If the emergency lower is used due to a machine
defect, do not use the machine. Contact your local
Snorkel representative.
Warning
If the emergency lower is used, the top and bottom
booms must be fully extended then fully lowered
before work can continue.
After emergency lowering, any further powered
lowering could cause an airlock in the hydraulic

All booms must be fully extended/raised, then low -

• Move the platform raise/lower levers to the required
direction of movement and operate the hand pump.
• Continue pressing down on the platform raise/lower
levers when the machine starts to lower.
