1.  Connect the air hose to the air inlet (8) on the grease gun.

 

2.  The grease coupler (37) provided at the end of the extension (38) has a jaw-type construction. 

The coupler jaws will snap on to a grease fitting and maintain a tight fit.  

3.  When connecting the grease coupler (37) to the grease fitting, press the grease coupler (37) 

straight onto the grease fitting to form a snug fit. 

4.  Start operating the grease gun with the grease coupler (37) as aligned to the grease fitting as 

possible. 

5.  This is a continuous discharge grease gun so there will be a continuous grease discharge while 

the trigger (12) is pressed. 

6.  Once greasing is completed, slightly tilt the grease coupler (37), twist, and pull back. 

7.  The tilt and twist action will allow easy removal of the grease coupler (37) from the grease fitting.
