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 g.30)
Grass and debris may clog the engine's air cooling
system especially after prolonged operation while cutting
tall, dry grass. The internal cooling ns and surfaces
may require cleaning to prevent overheating and engine
damage. We recommended 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 g.31)
Deck Housing
Tip the mower over onto its left hand side thus ensuring
that the air cleaner is kept uppermost to prevent
engine damage - Code 493. For Code 563, please tip
your mower onto its right hand side. Remove grass
debris from the top and underside of the deck housing
immediately after use. (Refer g.32)

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:
1. Stop the engine.
2. 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.
3. 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. (Refer g.33 & 34)
4. 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
