ASSEMBLY OF THE COMBINED DRY FOAM FRISBEE/DUSTSCAN DS100 GAUGE
Each kit consists of :
The long PVC tube is normally packed inside the tripod to protect it from damage during transit, and the smaller items can be found in one of the sample bottles. The lower part of the dustscan attachment is fastened lightly onto the top of the tripod central tube.
After unfolding and erecting the tripod, the lower dustscan attachment should be loosened and slid down the central tube of the tripod, followed by a mounting cylinder, and then the upper attachment (which also forms the rain hood). The long and short PVC tubes should be joined (push-fit) and inserted into the tripod tube, from the top. (The black 100mm long spigot is the top of the plastic tube.) The collector/bird guard assembly is pushed into this black PVC spigot at the top of the tripod. It should penetrate about 70mm, at which stage the aluminium boss of the bird guard will bottom on the spigot. This assembly should then be locked in position using the black knob on the side of the birdguard. Now slide the upper dustscan attachment upwards until its top touches the base of the birdguard and then raise the mounting cylinder and bottom dustscan attachment until the cylinder is correctly located between the two attachments. Lock the lower attachment, in the desired orientation, using the 2.5mm Allen key provided. This lower attachment will now not need to be moved again. Now fit the sticky pad as instructed by DustScan. To remove the mounting cylinder at the end of the sticky pad sampling period, the bird guard assembly and the upper dustscan attachment should be removed, after which the cylinder can be removed and stored.
The frisbee-shaped collector is fixed to the bird guard by a grub screw - this can be loosened if you need to remove the collector from the bird guard. In order to remove the collector, it is first necessary to slacken the nylon filament of the bird guard. This filament is threaded through the holes in the stainless steel rods except at its final location. Here it is merely hooked over the rod. The free ends of the nylon filament have been left deliberately long so that the location of the hooked-over piece can be seen. The foam particle trap can be removed with or without this filament slackened.
