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 butterfly controls throttle on the up-
per part of the handle. When rotating the butterfly con-
trol towards the forks, the stacker runs forwards in the
forks first direction. When rotating the butterfly 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 butterfly control, it automati-
cally will resume to the neutral position and the speed
of the stacker will slow down, and come to a stop.
Turtle Speed Travel:
When the butterfly control is engaged forward (toward
the forks) or reverse (toward the operator if the opera-
tor simultaneously 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 butterfly forward with the
right hand and engage the turtle speed button with the
left hand.
The operator can engage the butterfly 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
button 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 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
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 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
