Now you should put the rubber retainer ring onto the downtube followed by either
the ceiling trim or ceiling mount cover. This is to allow the covers to be fixed into
position after you have attached the downtube to the ceiling plate.
Thread the wire back up through the downtube and feed it up through the middle of
the ceiling plate; then place the downtube loosely between the clamps on the ceiling
plate.
Next you will need to drill the safety bolt hole. Before drilling, please direct the boot
on the bottom the downtube toward the centre of the examination area to allow the
best range of motion over the examination area.
With the downtube directed, use the two holes in the metal clamps to mark the
location where the safety bolt will go through. Remove the downtube and secure for
drilling. A 6mm hole should be drilled through the downtube on both sides to allow
the bolt to pass through.
Re-insert the downtube into the ceiling plate, insert the safety bolt through the
clamps and the downtube (being careful not to catch the wire). Then tighten the
clamps and the safety bolt / nylon locknut.
NOTE: TO ENSURE THE USER'S SAFETY, THE SAFETY BOLT AND NYLON
INSERT LOCK NUT MUST BE FITTED PROPERLY
It will be necessary to ensure that the downtube is absolutely vertical to prevent arm
drift. This can be achieved by adjusting the three securing points on the plate, once
adjusted, use the locking nut secure the adjustments. After any adjustment it will be
necessary to check that all fixings are still sound and that locking nuts are tight.
