Maintenance Instructions
4.12.3.2 Height Limiter Adjustment Method and Requirements
Shown above, you can control the height adjustment by adjusting the limit push board on the right side of
lift shaft. Remove the nuts (1 and 2). The more the limit push board is adjusted counter-clockwise the
higher the adjustment. Adjusting clockwise will lower it.
Farm implements must be raised up when turning while doing field operations. It is required that the farm
implement has a ground clearance of 150–250 mm. after lifting. This can be achieve through setting the
length of the limit push board.
When making adjustments for long distance operations or road transportation：adjusts the position of the
limit push board; the farm implement’s lift height must have over 250 mm of ground clearance.
Tighten the fixture parts after adjustment.
IMPORTANT ISSUES: When adjusting the distance between the position clamp ring block and the
position valve, the adjustment of both the oil cylinders should be maintained in conformity with a tolerance of
0–0.5 mm. This will prevent damage on the farm implement parts.
4.12.3.3 Hydraulic Suspension System Oil Use and Maintenance
The lifter cover is on the oil tank of the hydraulic suspension
system. International standard hydraulic oil should be used
according to the environment.
Check every 50 hours to see if the oil level in the lifter cover is
within the oil level stick range.
Clean up the breather regularly. To do this, open it, take out
the filter, clean it with solvent and blow it clean with compressed
air. Replace it with a new filter elements when it Fig. 4-24
becomes difficult to clean or it is broken. Hydraulic Suspension System
