  its.  Consult Powerunit Manual for procedure to set PULL and RETURN pressures. 
*Keep hydraulic system free of dirt.  Avoid letting couplers contact a dirty floor. 
*Do not use as a hammer to force fasteners into holes or otherwise abuse tool. 
*Proper care by operators is necessary in maintaining full productivity and reducing down time. 

*

Check  tool,  all  hoses  and  all  couplings  daily  for  damage  or  air/hydraulic  leaks.  Tighten  or  replace  (if

HYDRAULIC THREAD PREPARATION 
 

WARNING

WHEN

 

TIGHTENING OR LOOSENING HYDRAULIC HOSES, USE A 9/16” WRENCH TO HOLD THE 

HYDRAULIC FITTING TO PREVENT THE STEEL TUBE FROM TWISTING. TWISTING THE STEEL 
TUBE CAN CAUSE PREMATURE FAILURE AT WELDED JOINTS.  

 

 

IMPORTANT:

 

Be sure to use thread sealant on all hydraulic fittings, Loctite® 30534 or similar Teflon® infused pipe  

 

dope is recommended. 

CAUTION:

 

Teflon tape is an excellent thread sealer, however, if it is not  

 

properly  applied, pieces of Teflon may enter the hydraulic system and cause malfunction or damage. 

 

Use 1 1/2  wraps of tape on each thread. Cut off all loose tape ends. Tighten until fitting feels snug and 

 

then go 1/2 to a full turn past  that point. 

CAUTION:

 Over tightening can easily distort the threads.
