INSTALLATION
A. INSPECTION
:
Upon receipt of the stacker, inspect the equipment completely
to determine if there is any shipping damage, and that the lift
is complete. Presto tests and inspects every piece of equip-
ment prior to shipment. If damage is apparent, a freight
claim must be filed with the freight company. Do not use the
stacker if there appears to be any damage. With the stacker
in a lowered position, check the following:
•
Check for signs of damage especially to the back
cabinet that houses the battery, electrical/hydraulic
power pack.
•
Check all electrical and hydraulic connections for
tightness.
•
Remove back panel.
1. Turn key switch to "OFF" position.
2. Push in E-stop and unscrew the red knob,
3. Lift off back panel. There is enough wire to the
key switch to allow the panel to be set aside.
•
Inspect for any bent or damaged parts.
B. REMOVING FROM PALLET
PowerStak is shipped out on a pallet or skid. Prior to re-
moving the unit from the pallet or skid, remove all tie down
straps and packaging. Visually inspect the unit as closely
as possible.
With an overhead hoist or forklift, carefully pick up the unit
taking into consideration the center of gravity of the unit.
If you choose to pick the unit with an overhead hoist, use a
nylon sling and hoist with a minimum of 2,000-lb. capacity.
The nylon sling will not do any damage to the steel construc-
tion of stacker. Pick the unit up. On conventional masts use
the top crossmember of the lift. On narrow masts the cover
must be removed to access lifting equipment. Be careful of
the stacker swinging once fully lifted off the pallet or skid.
Have all personnel completely cleared from the area.
Pick the unit up approximately six inches above the pallet
or skid. Once raised, remove the pallet or skid from below
the lift. Do not move the lift around in the air. Lower the
stacker on the ground.
C. PREPARATION FOR USE
PowerStak our factory in new condition. It has been inspected
and weight tested to assure all performance standards have
been met.
Visually inspect the stacker for damage. Check for attach-
ments and accessories that may have been ordered. If there
is any damage or missing parts, report it to your carrier and
your Presto dealer immediately.
Remove all metal/plastic bands, cardboard and other material
used for shipping purposes.
Check to see if chains are in place, and that the lift system is
in working order. Inspect for oil leaks.
Connect battery cable. Check cables and wires on battery
charger as well as battery.
Note: The travel speed is preset at the factory. For
travel speed adjustment, please contact customer
service at Presto Lifts 1-800-343-9322

OPERATION
A. OPERATING INSTRUCTIONS:
To Raise and Lower:
There are two buttons located on both sides of the handle.
The inside one is for lowering the forks. The outside one is
for raising the forks. When operating, always make sure the
load being lifted is within the loading capacity of your stacker
and the load has been stacked safely on the pallet. Also, make
sure that the length of the forks corresponds to the length of
the pallet. In this way, the load rollers will place themselves
in the opening at the end of the pallet, so that when you
raise the forks, you will not break the bottom boards of the
pallet. Always make sure that when entering the pallet that
the forks are in the fully lowered position. Be careful when
lifting pallets that are too short or too long for the stacker.
It might destroy your pallet by breaking the bottom boards,
and if the forks project through the end of the pallet, the tips
of fork may go into the next pallet that is behind the pallet
that you are lifting, which may bend the tips of forks and
overload the capacity of the stacker.
Travel Function:
To travel, rotate the butterfly controls throttle on the upper
part of the handle. When rotating the butterfly control towards
the forks, the stacker runs forwards in the forks first direc
-
tion. When rotating the butterfly towards the operator, the
stacker runs in the reverse direction. Always make sure the
stacker clears any obstruction when traveling, and that your
path of travel is clear of people. Never carry loads above
the loading capacity of the stacker. It is suggested that when
traveling without a load, the forks be in the lowered position.
The speed of the stacker is increased by the degree of the
rotation in either direction; it functions like a throttle. When
you release your hand from the butterfly control, it automati
-
cally will resume to the neutral position and the speed of the
stacker will slow down, and come to a stop.
