INSTALLATION

1. Install Ring / Bracket Assembly

(Fig.1) Insert the rod into the bottom of the mounting post, then attach handle.

Make sure the washer is under the handle.

Position handle away from stand arm by lifting the handle while pressing the center button.

(Fig.2) This does not loosen the handle. To attach the stand to your work, see Microscope Stand Base Template (page 3). The microscope body sets in the ring and is secured by three thumb screws, included.

2. Install Headrest

After installing the microscope, attach the headrest.

(Fig.3) Make sure white nylon washer is between the T-Knob and the headrest mount. Adjust the angle using the side T-Knob; adjust depth using the top T-knob. The forehead end may also be adjusted.

3. Setup and Operation

After the stand is secured to the bench top, there are many choices for adjustments to fit your needs. Turn tension knobs clockwise to add friction, counter-clockwise to reduce friction.

A. Controls front arm. Tension knob. B. Controls friction during movement of back arm. Tension knob. C. Controls angle of microscope on pivot ball. Loosen to adjust. D. Adjusts focus. Tension knob. E. Locks arm height on the stand rod. F. Controls the drag of the arm swing. G. Tighten for additional arm rigidity.

4. For Wood Top Benches

Decide where to locate the microscope stand on your bench top. Make sure it is plenty of "reach" so the microscope is over your work. Using the template below, tape it exactly where the base will be located. With a center punch or mark the centers of the screw holes through the paper and into the bench top. Remove the template and drill a starter hole for the screws using a 1/8" bit. Drill all four holes a little more than 1" deep. Hold the drill as square to the surface as possible. Attach the stand to the bench with the 1-1/2" wood screws that are included in the package. Be sure to tighten the screws so that the heads are tight against the metal base. If you are having trouble setting the screws, you probably did not drill the holes deep enough.

5. For Metal Top Benches

It is advisable to use 10-32 flat head bolts (not included) with a length of about 1/2" more than the thickness of your bench top. Use the template below as described above to locate the centers and drill 1/4" holes through the bench top. Bolt the stand down using washers and nuts on the underside. If the bench top is made of sheet metal with a lightweight substrate, we recommend adding a board or metal plate to the underside for extra strength.

6. Adjust the specimen slide

Fig. 4

1) Turn the zoom control knob to the maximum magnification. 2) Turn the diopter adjusting rings to zero. 3) Observe the specimen through the right eyepiece and make the image clear by turning the focusing knob. Fig. 4 5) Rotate the zoom control knob to the minimum magnification. 4) Observe the specimen through the right eyepiece and make the image clear

by turning the right diopter adjusting ring ②. (Fig. 3)

5) Redo steps (1), (3), (4), and (5) until the right adjusting ring is more precise. 6) Do step (4) and make the image clear which is observed through the eyepiece by turning the left diopter adjusting ring ①. (Fig. 4)

NOTE:

1. User could adjust the height distance between the microscope and the work to about 165mm to get a better clear picture. (If it's not clear, adjust the height according to your magnification need.)
2. Install the eye shields for eye comfort.

7. Adjust the interpupillary distance

Adjust the prism housing along the direction of the arrowhead of Fig. 5 until the observation is comfortable.

CLEAN AND CARE RULES

1. After using the microscope, put on a dust cover.
2. Check the setting screws regularly.
3. Keep the environment around the microscope free from moisture, dust and ventilation.

STANDARD BLOCK BALL VISE USER MANUAL

Vise Jaw Thread Replacement · DZQ-627 & DZQ-628

Over tightening the jaws will cause wear and damage to the threads. If jaws become loose, replace with kit DZQ-627. Remove the jaws by opening them wide as possible until they come off the end of the jaw screw (FIG.1) The thread pin is located on the under side of each jaw. NOTE: Before removing locate the one with the "L" This is the left hand thread pin and will need to be replaced with the same. Apply a small amount of grease (included in kit) to the O-rings screw before installing them. Lift the jaw screw out of the yoke that it rotates and replace it. Note which side the left hand thread is on. Grease the thread yoke well.

Now, the hard part: you must start the jaws threads at the same time when replacing them (FIG. 2). Hold each jaw in position and turn the jaw screw to close them. Either a large rubber band or a second person is useful to help the jaw screw while you hold the jaws against the thread. If the jaws don't meet at the same time in the center, remove them and try starting the threads at the same time again.

Rotational Lock Replacement

The LOCK or DRAG PIN is subject to much wear and may need to be replaced after extended use. Simply remove the ball swivel tension screw with the hex

wrench. The spring and Lock Pin should follow (FIG. 3) if not, turn the ball they fall out. Replace the Lock Pin (DZQ-046), Spring, and Tension Screw.

Turntable Base For Microscope Work · DZQ-616-V2

To use the Turntable Base, lock the vise by tightening the swivel tension screw until the ball will not turn. The turntable now becomes your rotation, allowing to adjust the work's center of rotation into the field of view of the microscope the center of the turntable with the center of the microscope view (FIG. 4). Change working views by repositioning the vise.

Thread Pin Replacement Kit · DZQ-627

(Not Shown). Includes Jaw Screw, Left and Right Thread Pins, O-Rings, and Grease.

INSTRUCTION

With a variety of pins that fit the upper jaw plates of every block, users can instantly solve work holding problems and start working sooner. Includes 8 snap pins, 4 flat square pins, 2 rectangular inset-curve pins, 4 thick round inset pins, rubber-coated pins, and 2 leather-faced ring clamp pins in a molded base.

Ring clamp assembly

The leather helps to protect the items to keep them from getting damaged, such as gold, etc. (USE THESE PADS FOR WHATEVER YOU DON'T WANT TO SCRATCH OR DAMAGE)

Long & Short Pins

These pins also have little rubber pieces on them which will also help protect the work. The long pins are to protect thicker pieces.

8 Little Pins

These pins help to hold something that is kind of a weird shape, or not a typical square or circle. Place them in multiple spots throughout these plates.

Pin Plates

These pin plates have little divots in them for circular and square pieces, making them perfect for coins or rings or any smaller circular items.

Small Plates

These plates have divots in them right along the edge and also have straight edges. Work on the straight side or use the side with the divots to kind of catch the piece.

Round Radius Pins

This one is a good option for work on cylindrical things, like a pen or a scribe. If everything is small, round, and cylindrical, these are a good option.
