2.14.3 Lowering Speed Adjustment
Select a suitable lower speed for the farm implement to keep
from being damaged by heavy impact when it contacts the ground.
Before delivery, the descending speed regulating valve was
adjusted. The owner/operator can readjust the valve according to
the weight of farm machinery and ground hardness.
•
The farm machine will lower when the adjustment valve (A)
is turned in a clockwise direction.
•
When turning the regulating valve (A) counterclockwise, the
lowering speed of the farm machinery will increase. （See
figure 2-23）
2.14.4 Application of the Hydraulic Output and
Lock
•
Turn the adjustment valve (B) in a counterclockwise
direction until the valve is closed. This will also close
the adjustment valve on the inlet and outlet of the oil
cylinder. The male connector on the quick change
coupler is connected with the oil inlet of the farm
machinery. The hydraulic output female connector (A)
is connected with the male connector on the farm
machinery. Push the distributor control handle to the
lifting position to achieve the appropriate hydraulic
output. Simple hydraulic output can only control a
single-action oil tank.
•
When using the hydraulic output, the farm implement
should be in the lift position, if the lower speed
adjustment valve (B) is closed and the oil in the tank
can not return. The farm implement should be locked in
the transport position and the adjustment valve can act
as the hydraulic lock.
Note: When traveling a long distance with farm machinery, they should be locked with the hydraulic
valve to prevent the distributor control handle from being touched during the course of driving to avoid an
accident.
