We recommended that
this service be carried out by an authorised Briggs and Stratton
dealer.

Grassbag

Remove grass debris from the grassbag immediately after use
and check its condition for signs of damage.
To prevent accidents replace a damaged grassbag
immediately.

Deck Housing

Remove grass debris from the top and underside of the deck
housing immediately after use.
(Refer fig.27)
Fertilisers and top dressings are particularly corrosive.
Thoroughly clean the mower deck immediately after use on
treated grass and store well away from corrosive materials.
Securing Nuts & Bolts
Regularly check that all securing nuts and bolts are tight. Replace
missing or damaged items immediately.

Lubrication

Lubricate the wheels, pivot points and linkages with engine oil
every 25 operating hours.
Apply a good quality medium grease to the inner control cables,
at the point of entry and exit from their outer casting.
