WARNING!
As the platform moves up and down,
“pinch points” are created as shown
in Fig. 2. STAY AWAY FROM THESE
PINCH POINTS! Part of your body or
clothing may become caught, and
you may be hurt. Do not put your
hands or feet under the platform. Do
not stand or sit on the platform.
2. Before lifting, be sure the pallet is pushed
up against the back of the unit. Be sure the
fork lift or pallet truck is clear of the unit
before you begin lifting.
3. Plug in the electrical cord. Be sure the cord
cannot become caught in the moving parts
as the platform rises.
4. Operate the unit. Press and hold the Up
button to raise the platform, and Down to
lower it. If the unit does not operate right
away, unplug the power cord and call a
qualified maintenance worker.
WARNING!
If you hear a squealing noise from the
pump, the pressure relief valve is
operating. DON’T CONTINUE TO
USE THE UNIT! The pump will
overheat very quickly, and may be
permanently damaged. The relief
valve is included to protect the
machine operators - DO NOT
CHANGE THE SETTING ON THE
RELIEF VALVE. If you do change the
setting, this may cause a hydraulic
part to fail. The platform may drop
suddenly. Someone may be hurt, and
the unit and load may be damaged.
The hydraulic parts in the unit are
designed to handle a certain amount
of pressure. The relief valve has
been included for the protection of
all of the workers who use the unit.
