WARNINGS
•Do not use telescope or finderscope to look at the sun without
an appropriate solar filter.
•Make sure no screws are loose before using telescope.
•Do not drop, shake, or throw your telescope as doing so may
damage the telescope or people around you.

•Eyepieces intended for external use only.
•Don’t worry, be happy...
Zhumell telescopes are precision astronomical instruments de-
signed to be easy to use and versatile in their application. As with
any telescope, Zhumell telescopes require some technical knowl-
edge of stellar movement and optical properties. We have tried to
provide the basics of telescope use and astronomical viewing in
this manual. If, after reading through this manual, you still have
questions regarding the setup and use of your telescope, please
2063. Our customer service representatives will be able to help
address any problems you are having with your Zhumell tele-
scope. We also have more information available on our website
at www.zhumell.com. Please let us know about your experiences
with your Zhumell telescope. We would like to hear your feed-
back and see your astrophotographs. Enjoy your Zhumell.

CAREOFYOURTELE SCOPE
A telescope is carefully aligned during construction and great care should
be taken to maintain this alignment over the life of the telescope. Cleaning
should be done as little as possible and then only with a mild soap solution
and soft, lint-free cloth. Do not rub elements when cleaning. Blot optical
components gently and allow telescope to air dry. Store telescope in box
when not in use. Do not use alcohol or solvents to clean any parts of the
telescope. Do not remove optical elements from telescope as doing so may
affect the alignment of optical components when reassembled. If telescope
needs realignment, contact Zhumell or another professional.

TELE SCOPE ASSEMBL Y
1. Extend tripod legs to comfortable working
height and tighten wingnuts to ensure stabil-
ity. Separate tripod legs and ensure that the
legs are extended to equal heights. The top of
the tripod should be level to ensure stability
when mounting telescope.
2. Remove accessory tray mounting screw at
the center of tripod leg crossbracce. Set acces-
sory tray on crossbrace, lining us the center
hole of the accessory tray with the raised fit-
ting at the center of crossbraces. Reinsert and
tighten mounting screw.
3. Locate the mount alignment prong extend-
ing up from the north leg of the tripod (la-
belled with an N above the leg). Also locate
the mount rotational stabilization thumbscrews
below the front latitude adjustment screw.
4. Remove the mount base screw. Loosen the
mount rotational stabilization thumbscrews
enough to allow the alignment prong to be
inserted between the bases of the screws. Set
the mount on the top of the tripod so that the
tripod alignment prong is lined up between
the mount rotational stabilization screws.
Tighten rotational stabilization screws so that
the fron mount extrusion is centered over the
north tripod leg. Isert the mount base screw
through the hole in the tripod platform and
hand tighten.
6. Holding the counterweight shaft, turn the
Dec. axis cap attached to the shaft clockwise
(looking at the large end of the cap) until it
stops. Insert the shaft into the counter-weight
shaft socket and screw the shaft into the socket
unti secure. To eliminate the gap between the
Dec. axis cap and the Dec. axis of the mount,
turn cap (without turning the counterweight
shaft) until it is snug with the end of the Dec.
axis.
7. Remove screw located at the end of the
counterweight shaft. Loosen the thumbscrews
on the counterweights until shaft opening in
the counterwiegt is completely unobstructed.
With the thumbscrew pointing down, slide
the counterweight up the counterweight shaft
and tighten counterweight thumbscrew until
snug. Repeat for each counterweight. Replace
the end screw of the counterweight shaft and
tighten until snug.
5. Loosen R.A. and Dec. axes by turning axis
release levers 180°. Position mount so that
Dec. axis is at 0° and R.A. Axis is at 0, then
re-tighten the axis release levers. The mount
should now vertically level. With the mount in
this vertical position, find the counter-weight
shaft socket located at the end of the Dec. axis
above the north leg of the tripod.
8. Loosen the two thumbscrews located at the
top of the mount to allow the optical tube
mounting rings to be inserted in the groove.
Place the optical tube mounting rings into the
groove and tighten the large thumbcrew until
the end of the screw is snug against the optical
tube mounting ring base. Tighten the small
screw against the optical tube mounting ring
base to add stability to the moounting rings.
9. Open optical tube mounting rings by
loosening thumbscrews on side of mount-
ing rings. Lift the optical tube assembly by
the attached handle near the focuser and
set it into the optical tube mounting rings,
guiding it with your other hand. Close the
optical tube mounting rings and retighten the
thumbscrews on the mounting rings to secure
optical tube assembly.
10. Remove nuts from finderscope mount-
ing bolts near the focuser on the optical tube
assembly. Slide finderscope mount over the
bolts and replace nuts, turning them until they
are snug against the finderscope mount.
11. Loosen finderscope mounting screws
until finderscope can be easily slid into the
mount. Slide finderscope into the mount and
retighten mounting screws so that finderscope
is approximately aligned with the telescope.
12. To use a 1.25“ eyepiece, loosen eyepiece
receptacle thumbscrew at end of focuser.
Remove dustcover from eyepiece receptacle.
Insert chromed end of eyepiece into the eye-
piece receptacle. Re-tighten eyepiece recep-
tacle thumbscrew to secure eyepiece.
ASSEMBL YNOTES
In order to avoid visible vibration when viewing at high magnification,
adjust the counterweight position on the counterweight shaft to offset the
weight of the optical tube assembly and balance the telescope.
When placing the optical tube assembly into the mounting rings, center the
rings along the length of the optical tube assembly. Centering the rings along
the length of the optical tube assembly will help to keep the telescope bal-
anced and increase overall stability of the telescope.
13. Enjoy your telescope.

CONNECTING THE HAND CONTROLLER
To use the clock drive, connect the havd controller by plugging the Motor
Connection Cord into the receptacle at the base of the plastic housing on the
R.A. drive of the mount. Place 4 D-cell batteries into the battery pack and
plug the power cord from the battery pack into the Battery Pack Connection
receptacle in on the hand controller. To activate the hand controller, simply
switch the hemisphere setting to the appropriate setting and press the desired
speed and direction button.
