Step 4 - Extending spool line while trimming

1) While the line spool is running at full speed, tap its underside briefly against the ground.
2) If the spool lines are still not sufficiently extended, tap the underside against the ground again.
3) If the line has already become too short, it will no longer be extended by pressing the
underside against the ground. You must pull it out from the line spool by hand.
4) Switch off the motor.
5) Lay the machine on the ground.
6) Push by hand on the underside of the line spool and pull both lines out until they are
somewhat longer than the edge of the protective bonnet. The lines are trimmed to the correct
length by the line trimming knife.
WARNING! Ensure there is mixed fuel in tank with the correct ratio of fuel to oil. Make sure all
guards and handles are properly and securely attached.
