This document is an assembly instruction manual for the fischertechnik STEM Pneumatics kit, which allows users to build and experiment with various pneumatic models. The kit is designed to introduce concepts in Science, Technology, Engineering, and Mathematics (STEM) through hands-on construction and experimentation. It includes components for building 8 different models, ranging from basic functional models to more complex project models.

Function Description:

The fischertechnik STEM Pneumatics kit enables the construction of models that demonstrate the principles of pneumatics, which involves the use of compressed air to generate mechanical motion. The core components of the kit include air pumps, cylinders (single and double-acting), valves (e.g., 3/2-way magnetic valve), pressure gauges, air reservoirs, and tubing. These components are assembled onto a base plate using fischertechnik's interlocking building system.

The models illustrate how compressed air can be used to:

Generate linear motion: Cylinders extend and retract based on air pressure, as seen in barrier models.
Create rotary motion: Compressed air motors convert air pressure into rotational movement.
Perform gripping actions: Vacuum grippers use negative pressure to pick up objects.
Lift and lower objects: Scissors lift platforms demonstrate how pneumatic cylinders can be used in lifting mechanisms.

The manual provides step-by-step instructions for building each model, along with detailed diagrams for component placement and tubing connections. Electrical diagrams are also included for models that incorporate electronic components like the 3/2-way magnetic valve, which requires a 9-12V DC power supply.

Important Technical Specifications:

Power Supply: The kit is designed to be powered by either a fischertechnik 9V battery holder (Art. No.: 135719) or an 8.4V Accu Pack (Art. No.: 35537). It explicitly states that 9V NiMH accu packs should not be used with this product.
Electrical Components: The 3/2-way magnetic valve operates on 9-12V DC with a current draw of 130 mA. All electrical components (motors, lamps) must only be connected to fischertechnik power supplies.
Pneumatic Components: Includes single-acting and double-acting cylinders, a pressure gauge (range -0.5 to 2.5 bar), air hoses of various lengths (5 cm, 10 cm, 15 cm, 20 cm, 25 cm, 45 cm), and an air reservoir.
Building System: Utilizes the fischertechnik interlocking grid plate system and various structural components.
Number of Models: 8 distinct models can be built, including:
- Functional Model
- Extended Functional Model
- Barrier with Single Acting Cylinder
- Barrier with Double Acting Cylinder
- Vacuum Gripper
- Compressed Air Motor
- Scissors Lift Platform
- Project Model

Usage Features:

Educational Focus: The kit is intended for educational purposes, providing hands-on learning experiences in pneumatics, mechanics, and basic electronics. It aligns with STEM principles.
Multi-language Support: The manual includes instructions in German, English, French, Dutch, Spanish, Portuguese, Italian, Russian, and Chinese, making it accessible to a broad international audience.
Detailed Assembly Instructions: Each model features clear, numbered steps with visual diagrams, making the construction process straightforward.
Schematic Diagrams: Air line layout plans and circuit diagrams are provided for understanding the pneumatic and electrical connections.
eLearning Portal: fischertechnik offers an eLearning portal (www.fischertechnik-elearning.com) with additional background knowledge and didactic materials for classroom use, enhancing the learning experience.

Maintenance Features:

Component Care: The manual emphasizes that all individual components, especially moving parts, should be maintained and cleaned as necessary to ensure proper functioning and longevity of the models.
Battery Safety: Strict safety guidelines are provided for battery usage:
- Non-rechargeable batteries must not be charged.
- Rechargeable batteries should only be charged by adults and must be removed from the battery holder before charging.
- Batteries must be inserted with correct polarity.
- Dead batteries should be removed from the toy and disposed of at a special waste disposal center.
- Connecting terminals must not be short-circuited.
- Wires should not be inserted into electrical outlets.
Charger Inspection: The battery charger should be regularly inspected for damage. A damaged charger must not be used until fully repaired.
Environmental Protection: The manual includes notes on environmental protection, encouraging responsible disposal and care for the product.
