L-Arm Motion
Circuit/Mechanical Descriptions
The following paragraphs describe normal L-Arm Motion, L-Arm Hazards, and how to check operation of the L-Arm Brake.
L-Arm Motion
Note: There is no L-Arm on the Super C
You can manually rotate the L-Arm on the end of the Cross Arm up to 180 degrees in either direction. Gas-shocked-dampened
springs inside the L-Arm hold it in place when you remove your hand. A rotation indicator on the back of the L-Arm shows its
current angular position. Set the L-Arm brake to secure the L-Arm in position.
CAUTION: Watch carefully when you manually rotate the L-Arm. Even a low-speed collision can result in significant
personal injury or equipment damage.
