The gear pump is installed on the engine. The oil tube of front loader shall be reliably connected with
the joint 25 of oil pressure outlet tube at first when the front loader is working, then put the lift arm at
the lowest position to exhaust remaining oil in the lift cylinder. Then turn on the adjusting rod of cut-off
valve clockwise to shutoff the oil supply into the oil cylinder. Either the draft control or the position
control handle adjusted to the “lifting” position. The front loader can be operated now. When the rear
hydraulic output is used, turn out two plugs 1, exchange the joint 25, it shall be turned in and reliably
connected. Turning the hand wheel clockwise will slow down the lowering speed. As the hand wheel
is turned to the end, the pressure oil in the cylinder will completely sealed to lock the hydraulic system.
Hydraulic locking is necessary when a tractor attached with implement travels from one spot to another.
5.8 Adjustment of the Tread
(1) The distance between the front wheels can be adjusted to have 4 different lengths by means of the
telescopic tubes within the range of 1100~1400 mm.
(2) For the driving wheels, the tread may be changed by the wheel spokes and the wheel rims.
This makes it possible to have 5 different lengths of the tread within the range of 1000~1400 mm.
