MOWER MAINTENANCE

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 to fi g.28)
Grass and debris may clog the engines air cooling system
especially after prolonged operation whilst cutting tall, dry
grass. The internal colling fi ns and surfaces may require cleaning
to prevent overheating and engine damage. We recommend
that this service be carried out by an authorised Hayter Service
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.
(Refer fi g.29)

Deck Housing

Remove grass debris from the top and underside of the deck
housing immediately after use.
(Refer fi g.30)
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.
Clutch Cable Adjustment
At any time the operator feels that the machine is loosing drive,
check the following.
• Stop the engine.
• Pull the machine backwards at the same time progressively
engage the clutch lever until the rear rollers lock, at this
point the clutch lever should be 60mm from the handlebar.
• If the distance between the clutch lever and handlebar is
less than 60mm regulate the engagement position with the
black plastic cable adjuster to regain the 60mm distance.

Note this is a temporary adjustment and at the nearest
opportunity a service should be carried out to ensure the
spring on the clutch cable attached to the gearbox clutch
is set correctly. This adjustment should be done using the
metal adjuster at the control with the plastic adjuster reset
fully wound in. When the spring is set tighten the inner lock
nut to secure in position.
