- -7 to + 35 °C: Synthetic oils 10W-30 or 15W-40 (Multi-viscosity)
Usage Features:
- Cleanest Emissions in Class: Certified 53% cleaner emissions than comparable engines, meeting EPA standards. It features standard low-tone catalytic mufflers that reduce carbon monoxide emissions below OSHA permissible exposure limits.
- SAM Safe Air Monitor: Enhances safety by alerting operators to unsafe carbon monoxide levels and automatically shutting down the engine to prevent injury.
- Reliability: Utilizes LEHR Propane Fuel Systems with a patented variable venturi and fuel jet design that requires no field adjustments and never comes out of calibration. A three-stage pressure regulator vaporizes liquid propane, making the LX700 safe and reliable.
- Propane Durability: Designed with heavy-duty piston rings, a cast iron cylinder liner, and hardened heads to resist wear and ensure precise timing, contributing to a long engine life. The heavy-duty, low-tone catalytic muffler is supported by two brackets to the engine block, designed to last the life of the engine.
- Throttle Control: Features a throttle trigger with "CHOKE" for cold starts, "FAST" for maximum revs during operation, and "SLOW" for minimum revs.
- Environmental Considerations: Designed for optimal performance across various temperatures and altitudes. Users are advised to adjust oil type based on operating temperature and be aware of power reduction at higher altitudes.
- Safety Warnings: Emphasizes reading and understanding the manual, avoiding loose clothing near moving parts, allowing the engine to cool before refueling, and never operating in enclosed areas due to carbon monoxide emissions. Propane is flammable, requiring careful handling and storage.
Maintenance Features:
- Regular Maintenance Schedule: A detailed schedule is provided for checking oil level, cleaning air inlet screen, changing oil, cleaning silencer and engine, checking and clearing air filter, checking and replacing spark plug, checking fuel filter, and replacing air cleaner elements.
- Oil Change: Recommended to drain oil when the engine is warm. The oil capacity is approximately 2.0 Liters.
- Air Filter Maintenance: The air filter is crucial for engine efficiency and life. It should be kept free of debris and in perfect working order. Cleaning involves using compressed air to remove dust and debris from the primary and secondary elements, without using water, petrol, or detergents.
- Spark Plug Service: Involves removing, cleaning, and checking the gap (0.6-0.8mm) between electrodes. Replacement is necessary if electrodes are burnt or porcelain is damaged.
- Fuel System Maintenance: Propane fuel should be drained thoroughly if the engine is not used for more than one month to prevent deterioration and gum deposits, which can cause hard starting and clog the fuel system.
- Cleaning and Storage: The engine exterior should be cleaned with compressed air (max. 6 bars) to prevent debris and dust from entering. Storage should be in a dry, ventilated place, sheltered from severe weather, with the engine cooled down and the fuel tank empty.
- Troubleshooting Guide: Includes a table for common problems (hard starting, inconsistent working, loss of power) with their reasons and corresponding solutions, such as checking fuel, cleaning components, or contacting a licensed service center.
- Parts Ordering and Support: Instructions for ordering replacement parts via the ONYX website (www.onyxsolutions.com) and submitting help tickets for technical support (https://onyxsolutions.odoo.com/contact). Warranty claims information is also available on the support page (https://www.onyxsolutions.store/support).
- Environmental Protection: Emphasizes proper disposal of old machine components, packaging material, batteries, and toxic liquids (like anti-freezing agent and oil) according to local regulations, ensuring environmental safety and encouraging recycling.
