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.
