PLM 250 — POWERED DANY LIFT
UNPACKING AND
SET-UP OF THE
PLM 250
HIGH CYCLE APPLICATIONS
The PLM 250 is designed for intermittent use.
For high cycle operations, the following
should be observed:
1) The PLM 250 is designed to achieve a
minimum life of approximately 10,000
cycles. For intermittent use, this
equates to many years of service.
2) The PLM 250 linear actuator should
not exceed six (6) full cycles per hour.
The recommended duty cycle for the
actuator motor is 10%. This means that
the motor should not be operated for
more than 6 minutes of every hour.
OPERATING
THE PLM 250
PLATFORM CONTROL
The position of the platform is controlled
with a push button switch located on the
hand control. The PLM 250 can be raised
by pressing the UP button on the switch or
lowered by pressing the DOWN button on
the switch.
WARNING!
As the PLM 250 platform moves
up and down, “pinch points” are
created where the scissor legs
cross, where the legs meet the
base and platform and in the
path on which the rollers travel.
When operating the PLM 250,
be careful to ensure that nobody
1) Cut the banding straps and remove the
PLM 250 from the box. (Make sure all
of the parts are included before the box
is discarded. Figure 1.)
2) Attach the handle to the PLM 250 by
sliding the two threaded ends of the
handle into the pockets that are welded
to the base frame. Using the lock
washers and the nuts, secure firmly.
3) Locate the battery control box assembly.
Attach the assembly to the handle using
the 4 self tapping screws, making sure
the control box is to the right and
the battery box is to the left. This
allows the actuator to plug into the
control box.
4) Make all the correct electrical connections
(figure 3).
TRANSIT DAMAGE
Inspect the PLM 250 for signs of damage
in transit, paying particular attention to
the electrical cabling and connections. If
there is evidence of damage, contact your
Southworth dealer before using the PLM
250.
HAZARDOUS
ENVIRONMENTS

CASTER CONFIGURATION
The PLM 250 is supplied with four swiveling
casters. One of the rear casters is fitted
with a brake and the other rear caster has
a direction lock.
BRAKE
The brake prevents the caster from both
swiveling and rolling. Press the lever
located on the top of the caster to engage
the brake.
CAUTION!
The brake is an important safety
device. Please ensure it is
engaged when the PLM 250 is
unattended. Attempt to find level
ground whenever possible.
DIRECTION LOCK
The direction lock prevents the caster from
swiveling but allows the caster to roll as
usual. Use it when pushing the PLM 250
in a straight line to provide greater stability.
BATTERY
The PLM 250 is supplied with a 24 volt
battery pack which snaps easily on to
the control box. This allows for a quick
exchange of battery packs if needed. The
control box is mounted to the handle of the
PLM 250 for easy access. The control box
