Operating the Grass Trimmer

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.
