PLM 250 — POWERED DANY LIFT
LOAD CAPACITY
The load capacity is stamped into the
identification plate located on the central
cross-member, at the base of the actuator
and capacity stickers on either side of the
table. (figure 4) The PLM 250 contains
an overload protection device that may
cut power to the unit if overloaded. If this
occurs, make sure that the PLM 250 is not
loaded beyond its capacity. The device will
reset within a matter of seconds and power
will be restored. The load capacity is based
on the load applied centrally and uniformly
to the platform.
CAUTION!
Do not overload the PLM 250, as
this may damage the unit.
CAUTION!
Do not let loads significantly
overhang the platform, as this
could result in the platform being
overloaded, and cause the PLM
250 to tip over.
MAINTENANCE
T
he PLM 250 requires minimal maintenance.
The PLM 250 is designed for a life of
approximately 10,000 cycles after which a
new actuator may be required.
Daily inspection: Make sure there are no
foreign objects in the way of the rollers and
the scissor legs. Make sure all wires are
plugged into the control box.
