6.4.2.3 LOWERING THE LEADER LIFT DEVICE WITH THE LEADER

• To lower the leader, press simultaneously the "leader lift
device down"-button (5) and the "forward incl. cylinder
release"-button (2) on the right console.
n WARNING
Stop the leader lowering if the signal lights are not
working properly as told before. Do not continue lowering
until you find the reason for that and repair it. Do not
continue the leader lowering if you hear the signal horn
during lowering. Then there is too much pressure in the
forward inclination cylinder. You must not continue
lowering until you find reason for signal and repair it.
n ATTENTION
When you lower the leader with the leader lift device let the engine run at idle. If the
engine stops because it cannot lower the leader at idle then there is something wrong.
Reason can be incorrect position of the leader or the horizontal slide or incorrect idle
speed of the engine. Do not continue lowering the leader until you have found the
cause and can do so at engine idle speed. If you do, you are likely to damage the
machine.
• When you lower the leader pay attention to the ropes and if necessary, wind up the
slack.
• Pay attention also to the location of the hydraulic hoses so that they are not squeezed
between the leader and the base machine.
• When you have the leader down on the support at the rear of the machinery deck,
wind up all the slack from the ropes and check that the hoses lay properly. Do not
over tighten the ropes otherwise the rope rollers of the winches may break down.
• Turn off the power from the leader lift device with the switch (3).
