Operation
Warning: OZ500EC operators should read and fully comprehend this
entire manual and all warnings on the hoist before use. If this manual is
not read and followed completely, injuries may occur.
All Persons MUST: Be trained in proper operation and in dealing with potential malfunctions of lifting
equipment. Abstain from use of alcohol, medications, or drugs while operating. Avoid operation while
tired or distracted. Avoid operation if they have a history of seizures or other medical issues that may
interfere with operation.
NOTE: Prior to operation, ensure that the hoist is in proper working condition and maintenance
records are up to date.
Hoisting the Load
To prevent damage and injury, it is vital that the following precautions are adhered to when performing
hoisting operations:
• Never suspend a load that exceeds the rated capacity.
• Do not suspend the hoist from a large capacity hoisting machine to lower a load.
• Do not raise or lower the load at an angle.
Overtravel prevention
This hoist is equipped with an overtravel prevention and overload protection system. When the load
chain end-stop contacts the hoist body, this system will slip, preventing damaging loads from being
applied to the chain. This system will also prevent loads from being lifted that exceed the capacity of
the hoist.
Do not continue to attempt to move the load once the chain end-stop has contacted the hoist and the
overtravel system has engaged. Continued operation in this condition will cause premature wear of
the overtravel/overload system. This system should only be tested during inspection. Do not add or
modify the chain end-stops.
Complete the following steps before raising the load to any significant degree:
1. Move the hoist to a point immediately above the load.
2. Lift the load slightly.
3. When the load chain of the hoist is taut, check for:
• Proper load connection
• Proper load balance
• Proper braking function
