Chain Hoist
Ensure that the following are observed prior to installation:
• Install only in a place where there is no danger of the OZ500EC falling.
• Suspend the hoist in such a way that it swings freely. Failure to do so could result in damage and/or injury.
• Never operate the OZ500EC when the body of the unit is not suspended or when it is tilted to an
excessive degree.
• Remove the vinyl band and the caution tag before operating the chain hoist. Failure to do so could
result in damage.
• Confirm that the load chain has correctly passed through the inside of the body of the unit.
• Confirm that the bottom surface of the body of the unit is separated by at least 12 inches from the
ground to ensure that the load chain can enter and exit the unit smoothly.
• Check the safety latch, and ensure that it is not broken.
Using the chain hoist as a hook suspension type
1. The attachment point to which the top hook of the OZ500EC is to
be attached must have sufficient strength to enable it to withstand a
load of at least 5 times the rated load.
2. The cross-sectional shape of the hook attachment must be adequately
rounded and free of sharp angles. Also, apply grease or another
lubricant to the contact aces of the hook and the ring.
3. Upon completion of installation of the OZ500EC, ensure that the safety
latch of the top hook is completely closed.
NOTE: If the hook attachment point has insufficient strength or is worn, it is liable to break, causing
the suspended load and the chain hoist to drop.
Installing the chain bag
The chain bag should be installed prior to using the OZ500EC.
Incorrect installation may result in damage or injury. Ensure that
the chain bag matches the length of the load chain and do not
insert the entire load chain into the bag at once.
1. To install the chain bag, first run the hoist so that there is
about 6 inches of chain extending from the hoist on the
no-load side of the hoist. This will help to align the bag in
the proper position.
2. Install and secure the two mounting bolts at the top of the bag.
Carry out a hoisting operation so that the chain on the no-load
side enters the chain bag.
NOTE: When using the chain hoist in a very dusty location, in a place where foreign matter is liable to
enter the bag, or when the chain is rusty, the chain may sometimes spill over. Keep the bag and the
chain clean and always keep the chain oiled.
