1. Grip the lever assembly cover and pull it free to expose the lever inside. There are grooves on either side of the cover
to assist with your grip.
2. Rotate the lever 180º to disengage the worm (never force it past its limits). When you rotate the lever, the motor gear-
box will tilt and disengage the worm from the worm wheel.
Caution: The axis will spin freely when disengaged.
3. When balance is complete,
gently
turn the lever halfway until the spring engages the gear teeth. Shift the axis back
and forth slightly to ensure that the teeth have fully engaged.
4. Once the teeth have fully engaged the lever can be rotated fully into place and the cover replaced.
Do Not force the
lever! No never! Not ever!
VERY IMPORTANT: Begin the balance process in Park 3 position so that there is not an abrupt swing
of an out of balance scope which can damage the worm wheel teeth!!!
Ok...Let’s balance!
1. Be sure that a preliminary coarse balance has been done so that no unexpected swings of the scope take place. Be
sure that the clutches are tight on both axes. You will not use the clutches to balance the mount.
2. R.A. Axis
– Release the gear mesh in the R.A. axis as described in the pictorial above. While holding onto the coun-
terweight shaft, swing the shaft to a horizontal position either east or west to your convenience.
3. Slide the heavier weights to the top of the shaft and try balancing with just the lower, lighter weight. If you must, slide
the weights lower as necessary to balance, however, it is better to add another heavy weight up high. The balance
should be precise for good guiding when imaging.
4. Position the axis horizontally and then gently turn the lever to re-engage the worm and worm wheel as described
above. You may need to slightly rotate the axis so that the gears drop into mesh before fully engaging the lever.
5. Once the lever is fully in its locked position, replace the cover and move on to the Dec. axis.
6. Dec. Axis
– Release the gear mesh in the Dec. axis as described in the pictorial above. While holding one end of the
scope, swing the scope into a horizontal position.
7. Loosen the tube mounting rings or the dovetail saddle locking knobs and position the scope so that it is perfectly bal-
anced and stable in a horizontal position. Remember that the camera should be in its focused position for accuracy.
The balance should be precise for good guiding when imaging.
8. Position the axis horizontally and then gently turn the lever to re-engage the worm and worm wheel as described
above. You may need to slightly rotate the axis so that the gears drop into mesh before fully engaging the lever.
9.
Once the lever is fully in its locked position, replace the cover and you are finished. Now you can loosen the clutches
and reposition the scope into a reference Park position so that you can power up and be oriented.
