– Repair/Replace Emergency Shut-Off with Pull Cord
IMPORTANT NOTE: Use extreme caution when performing internal servicing on the lift. Ensure
that the battery has been disconnected before starting.
The Emergency Shut-Off/Down with Pull Cord is a safety function that either cuts all power
coming from the battery to the rest of the lift or allows the lift lower. When the cord is pulled and
released the switch activates and all functions of the lift cease to operate. When the cord is pulled
to full extension and held tight, the emergency lower function is activated. Because the
Emergency switch is to be used only in the event of a lift malfunction, it can only be reset after a
qualified technician has inspected the lift. Once the lift has been verified to work properly, the
switch should be pushed in to re-activate all lift functions and restore power from the battery. If
there are no problems with the lift and the Emergency Shut-Off with pull cord is either not shutting
off the power to the lift and/or restoring power to the lift once pressed in, follow the below
procedure to replace the switch.
1. Remove the lift cover per section B1, Getting Access to the C-450/C-625 .
2. Access the Emergency shutoff switch on the lift’s bottom panel (with the strap opening) by
following steps 1 – 10 as per section E5.
3. Verify that the plastic arm with pull cord moves freely and does move the switch lever from
the open to closed, to emergency down position. Second, verify that the wires are
connected. If the switch still does not operate, it must be replaced.
4. Using an M3 Allen Key remove the angle bracket that secures the switch to the bottom
panel.
5. Using you fingers, unscrew the large threaded nut from the switch, to release the switch
from the angle bracket.
6. Cut the cable tie of the switch harness; replace switch, re-assemble and test.
