UNDERGUARD SERVICE CHECK
The underguard is a safety device located under the
cage/platform that shuts down operation of the lift
when weight is applied. Perform the following
procedure weekly to verify the underguard is
working properly.
Turn power to lift ON and raise cage/platform
using the lower control box a minimum of 3 feet
above the underguard.
Place a weight of at least 15 lbs. on the
underguard. Refer to Figure 4-1.

BEFORE ATTEMPTING TO LOWER THE LIFT,
MAKE SURE AREA UNDERNEATH AND
AROUND THE CAGE/PLATFORM IS CLEAR
OF PERSONNEL OR OTHER OBJECTS.
Using
the lower control box with power ON, attempt to
lower lift. A warning beeper should sound and
the lift should not lower. The lift should still be
able to raise. With someone in the cage, switch
to upper controls and attempt to drive. A warning
beeper should sound and the lift should not
drive.
If the lift lowers or drives, the switches below the
underguard may need to be adjusted or
replaced. To adjust or replace underguard
switches, shut power OFF to lift, then remove
two of the underguard clamps from one side of
the lift. The switches below the underguard can
be adjusted by loosening the screws or removed
for replacement.
Retest whenever underguard is removed and
switches are adjusted or replaced.
