OPERATING INSTRUCTIONS
The
hoist
is very simple to operate. The button on the control unit is pushed in and held to
activate the switch which turns the electric motor on (Fig. 16). The motor operates an
internal pump that forces hydraulic oil into the
hoist
piston, which extends the roller chain
and raises the
hoist
. As the
hoist
rises, an internal safety latch will pass over the steel stops
(rectangular blocks which protrude from the back, inside of the column), and you will hear
“clanks” as it does so. This sound is normal, and indicates that the safety latch is passing
over the stops properly. The
hoist
is raised to the desired height by holding the button
in while it is rising, and releasing the button when the
hoist
has reached its desired
position. To lower the
hoist
, you must hold down the lever to depress the release valve, at the
same time as you pull out and hold the safety latch cable (Fig. 17). The weight of the
hoist
will
cause the
hoist
to lower by gravity. No power is required to lower the
hoist
, but the safety
latch must be disengaged to allow the
hoist
to lower past the stops. Occasionally the
hoist
may be resting on a stop, which prevents the safety latch from being disengaged. When this
happens, simply press the “up” button momentarily, to “bump” the
hoist
upwards slightly,
which takes the weight off of the safety latch. Now you can pull the release cable, and
again depress the release valve handle to lower the
hoist
. The safety stops do not engage
at lower levels, so you do not have to pull the safety latch cable to lower the
hoist
when it is
close to the floor. After the installation is complete, raise the
hoist
about two feet and then
lower it. Repeat this process two or three times, and then top off the hydraulic oil
reservoir again, if necessary. This assures that hydraulic oil is distributed everywhere in the
system that it needs to be.
NOTE: Only top off the reservoir with the
hoist
in the “down” position. If you fill
the reservoir in the “up” position and then lower the
hoist
, there will
be too much hydraulic oil in the system, and it will squirt out of the
top of the control unit.
