drive pulleys (see Section 2) or the clutch

cable has broken or become detached (see a

service dealer).

FOR MOWERS WITH THE CLUTCH BAR RUNNING

ACROSS THE HANDLE:

a) Check the clutch cable runs up the left hand

side of the main handle through the anchoring

bracket on the handle. If the cable is not in

this bracket, insert it and secure the bracket to

the handle, then follow the instructions in b)

below to adjust the tension.

b) The cable may have stretched a little with use.

Slacken the bottom nut on the adjusting

barrel and then tighten the top nut on the

adjusting barrel to take up un-required

slack in the cable. NOTE: The cable

should have about ½” of play on it.

c) If the above steps do not return the

tension to the cable and restore the drive,

the cause of the problem may be the belt

has come off the drive pulleys (see

Section B) or the clutch cable has broken

or become detached (see a service

dealer).

B REPLACING THE BELT

To replace the belt on these machines, it will

involve tipping the machine to gain access to the

belt. You will need to observe certain general and

safety precautions prior to undertaking this task.

Chose an appropriate firm surface to work on such

as a workbench - not standing on a high quality

patio or lawn (these could be stained or damaged

by machine fluids).

WARNING: Make sure you have disconnected the

HT lead from the spark plug (it is a simple push fit)

before you undertake ANY of the work below.
