Sequence of Operation

5.1

Operating Sequence

WARNING: Do not stand behind bucket or put any part of your body under, in, or near bucket when bucket
is raising/tilting or raised/tilted.
WARNING: Machine operation occurs automatically. Do not place any part of the body on or near moving
devices/components of the machine.
WARNING: Do not adjust Gaylord position in bucket when bucket is raised—fully or partially. This can
result in the Gaylord tipping and falling from the bucket, which can cause personal injury. Lower the bucket
if adjustment of the Gaylord is required.
CAUTION: If repositioning the vacuum wand holder, support the vacuum wand holder before loosening
the screw securing it in place. This prevents the vacuum want holder from quickly lowering and potentially
causing personal injury.
NOTICE: Bucket must be flat on floor before loading.
1.
Start with the FLT bucket (A) fully lowered.
2.
Load Gaylord so it fits tightly into rear corner of
bucket (A).
3.
Lower vacuum wand holder (B) into hole on FLT
frame and tighten screw at base.
4.
Insert vacuum wand into wand holder (B) and
into full Gaylord.
5.
Place pedal/hand valve in the inflate position, as
described below.
As weight in Gaylord decreases, bucket lifts and
rotates from floor position. Lifting begins when
cargo weight is less than 900 lbs [408.2 kg] (*)
6.
When Gaylord is empty, place control valve in
deflate position, as described below, to lower the
bucket.
7.
Unload the Gaylord from the bucket.
(*) If the material in the Gaylord has a low flowability or high bulk density, the initial tilt weight may
be affected. More material may remain in the outer corner of the Gaylord, causing the container
to begin to tilt later than expected.
