Cutting Equipment: Clearing blades (for wood), grass blades (for brush cutting), and trimmer heads (for grass trimming) with trimmer cord. Only non-metallic, flexible cutting elements are recommended for trimmer heads.

Usage Features:

Safety Equipment: Includes a throttle trigger lock to prevent accidental engagement, a stop switch for immediate engine shutdown, and a cutting attachment guard to protect the operator from thrown objects and unintentional contact.
Anti-Vibration System: Designed to reduce vibrations for comfortable use. Incorrectly wound cord or blunt cutting equipment can increase vibration levels.
Quick-Release Harness: A quick-release catch on the chest allows the operator to quickly free themselves from the machine and harness in emergencies.
Harness Adjustment: The harness can be adjusted to distribute weight evenly across the shoulders and position the cutting attachment parallel to the ground for optimal working posture.
Cutting Techniques:
- Grass Blade: Used for high or thick grass with a sideways, swinging movement. The blade should work on the left-hand side (between 8 and 12 o'clock) to collect grass in a line.
- Trimmer Head/Plastic Knives: Ideal for cutting grass in difficult-to-reach areas and along borders. The cord should be held parallel to the ground. Reducing cord length and engine speed can prevent damage to plants.
- Sweeping: The rotating cord's fanning effect can be used for quick cleaning by moving the trimmer from side to side at full throttle.
Fuel Handling: Requires careful mixing of petrol and two-stroke oil. Fuelling should be done in a well-ventilated area, away from heat sources, and only when the engine is stopped and cooled.
Starting Procedure: Involves setting the stop switch to start, choke control to choke (for cold engine), priming with fuel, and pulling the starter cord. For warm engines, the choke is not used.
Stopping Procedure: Move the stop switch to the STOP position.

Maintenance Features:

Daily Maintenance:
- Clean the machine's exterior.
- Check the harness for damage.
- Verify throttle trigger lock and throttle function.
- Check stop switch function.
- Ensure the cutting head does not rotate at idle.
- Clean or replace the air filter.
- Inspect guards for damage.
- Check blade for centering, sharpness, and cracks.
- Inspect trimmer head for damage.
- Verify locking nut tightness.
- Check transport guard integrity.
- Tighten all nuts and screws.
Weekly Maintenance:
- Check starter, starter cord, and return spring.
- Inspect vibration damping elements.
- Clean the spark plug and check the electrode gap (0.6-0.7 mm).
- Clean cooling fins on the flywheel.
- Clean or replace the muffler's spark arrestor screen (if fitted).
- Clean the carburettor area.
- Clean cylinder cooling fins and check air intake.
- Check and fill angle gear with special grease (3/4 full).
Monthly Maintenance:
- Clean the fuel tank with petrol.
- Clean the carburettor and surrounding area.
- Clean the fan and surrounding area.
- Check and replace fuel filter and fuel pipe if necessary.
- Check all cables and connections.
- Check clutch, clutch springs, and clutch drum for wear.
- Change the spark plug.
Carburettor Adjustment: The idle speed (T-screw) can be adjusted to ensure the trimmer head does not rotate at idle. Professional adjustment by an authorized dealer is recommended after 8-10 tanks of fuel for optimal performance and reduced emissions.
Muffler Maintenance: Regular cleaning of the spark arrest screen is crucial to prevent engine overheating. Damaged screens should be replaced.
Air Filter Maintenance: Clean the air filter with warm, soapy water every 25 hours or more frequently in dusty conditions. Replace damaged or old filters.
Angle Gear Maintenance: The angle gear is factory-filled with grease and usually does not require changing unless repaired.
Spark Plug Maintenance: Regularly check and clean the spark plug, ensuring the correct electrode gap. Replace if dirty or after about one month of operation.
Blade Sharpening: Grass blades should be sharpened using a single-cut flat file, ensuring all edges are sharpened equally to maintain balance. Damaged, bent, or cracked blades must be discarded and replaced with original types.
Trimmer Cord Maintenance: Ensure the trimmer cord is wound tightly and evenly to prevent harmful vibrations. The knife on the trimmer guard should be intact to cut the cord to the correct length. Soaking the cord in water can increase its life.
