Mast (6' with 48" or 72" carriage)
Capacity:
Maximum lift capacity (indicated on attachment serial number plate) applies
only to certain areas within boom extension/elevation pattern of handler/mast

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 approximately one foot above ground.
• Use mast as required to increase vertical reach of handler.
• Use a signal person to assist in positioning the load if necessary.

Maximum lift capacity for swing forks is shown on the attachment capacity
chart. However, maximum lift capacity applies only to certain areas within boom

WARNING !
PRECAUTIONS
• Read additional capacity
information under “Capacity”
heading.
• Because the mast increases
lift height, it is especially
important to level the handler
before lifting a load more than
four feet above ground.
See Page 12.0
WARNING !
Do not handle a load with Mast
attachment until you study &
understand the “Mast Capacity
Chart”. If your handler does not
have a “Mast Capacity Chart”, ask
your supervisor to get one before
using the attachment.
WARNING !
PRECAUTIONS
• Read & understand additional
capacity information under
“Capacity” heading.
• Always level forks
(horizontally) before swinging
load to side. Swinging
unleveled forks could result in
load slipping from forks.
• Because the swing forks can
swing the load to the side, it is
especially important that the
handler be level when
handling a load more than
four feet above ground.
