MAINTENANCE

How to maintain your brushcutter?

Tall grass, brambles, banks, edges: thorough maintenance improves the cut, prevents the gearhead from overheating and extends the life of wear parts (line, blades, filters, spark plug).

WHY MAINTAIN IT?

A CLEAN CUT & A DURABLE MACHINE

At high speed, deposits on the housing, a clogged filter, a worn spark plug or a dull blade cause power loss, overheating and gear wear. Regular maintenance ensures easy starting.

SAFETY & PPE

	Engine off, stable ground. Petrol: suppressor cap disconnected. Electric: battery removed / cord unplugged.
	PPE: goggles/face shield, gloves, ear defenders, non-slip footwear.

NYLON LINE OR BLADE?

Line head

SOFT GRASS

Finishing work. Lines ø 1.6–3.0 mm; round = quiet, twisted = clean, square = aggressive.

Blade

BRAMBLES / DENSE

3-4 teeth, flat knife or saw blade. Durable, but extra caution required (kickback).

ROUTINE AFTER USE

1	Clean the housing Non-metal scraper for grass and mud.
2	Rinse gently While protecting the engine / electrical parts, then dry.
3	Protect A light coat of penetrating spray on the blade and metal parts.

KEY MAINTENANCE POINTS

Nylon line

Store it supple (damp); wind it taut, in even layers.

Air filter

Brush/blow it clean or use soapy water; replace ~every 2 years.

Spark plug

Clean the electrodes, check the gap; replace if worn.

Fuel mix

2-stroke mix per the manual (e.g. 1:50); fresh fuel.

Gearhead

Specific grease; watch for overheating, noise or play.

Blades

Sharpen to the original angle; replace if warped / rusted.

ERGONOMICS

HARNESS & ANTI-VIBRATION

Adjust the harness to spread the load (shoulders, wrists); set the handlebar angle to work flat. Anti-vibration mounts in good condition reduce fatigue and protect the drive.

WINTER STORAGE

EMPTY THE CIRCUIT

Empty the tank and line, then run the engine until it stalls. Grease the blade and store the engine upright, in a dry place. Battery: partial charge, frost-free.

SERVICE INTERVAL TABLE

Interval	To do
After ~15 h	Clean the air filter; check and top up the gearhead grease.
Once a year	Clean the spark plug (gap); check hoses/cables/play; sharpen the blade or replace the line.
Every 2 years	Replace the spark plug and the air filter.
Winter storage	Drain the fuel (tank + circuit); apply an anti-corrosion coat.

QUICK DIAGNOSIS

Line breaks often

Dry/unsuitable line, too long an extension, repeated impacts.

Power loss

Clogged filter, worn spark plug, stale fuel, dull blade.

Head/gearhead overheating

Lack of grease, grass under the housing, speed too high.

Abnormal vibration

Warped blade, uneven winding, tired anti-vibration mounts.

MAINTENANCE CHECKLIST

	Safety: suppressor cap / battery disconnected, PPE worn.
	Cleaning: housing cleaned, metal parts protected.
	Filter clean, spark plug OK (gap).
	Gearhead greased, no play/noise.
	Cutting: suitable/hydrated line or sharpened/balanced blade.
	Fresh fuel in season; drained for winter storage.

FREQUENTLY ASKED QUESTIONS

Which line diameter should I choose?

≈ 1.6–2.0 mm for fine grass, 2.4–3.0 mm for dense grass; respect the head's maximum diameter.

Line or blade for brambles?

Prefer a blade (3-4 teeth or flat knife): it transfers energy better on woody vegetation.

Which mix for a 2-stroke?

Follow the manufacturer's manual (often 1:50 / 2%), with fresh fuel.
