Howe v er , adjust this knob bef ore you attach the assemb ly . CAUTION: MAKE SURE THAT YOUR FINGERS ARE CLEAR OF THE TRACK BEFORE YOU SLIDE THE RA ASSEMBLY INTO THE PEDESTAL TRACK.
18 19 20 A TT A CH COUNTER WEIGHT ASSEMBL Y Note that there are two types of counterweights used with Max. One is the typical round counterweight you're probably used with other telescopes; this is the adjustable counterw eight. The other type is uncommon and is called a fix ed counterweight.
23 21 A 21 B Slide the bolts into the threaded holes and tighten each securing knob by hand until it reaches the top . Then use a 1/4" shaft, such as a Phillips screwdriv er , as a le ver , to tur n the knob very tight. Screw in counterw eight shaft into the bottom of the fix ed counterweight assembly until it reaches the hard stop .
