• you need extra force to saw in;
• the cut path does not go straight;
• vibration increases;
• fuel consumption increases.

Before filling:
• Make sure the saw chain is held securely.
• Make sure the engine is stopped.
• Use a round file of proper size for the chain (see "Chain maintenance table").

tie-strap breakage.
Place the file on the cutter and push straight forward.
Keep the file position as illustrated.
