          POWER STAK 

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 oc

-

cur 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 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 

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 stacker correctly. 

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.
