MAINTENANCE
The 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.
MONTHLY MAINTENANCE
1) Check all welds, making sure they are intact, no cracks
or broken spots.
2) Turn the
PLM 250
on its side and check that the caster
bolts are tight. If the caster with the direction lock requires
tightening, engage the direction lock and ensure that the
castor is pointing straight ahead before tightening.
3) Check that the cotter pins on the actuator pivot bolts are
in place.
4) Inspect the cable and plug for signs of damage.
5) Inspect the battery control box assembly for obvious signs
of abuse.

travel.
