6.4.1.3 LIFTING WITH THE LEADER LIFT DEVICE

• Switch power to the leader lift device system with the
switch (3).
• If the signal light (H21) is not on then the horizontal slide
and/or the lateral inclination cylinders are not fully in. The
leader lift device will only move up if the cylinders are
fully in. Press down simultaneously the "leader lift device
up"-button (4) and the "winches/forward inclination
cylinder release"-button (1) and at the same time pull fully
in the horizontal slide and the lateral inclination cylinders.
After that the leader lift device starts moving up.
• If the signal light (H21) is on then start to lift the leader
by pressing simultaneously the "leader lift device up"-
button (4) and the "winches/forward inclination cylinder
release"-button (1).
• Notice that winches are freewheeling when you press the
buttons simultaneously.
• The leader lift device will stop automatically at its top
position or when you release the button(s).
• During lifting check that ropes and hoses are free to rise
with the leader.
• Test releasing valves of forward inclination cylinder according to section 6.4.1.2.
There are two signal lights on the top console which are important when lifting or
lowering the leader.
Green (H41): this signal light is on when the forward inclination cylinder is released
Yellow (H42): this signal light is on when leader is against the leader lift device
n WARNING
Stop the leader lifting if the signal lights are not working properly as told before. Do
not continue lifting until you find the reason for that and repair it. Do not continue
the leader lifting if you hear the signal horn during lifting. Then there is too much
pressure in the forward inclination cylinder. You must not continue lifting until you
find reason for signal and repair it.
n ATTENTION
When you erect the leader with the leader lift device, let the engine run at idle. If the
engine stops because it cannot lift 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 leader erection until you have found the cause
and can erect the leader at engine idle speed. If you do, you are likely to damage the
machine.
