HYDRAULIC OIL

Unlatch and swing open the Oil Reservoir / Fuel tank Cover (20). Remove the reservoir cap to check the oil level. The hydraulic oil level should be half way up the screen filter inside the filler neck of the reservoir. Add SAE 10W30 motor oil if it is below this level. Change the oil if major contamination from a mechanical failure occurs.

ENGINE OIL – GASOLINE (PETROL) & LPG

Check the engine oil level when the machine is parked on a level surface and the engine is cool. Change the engine oil after the first 35 hours of operation and every 150 hours after that. Use any SF or SG rated oil meeting API specifications and suited to seasonal temperatures. Refer to the Engine System section for oil capacities and additional engine specifications. Replace the oil filter with every oil change.

ENGINE OIL - DIESEL

Check the engine oil level when the machine is parked on a level surface and the engine is cool. Change the engine oil after the first 35 hours of operation and every 150 hours after that. Use CF, CF-4 or CG-4 oil meeting API specifications and suited temperatures (*important reference the oil/fuel type note below for further diesel oil recommendations). Refer to the Engine System section for oil capacities and additional engine specifications. Replace the oil filter with every oil change.

* Diesel Lubricating Oil Note:

With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a low-sulfur fuel on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable to employ the CF, CD or CE lubricating oil with a high total base number. If the CF-4 or CG-4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals.

• Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.

ENGINE COOLANT

Open the Engine Compartment Cover (1) and observe the coolant level in the Coolant Recovery Tank (22). If the level is low, add a mixture of half water and half automotive type anti-freeze.

CAUTION!

Do not remove the Radiator Cap (23) when the engine is hot.

ENGINE AIR FILTER

Check the Engine Air Filter Service Indicator (24) before each use of the machine. Do not service the air filter unless the red flag is visible in the service indicator. NOTE: After cleaning or replacing the engine air filter, the service indicator can be reset by pressing the end of the indicator.

CAUTION!

When servicing the engine air filter elements, use extreme care to prevent loose dust from entering the engine. Dust can severely damage the engine.

The engine air filter contains a Primary (outer) and a Safety (inner) filter element. The Primary Element may be cleaned twice before being replaced. The Safety Element should be replaced every third time that the Primary Filter Element is replaced. Never attempt to clean the Inner Safety Element.

To clean the Primary Filter Element, unsnap the 2 clips at the end of the air filter and remove the end housing. Pull the primary element out. Clean the element with compressed air (maximum pressure 100 psi) or wash it with water (maximum pressure 40 psi). DO NOT put the element back into the canister until it is completely dry.
