WARNING:
!
Do not leave the joystick in its front lock position unless needed, to avoid hydraulic
pump damage.
WARNING:
!
Leaking fluid under pressure can penetrate the skin causing serious injury. Avoid the
hazard by relieving pressure before disconnecting hydraulic lines. Tighten all
connections before applying pressure. Search for leaks with a piece of cardboard.
Protect hands and body from high pressure fluids. If an accident occurs, see a doctor
immediately or gangrene may result.
To operate a spool control valve, connect the remote cylinder feed hose to the lift coupler by inserting
the hose in the coupling after removing the dust cap. Ensure that the hose is properly seated. The
return hose from the double-acting cylinder must also be connected to the drop coupler.
A second remote cylinder can be connected (on tractor where twin spool valve is installed) after
connection to the second set of couplers.
WARNING:
!
Before connecting or disconnecting hydraulic hoses at the remote couplers, stop the
engine and relieve the pressure in the circuit by moving the joystick fully forward, fully
rearward, side ways and then to neutral position.
NOTE:
Before connecting remote cylinder hoses, thoroughly clean the connections to prevent
oil contamination. Remote cylinders are operated by oil drawn from the tractor
transmission system. Therefore, always check and replenish the transmission system
oil after remote cylinder equipment has been connected and cycled a few times
If hoses are accidentally disconnected from the tractor during use, clean tip and coupler receptacles.
Hoses can be reinstalled as previously described with minimal loss of oil.
WARNING:
!
Make sure that the amount of oil in the gearbox does not fall below the minimum level.
Take special care when cleaning the hydraulic unit on the implement/equipment so as
not pollute the oil in the transmission housing.
4.6. Equipment attaching on three-point linkage.
The tractor hydraulic lift system with three-point linkage (see Fig. 4.6.1) facilitates control of
implements and machines from operator’s place.
The three-point linkage consists of following elements:
1. Top link (1) it is fitted with locking sleeve and lever to adjust the length of the link. It can be
attached to one of three openings in top link rocker (2). When transporting the tractor, hook the
link over the lug.
2. Lower links (6 and 7).
3. Lift rods, right (5) and left (4) attached lower links with lift arms. Both lift rods length is adjusted by
means of rotary handles. To turn the handle pull it upwards to unlock.
4. Stabilizer bars protect implements of excessive lateral movement. The external bars are
adjustable with means of a sleeve nut (8) locking with check nut (9).
5. Quick couplers (3) of lower links and top link are designed to attach implements to three point
linkage.
6. Multi-hole drawbar (10).
