This document describes the Titantec XT-BC508-1, a versatile power tool designed for cutting grass, weeds, and denser vegetation. It functions as both a grass trimmer and a brush cutter, offering flexibility for various landscaping tasks.
Function Description:
The Titantec XT-BC508-1 is a 2-stroke engine-powered tool primarily used for cutting vegetation. It can be equipped with a cutting wire for trimming grass and small weeds, or a metal blade for cutting denser vegetation. The tool is designed for private use and should not be used for any other cutting operations that require the cutting tool to be lifted above the ground. It features a recoil starter for engine ignition, a primer pump for fuel delivery, and a choke lever for cold starts. The throttle trigger and lever control engine speed, while a switch allows for easy power management. A protection shield is included for user safety, and a harness hanger is provided for comfortable operation.

Usage Features:
The XT-BC508-1 is designed for user safety and efficiency. It requires proper assembly of the handle, protection shield, and chosen cutting attachment (blade or trimmer head).
- Assembly: The manual provides detailed instructions for installing the right and left handles, handle bracket, protection shield, cutting blade, and cutting head. It emphasizes wearing protective gloves due to sharp edges during assembly.
- Harness: A harness is provided and its use is mandatory for safe operation. The harness should be worn without twisted bands, with the hanger on the right side. The unit must be securely hooked to the harness, and the harness length adjusted so the cutting head is parallel to the ground for optimal balance and comfort. A quick release mechanism is integrated into the harness for emergencies.
- Fueling: The tool uses a mixture of unleaded gasoline and 2-cycle oil at a ratio of 25:1. Fueling should always be done on bare ground, away from open flames, and with the engine stopped and cooled. The fuel tank should be filled to 80% capacity.
- Starting the Engine:
- Feed fuel into the tank and tighten the cap.
- Place the unit on a flat, firm surface, ensuring the cutting head is off the ground and clear of objects.
- Push the primer pump several times until fuel flows in the return tube.
- Move the choke lever to the closed position for cold starts.
- Set the ignition switch to the "start" position. While pulling the throttle lever, push the throttle set button, then release the throttle to engage the "Start position."
- Pull the starter rope quickly until the engine fires.
- Once the engine fires, move the choke lever to the open position and pull the starter rope again to restart.
- Allow the engine to warm up for several minutes before operation.
- Stopping the Engine: Release the throttle lever, run the engine for half a minute, then shift the ignition switch to the "STOP" position. Avoid stopping the engine by pulling the throttle lever in emergencies.
- Adjusting Idling Speed: An idle speed adjuster is available. If the engine stops frequently at idle, turn the screw clockwise. If the cutting head rotates after releasing the trigger, turn the screw counter-clockwise.
- Trimmer Head Usage: The trimmer head is a semi-auto type, allowing line advancement by lightly tapping it on the ground at full throttle. Each tap advances the line by approximately 1 inch (25.4 mm). The cutting is done by the tip of the line. For best results, avoid crowding the line into the cutting area and allow the unit to trim at its own pace. The unit should be held with the head off the ground, tilted about 20 degrees toward the sweep direction. Sweeping from right to left helps avoid thrown debris.
- Metal Blade Usage: When using metal blades, ensure they are securely fastened, not bent, warped, cracked, broken, or damaged. Always wear thick, sturdy gloves when handling blades.
Maintenance Features:
Regular maintenance is crucial for the tool's performance, longevity, and safety.
- General Inspection: Before and after each use, and after any fall or impact, inspect the tool for loose parts (nuts, bolts, screws), fuel leaks, and damaged components (especially the cutting attachment). Any defaults should be addressed by a qualified service agent.
- Blade Maintenance: Always clean and grind the blade. Check for firm installation and damage before use. For long-term storage, clean the blade surface and apply lubricant to prevent rust.
- Refilling Trimming Line: When the line runs out, reload a new one of 2.4mm (.095in) diameter, up to 4m in length. Align arrow marks on the knob and head body, pull out the old line, insert the new line through eyelets, and extend both ends until their lengths match. Wind the line in the correct direction as indicated on the spool, leaving about 160mm of line exposed.
- Air Filter: Check monthly and clean the filter element in warm, soapy water if clogged. Dry completely before reinstalling. Replace if broken or shrunk.
- Fuel Filter: If the engine runs short of fuel, check the fuel cap and fuel filter for blockage.
- Spark Plug: Periodically clean the spark plug and check the plug gap (0.6-0.7mm). Replace if necessary with the correct type. Tighten to 9.8-11.8 N.m.
- Muffler: Inspect periodically for loose fasteners, damage, or corrosion. Any sign of exhaust leakage requires immediate repair by a service agent to prevent fire hazards.
- Storage: Before long-term storage, empty the fuel tank and run the engine until all fuel in the fuel line and carburetor is used. Store the unit indoors with rust prevention measures.
- Troubleshooting Guide: The manual includes a troubleshooting guide for common issues like starting failure and engine not running properly, with probable causes and actions.
Safety Precautions:
The manual emphasizes numerous safety precautions, including:
- Wearing head, eye, and ear protection, protective gloves, and safety footwear.
- Maintaining a 15-meter safety distance from children, bystanders, and helpers.
- Never using saw blades.
- Being aware of thrown objects and hot surfaces.
- Not working near fire or explosion risks.
- Reading the instruction manual completely before use.
- Ensuring the cutting attachment stops turning when the engine idles.
- Avoiding loose clothing or jewelry that could get caught in moving parts.
- Tying back long hair.
- Not operating the machine while tired, ill, or under the influence of medication, drugs, or alcohol.
- Being aware of kickback risks and avoiding placing hands near rotating accessories.
- Taking breaks during prolonged operation to mitigate vibration-related health issues like Raynaud's phenomenon.
- Never modifying the trimmer or cutter.
- Not inhaling exhaust gases.
