For recommended hook-up, procedure is shown in figs 1 & 2

.

3.1.  Air Supply.

 

3.1.1. Ensure wrench air valve (or trigger) is in the "off" position before connecting to the air  

 supply.

3.1.2. You will require an air pressure of 90psi and an air flow according to specification.

3.1.3. 

 

WARNING! 

Ensure the air supply is clean and does not exceed 90psi while operating the

 

wrench. Too high an air pressure and unclean air will shorten the product life due to   

 

excessive wear and may be dangerous causing damage and/or personal injury. 

3.1.4. Drain the compressor air tank daily. Water in the air line will damage the wrench. 

3.1.5. Clean compressor air inlet filter weekly. 

3.1.6. Line pressure should be increased to compensate for unusually long air hoses (over 8 

 

metres). The minimum hose diameter should be 1/4” I.D. and fittings must have the same 

 

inside dimensions. 

3.1.7. Keep hose away from heat, oil and sharp edges. Check hose for wear and make certain 

 

that all connections are secure. 

3.2.   Couplings. 

 

Vibration may cause failure if a quick change coupling is connected directly to the wrench.  

 

To overcome this, connect a leader hose to the wrench. A quick change coupling may then  

 

be used to connect the leader hose to the air line recoil hose. See figs 1 & 2.

PREPARING WRENCH FOR USE

4.      OPERATING INSTRUCTIONS

 

WARNING! Ensure you read, understand and apply safety  

 

instructions before use.

4.1.

  Only use impact sockets which are specifically designed for  

 

use with an impact wrench.

4.2.

  Connect the wrench to the air hose as in Section 3.

4.3.

  Place the socket over the subject nut and depress the trigger to  

 

operate the wrench. 

4.4.

  To change drive direction turn the air regulator on the rear of  

 

the body to the desired direction. (fig 3)

4.5.

  The torque may be adjusted in the forward gear by adjusting  

 

the torque control on the rear of the body, between 1 low power  

 

and 3 full power.

4.6.

 The SA297 incorporates two exhausts, one at the bottom  

 

of the handle and one at the front above the trigger (fig.4). The  

 

handle exhaust is adjustable allowing you to adjust the flow  

 

through either the handle or front exhaust. When the handle  

 

exhaust is fully open the speed of the wrench is increased,  

 

when the handle exhaust is closed the wrench speed will  

 

decrease and the air will be vented through the front exhaust.
