CARE & MAINTENANCE

The tool should be lubricated daily (or before each use) with air tool oil (not in-
cluded). Air tool oil is available from SGS Engineering. Do not use detergent oil.
During continuous operation, the tool should be oiled every 1 to 2 hours. This may 
be done using an in-line oiler or manually. If done manually, proceed as follows:

1. Disconnect the tool from air supply. (See Figure 6)
2. Place a few drops of air tool oil into the air inlet. (See Figure 7) Avoid the misuse 
of thicker oil which may lead to the reduced performance or malfunction.
3. Connect the tool to the air supply. Run the tool without load for a few seconds 
to distribute the oil through the tool. Any excess oil may be propelled from the air 
exhaust area so point the tool in a safe direction.
4. After operating the tool and before storing the tool, disconnect the air hose and 
place 4 or 5 drops of air tool oil into the air inlet, then re-connect the air hose and 
run the tool to evenly distribute the oil throughout the tool for approximately 30 
seconds. This will prolong the tool life.
5. Avoid storing the tool in a humid environment which promotes rusting of internal 
mechanisms. Always oil the tool before storage. 

OPERATING INSTRUCTIONS

1.  Lubricate the tool before operating. See “CARE AND MAINTENANCE” section 

for oiling instructions.

2.  Release the bolt (Part #32) and washer (Part #31) with the provided hex key by 

turning counterclockwise while holding the provided wrench on the flats of the 
collet holder (Part #25). (See Figure 1)

3.  Mount a cutting wheel onto the tool and re-fix the washer and bolt by turning 

clockwise while holding the wrench on the flats of the collet holder. Make sure 
the cutting wheel is installed securely and tightly. (See Figure 2 & 3)

4.  Remove air cap from the tool air inlet and mount the male plug. Connect air 

supply hose to the tool. Set the air pressure at 90 PSI. (See Figure 4)

5.  Push the lever (Part #03) forward and press down on the trigger (Part #02) to 

start the tool. (See Figure 5)
