VPL400-X: SECTION 7
EMERGENCY LOWERING
PROCEDURE
Never exit an elevated plaorm unless it is fully
parked at a landing. Do not aempt to manually
lower the device while in the plaorm.
WARNING
!
In the event that the lift becomes disabled with
passengers on the platform that is not at a landing,
it may be necessary/desirable to manually lower
them prior to a technician arriving.
In that case, a manual lowering mechanism is
located beneath the top cap of the lift. A person
other than the lift passenger(s) will be required to
make their way to the top of the tower to perform
this procedure.
1. Use disconnect to remove all power from lift.
2. Loosen seven (7) screws around the
perimeter of the top cap with a Phillips head
screwdriver.
3. Flip the brake release switch up to make
lowering easier.
4. Remove the two wingnuts holding down the
manual lowering tool. See Figure 7-4.

power the drill in the forward direction -
rotating clockwise to lower the platform.
Do not use an impact or hammer drill to run the unit
manually. Please us a drill at low speed or socket/
ratchet or manual wrench to avoid damage to the
motor.
CAUTION
!
NOTE: The drive motor is equipped with a low holding
force brake to prevent the platform from drifting with
heavy loads. Lowering the platform with this brake on will
require a bit of strength, typically the equivalent of being
able to lift 20 lb with one arm.
7. Rotate the motor shaft clockwise to lower
the platform.
NOTE: Do not attempt to raise the platform. The required
torque to do so is substantially higher.
8. Stop rotation when the platform is level with
the lower landing.
