5. Käyttöohjeet

5.1 Moottorisahan käynnistäminen

Always start the chainsaw on a flat, stable surface, clear of obstructions. Ensure the chain brake is engaged before starting.

Kylmäkäynnistysmenettely:

1. Kytke ketjujarru päälle.
2. Press the primer bulb 5-7 times until fuel is visible. Do not over-prime.
3. Pull the choke lever to the FULL CHOKE position.
4. Place your right foot through the rear handle and hold the front handle firmly with your left hand.
5. Pull the starter cord with your right hand using short, sharp pulls until the engine briefly fires (usually 1-3 pulls).
6. Push the choke lever to the HALF CHOKE position.
7. Continue pulling the starter cord until the engine starts and runs.
8. Once running, quickly disengage the choke by blipping the throttle. Allow the engine to warm up for a few moments before disengaging the chain brake and beginning work.

Warm Start Procedure:

1. Kytke ketjujarru päälle.
2. If the engine is warm, do not use the choke. If it has cooled slightly, use the half-choke position.
3. Vedä käynnistysnarusta, kunnes moottori käynnistyy.
4. Blipping the throttle will disengage the choke if used.

5.2 Leikkaustekniikat

Always plan your cuts and be aware of falling timber and kickback zones.

• Hakkuu: Requires careful planning of the felling direction, escape routes, and proper notching techniques. Only attempt if properly trained.
• Jäsenyys: Remove branches from a fallen tree. Work from the base towards the top, supporting the log to prevent pinching.
• Kiinnitys: Cutting a fallen log into shorter sections. Be mindful of tension and compression in the wood to avoid pinching the bar.
• Always use the bucking spikes for leverage when possible.
• Maintain full throttle during cutting to ensure proper chain speed and lubrication.
