Fuel Saving Tips
In order to save fuel and ensure maximum oil service life, observe the following:
Air Cleaning System
1. Clean the air cleaner regularly to prevent dust build-up.
2. Every 50 hours and every day in dusty conditions.

Clean the air filter element with compressed air.

If the rubber sealing is damaged or does not function, replace it with a new one. Check for leaks
regularly.

Also check the air pipes of the filter, remove any leaks immediately.
Note: If air cleaning system is not properly maintained, it will lead to early wear of piston rings &
sleeves. This will lead to problems like loss of engine power, excessive oil consumption fuel
consumption.
Engine
1. Do not load the engine to the maximum after starting a cold engine. Observe the coolant temperature
gauge to check engine warm-up (this will extend engine service life).
2. If there is excessive black smoke from the exhaust, check the air filter element and the high pressure fuel
circuit.
3. Do not run the engine without load for more than 2 minutes. It is better to stop the engine rather than run it
idle. This will reduce fuel consumption.
Clutch & Brakes
1. Do not use clutch slip to reduce speed or overcome momentary overload. Always shift to a lower gear.
2. If the tractor is to be parked for an extended period of time, it is recommended to shift the lever into neutral
and release the clutch pedal.
3. Do not switch clutch and brake pedals.
4. When driving downhill, reduce engine throttle and use low gear. When decelerating, do not rely solely on
the braking effect of the brakes.
Oil System
1. Always use the recommended grade and type of oil.
2. Every day before starting the engine, check the oil level using the dipstick and add fuel to the required
level.
3. Regularly replace the engine oil according to the service interval. When replacing the fuel filter, replace the
filter sealing at the same time.
Lubricating oils always consist of a base oil and additives adjusting the properties of the resulting lubricant,
such as anticorrosive efficiency, acid neutralization, preventing the formation of carbon soot deposits.
Fuel System
1. Always use pure diesel only.
2. It is advisable to refuel the fuel tank after work to avoid water condensation in the tank.
3. If the engine power decreases, replace the filter. Do not change both filters at the same time. Failure to
follow these instructions will shorten the service life of the fuel system. Also, it will lead to excessive black
smoke and excessive diesel consumption.
Permissible Fuels
If other fuels are used which do not meet the requirements of the operating manual, the
warranty will be voided.
