4. Reconnect the air supply to the impact wrench and run for 20 to 30 seconds. 

Lubricate the entire impact mechanism by rotating the tool upside down and sideways while   
running the tool. 

5. Remove the screw and hold the oil port hole over a suitable container to allow excess oil to   

drain. 

6. If the oil is dirty, repeat the procedure above until the oil comes out clear. Install the screw and 

tighten. The residual oil remaining in the impact mechanism chamber is all that is needed for   
proper lubrication. 

 

General Troubleshooting Guide

 

Symptom  Possible 

Cause(s) 

Corrective 

Action 

Tool runs slowly or 
will not operate 

1. Grit or gum in tool. 
 
 
 
2. No oil in tool. 
 
3. Low air pressure. 
 
4. Air hose leaks. 
 
5. Pressure drops. 
 
 
 
 
 
 
 
 
 
6. Worn ball bearing 

in motor. 

 

1.Flush the tool with air tool oil, gum solvent,   
  or an equal mixture of SAE # 10 motor oil   
  and kerosene. Lubricate the tool after   
 cleaning. 
2.Lubricate the tool according to the lubrication 

instructions in this manual. 

3.Adjust the compressor regulator to tool 
    maximum while the tool is running free. 
4.Tighten and seal hose fittings if leaks are   
  found. 
5-1.Be sure the hose is the proper size. 

Long hoses or tools using large volumes of 
air may require a hose with an I.D. of 12.7   
mm (1/2") or larger depending on the total   
length of the hose. 

5-2.Do not use a multiple number of hoses 

connected together with quick connect   
fittings. This causes additional pressure   
drops and reduces the tool power Directly 
connect the hoses together. 

6.Remove and inspect bearing for rust, dirt   
    and grit or worn race. Clean and regress   

bearing with bearing grease.
