4.4 Pre-Operation Checks

• Check engine oil level.
• Check fuel level.
• Inspect digging chain for wear or damage and ensure proper tension.
• Verify all controls (throttle, depth control, stop switch) operate freely.
• Ensure all guards and shields are in place and secure.

5. Operating Instructions

5.1 Starting the Engine

1. Ensure the trencher is on a level surface.
2. Turn the fuel valve to the 'ON' position.
3. If the engine is cold, apply choke.
4. Turn the engine switch to the 'ON' position.
5. Insert the key into the ignition and turn it to the 'START' position. Release the key once the engine starts.
6. Once the engine warms up, gradually push the choke lever to the 'OFF' position.

5.2 Adjusting Trench Depth

Use the Deep Control lever to adjust the digging depth. The trencher can achieve a maximum trench depth of 24 inches. Adjust the depth gradually to prevent overloading the engine.

5.3 Trenching Operation

• Position the trencher at the starting point of your desired trench.
• Engage the digging chain.
• Slowly lower the digging chain into the ground using the depth control. Do not attempt to dig to full depth in a single pass, especially in hard soil. Make multiple passes, increasing depth with each pass.
• Maintain a steady, slow forward speed. The trencher should pull itself forward. Do not force it.
• Utilize the anti-forward safety lock to prevent unintended movement.

• Spark Plug: Inspect and clean the spark plug annually. Replace if electrodes are worn or fouled.

6.2 Digging Chain Maintenance

• Lubrication: Lubricate the digging chain regularly with appropriate chain lubricant.
• Tension: Check chain tension before each use. Adjust as necessary to prevent excessive slack.
• Teeth Inspection: Inspect carbide alloy teeth for wear or damage. Replace worn or broken teeth promptly to maintain digging efficiency.
