3. Setup and Assembly
3.1 Unpacking
Carefully remove all components from the packaging. Inspect for any damage that may have occurred during transit. Retain packaging materials for future storage or transport.
3.2 Assembly
The tiller may require some assembly upon arrival. Typically, this involves attaching the handlebars, wheels, and tines. Refer to the detailed diagrams in the separate assembly guide for specific steps. Ensure all bolts and fasteners are securely tightened before operation.

4. Operating Instructions
4.1 Fueling the Engine
The FX815TG uses gasoline as fuel. Fill the fuel tank with unleaded gasoline. Do not overfill. Ensure the fuel cap is securely fastened. The oil tank volume is 600 ml, and SAE 30 engine oil is recommended.
4.2 Starting the Engine
- Ensure the fuel valve is open.
- Set the choke lever to the 'START' position (if cold engine).
- Set the throttle lever to the 'FAST' position.
- Pull the recoil starter handle firmly until the engine starts.
- Once the engine starts, gradually move the choke lever to the 'RUN' position.
4.3 Adjusting Working Width and Depth
The working width can be adjusted from 36 cm to 85 cm by adding or removing tine sections. The working depth of 30 cm is achieved by adjusting the depth bar at the rear of the tiller. Experiment with settings to find the optimal depth for your soil conditions.
4.4 Gear Selection
The tiller features 1 forward gear and 2 reverse gears. Use the appropriate gear for the task at hand. The reverse gears provide enhanced maneuverability in tight spaces. Always ensure the tiller is stationary before changing gears.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your TEXAS FX815TG garden tiller.
5.1 Engine Oil
Check the engine oil level before each use. Add SAE 30 oil if necessary. Change the engine oil after the first 5 hours of operation, and then every 25 hours or annually, whichever comes first.
5.2 Air Filter
Clean the air filter regularly, especially when operating in dusty conditions. A clogged air filter can reduce engine performance and increase fuel consumption.
5.3 Spark Plug
Inspect the spark plug annually or every 50 hours. Clean or replace if necessary to ensure proper ignition.
5.4 Cleaning and Storage
After each use, clean soil and debris from the tines and housing. Store the tiller in a dry, well-ventilated area, away from direct sunlight and extreme temperatures. If storing for an extended period, drain the fuel tank or use a fuel stabilizer.
