with gentle acceleration to let the oil drain plug on the front axle move into the horizontal
position, and then shut the engine. Put the transmission lever in the neutral position. Pull the
parking brake lever.
z Add new gear oil from the oil drain port on the two wheels on the end sides of the front axle and
the oil inlet port at the middle of the axle shell. And then check the oil level again.
z Tighten the oil drain plugs on the two wheels on the end sides of the front axle and the oil inlet
plug at the middle of the axle shell.
z Replace the rear axle gear oil according to the procedures above.
3.6.5 Adding Oil to Hydraulic Oil Box
Oil Level Check
①
z Park the machine on level ground and lower the bucket to the ground. Check whether there is an
angle between front and rear frame.
z Check the oil level indicator of the hydraulic oil box on the left side of the machine. The oil level
is normal if the level indicator scale is at a range of ±2 from the middle level. If the oil level
