SAFETY AND OPERATORS MANUAL
9.1 MAINTENANCE
CUTTING CYLINDER ADJUSTMENT
(Fig. 24). Before use, check the cutting cylinder
adjustment, which must be set correctly and locked.
To do this, check the adjustment by revolving the
cutting cylinder manually and testing with thin paper,
newspaper will do. If the paper is not cut cleanly,
unlock the bottom block locks (A) by turning them
clockwise. Next turn the nut (B) on top of the bracket
clockwise a little at a time until the cutting cylinder
will cut paper cleanly. The cutting cylinder MUST
spin freely. Retighten the bottom block lock securely,
adjusting nut (B) as necessary to maintain correct
setting. The correct setting of the unit is essential for
good performance and long life.
HEIGHT OF CUT ADJUSTMENT
(Fig. 25). The machine is supplied to give a medium
cut. To alter the height of cut remove the bolts (A)
which secure the rear roll carriages and move the car-
riages up or down as required. Replace and securely
tighten the bolts.
Note The nuts (B) need not be slackened to do this.
Caution A machine should never be used with the
bottom blade pressing on the ground as the cutting
cylinder may be damaged by the bottom blade being
forced upwards, also the wear is greater and the
machine will be harder to work.
TYRE PRESSURE
The tyre pressure should be maintained at 1.05 kg/
cm
2
(15 psi).
SCRAPER
Scrapers are intended for use in wet, muddy condit-
ions and should be adjusted so that they are just clear
of the rear roll. They must never be allowed to contact
the rear roll.
REMOVING THE CUTUING CYLINDER
(Fig. 30). The cutting cylinder can be removed without
dismantling the remainder of the machine. Remove
the small cover (A) and gasket from the main gear
cover. Take out the four screws securing the cylinder
housing (B) to the side frames. The cylinder can
now be lifted out by a steady upward pull applied
simultaneously to each end of the cylin der.
GENERAL MAINTENANCE
AND STORAGE
After use, it is recommended that you clean off the
machine, brush or wipe oil on to the cutters. A few
turns in reverse when you are doing this will scrape oil
on to the edge of the bottom blade.

9 MAINTENANCE
If the machine is washed down use low pressure
only, otherwise water will be forced into the bearings
and housings and cause corrosion which will shorten
the working life.
Use only genuine parts supplied from your
approved Textron Turf Care and Specialty
Products Dealer, when maintaining and
repairing your equipment.
