ASSEMBLY INSTRUCTIONS FOR MODEL 600HDA:

Please read all instructions before attempting to set up your 600HDA mount. The model 600HDA is very rugged;
however, like any precision instrument, it can be damaged by improper use and handling. Please refer to
diagram 1.
The following terms and abbreviations are used interchangeably in these instructions:
Polar axis = right ascension axis = R.A. axis
Declination axis = Dec. axis

ASSEMBLE PIER OR TRIPOD:

Begin by assembling the pier or tripod at the desired observing location.
Pier: Slide the three legs onto the nubs of the base, orienting one leg to the north. Place pier post on the base
and attach the tension rods. The turnbuckles should be drawn tight until the whole assembly is stiff enough to
support your weight without movement. Please refer to Diagram 2.
Adjustable Hardwood Tripod: Remove the tripod from its carrying bag and attach the shelf to each of the three
legs with the knobs provided. Adjust legs to the desired height and spread. Lock in position with the hand knobs.
Be sure that the adapter plate for the 600HDA has been installed on your tripod. Please refer to Diagram 3.

ASSEMBLE MOUNTING TO PIER:

In order to track the motion of astronomical objects, the polar axis must be positioned so that an imaginary line
drawn through the hollow shaft points toward Polaris. At this stage of the assembly process, you want to position
the mount so that it points roughly north. Place the mount into the top of the pier or tripod so that the threaded
R.A. axis hole is on the south side of the pier (opposite the pier leg that you oriented north). Align the holes of the
mount and pier. Screw in the three hand knobs to hold the mount in place.

ALTITUDE AND AXIMUTH ADJUSTMENTS:

Follow these instructions if you want to polar align your mount. If not, you may skip this section and move onto
"Assemble Cradle Plate and Counterweight Shaft". You may make these adjustments with the telescope mounted
or not, according to your preference. If you plan to mount your scope at this stage, refer to the "Assemble Cradle
Plate and Counterweight Shaft" section first.
