(2) To operate the hydraulic lift
When a tractor operates in the field, the control of working depth is selected according to its
attachments and job requirements. There are three ways available for working depth control through
putting the control handle at different positions on the sector plate, which include position control,
draft and position combined control and float control. The upper segment on the sector plate is for
position control, the middle for combined control and the lower for draft control.
There are a hydraulic output connection and a control valve for lowering speed, located on the
cylinder head in the front end of hydraulic lift. The lowering speed control valve also 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. When the hydraulic output is
used, the lifting arm must be at its lowest position and the hydraulic system must be completely locked
to enclose oil from entering into the cylinder. To supply hydraulic output, operate the handle.
4.4 Operation of Electrical Equipment
The electrical equipment of the tractor is used to start engine, meet the needs of giving indication signals
and lighting for operation at night, etc.. Therefore it is very important to use the electrical equipment
correctly.
1. Battery
A. Preparation
(1) Clean the surface of a new battery. Screw off the plastic cover and make the air hole on the cover
open.
(2) The specific gravity of the electrolyte used in the battery is 1.26(15 ° C) in the tropics, 1.28(15 ° C) in
temperate zone and 1.29(15 ° C) in frigid zone. Fill the battery with the electrolyte when it cooled to
25~30 ° C. After a standstill of 20 minutes, the battery can be used.
(3) The electrolyte level should be 10~15mm above the protecting plate.
(4) If the battery is stored over a year, it should be changed with electric current of 11.5A for 5 hours.
