MAINTENANCE

Clutch Cable Adjustment

At any time the operator feels that the mower is
loosing drive, check the following.
• Stop the engine.
• Pull the mower backwards at the same time
progressively engage the clutch lever until the rear
rollers lock, at this point the clutch lever should be
60 mm from the handle.
• If the distance between the clutch lever and handle
is less than 60 mm regulate the engagement
position using the black plastic cable adjuster (1) to
regain the 60 mm distance.
Note this adjustment is approximate, at the nearest
opportunity, a service should be carried out to ensure
the spring on the clutch cable attached to gearbox is
correctly set. This adjustment should be done using
the black plastic cable adjuster (1).
(Refer fi g.31)
With the clutch lever fully engaged, the cable should
be adjusted to give a spring extension of 10 mm.

Securing Nuts & Bolts
Regularly check that all securing nuts and bolts are
tight. Replace missing or damaged items immediately.
Rear Defl ector
WARNING: Improper maintenance, use of non
conforming replacement components, or the removal
or modifi cation of the rear defl ector may cause death
or serious injury.
Remove grass debris from the rear defl ector
immediately after use and check its condition for signs
of damage.

Carburetor Adjustments

Never make adjustments to the carburetor or engine
speed. The carburetor was set at the factory to operate
effi ciently under most conditions.
Do not tamper with the governor spring, linkages, or
other parts to change the engine speed detailed in
the Product Specifi cation section. If any adjustments
are required contact your Hayter Authorised Service
Dealer for service.

Blade Brake Test

The engine and blade are designed to stop within
3 seconds, after you release the engine stop lever.
Ensure that the engine stop lever functions properly
each time before you operate the mower.
If the blade does not stop within 3 seconds or there
is a grinding or scraping, metal-to-metal noise when
you release the engine stop lever, contact a Hayter
Authorised Service Dealer.
This same recommendation applies if you observe
heavy vibrations when using the mower.

Lubrication

Lubricate the wheel bearings, pivot points and linkages
with engine oil yearly or before storing mower away.
Apply a good quality medium grease to the inner
control cables at the point of entry and exit from their
outer casing.
Do not add lubricant or grease to the polymer rear
roller bearings.
