Maintenance Schedule

Regular maintenance prevents major repairs. Follow intervals based on operating hours.

1. Daily/Before Use: Check for loose fasteners, leaks, damage. Clean air intake.
2. Every 25 Hours: Clean/check spark plug (gap 0.5mm). Check fuel filter.
3. Every 50 Hours: Clean air filter (replace if damaged). Check clutch drum bearing.
4. Every 100 Hours: Replace fuel filter. Check carburetor diaphragm. Inspect drive shaft.
5. Seasonal/Storage: Drain fuel or add stabilizer. Clean entire unit. Grease gear head.

WARNING! Never operate unit with damaged or missing safety components.

Engine Repair (Cylinder, Piston, Crankshaft)

Major engine disassembly requires special tools (puller, ring compressor).

1. Remove top cover, air filter, and muffler.
2. Remove cylinder cover and decompression valve assembly.
3. Unbolt and carefully lift off cylinder. Inspine for scoring.
4. Remove piston pin circlips, push out pin, remove piston. Check rings for wear.
5. To remove crankshaft: Support crankcase, use puller to separate halves (if required).
6. Reassembly: Lubricate all parts with 2-stroke oil. Ensure ring end gaps are correctly positioned.
7. Torque cylinder bolts to specified value (typically 10 Nm) in criss-cross pattern.

Note: Replace gaskets and seals during reassembly.

Fuel System (Carburetor, Tank, Filters)

Common issues: hard starting, poor idle, loss of power.

1. Drain fuel tank completely.
2. Remove carburetor cover and air filter housing.
3. Disconnect fuel lines and throttle linkage. Remove carburetor (Zama C1Q-S267 common).
4. Disassemble carb: Remove diaphragms (pump and metering), check for stiffness/holes. Clean jets with compressed air.
5. Fuel Tank: Remove and clean sediment. Replace fuel filter and fuel line if cracked.
6. Reassemble with new diaphragm/gasket kit. Adjust idle and high-speed screws to factory settings as starting point.

Tip: Use STIHL pressure/vacuum tester to check carburetor function.

Ignition System (Spark Plug, Coil, Switch)

No-spark condition troubleshooting.

1. Spark Plug: Remove, check gap (0.5mm), clean or replace (STIHL part # 0000 400 1300).
2. Ignition Coil: Check air gap between coil legs and flywheel (0.2-0.4mm). Use feeler gauge.
3. Stop Switch: Disconnect wire from coil. If spark returns, switch is faulty.
4. Flywheel: Check for sheared key if timing is off. Use puller to remove.
5. Testing Coil: Use ohmmeter per manual specifications for primary/secondary windings.

CAUTION! Never crank engine with spark plug removed and boot unattached – risk of ignition coil damage.

Drive Shaft & Gear Head

For vibration, noise, or loss of drive.

1. Remove cutting attachment and clutch drum.
2. Detach drive shaft housing from engine unit.
3. Inspect flexible drive shaft for kinks or wear. Replace if damaged.
4. Gear Head: Remove cover, clean old grease, inspect spiral bevel gears for pitting.
5. Repack with STIHL gear grease (part # 0781 400 0801). Reassemble, ensuring proper gear mesh.
6. Check bearing in clutch drum for smooth rotation; replace if rough.

Anti-Vibration System

Reduces operator fatigue. Check if handles have excessive play.

System consists of rubber dampers at engine mounts and handle connections.

1. Inspect all rubber isolators for cracks, tears, or disintegration.
2. Replace by unbolting handle assembly or engine mounting points.
3. Ensure all bolts are tightened to specified torque after replacement.

Starter Assembly (ErgoStart)

Repair for rope not retracting or starter slipping.

1. Remove starter cover screws. Carefully release spring tension.
2. Inspect starter pulley and pawls for wear. Replace if damaged.
3. Rewind spring or replace entire starter assembly (part # 0000 400 1307).
4. Check decompression valve on cylinder head; clean or replace if clogged.

Clutch & Throttle Cable

Clutch engages at ~2800 rpm. Symptoms: tool spins at idle or doesn't engage.

1. Remove clutch cover and clutch drum.
2. Use clutch holding tool to prevent rotation. Remove clutch nut (left-hand thread).
3. Inspect clutch shoes for wear and springs for fatigue. Replace as a set.
4. Throttle Cable: Adjust at carburetor lever for proper free play and full opening.

Troubleshooting Guide

Final Check: After any repair, reassemble completely, check all fasteners, and test run unit without load before use.
