General Maintenance (cont’d) SECTION 3 SERVICE 1 – HYDRAULIC OIL TANK FILLER CAP Complete change lt. 18.0 Use 46 Weight Hydraulic Oil. Replace the oil after the first 200 HOURS of operation and every 1000 HOURS thereafter or once a year. To fill or top up, check that the oil is between the min.
General Maintenance (cont’d) SECTION 3 SERVICE 3 – TRACK TENSIONING DEVICE This device is used to restore correct track tightness if they loosen during use. TIGHTENING THE TRACKS With use, the tracks tend to loosen. When operating with loose tracks, they tend to slip over the driving wheel teeth causing it to jump its housing or to work in precarious fashion, damaging and causing wear to the housing.
General Maintenance (cont’d) SECTION 3 SERVICE REPLACING THE HYDRAULIC OIL INTAKE FILTER The filter is located inside the hydraulic oil tank (see picture). Replace the filter after the first 50 HOURS of operation and every 500 HOURS thereafter. Remove the oil tank cover by loosing the screws “A”, unscrew the filter “F”...
General Maintenance (cont’d) SECTION 3 SERVICE REPLACING THE AIR FILTER The air filter “F” is located under the engine bonnet. To clean the cartridge, it is sufficient to remove the top cover, remove the cartridge and clean with com- pressed air. Do not use solvents, brushes or rags to prevent damage to the cartridge. The air filter should be replaced with another one having the same characteristics.
General Maintenance (cont’d) SECTION 3 SERVICE WHEEL GEARS Each track is driven by a reducer, coupled to a hydrostatic motor, fitted with an internal brake with negative-type of multiple discs. The brake is activated by the hydrostatic system by means of the trans- mission levers (forward - reverse).

General Maintenance (cont’d) SECTION 3 SERVICE CAP POSITION FOR FILLING CAP POSITION FOR VERIFICATION LEVEL CAP POSITION FOR VERIFICATION LEVEL CAP POSITION FOR EMPTYING Therefore, this section does not require particular maintenance. If the oil level in the reducer should decrease or increase when there are no external leaks, the internal seals of the reducer itself must be checked by an authorized service center.
General Maintenance (cont’d) SECTION 3 SERVICE PUMPS MAINTENANCE In order to service the pump and the hydraulic valve once the body is tipped and safely blocked, loose the screw “U” and “V” and then remove the protection carters After finished the necessary maintenance, locate again the panels and tie the screws. ADJUSTMENT AND ZERO SETTING OF THE HYDRAULIC PUMPS The track control levers on the control panel automatically return to zero (neutral position), inde- pendently of the revolutions of the engine.
Page 47

General Maintenance (cont’d) SECTION 3 SERVICE Keep the cable terminals fastened well and protected with grease or even better with pure Vaseline. When disconnecting the battery, the earth wire (-) must be disconnected first. When connecting the battery, the positive wire (+) must be connected first. Keep metal tools and objects away from the battery poles as these may short-circuit the terminals and pose a risk of burns.
