SAFETY
You must be trained and certified to operate this
powered stacker. Federal law states that only prop-
erly trained operators are permitted to operate a
powered industrial stacker and that your employer
must train you and certify that you are qualified.
(OSHA 1910.178 29QFR-7-1-06 Edition)
Presto lifts does not offer operator training. Op-
erator training programs may be offered by your
local Presto Lifts dealer or obtained online. Enter,
"powered industrial truck operator training" into
a search engine.
The battery operated stackers are very powerful lifts
capable of doing large amounts of work.
DO NOT OPERATE THESE LIFTS WITHOUT
CAREFULLY READING THIS MANUAL. In order
to provide for the safe operation of these stackers,
Presto Lifts Inc. has identified certain hazards that
may occur during the maintenance and use of these
lifts. For safety reasons these units are designed to be
serviced or repaired in the fully lowered position. If
performed properly, this will greatly reduce the pos-
sibility of injury.
WARNING!
When servicing the unit:
1. Key should be in "OFF" position.
2. E-stop should be depressed.
3. Disconnect the batteries at the terminals.
• Do not perform any repair work on lifts if
there is a load on the forks or platform.
• Do not perform any repair work if the forks
or platform is in the raised position.
• All personnel must stand clear of the lift
while in motion.
• Do not put hands or feet under the forks or
platform.
• Do not stand underneath the forks or plat-
form.
• Do not stand in front of the stacker while in
motion.
• Do not stand, sit or climb on the lift.
• Do not use the lift on soft, uneven or unstable
surfaces.
• Do not exceed the load center or capacity.
WARNING!
You or others around you can be seriously injured
or even killed if you don't use this stackercorrectly.
Read and obey all warnings and instructions in this
manual and on the stacker. It is your responsibil-
ity before starting work to make sure it is in good
working order.
Always be alert to the area around you and watch where
you are walking. Be careful that you don't get pinned
or crushed between the stacker and a fixed object such
as a wall or post.
• Watch your hands and feet. A foot or hand
caught between the stacker and a fixed object will
be crushed or even cut off.
• If traveling forks first, keep both hands on
the control handle and be careful when changing
direction of travel. Keep your feet clear of the
stacker.
• Keep the stacker under control at all times.
Operate at a speed that allows you to stop safely.
Be even more careful on slippery or uneven sur-
faces. Do not run over objects on the floor.
• Perform all stacker movements smoothly and
at a speed that will give you time to react if an
emergency occurs.
Tipovers and falls are very serious accidents; you can
be crushed or even killed. To prevent injury, know
where you are at all times and follow the rules of safe
stacker operation.
• Be careful when working around docks,
dockboards and trailers. Stay away from the
edge of docks and ramps. Check to make sure the
wheels of truck or trailers are chocked.
• Travel with the load or forks close to the
ground. Watch for overhead obstructions. Per-
form all stacker movements smoothly and at a
speed that will give you time to react in an emer-
gency.
• Keep your hands and feet away from all mov-
ing parts such as masts, chains, forks or wheels.
• Never stand on or under the forks, or allow
anyone else to stand on or under them. Never ride
on the stacker or allow anyone else to ride. There
is no safe place to sit or stand.
• Before you leave your stacker, be sure to
lower the forks to the floor. Shut the stacker off
with the key.

and that the lift is complete. Presto tests and inspects
every piece of equipment 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/hy-
draulic power pack.
• Check all electrical and hydraulic connec-
tions 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

OPERATION
A. OPERATING INSTRUCTIONS:
Operational Speeds:
the Presto Power Stak is designed to operate at the
following speeds:
Rise speed empty: 24fpm
Rise speed loaded: 17fpm
Lowering speed empty: 13fpm
Lowering speed loaded: 31fpm
To Raise and Lower:
There are two buttons located on both sides of the
handle. The inside one is for raising the forks. The
outside one is for lowering 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 pal-
let. 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.
To Travel:
To travel, rotate the butterfly controls throttle on the
upper part of the handle. When rotating the butterfly
control CWtowards theforks, the stackerruns forwards
in the forks first direction. When rotating the butterfly
CCW towards you, the stacker runs backwards in the
handle first 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 capacityof 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 func-
tions like a throttle. When you release your hand from
the butterfly control, it automatically will resume to
the neutral position and the speed of the stacker will
slow down.
To Brake:
Your stacker is equipped with a magnetic brake. The
brake is applied when the handle is in its vertical po-
sition between 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 re-
leased 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 butterfly controls in
the opposite direction, the change in direction of the
motor will slow down, stop, and reverse the direction
of stacker. When parked, always put the handle in the
full vertical position 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 operator’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, immediately
releaseyour hands from the butterfly 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 INJURYAND/OR DAM-
AGE
TO LOADAND 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 unstable, and is as far back on platform
or forks as possible. Do not pick up loads on tips
or forks or edge of platform.

that covers the unit.
4. Remove the emergency stop button by unscrew-
ing.
5. Slide the main cover upand place theblock ofwood
under the right hand side to hold open exposing the
idler wheel and adjusting the screw.
6. With the adjustable wrench loosen the jam nut on
the idler wheel adjusting screw.
7. Loosen the adjusting screw until you have no ten-
sion between the adjusting screw and idler wheel.
You will have some play between the idler wheel
and the left front wheel.
8. Now tighten the screw until you just make contact
with the idler wheel. Continue adjusting until the
idler wheel just touches the floor.
9. Tighten jam nut. You may have a slight rocking
back and forth, from the left front to right rear idler
wheel, but this is not uncommon.
10. Now remove the wooden block and lower the cover
back into place inserting the 2 screws and tighten.
Screw the E-stop button back on.
