b) TO RAISE the UNDERCARRAIGE.
First the two switched marked "Undercarriage" must be in the UP position. Next the two levers in the right hand quadrant marked "Undercarriage Chassis" must be gripped firmly and pulled backwards and HELD for 3-4 seconds to allow the undercarriage leg to clear the gate, the two levers engage the electric motors NOT the 2 switches. When the undercarriage is raised the two levers will go in and lock the undercarriage UP
c) To LOWER the UNDERCARRAIGE
The two switches marked Undercarriage must be switched to the DOWN position (the undercarriage will not move until the levers are pulled back.) Grip both levers and pull back marked "Undercarriage Chassis" on the right hand side and hold for 3-4 seconds to clear the lock pin gate when undercarriage is down the handles will go forward again they may need a slight push.
d) UNDERCARRAIGE JAM:
Should the undercarriage levers slip and jam the leg, the undercarriage circuit breaker will pop out. Move the undercarriage switch to the middle position OFF. Push the circuit breaker in and momentarily reverse the electrical switch as the lock pin lever is pulled back, then cycle to undercarriage as required.
