WARNING 

The wire rope should be able to go through the inside of the BISOMAC308 freely. 
Inconsistent winding speed suggests the wire rope or the BISOMAC308 may be 
damaged.

 Stop operation at once and replace the wire rope or the BISOMAC308. If it 

is used continuously, the wire rope may be severed or the BISOMAC308 may stop. 
This may cause the platform to fall or tilt, and consequently operators or objects might 
fall, resulting in serious injury, death or damage to operators or passers-by. 

 

WARNING 

DO NOT fasten or apply load to the tail end of the suspension wire rope 
discharged from the BISOMAC308

. Otherwise, the internal parts of the 

BISOMAC308 will become extremely worn and the wire rope may be damaged or 
severed. This may cause the platform to fall or tilt, and consequently operators or 
objects might fall, resulting in serious injury, death or damage to operators or 
passers-by. 

 

CAUTION 

DO NOT put your hand near the wire rope inlet when self-reveeing the wire rope 
and moving the platform up and down.

 Otherwise, your hand may be caught in the 

opening along with the wire rope, causing serious injury. 

 
 
 

CAUTION 

DO NOT throw or drop the BISOMAC308

. The BISOMAC308 may become damaged 

and cannot be used and may result in serious injury or property damage. 

 

CAUTION 

DO NOT pull or step the cables of the safety device. 

Lead the cables and connector to break, BISOMAC308 and Safety Devices cannot be 
used.
