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.
