Adjusting the Bottom Roller Wheels

6.

 

Test the movement of the front assembly along 

the rails. It should move freely along the rails but 

tight enough to have a stable connection to the rails. 

Make small adjustments to tighten or loosen the roller 

tension.

8.

 

Repeat the same process in steps 5, 6 and 7 for 

the front rollers. 

TIP: The front rollers can be adjusted slightly looser 

than the rear rear rollers. 

9.

 

Test row the DX after adjustment and adjust 

tuning again if necessary. Finally, tighten the axle side 

bolts on both side of the front assembly. 

5.

 

Starting with the real roller adjuster, use the 4mm 

allen key to turn the adjuster bolt in a 

clockwise 

direction. Tighten the rollers until they make firm 

contact with the rails. 

TIP: Do not over tighten the adjustment. The 

frame should roll freely without excessive friction. 

Overtightening will cause the rolling frame to be 

slow and require extra effort to return the machine 

during the recovery.

7.

 

Lock the rear roller adjuster by inserting and 

holding the 4mm key in a steady position in the 

adjuster bolt. If the adjuster bolt turns while 

tightening it will alter the adjustment. Using the 13mm 

wrench, tighten the locking nut in an 

anticlockwise 

direction.
