Adjusting the Bottom Roller Wheels

Frequency: As required – check adjustment regularly. 
Tools required: 4mm & 5mm Allen Key, 13mm/16mm wrench
Check regularly the adjustment of the bottom roller wheels for optimal performance and prolonged life of the 
wheels and rail coating. The dynamic frame should be free to move back and forth quite easily. If the moving unit 
becomes loose, or wobbly then tuning the bottom roller adjustment is necessary.
Follow the steps outlined below to get the best perfomance from your DX. 

1.

 

Using the 5mm allen key, loosen both front and rear 

wheel axle bolts on the left hand and right hand side 

plates. Loosen bolts about a 1/2 to 3/4 turn.

3.

 

Repeat loosening procedure in Step 2 for the 

front roller adjuster .

4.

 

Using just the 4mm key, loosen both front and 

rear rollers in an 

anticlockwise direction until the 

front assembly moves loosely along the rails.

2.

 

Locate the adjuster bolts on the underside of the 

front assembly. Insert the 4mm allen key into the socket 

of the rear adjuster bolt and while holding steady in 

position, use the 13mm end of the 13mm/16mm wrench 

to loosen in a 

clockwise direction, the roller adjuster 

locking nut about a 1/2 turn.
