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 led 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 left our factory in new condition. It has been in-
spected 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
S E C T I O N 4
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 buttery controls throttle on the upper
part of the handle. When rotating the buttery control towards
the forks, the stacker runs forwards in the forks rst direction.
When rotating the buttery 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 buttery control, it automatically will
resume to the neutral position and the speed of the stacker
will slow down, and come to a stop.

PRESTO OWNER’S MANUAL Page 10 POWER STAK
Turtle Speed Travel:
When the buttery control is engaged forward (toward the
forks) or reverse (toward the operator if the operator simul-
taneously engages the turtle speed button the forward and/or
reverse speed is limited to 50% of full speed or turtle speed.
The operator can engage the buttery forward with the right
hand and engage the turtle speed button with the left hand.
The operator can engage the buttery forward with the left
hand and engage the turtle speed button with the right hand.
The reverse operation is also controlled with either hand.
The turtle speed is maintained only when the turtle speed but-
ton is engaged. When the turtle speed button is not engaged
the unit will operate at full speed. The turtle speed button is
a maintained contact operation.
Electric Brake:
Your stacker is equipped with an electric magnetic brake. The
brake is applied when the handle is in its vertical position be-
tween 10 – 15 degrees and lowered position between 80 – 90
degrees. The brake could be released when you pull down the
handle at any point between 15 – 80 degrees. Always make
sure the brake is released before operating the stacker. When
the stacker is running, you could brake the stacker by raising
the handle to its vertical position or lowering the handle to
its lowest position. Or, to turn the buttery controls in the
opposite direction, the change in direction of the motor will
slow down, stop, and reverse the direction of stacker. When
parked, the handle will spring back to the full vertical posi-
tion with the brake applied and the forks in lowered position.
Reversing Safety:
At the end of the handle there is a large, red reversing bar
(belly button switch) that is designed to protect the operator
from injury. When the operator runs the stacker backwards,
and the end of the handle comes in contact with the opera-
tor’s body, the stacker will automatically reverse direction
and travel away from the operator. When the reversing safety
bar comes in contact with your body during operation, im-
mediately release your hands from the buttery control
and put the handle up to its vertical position or down to its
lowest position and the brake is on. The reversing safety bar
will automatically resume to its original position after being
activated.
Horn:
As standard equipment, a horn that is located on the top of
the handle.
AUTHORIZED OPERATORS SHOULD READ
AND UNDERSTAND ALL INSTRUCTIONS,
PRECAUTIONS AND WARNINGS.
IMPROPER USE OF THIS LIFT TRUCK COULD
RESULT IN INJURY AND/OR
DAMAGE TO LOAD AND EQUIPMENT.
• Inspect the lift for damaged or worn parts. Do not use
if not in safe operating condition.
• Use lift on hard level surfaces only.
• Make sure load is evenly distributed, not loose or un-
stable, and is as far back on platform or forks as possible.

MAINTENANCE
Operation of Presto Power Stak is very simple — as is their
construction. They require very little maintenance. Reason-
able care will result in excellent trouble-free performance.
The Power Stak is designed for one-man operation and ease
of performance.
• Grease oor wheels and casters at least once a
month
• Use only Hydraulic Oil AW32 or Dextron III in
the hydraulic system.
• Do not overload your lift.
• Check brakes, steering mechanisms and controls
before each use.
A. WEEKLY OPERATIONS
MAINTENANCE CHECKS:
DAMAGE: Check for bent, dented, worn or broken parts.
LIFT SYSTEM: Check to assure that there is no binding or
excessive play in the forks. Check for quiet and smooth opera-
tion of the lift cylinder. Check all moving parts and linkage.
LEAKS: Check hydraulic system for leaks and hydrualic
oil level.
WHEELS AND CASTERS: Check for wear and that they
are turning smoothly.
LIFT CHAINS: Check to see that they are in place and not
loose.
FORKS: Check that they are not bent or cracked.
BRAKE: Ensure the brake works properly.
CABLES; WIRES: Check that there are no loose cables
or wires.
LABELS: Ensure all precautionary labels and guards are
in place.
B. MONTHLY OPERATIONS
MAINTENANCE CHECKS:
1. Battery (maintenance free)
A. Clean terminals.
B. Clean battery compartment area if there are signs
of corrosion.
2. Hydraulic System
A. Clean and inspect hydraulic cylinder.
B. Lubricate chain with a rust inhibitive lubricant
(light machine oil).
C. Check chain tension. It should be even on both
chains. The chain should be tight enough so that
it does not come off of the roller assembly.
3. Frame Assembly
A. Clean and lubricate all roller bearings, cam fol-
lowers and all moving parts.
B. Clean and inspect all welds.
C. Check wheels for wear and damage.

electrical conductors and connections.
CAUTION:
DO NOT USE LIFT IF IT IS NOT
OPERATING PROPERLY,
OR APPEARS UNSAFE IN ANY WAY!
