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).
