          POWER STAK  

The battery operated stackers are very powerful lifts capable 

of doing large amounts of work.  

DO NOT OPERATE THESE LIFTS WITHOUT CARE-

FULLY 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 mainte

-

nance 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 

possibility 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 plat-

form.

• 

Do not stand underneath the forks or platform.

• 

Do not stand in front of the stacker while in mo-

tion.

• 

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 stacker correctly. Read and 

obey all warnings and instructions in this manual and on 

the stacker. It is your responsibility 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. Oper-

ate at a speed that allows you to stop safely. Be even 

more careful on slippery or uneven surfaces. 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, dock-

boards 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. Perform all stacker 

movements smoothly and at a speed that will give you 

time to react in an emergency.

• 

Keep your hands and feet away from all moving 

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.

use this stacker until you have been trained and 

authorized to do so.

structions.
