Notes on trial operation
After initial installation of the hoist and before each day’s use,
perform trial operation to make sure that the hoist functions
satisfactorily.
Check of voltage
Check supply voltage before every day use. Should the voltage
be not within plus or minus 10% of the rated voltage electrical
devices may not function properly.
Check of control button
Make sure that depression of Òbutton lifts the load chain and
depression of Ñ button lowers the chain.
Tips for Safe Operation
1. Friction clutch
The KITO FALCON electric chain hoist is equipped with a built-in
friction clutch as the overwinding protection device. This clutch
eliminates complex electrical circuitry unless otherwise necessary
and its simple construction reduces troubles to minimum if such
happens.
However, overloading or other improper use of clutch may result in
poor hoisting and retaining of the load.
1-1 Do not overload the hoist
When the hoist is overloaded in excess of the torque, the friction
clutch provided slips to allow the motor by itself run free to
protect the other parts. However, if the hoist is overloaded
close to the slip torque and if the load is forcibly lifted with
the clutch slipping, the load, once lifted, may fall. This kind
of use is dangerous and must be prohibited.
The friction clutch is not an overload protection device. Always
make sure before lifting that the load to be lifted is within the
capacity of the hoist.
1-2 Do not overwind
When the cushion rubber hits the chain guide and when the chain is
overlifted or overlowered, the friction clutch slips to make the
