Pressure air can cause personal injury. When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes. The maximum air pressure must be below 205 kPa (30 psi) for cleaning purposes. |
 |
Remove the primary filter element for cleaning, only if the indicator is showing red. The primary filter element should be replaced after the sixth cleaning, or every year. The secondary element should not be cleaned and should be replaced after the third cleaning of the primary filter element.
Removal of the Air Cleaner Elements
Loosen wing bolt (1, Fig. 668) and remove cover (2, Fig. 668). Take the rubber ring out of the cover, shake out the dust and clean thoroughly.
Unscrew wing bolt (1, Fig. 669) from the primary filter element and remove filter element (1, Fig. 670).
Loosen wing bolt (2, Fig. 670) from secondary filter element and remove element (3, Fig. 670).
Cleaning
Blow air through the primary filter element from inside to outside and turn and move up and down the air jet at the same time. Avoid any damage.
| NOTICE |
|---|
Never clean the filter element by tapping. |
Washing
Fouling by soot or oil requires the element to be washed. Soak the primary filter element for approximately 15 minutes in warm water containing the solvent specified by the filter manufacturer, then move the element back and forth or up and down in the solvent. Rinse the element carefully with clean water from inside to outside. Install primary filter element only when dry.
Inspect
Check the filter element for damage. Be sure all seals and their seats are in perfect condition. Check filter element by inserting a light bulb.
Use undamaged filter elements only. For reassembly the sequence should be reversed.
Swing Drive
Check the Oil Level
|
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. |
|
Place machine on level ground.
Unscrew level plug (2, Fig. 696). The oil level must be up to the lower edge of the hole. If required, remove breather filter (1, Fig. 696) and add oil if necessary.
Steering Axle
Check the Oil Level
|
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. |
|
Place machine on level ground.
Unscrew the oil fill plug (2, Fig. 692). The oil level must be up to the lower edge of the hole. If necessary, add oil.
Steering Axle Hub Unit
Check the Oil Level
Place the machine on level ground so that the drain plug (3, Fig. 691) of the hub unit is at the lowest point and the line is horizontal.
Unscrew the oil fill plug (1, Fig. 691). The oil level must be up to the lower edge of the hole. If necessary, add oil. Install plug. Repeat procedure on the three remaining hub units.
Axle with Gearbox
Check Oil Level
|
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. |
|
Place the machine on level ground.
Gearbox with Differential Unit
Remove the oil fill plug (1, Fig. 692). The oil level must be up to the lower edgeof the fill hole. If necessary, add oil.
Gearbox Primary Housing
Remove oil fill plug (1, Fig. 784). The oil level should be up to the lower edge of the fill hole. If necessary, add oil.

Parking Brake
Adjust
With new brake or new shoes, adjust brake so that the stroke of the actuator in the brake (spring) accumulator is 7 to 10 mm (.28 to .40 inch) from released to applied position.
Check Thickness of Brake Lining
The wear limit of the lining is 2 mm (.08 inch). This is reached when the stroke of the accumulator is 68 mm (2.68 inch) from released to applied position (Fig. 690).
NOTE: With parking brake applied the hydraulic drive motor can not be activated because of a safety device.
Service Brake
Check Thickness of Brake Lining
The wear limit is 3 mm (.12 inch). If thickness is 3 mm (.12 inch) or less, change the brake linings. Consult your AVSpare dealer for service.
Antifreeze Pump
Filling
The antifreeze pump allows injection of antifreeze and prevents icing in air tanks, lines and valves. The pump is visible after opening the rear left door.
For topping up antifreeze and checking the available contents (as well as for frost-free months) the pin with the T-handle (1, Fig. 592) should be pressed into the housing against the lower stop and locked by turning through 90°. The fill plug (2, Fig. 592) with dipstick can then be removed and methylated spirit (ethyl alcohol) poured in as antifreeze.
If the fill plug (2, Fig. 592) is removed, air may be heard to escape through a pressure compensation hole. Filling should be done by way of a funnel, which is raised enough for the air to escape from the container. Close the filler neck and place pin with T-handle in antifreeze position.
Antifreeze Position (During Winter Below +5°C)
Pull up T-handle (1, Fig. 592).
Summer and Refilling Position
Press T-handle downward against stop and turn through 90°.
Tire Inflator
Check the Tire Pressure
Emergency Use Only
The tire inflator on the pressure governor is located in the upper carriage at the rear left-hand side, next to the antifreeze pump, and is accessible after opening the rear left door.
Remove dust cap (3, Fig. 592) and screw on tire inflation hose. Connecting the tire inflation hose automatically opens the valve for the tire inflator.
Before inflating tires, operate one of the drain valves (Fig. 581), in order to decrease the tank pressure below the response pressure of the governor 6.6 bar (647 kPa or 94 psi), as no air is delivered during idle running.
See "Tire Inflation" in the "Safety" section.
