Dry sump lubrication

• Advantages: Keeps oil clean, allows for a larger oil capacity, and provides better cooling.
• Disadvantages: More complex and expensive design.

Splash lubrication

• Advantages: Simple and inexpensive.
• Disadvantages: Not suitable for high-speed or high-load applications, and oil can become contaminated.

3. Explain the principles of hydraulic systems and how they are used in power equipment.

• Pascal’s principle: Pressure applied to a confined fluid is transmitted equally in all directions throughout the fluid.
• Hydraulic systems use this principle to transfer power and motion.
• Components of a hydraulic system: pump, reservoir, valves, hoses, and actuators.
• Applications in power equipment: power steering, brakes, lifting mechanisms, and attachments.

4. Discuss the safety precautions to take when repairing or maintaining power equipment.

• Disconnect the power source.
• Wear appropriate personal protective equipment (PPE) such as gloves, eye protection, and earplugs.
• Inspect the equipment for any damage or defects before operating it.
• Follow the manufacturer’s instructions for maintenance and repair procedures.
• Use proper tools and equipment for the job.
• Do not attempt repairs or maintenance unless you are qualified to do so.

5. Describe the troubleshooting process you would follow to diagnose a problem with a power equipment engine.

• Gather information: Observe the symptoms, check the fuel level and condition, inspect the spark plug, and listen for unusual noises.
• Test and inspect: Perform diagnostic tests on the engine components, such as compression test, spark test, and fuel pressure test.
• Analyze the results: Interpret the test results and identify the likely cause of the problem.
• Repair or replace: Make the necessary repairs or replacements to fix the engine.
• Test and verify: Test the engine after the repair to ensure it is operating properly.

6. Explain the importance of regular maintenance for power equipment and describe the recommended maintenance schedule.

• Regular maintenance prevents breakdowns, extends equipment life, and ensures optimal performance.
• Recommended maintenance schedule:
  • Daily: Check fluid levels, inspect belts and hoses.
  • Weekly: Clean air filters, lubricate moving parts.
  • Monthly: Change oil and filter, inspect spark plugs.
  • Yearly: Comprehensive inspection and servicing by a qualified technician.

7. Discuss the different transmission systems used in power equipment and their applications.

• Manual transmission: The operator manually shifts gears using a clutch and gear lever.
• Automatic transmission: The transmission automatically shifts gears based on engine speed and load.
• Hydrostatic transmission: Uses hydraulic fluid to transfer power from the engine to the wheels, providing smooth and variable speed control.
• CVT transmission: Similar to a hydrostatic transmission, but uses a continuously variable pulley system for even smoother and more efficient power transfer.

8. Describe the techniques used to diagnose and repair electrical problems in power equipment.

• Visual inspection: Check for loose connections, damaged wires, and burnt components.
• Electrical testing: Use a multimeter to check for voltage, continuity, and resistance.
• Circuit tracing: Follow the electrical circuit to identify the source of the problem.
• Component replacement: Replace any faulty components, such as switches, relays, or solenoids.

9. Explain the principles of combustion and how they apply to power equipment engines.

• Combustion: The chemical reaction between a fuel and oxygen, releasing heat and energy.
• In power equipment engines, combustion occurs in the cylinder.
• The fuel is mixed with air and compressed by the piston.
• The spark plug ignites the mixture, causing combustion and expansion of gases.
• The expanding gases drive the piston down, converting the thermal energy into mechanical energy.

10. Describe the principles of hydraulics and how they apply to power equipment systems.

• Hydraulics: The use of pressurized fluid to transmit power and motion.
• In power equipment, hydraulic systems are used for tasks such as lifting, steering, and braking.
• Components of a hydraulic system: pump, reservoir, valves, hoses, and actuators.
• Hydraulic fluid is pumped through the system, creating pressure.
• The pressure is used to actuate hydraulic cylinders or motors, which perform the desired functions.
