Mast (6' [1.8m] with 4’ [1.2m] or 6’ [1.8m] carriage)
Capacity:
Maximum lift capacity (indicated on attachment serial number plate) applies
only to certain areas within boom extension/elevation pattern of handler/mast
combination. A separate capacity chart must be used for handlers equipped
with mast. Study and understand this chart before attempting to handle a
load with mast attachment.

Operation:
• Always level handler before raising the boom or the forks, with or without a
load.
• To travel with a load, lower forks fully in mast and lower boom to position
load 4 feet (1.2m) or less above ground, allowing for best visibility.
• Use mast as required to increase vertical reach of handler.
• Use a signal man to assist in positioning the load if necessary.
Swing Forks
Capacity:
Maximum lift capacity for swing forks is shown on the attachment capacity
chart. However, maximum lift capacity applies only to certain areas within
boom extension/elevation pattern of handler/swing forks combination. A

forks attachment.

Do not handle a load with Mast
attachment until you study and
understand the “Mast Capacity
