WARNING:
Never disengage Gear Switches without holding the mount firmly!  Personal injury
and/orequipmentdamagemayhappen.
If the mount motor has “grinding” sound (which is not harmful) while slewing, the Tension Adjuster is too
tight. Release 1/8 to 1/4 turn and check it again. If there is excess play in either RA or DEC axis, or even the gear
is skipping, the gear and worm is not meshed properly. Turn the Tension Adjuster more clockwise. You may
need to readjust the Tension Adjuster for different payload.
