STEP 9: CABLE MANAGEMENT

1.  If using multiple monitors, first route the cables through the plastic cable clips on  
  the front of the crossbar. If using a single monitor, skip to step 2.

6. Slide the cover down the arm to lock in  
  place, then gently pull the cables  
  through the arm to remove excess slack.

5. Lift the cover and cables up to the lower  
  link, making sure that the cover sits  
  flush with the surface of the arm.

4. Using the two cutouts (D) as guides, run  
  the cables over the lower link cover.

3.  Slide the plastic cover (C) on the lower  
  link upward to remove.

2.  Route power and monitor cables  
  through the flexible cable clips on the  
  M8.1’s upper link (B).

NOTE:

 Leave enough slack in the cables  

to allow arms to rotate without difficulty.

CAUTION:

 Don’t insert extension cords. 

Don’t insert any cord connecting one 
workstation to another.

Your monitor should move up and down easily and stay in place once adjusted. If it is 
difficult to adjust or moves without assistance, it is not properly counterbalanced. 

M10 Arm - Total Weight Range: 20-48 lbs. (9-21.7 kg)
    Single Monitor - Max weight: 48 lbs. (21.7 kg)
    Dual Crossbar - Max weight per monitor: 22.5 lbs. (10.2 kg)
  Triple Crossbar - Max weight per monitor: 10 lbs. (4.5 kg)

1.  To access the Adjustment Screw (E), use your finger to pry open the Cover (D) on
  the Upper Arm Link (C). 

2.  Using the 5mm Hex Key turn the Adjustment Screw (S) clockwise to INCREASE the  
  load tension, and counter-clockwise to DECREASE the load tension. Turn the   
  Adjustment Screw (E) until the Monitor is properly balanced. 

3.  Move the monitor around to ensure that the motion is smooth and the arm functions  
  as intended and holds the monitor in place.

5.  Reposition the Cover (D) and press until it snaps into place. 

CAUTION:

 Do not overtighten the screws as it can damage the screw head or threads.
