Safety First

Personal Protective Equipment (PPE) is mandatory. Always operate the chainsaw with extreme caution.

Safety Gear	Purpose
Protective Helmet with Visor & Ear Defenders	Protects head, eyes, and hearing from debris and noise
Chainsaw Protection Trousers	Protects legs from accidental contact with the chain
Protective Gloves	Improves grip and protects hands
Steel-Toe Boots	Protects feet from falling objects and the chain
High-Visibility Clothing	Makes the operator visible to others

WARNING! Never operate a chainsaw when tired, under the influence, or in poor weather conditions. Keep bystanders at a safe distance.

Parts Identification

Key components of your Husqvarna chainsaw.

Front Hand Guard / Chain Brake: Safety feature to stop the chain.
Throttle Trigger: Controls engine speed.
Throttle Trigger Lockout: Prevents accidental throttle engagement.
Rear Handle: Main grip for the right hand.
Start/Stop Switch: Turns the ignition on and off.
Choke/Start Control: For cold starting.
Fuel Tank Cap: Access point for fuel mixture.
Chain Oil Tank Cap: Access point for bar and chain oil.
Guide Bar: Supports and guides the cutting chain.
Chain: The cutting component with sharp cutters.

Assembly & Preparation

Assembling your chainsaw from the box.

Attach the Guide Bar and Chain: Place bar on mounting studs, fit chain around sprocket and bar groove, tension correctly.
Fill Fuel Tank: Use correct petrol/oil mixture (see specifications).
Fill Chain Oil Tank: Use recommended bar and chain oil.
Check Chain Tension: Chain should be snug against the bar but pull freely.

CAUTION! Ensure the chain brake is engaged (pulled forward) during assembly. Always wear gloves.

Starting & Stopping

Cold Start: Engage chain brake. Set choke to full. Press decompression valve (if equipped). Pull starter cord until engine fires. Move choke to half-throttle. Pull again to start. Blip throttle to disengage choke.
Warm Start: Engage chain brake. Set choke to off/half. Pull starter cord.
Stopping: Release throttle. Press the Start/Stop switch to "0" or "Stop".

WARNING! Always start the saw on the ground, firmly holding the rear handle with your foot in the front handle.

Operating Instructions

Proper cutting techniques for safety and efficiency.

Basic Cuts: Use full throttle at the point of cut. Let the chain do the work; do not force it. Be aware of kickback zone (upper quadrant of bar tip).

Felling a Tree: Plan escape path. Make notch cut. Make felling cut. Use wedges if needed.

Limbing & Bucking: Stand on left side of trunk. Cut from top down. Support logs properly when bucking.

Maintenance Schedule

Daily and periodic maintenance tasks.

Task	Frequency	Details
Check Chain Tension	Before each use, when warm	Adjust as needed
Check Chain Sharpness	Before each use	Sharpen if dull
Clean Air Filter	Daily (in dusty conditions)	Tap clean or wash
Check Bar & Chain Oil Flow	Before each use	Adjust oiler if needed
Clean Cooling Fins	Weekly	Remove sawdust buildup
Spark Plug Inspection	Every 50 hours	Clean or replace
Fuel Filter Replacement	Every 100 hours or yearly	Replace in-tank filter

Chain Sharpening & Tensioning

Proper chain maintenance is critical for performance and safety.

Tensioning: Loosen bar nuts. Use tensioning screw to raise bar until chain is snug. Tighten bar nuts. Re-check tension when chain is warm.
Sharpening: Use correct round file size. Maintain correct filing angle (typically 30°). File all cutters to equal length. File depth gauges (rakers) with a flat file and gauge.

Tip: A sharp chain cuts faster, reduces operator fatigue, and is safer than a dull one.

Fuel & Lubrication

Use only high-quality fuels and lubricants.

Fuel Mix: Use unleaded petrol (min. 90 octane) mixed with a high-quality 2-stroke oil. Standard ratio: 50:1 (check manual for your model). Shake well before refueling.
Bar & Chain Oil: Use specially formulated chainsaw oil for proper adhesion. Check flow before each use.

WARNING! Never use straight petrol or automotive motor oil. Never refuel a hot saw. Clean area around fuel cap first.

Storage

Preparing your chainsaw for long-term storage.

Drain all fuel from the tank and run the engine until it stops to clear the carburetor.
Remove, clean, and oil the chain. Store separately.
Clean the entire saw thoroughly.
Store in a dry, secure place, out of reach of children.

CAUTION! Old fuel can gum up the carburetor. Always use the drain procedure.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine will not start	No spark, flooded, old fuel, clogged filter	Check spark plug, use fresh fuel, clean air filter, avoid over-choking.
Engine starts then dies	Fuel line, filter, carburetor issues	Check fuel flow, replace filter, clean carburetor screen.
Chain does not turn	Chain brake engaged, clutch worn, sprocket	Disengage brake, inspect clutch and drive sprocket.
Excessive vibration	Loose parts, unbalanced chain, damaged bar	Tighten all fasteners, balance chain, inspect/replace bar.
Chain throws oil but doesn't lubricate bar	Oil channel blocked, wrong oil, pump fault	Clean oil holes in bar, use correct oil, check oil pump.
Poor cutting performance	Dull chain, low chain tension, worn bar	Sharpen chain, adjust tension, inspect bar rails and groove.
