Bypass Limit Test
Perform the following test to determine if the boom up limit
on your crane can be bypassed or not:
1. Lower the boom onto the blocking at ground level.
2. Have an assistant push in the adjusting rod (Figure 4-2
)
in to open the boom stop limit switch.
3. Rotate and hold the limit bypass key (in the crane cab) to
the bypass position.
4. Try to boom up. Do not raise the boom any higher than
necessary to perform the test:
a. If the boom rises, your boom up limit can be
bypassed.
b. If the boom does not rise, your boom up limit cannot
be bypassed.
5. The test is complete. Release the limit bypass key and
the adjusting rod to the normal operating positions.
WARNING
Crush Hazard!
The weight of the boom will crush you and/or any
surrounding equipment. Stay clear of any moving parts
and maintain clear communications while working with the
boom and boom accessories.
