          POWER STAK  

Electric 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

, the handle will spring back 

to 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 

release your 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.
