Pneumatic / Hydraulic Jack Set SE-8764A
Notes to the Teacher
Description
The Transparent Devices Hydraulic/Pneumatic Jack Set includes a rugged stand that holds a large
cylinder-and-piston syringe, four smaller syringes, and flexible tubing assemblies with valves and
quick-connect fittings, together with this manual.
Purpose
This set makes possible a number of teacher demonstrations and student experiments involving fluids
and air. These include:
The operation of a pump
The hydraulic/pneumatic jack as a force transformer (simple machine)
The difference in the ability of gases to compress compared to liquids
Force, area, and the concept of pressure
Boyle’s law, using air or other gases
Care and use
Some simple precautions will help ensure that this set provides years of use:
When lifting a load such as a stack of books, center the load, do not lift too heavy a load, and do
not lift the load above the 40 cc mark on the syringe.
If lubrication of the syringes is needed, use only glycerin or silicone oil. Do not use petroleum-
based lubricants, as this will quickly damage the seals.
Use only light finger pressure on the quick-connect fittings. Do not over-tighten.
If lost or damaged, replacement parts are available.
Safety
Please teach and expect safe behavior in your classroom and lab. Safety considerations call for
supervision of students at all times, safety eyewear, no horseplay, and immediate reporting to the
instructor of accidents or breakages, among others.

Setting up the apparatus and observing the action of a pump
Thread the syringe collar (d) rounded-side-up onto the 60 cc main syringe body (c).
rounded side
Now push the 60 cc main syringe body (c) into the jack stand (a) such that the scale of the syringe is
900 to the right of the window of the jack stand. Do NOT seat the syringe collar on the stand yet.

Now find the small T-fitting on the main hose assembly and push it against the tip of the 60 cc main
syringe through the bottom of the jack stand. Then turn the entire 60 cc main syringe clockwise 900
until its scale appears in the jack stand window while pushing upward with your thumb on the small Tfitting. This should lock the T-fitting in place at the end of the syringe. Do not over-tighten. Once the
hose is connected, push down on the syringe collar to seat it on the jack stand.
