7.2 LIMITED BOOM EXTENSION SWITCH TEST
Australian machines are equipped with a switch (1) on the boom to limit extension
while being operated from platform.
Perform the following to check for proper operation:
1. With platform just above ground level, extend unloaded platform to full
extension.
2. Lower platform to ground, release footswitch and shut-off engine.
3. Exit platform properly.
4. View the boom extension indicators on the side of the boom. The left edge (2) of
the indicator “E” should be visible. If the entire indicator “E” is visible, the system
is not functioning properly.
If the feature does not operate properly, the machine must be removed from service
and repaired before continued operation.
