(8) If restart a tractor being cold or being stored for a long time, loosen the air-releasing screw in injection pump, press with hand the Handle-2 of the pump, and tighten the air releasing screw after the air is released.

  • Page 20: Steering Of The Tractor

    C. Steering of the tractor a. Tractor steering is actuated by steering the wheel. A sharp-turn is allowed only at lower running speeds. On farm working (especially in paddy field ),one-side-braking can be used to promote productivity and maneuverability by reducing turning radius. While working at higher speeds or in transportation, it is forbidden to make a sharp-turn with one-side-braking to avoid of turning-over of the tractor.

    c. Notices in driving. 1. The readings of the gauges should always be noticed. The readings of oil gauge should be within 196--343 Kpa (2--3.5 Kg/cm ); that of the water thermometer within 70--90 C; that of the ammeter in middle position, or "+" direction of charging. If any of the gauges is out of order, it should be repaired or changed, and never be remained in service.

    adjusted before leaving the manufacturer. It is unnecessary to change them. Working on farm, the implement should be lifted up before the tractor turns, and lowered only after it has turned and is running in straight line. The draft control handle does not permit to lower the implement on hard ground, which could destroy the handle due to high speed lowering.
