1.0 Cautions and Safety Warnings 

 

WARNING 

Improper tool use and the failure to follow the correct procedures are the primary root causes 

of tools failures and personal injuries. A lack of training or experience can lead to incorrect 

hardware installation or incorrect tool use. Only trained operators with careful, deliberate 

actions should use hydraulic tensioners. Contact Riverhawk Company with any training needs.  

 

WARNING 

Risk of high pressure hydraulic fluid injection. Riverhawk tools operate under high pressure. 

Thoroughly inspect all hoses and connections for damage or leaks prior to using this equipment.  

 

CAUTION 

Personal injury and equipment damage can occur if the puller screw is not securely engaged 

with the tapered thread of the stud. Proper engagement is achieved when the puller screw is 

tight in the stud and the Tensioner Assembly is free to rotate. 

 

WARNING 

The proper personal protective equipment must be worn at all times. Riverhawk recommends 

at a minimum, safety glasses, long sleeve shirt, hard hat, heavy work gloves, and steel toe 

shoes.  

 

WARNING 

The safety cage MUST be in place and hands kept out of designated areas at all times when the 

puller tool is pressurized otherwise personal injury can occur. 

 

CAUTION 

DO NOT EXCEED THE MAXIMUM PRESSURE VIBROSCRIBED ON THE PULLER BODY. Excessive 

pressure can damage the stud and the puller screw. 

  

WARNING 

Fire Hazard; DO NOT heat when the puller assembly is in place. Personal injury or equipment 

damage may occur. Use of an Oxy‐Acetylene torch is not recommended. 

 

NOTICE 

Do not use more thread locking compound than specified or the nut may be VERY difficult to 

remove at disassembly.
