Ver. 1.05

 

 

In the configuration illustrated in Fig 14, the tool can be collapsed in length and put into the carrying bag completely 

assembled and ready to go!  If other orientations of the handle are preferred, simply remove the handle (replacing the 

bolt and washer in the end for safe keeping or in the bit pouch) and put the handle inside of the carrying bag.

 

 

 

 

 

To adjust length of extension Handle

 

 

Loosen the extension handle knob by two turns and rap it sharply inwards to release it.  Slide to a comfortable length 

and tighten.  

Hint: 

Tool must be lifted completely after each screw driven, try checking the height based on the bottom 

stroke of the tool as well as the top to determine the best adjustment for you.

 

 

Maintenance and Inspection of CH7390

 

 

For best results keep your CH7390 Ultra Driver Clean and Free of dirt and debris for smooth operation.  Blow out or 

vacuum it after use.  Built up dust and dirt may cause feeding problems.  To clean the screwdriver, use a damp cloth or 

soap and water damped cloth, do not use thinners or gasoline or other solvents that would damage the unit, or fully 

immerse  it  in  water  which  may  cause  rusting.    Bits  are  consumable  and  must  be  replaced  if  worn  badly,  bits  are 

specially designed for the Muro auto feed screwdriver. PN SQR28118 and Muro square drive screws will give the best 

service life.  Worn out bits may cause poor countersinking or damage the screw heads.
