SWING FORKS Procedure:
PRECAUTIONS
Read additional capacity information
under Capacity heading.
Always level forks (horizontally) before
swinging load to side. Swinging un-
leveled forks may 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
level (refer to page 19).
Capacity:
Maximum lift capacity for swing forks is shown on
serial number plate (located on right cab wall).
However, maximum lift capacity applies only to
certain areas within boom extension/elevation pat-
tern of handler/swing fork combination. A separate
capacity chart must be used for handlers equipped
with swing forks. Study this chart carefully before
attempting to handle a load with swing fork
attachment.
Do not attempt to handle a load with swing
fork attachment until you have studied
swing fork capacity chart carefully. If your
handler does not have a swing fork capacity
chart, ask your supervisor to get one.
Controls:
The carriage tilt cylinder is used to tilt the swing forks
up and down and the carriage tilt lever controls fork
tilt.
If your unit is equipped with a multi-function
auxiliary control lever, refer to page 30.
The auxiliary control lever is used to swing the forks
to the left and right. Pull lever to rear to swing forks
right and push lever forward to swing forks left.
26
Remove carriage/fork combination or other
attachment from boom head (refer to Attachment
Installation - page 23).
Install swing fork attachment on boom head.
Connect auxiliary hydraulic hoses to swing fork
attachment.
Observe all precautions and load capacity
limits (listed previously) when handling
loads with swing fork attachment.
Always position forks straight ahead before en-
gaging load.
To travel with a load, keep forks in straight ahead
position and lower load to approximately one foot
above ground.
Inspect supporting surface at delivery point and
have it leveled if necessary.
Always bring forks to level (horizontal)
position before swinging load to side.
Swinging unleveled forks may result in load
slipping from forks.
Use a signal man to assist in positioning the load
if necessary.
