GENERAL SAFETY RULES

IMPORTANT SAFETY INSTRUCTIONS

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS

Failure to follow all instructions listed below may result inserious injury.

SA VE THESE INSTRUCTIONS

WORK AREA

1. Keep your viewing area clean and well lit. Cluttered benches and dark areas
invite accidents.

SKU 92444 For technical questions, please call 1-800-444-3353 PAGE 2

PERSONAL SAFETY

1. Maintain labels and nameplates on this product. These carry important infor­mation. If unreadable or missing, contact Harbor Freight Tools for a replacement.

2. Never look directly at the sun with the naked eye or with the Telescope.
Permanent and irreversible eye damage may result.

3. Never use the Telescope to project an image of the sun onto any surface.
Internal heat build-up can damage the Telescope and/or any accessories that
may be attached to it and possibly cause a fire.

4. When using the Telescope , always cover the Finder Scope with the correct
Solar Filter. Although small in aperture, this instrument has enough light gather­ing power to cause permanent and irreversible eye damage.

5. Stay alert. Watch what you are doing, and use common sense when oper-

ating this instrument. Do not use the Telescope while tired or under the
influence of drugs, alcohol, or medication. A moment of inattention while

operating this product may result in serious personal injury.

6. Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the Telescope in unexpected
situations.

PRODUCT USE AND CARE

1. Store the Telescope out of reach of children and other untrained persons.
This instrument can be dangerous in the hands of untrained users.

2. Do not force the Telescope. Use the correct Telescope for your applica-
tion. The correct Telescope will do the job better and safer at the rate for which it
is designed.

3. Maintain this product with care. A properly maintained Telescope is less likely
to malfunction and is easier to control. Do not use a damaged Telescope. Tag
a damaged Telescope “Do not use” until repaired.

4. Check for misalignment or binding of moving parts, breakage of parts, and

any other condition that may affect the Telescope’s operation. If damaged,
have the instrument serviced before using. Many accidents are caused by

poorly maintained equipment.

5. Use only accessories that are recommended by the manufacturer for your

model. Accessories that may be suitable for one Telescope may become haz­ardous when used on another Telescope.

SERVICE

1. Service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury.

2. When servicing, use only identical replacement parts. Follow instructions

in the

“Inspection, Maintenance, And Cleaning”

section of this manual.

Use of unauthorized parts or failure to follow maintenance instructions may
create a risk of injury.

1. The warnings and cautions discussed in this manual cannot cover all pos-
sible conditions and situations that may occur. It must be understood by the
operator that common sense and caution are factors which cannot be built into
this product, but must be supplied by the operator.

2. SA VE THESE INSTRUCTIONS.

PARTS DESCRIPTIONS

1. NOTE: It is recommended that you first familiarize yourself with the main parts of
the Telescope prior to assembling and operating the instrument.

2. Objective Lens (1): The Objective Lens is where the light enters from the
object you are observing. The larger the Lens, the more light the telescope is
able to gather. The larger the Lens, the more able the Telescope is to see farther
objects and get better image resolution (quality). (See Figure A, next page.)

3. Finderscope (2): The Finderscope is used to find your object before viewing it
through the Eyepiece (21, 22). The Finderscope has a lower power than the
Eyepiece, and therefore it is easier to find objects in the Finderscope first.

(See Figure A.)

4. Eyepiece (21, 22): The Eyepiece is the opening on the Telescope where you
view your object. The design of the Telescope allows you to use Eyepieces of
different sizes to change the magnification. (See Figure A.)

5. Focus Knob (4): The Focus Knob is used to move the Eyepiece forward and

back to sharpen the image. An image that is out of focus will appear fuzzy or
blurry. (See Figure A.)

6. Star Diagonal Mirror (5): The Star Diagonal Mirror allows you to view objects
that are at a 90 angle from the direction the Telescope is pointing. The Star

0

Diagonal also allows convenient and comfor table viewing when the Telescope is
pointed at, or near the zenith (i.e., directly overhead). The resulting image is right
side up, but will be reversed from left to right. (See Figure A.)
