• Check all connections for tightness. Is there
hydraulic uid visible?
• Check base frame for dimensions and struc-
tural integrity.

B. REMOVING FROM PALLET:
Remove all packaging materials prior to remov-
ing the lift from the pallet. Visually inspect the
lift as closely as possible.
Carefully pick up the lift taking into consid-
eration the center of gravity of the lift with an
overhead hoist or forklift. Use a hoist and nylon
sling with a minimum of 2,000-lb capacity if you
choose to pick the lift up with an overhead hoist.
Pick the lift up by the top cross member of the
lift. Have all personnel completely cleared from
the area because the lift will begin to swing when
it is clear of the pallet.
Pick the lift up approximately six inches above
the pallet. Once raised and secure remove the
pallet from below the lift then lower the lift.
