Check the tires with a pressure gauge.
Minimum tyre pressure = 110 kPa (1,1 kp/cm
2
) (16 psi).
Maximum tyre pressure = 150 kPa (1,5 kp/cm
2
) (22 psi).
Tyre pressure CA 251A: 110 kPa (1,1 kp/cm
2
) (16 psi).
Check both tyres.
When changing tires it is essential that both
tires have the same rolling radius
(max. difference about 15 mm or 0.6").
No-spin equipment may otherwise be
damaged.
Change or clean the Primary filter of the air
cleaner when the warning lamp on the instru-
ment panel lights at full revs of the diesel
engine.
1. Loosen the clamp (4) and remove the dust trap (3).
2. Screw off the wing-nut at the center of the filter and
take off the inner cover (5). Clean inside the dust
trap with a clean rag.
3. Screw off the wing-nut and pull out the Primary filter
(6).
4. Wipe the inside of the filter housing (1) and intake
pipes with a clean rag.
5. Check that hoses and connections between the filter
housing and engine are intact and tight.
6. Clean the emptying slits (7) of the dust trap.
Replace the Secondary filter (2) with a new one
every third time the Primary filter is changed or
cleaned. The Secondary filter cannot be
cleaned and reused.
Use compressed air at a maximum pressure of 0.7
MPa (7 kp/cm
2
) (100 psi)
Blow up and down along the paper pleats on the inside
of the filter element. Hold the nozzle at least 10 mm
(0.4") from the pleats to avoid tearing the paper.
Change the Primary filter after cleaning it five
times.
Wear protective goggles when working
with compressed air.
