OPERATOR MAINTENANCE

Scissor Arm - Safety Props

NEVER WORK UNDER AN ELEVATED PLATFORM UNTIL IT HAS BEEN RESTRAINED FROM
MOVEMENT WITH THE SAFETY PROPS, BLOCKING OR OVERHEAD SLING.
BOTH SAFETY PROPS MUST BE USED WHENEVER MAINTENANCE PERFORMED ON THE
MACHINE REQUIRES THE SCISSOR ARMS TO BE RAISED AND ONLY WITH NO LOAD IN THE
PLATFORM.
The safety props are located, one each side of the machine on the scis-
sor arms. To engage the safety props:
1. From the Ground Control Station, raise the platform far
enough to allow the safety props to be engaged.
2. Release the locking pin and rotate the prop on each side of
machine. Always set both when engaging.
3.
Lower the platform until the safety props rest against the
safety prop stops on the arm set below it, stopping all down-
ward movement of the platform/scissor arm assembly.
To disengage the safety props:
1. Raise the platform enough to release the safety props off the
safety prop stops.
2.
Rotate the prop assemblies until they align with the scissor
arm and the release pin locks into the detent disk behind the
arm.
