I. LEVELING CARRIAGE
WARNING !
When running the unit before ALL limit switches are installed, be prepared
to disconnect power on demand. Allowing carriage over-travel in either
direction can result in severe damage to the equipment and potential injury
to standers-by. Temporary power must NOT be used.
1. Make sure the carriage is free to rise about six (6) inches. Check to be sure carriage
is level and chains are equally tight.
2. Continue to raise carriage in small six (6) inch increments, checking for binding or
interference. Make any changes necessary to align beams to allow smooth travel.
3. Stop carriage at the upper level and check to make sure it is level and that there are
the same number of chain links between the wheel guides & lifting sprockets. DO
NOT attempt to tighten or loosen chain with the carriage in the raised position.
4. Lower the carriage in small increments. Watch again for adequate clearance
throughout the travel, checking for interference or binding of the chain and carriage.
CAUTION!
All chains must be fully engaged with the teeth of all chain sprockets
before operation begins. Chains which jump the sprockets during
tensioning can cause permanent damage to the lift
