Warm-up procedure for Transmission-Hydraulic Oil in Cold weather

Steering,transmission and hydraulic systems are slow to function when a tractor is started in cold weather.

1. Connect the jumper hose (A) ends into the hydraulic couplers of aux valve 1, as shown in Fig.

2. Apply parking brake, and assure tractor F/R shuttle, speed and range transmission levers are in neutral.

3. Operator should not engage F/R shuttle, speed and range transmission levers until the warm-up process is completed.

4. Start the engine and idle at 850 RPM for 2 minutes, and then slowly increase RPM to 1500.

5. Move the aux lever 1 (B), as shown in Fig. in raise condition (rearward) until oil warms to operating temperature.

6. To check warm-up progress, turn the steering wheel side to side. When the wheel turns smoothly, without hesitation, oil has warmed up sufficiently to operating temperature.

7. After warming up, gradually increase the engine RPM to high Idle for a minute.

8. Return aux lever 1 (B) to neutral position.

9. Remove jumper hose (A).

Overheated hydraulic oil may cause personal injury and component malfunctions. To prevent hydraulic oil from overheating, DO NOT hold aux valve lever in operating position for an extended period beyond that the required for warm-up.

All electrical lamps to be in off condition during idling. It is required to do idling at lower speed only, however increase the engine speed above 1500 rpm after 10-15 minutes during idling
