CHANGE THE ENGINE OIL
Pour fresh oil into the engine through filler plug “5” (fig. D2/3), until the level reaches the
max. notch on level rod “6” (Fig. D2/3).
Start up the engine at minimum speed and observe the oil low pressure indicator.
Keep the engine running at minimum speed until the low pressure indicator switches off.
Switch off the engine immediately if the low pressure indicator does not switch off after
about 10 seconds and check for the cause of the oil pressure failure in the engine.
Check the oil filter seal and the discharge screw seal.
About 5 minutes after switching off the engine, check the oil level and, if necessary, top up
with oil up to the max. notch on level rod “6” (Fig. D2/3).
D3 - POLY-V RIBBED BELT
REMPLACER
Replace the ribbed V-belt if one of the following types of damage illustrated is present
(C1/3).
Take great care while disassembling and assembling the ribbed V-belt, keeping the fingers
well out of the area between the pulley and the belt.
Insert release lever “2” (fig. D3) using a 17 mm wrench on the hex head screw of the belt
tightener roller “1” (Fig. D3) .
Tip the belt-tightener roller upwards and remove the ribbed V-belt. Reposition the belt-
tightener device.
Check to make sure the belt-tightener device and the pulleys are in perfect condition
(for example, that there are no damaged bearings on the belt-tightener device, the belt-
tightener roller and the return rollers and that the pulley profile is not worn); replace the
components if necessary.
Apply the ribbed V-belt (new) on all the pulleys, except on the belt-tightener roller (observe
Fig. D3 which shows the route of the ribbed V-belt).
Rise the belt-tightener roller by means of a lever, apply the ribbed V-belt and then bring the
belt-tightener roller backwards.
Remove the release lever and check to ensure the ribbed V-belt is lodged correctly on the
pulleys.
