Frequently Asked Questions - FX-KSP351 Fuxtec
What type of fuel should I use for the FX-KSP351 chainsaw?
Use a mixture of unleaded gasoline SP98 (minimum octane rating 95 RON) and 2-stroke oil in a ratio of 40:1. For best performance, use FUXTEC 'Made in Germany' 2-stroke oil.
How do I start the chainsaw when cold?
Activate the chain brake, set the stop switch to 'I', pull the choke to the stop, place the chainsaw on the ground and secure it. Pull the starter handle until you hear a cough, then push the choke back and pull again until it starts.
How do I adjust the chain lubrication?
The adjustment screw is located under the chainsaw. Use the provided screwdriver: turn in the '+' direction to increase oil flow, in the '-' direction to decrease it. Check the oil trace on a light background after acceleration.
What should I do if the chain does not stop at idle?
This indicates an issue with the idle speed or clutch adjustment. Turn off the machine and consult the manual for adjusting the idle speed (3,000 ± 500 rpm). If the problem persists, contact an authorized service center.
How do I maintain the air filter?
After each use, unscrew the filter cover, remove the filter and separate its two parts. Blow with compressed air, check the rubber gasket and reassemble. A clean filter ensures better performance.
When should I sharpen the chain?
Sharpen the chain when the sawdust becomes powdery, you need to force the cut, the cut is not straight, or vibrations increase. Use a suitable round file with a guide to maintain the sharpening angles (25°-35°).
How do I check the chain brake function?
Turn off the engine, manually activate the brake by pushing the front hand guard. Try to turn the chain by pressing the tip of the guide bar against wood: if it is blocked, the brake is working. Otherwise, have it repaired immediately.
What protective equipment should I wear?
Always wear a helmet, safety glasses, hearing protection, cut-resistant gloves, non-slip safety boots, and close-fitting clothing. Never work without these protections.
How do I store the chainsaw long-term?
Empty the fuel and oil tanks. Clean the machine, install the guide bar cover, activate the chain brake, and store it in a dry, frost-free place (10-25°C).
Avoid contact with chemicals.
Avoid contact with chemicals.
What is the procedure in case of kickback?
In case of kickback, the chainsaw may be thrown towards the operator. To avoid it, always hold the machine with both hands, do not saw above shoulder height, avoid contact of the guide bar tip with obstacles, and keep the chain properly sharpened. The automatic chain brake engages in case of violent kickback.
