If belt replacement is necessary, remove the
main access panel as detailed above. Then
remove the Locating Spigot Bar from the
fan/pulley assembly, Fig. 14 and separate the
fan/pulley assembly, Fig. 14 and the coupling,
Fig. 15. The Belt ‘0’ can be replaced easily.
Lay the belt into its pulley and inside the idler but
do not fit to the engine pulley. Refit the
Fan/Pulley assembly and Locating Spigot Bar
allowing the rubber coupling to align with the
coupler halves.
Once the four Spigot Bar retaining bolts have
been replaced and tightened, the belt ‘
O ’ can be
refitted to the engine pulley as follows: -
a) Disconnect the plug lead.
b) Fit the belt partially into the pulley
groove.
c) Turn the engine slowly using the recoil
starter.
Take extreme care not to trap fingers or
clothing.
DO NOT USE THE ELECTRIC STARTER
Check that the belt is installed correctly and that
it is not rubbing anywhere.
CYLINDER DRIVE BELT ADJUSTMENT
Screw the Cylinder Drive Belt Adjuster ‘ P ’ Fig.
16 away from the body of the machine to
increase tension on the cylinder drive belt and
towards the machine to slacken the belt tension.
The tension should be set to a deflection of
20mm as shown in Fig. 16.
CYLINDER CLUTCH DRIVE BELT
Having removed the main access panel, remove
the Main Drive Belt ‘
O ’, Figs. 14 and 15, by
loosening and removing the Locating spigot Bar,
Fig. 14 and separating the coupling Fig. 15.
Then undo the three screws, Fig. 17 which
secure the top of the cutter ‘T’ drive pulley and
remove the top pulley half.
The belt ‘0’, Figs. 15 and 17, can now be
removed freely and replaced.
To replace, reverse the above procedure.
CYLINDER CLUTCH ADJUSTMENT
The clutch is designed to be partially self-
adjusting, however periodic inspection should be
carried out to ensure that optimum performance
is being attained.
Should adjustment be necessary, tighten or
loosen the screw on the clutch link rod, Fig.
18. Moving the nut rearward tensions the
cylinder belt.
HEIGHT OF CUT
The cutting height of each cylinder unit is
determined by the position of the rear rollers.
Adjustments can be varied from ½in to 2½in
(12mm to 64mm).
To Adjust
1. Park the machine on flat, level ground. Stop
the engine, engage the Parking Brake ‘ H ’ and
disengage the Cylinder Drive (Lever) ‘G’.
2. Adjustment is made by turning the Roller
Adjustment Bolts ‘ R ’, Fig. 12. Clockwise
lowers the cylinder, anti-clockwise raises the
cylinder. Set the roller to the required height
and tighten the Roller Adjuster Bolts. Set all
three units to the same height. A series of
notches are etched in the side plate to assist
in achieving a uniform setting, see Fig. 19.
3. A practical tip when positioning the roller.
Remember the blade cutting edge is ½in
(12mm) up from the underside of the bottom
blade.
CUTTING CYLINDER TO BOTTOM BLADE
A A
Please note that cylinders are sharp and care
taken at all times.
To check that a cutting cylinder is set correctly in
relation to the bottom blade, proceed as
follows: -
Stop the engine , slacken the Cylinder Drive Belt
Adjusters ‘ P ’, Fig. 16, hold a thin piece of paper
between the edge of the bottom blade and a
spiral cutter and rotate the cylinder manually. If
correctly set, the paper should cut cleanly along
the length of the bottom blade.
If it does not then adjustment may be
