add coolant if needed.
Frost precautions (Cold climate).
Antifreeze solutions must be added to
the cooling system water. Use Universal
Antifreeze, available from ITMCO Dealer,
who will advise you of the correct propor-
tions of antifreeze mixture to suit your
climatic conditions. The dry ice point in
the following table (See table 4-3) can be
regarded as the safe limit temperature for
a given concentration of antifreeze/water
solution. See ‹Capacities› page 5-08 for
the capacity of your cooling system.

It should be remembered that an
antifreeze solution not only prevents
freezing, it also contains an anticorrosion
additive that protects the cooling system.
The mixing of different antifreezes can
lead to the loss of corrosion protection and
is therefore not recommended.
Caution
If an antifreeze solution is not used
during frosty weather, the coolant must
be drained after work to prevent damage
from freezing. Use the procedure under
draining the cooling system.
Clutch
Note
When the tractor enters service, or
has new clutch linings fitted the clutch
must be carefully bedded in (See op-
eration section page 3-03). The clutch
pedal linkage must be checked frequently
during the first 50 hours and necessary
adjustments made immediately. Subse-
quent checks must be made at 100 hour
intervals.
Main clutch adjustment (Fig. 35)
Check the clutch adjustment every
100 hours.
Fig. 35:
1. Measure the clutch pedal free travel ‹A›,
this should be between 20 and 25 mm
(3/4 and 1 in) at the pedal pad.
2. If the pedal free travel is out of adjust-
ment turn the adjuster nut at the end of
the clutch rod left or right to adjust ped-
