RETAIN SAFETY INFORMATION

3

Keep hands and feet away from pinch points such as bending 

shoe, ratchet handle and conduit when operating the bender.

Do NOT leave the ratchet handle in the up position.  

The handle could fall and cause serious injury.

Do NOT force tool. If bend cannot be completed with the  

5' section of 1" RIGID conduit used as a ratchet handle,  

discontinue bend and determine cause before continuing.  

Do NOT use a ratchet handle longer than 5' of 1"  

RIGID conduit.

Do NOT stand on the bender. Serious injury could occur if  

bender is tipped.

ALWAYS keep conduit under control when unloading. Conduit 

not under control could injure the operator or others in the area.

ALWAYS inspect the bender before operating. Replace any  

damaged, missing or worn parts.

WEAR approved safety glasses when using the bender.

Bender MUST be used on a firm, flat surface.  

Do NOT use on an inclined surface.

ALWAYS keep the path of the bending conduit clear of  

obstructions.

Keep firm hand pressure on the ratchet handle while bending. 

The stored energy of bending conduit could cause the ratchet 

handle to spring forward and strike operator or nearby personnel. 

REMOVE the ratchet handle and conduit before moving  

the bender.

Keep firm control of the bender T-handle when moving the  

bender to avoid tipping over.

ONLY use the bender for its intended purpose. Only use the  

bender to bend the specified types and sizes of conduit and pipe.

Bender is heavy and requires more than 1 person to lift.
