4.  When you are finished operating the die 

grinder, before storing it disconnect the air 
hose and place 4 or 5 drops of air tool oil 
into the air inlet; re-connect the air and run 
the tool for a few seconds to distribute the 
oil.  

5.  Avoid storing the grinder in very humid 

locations which promotes rusting of internal 
mechanisms, and always oil it before 
storage. 

Air Connection 

1.  Make sure that the air compressor supplies 

clean air at the correct CFM for the die 
grinder. 

 

Excess air pressure and/or 

unclean air will shorten the tool’s life and 
may create a hazardous situation.

 

2.  Set air pressure to 90 psi.  

3.  Drain the water from the air compressor tank 

daily, as well as any condensation from the 
air lines. Water in the air line may enter the 
tool and cause damage. 

4.  Change filters on the air system on a regular 

basis. 

5. Air line pressure should be increased 

accordingly to compensate for extra long air 
hoses (usually over 25 feet). Inside diameter 
of the hose should be a minimum of 3/8”. 

 

Troubleshooting 

Trouble Probable 

Cause 

Remedy 

Die Grinder does not 
operate at normal 
speed. 

Air pressure is too low. 

Adjust air pressure to 90psi. 

Air lines are twisted, or there is a 
blockage in them. 

Untwist or clean out air lines. 

Air compressor is malfunctioning, or is 
not sufficient capacity for the tool. 

Replace air compressor. 

Air regulator is malfunctioning. 

Have regulator repaired or replaced at 
an authorized service center. 

Stops operating. 

No air pressure. 

Check air compressor and hoses. 
Make sure compressor is set at 90psi, 
and air lines are not twisted. 

Trigger or throttle valve is 
malfunctioning. 

Have throttle valve/trigger inspected 
and repaired at an authorized service 
center. 

Torque is diminished. 

Air leakage. 

Check connections at the air inlet, o-
rings, etc. Make adjustments/repairs 
as needed. 

Starts immediately as 
soon as air is 
connected without 
trigger being pressed. 

Throttle valve or trigger are 
malfunctioning. 

Inspect and repair throttle valve 
and/or trigger. 

Abnormal vibration 
and/or excessive 
heat develops in the 
tool. 

Improper lubrication. 

Lubricate properly according to 
instructions in this manual.
