[When recovering by boom hoisting operation]
In the case of an automatic stop, when hoisting of the boom
is unavoidable, the boom hoist operation is possible only
while keeping the maintenance switch in the “ON” position.
To return to the “OFF” position, also return the boom
hoisting lever.
Only use this switch when an automatic stop has
occurred through entry into the overload region while
lowering or extending the boom.
Do not use under normal conditions or when lifting clear
from the ground.
If you use this switch when lifting from the ground, there
is a risk of serious accidents such as the machine being
damaged or overturning.
NOTES
While the maintenance switch is “ON”, the machine operates
as follows.
• The engine speed decreases.
• The continuous buzzer tone sounds.
• The tri-colour revolving working status lamp illuminates in
red.
