The parts of the stage are detailed below in Figure 4:
Figure 4: Picture of Swift/Hacker Stage with each part detailed.
- Sample Holder: Slides go in this area. The slide fits into a groove on the vertical and horizontal axis, and secured by the moving lever arm on the left.
- Vertical Motion Control: The wheel and lever can independently control the vertical motion of the slide. The wheel on the right can move the slide both up and down, whereas the lever only moves the slide up.
- Moving Horizontal Scale: Scale bar moves with sample. Tick marks represent 1mm.
- Fixed Horizontal Scale: Scale bar in a fixed location. Tick marks represent 1mm.
- Moving Vertical Scale: Scale bar moves with the sample. Tick marks represent 1mm
- Fixed Vertical Scale: Scale bar in a fixed location. Tick marks represent 1mm
- Screw Hole: Location for screw to mount the unit to the microscope stage.
- Horizontal Motion Control: Locks and releases the horizontal position. Turn counterclockwise to disengage with the gears and release stage to the left. Turn clockwise to engage the gears and can set the location by pulling the stage to the right.
- Front Cover Screws: Six screws holding on the front cover. Take out these screws to remove the front cover and change the gears.
The Digital Counter
The digital counter connects to the stage via a two slot power cable. The counter is detailed below in Figure 5:

1.Screw two locating screws into the locations shown below (Figure 6). For installation onto other microscopes you may need to move the locating screws. The Swift sample holder offers several options for different stages.

3. Take the screw (Figure 8) and screw into the stage (Figure 9).

- Plug the counter into a power source, regulated is preferred.
- Take the two-slot power cable from the digital counter and plug into the stage (Figure 10)

- Place slide in the holder by sliding the sample in the vertical groove (Figure 11).

2. Secure the slide by moving the lever arm in so it holds the slide in place (Figure 12).

1.Turn the knob counterclockwise to release the gears and allow the holder to slide over to the left (Figure 13). The stage will start to move to left on its own and you should be able to move the stage freely right and left, but it will not stick yet.
Figure 13: Knob being turned counterclockwise.
2. Turn the knob clockwise to re-engage the gears. Now the position will not slip to the left anymore and the stage can be pulled to the right to the desired location (Figure 14). A good starting place is to line up the '0' hash mark on the first hash mark of the fixed scale bar, however this will depend on the sample being observed.

...
The position can be set by using either the wheel or the lever, illustrated in Figure 15. The wheel and lever will both move the sample up by 0.2 mm with each click. This step size cannot be altered.

...
Set the position for the first time using the wheel. The wheel allows for faster and larger adjustments. Turn the wheel towards you, counterclockwise, and the holder will move up (Figure 16).
Figure 16: Wheel being turned to move sample up.
To move the holder down or to make larger steps pull the knob at the end of the lever (Figure 17). There is a small pin that typically rests inside a slot. Turn the knob and release so that the pin is outside the slot. The wheel can now be turned freely clockwise or counterclockwise. This is the only way the move the sample down.
Figure 17: Knob being pulled out of the lever. The pin is shown by the red callout.
...
The lever is a good way to move the stage in incremented steps while observing the sample. Push down on the lever and then release, the stage will move up in 0.2 mm increments, shown in Figure 18 and Figure 19 below. If the lever does not return all the way, push up on the lever and you will hear the click and observe movement.

Counting Samples
- Turn the power to digital counter on using the power button outlined in red below (Figure 20)
...
The gears and gear locations are specific change between the three and four gear setups. The two options are illustrated below in Figure 21 and Figure 22. The circles represent the gear locations and the letter corresponds to the letter stamped on the gear. Note that in both the three and four gear arrangement there are four letters associated with one location. These are all the possible gears that could go in that location.
Figure 21: Layout of the three gear combination. The location of Gear A and Gear B are called out. Third gear location could be used with gears C,D,G, or H.
Figure 22: Layout of the four gear combination. The location of Gear A, E, and F are called out and fixed. The fourth gear location could be used with gears C, D, G, or H.

- Grab a flathead screwdriver and remove the six screws attaching the front plate to the unit (Figure 2223).

2. Pull up the plate by the center knob (Figure 2324).
Figure 2324: Front plate being lifted off.
3. Now you see the inner workings of the stage (Figure 2425). Gears can be lifted out as desired and replaced with a combination listed above. When reattaching the front plate you may need to move the horizontal bar back and forth to get the plate to engage properly with the gears. Do not remove the wheel with the attached paddle. The wheel is connected to a spring and engages with the solenoid.
