- Fill up the hydraulic oil HV68 (approximately 8,5 l )
- Start the engine and move forward and backward to get rid of air in the hydraulic system (the wheels must
move smoothly)
- Fill up the oil so that the level falls between the dipstick lines.
- Drive to warm up the oil to operating temperature and check tightness of the oil filter lid and tank cap
