11. Operation.

Always cut high grass from the top and down. This will prevent grass from getting twisted
around the drive shaft and trimmer head, which can cause overheating and damage. If
grass or the like does get twisted around the drive shaft, STOP engine, detach spark plug
lead and remove.
Trimmer
The cord is advanced by tapping the cord housing lightly on the ground while the motor is
running at full speed.
Hold trimmer at an angle towards the area to be cut.
Figure 12 shows the best cutting zone. Always work from left to right.
Use cord to cut. Do not force cord housing into uncut grass. Wire and fences cause
accelerated wear and can break cord. Stones and bricks, curbstones and wood cause very
rapid cord wear. Work around trees and bushes. Bark and wooden ornaments, wood
cladding and posts can be damaged by the cord.
Brushcutter
Figure 13 shows the best cutting zone. Always work from right to left.
