OPERATION
A. OPERATING INSTRUCTIONS:
To Raise and Lower:
There are two buttons located on both sides of the
handle. The inside one is for lowering the forks. The
outside one is for raising 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.
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.
