OZ Lifting Products OZ500EC Manual Del Operador página 9

Only use the OZ500EC when it is in a naturally suspended condition. The body of the chain hoist is
designed to be suspended from a hook or a trolley. It swings very slightly along with the rotation of the
polygonal load sheave. This transmits drive force to the load chain.
Impeding this natural swing could cause injury or damage. If while lowering the load it begins to
swing, stop the hoist until it subsides.
NOTE: The motor and the body of the OZ500EC can be hot both during and after use.
Operating the pushbutton switches
1. Before using the OZ500EC, check that the pushbuttons operate smoothly.
2. Push in the pushbutton firmly until you feel a response.
NOTE: Do not operate the hoist if it moves in the reverse direction to that indicated on the
pushbutton switch.
3. Push the pushbutton firmly to the position where a response is felt, and then
promptly release. Do not operate the hoist with the pushbutton held in a half-pressed condition.
4. After operating, return the pushbutton switch case to the position where it hangs down naturally
from the hoist before releasing it. This is to prevent unforeseen damage or a malfunction.
5. If you need to reverse operation, first allow the suspended load to stop, and then proceed. Abrupt
reversing can impact the life of the hoist.
Keep the vicinity of the pushbuttons clean to prevent the accumulation of dust and sand.
If the event that the pushbutton switch unit is cracked, damaged or extremely dirty, contact your
OZ Lifting Products LLC® dealer for a replacement.
If the reinforced plastic case of the pushbutton switch unit is exposed to a high temperature, it is liable
to become deformed.
