2 DESCRIPTION
2.1 Drive
The machine has 4-wheel drive. Power is transferred hydraulically. The engine drives an oil pump, which pumps oil through the rear and front axle drives. The front and rear axles are connected in series, forcing the front and rear wheels to rotate at the same speed. Both axles are equipped with a differential for easier turning. Front-mounted implements are powered via drive belts.
2.2 Steering
The machine is articulated, meaning the chassis is divided into front and rear sections that can turn relative to each other. This allows for a very small turning radius, enabling the machine to turn around obstacles like trees.
2.3 Safety system
The machine is equipped with an electrical safety system that interrupts certain activities to prevent dangerous or incorrect maneuvers. For example, the engine cannot be started if the clutch-parking brake pedal is depressed. The operation of the safety system must always be checked before each use.

4 STARTING AND OPERATION
⚠️ The machine must not be operated unless the engine casing is closed and locked. Risk of burns and crushing injuries.
4.1 Filling with petrol
Always use lead-free petrol. Never use 2-stroke petrol mixed with oil.
The tank holds 14 litres. The level can be read through the transparent tank.
NOTE! Ordinary lead-free petrol is perishable and should not be stored for more than 30 days. Environmental petrol (alkylate petrol) can be used as it is less harmful to people and nature.
⚠️ Petrol is highly inflammable. Always store fuel in containers made for this purpose. Only fill or top up with petrol outdoors, and never smoke while doing so. Fill up with fuel before starting the engine. Never remove the filler cap or fill with petrol while the engine is running or still warm.
Never completely fill the petrol tank. Leave an empty space (at least the entire filler tube plus 1-2 cm at the top) to allow petrol to expand without overflowing. See fig. 10.
4.2 Checking the engine oil level
On delivery, Pro 16 and Pro 20 (Briggs & Stratton) are filled with SAE 30 oil. Prestige and Pro 25 (Kohler) are filled with SAE 10W-40 oil.
Check the oil level every time before use to ensure it is correct. The machine should be standing on level ground.
Wipe clean around the oil dipstick. Unscrew and pull it up. Wipe off the dipstick. Slide it down completely and tighten it. Then unscrew it again and pull it up. Read the oil level. Top up with oil to the "FULL" mark if the level is below it. See fig. 11-13.
The oil level must never exceed the "FULL" mark, as this can cause the engine to overheat. If the oil level exceeds the "FULL" mark, drain oil until the correct level is achieved.
