Wear safety glasses to protect your 
eyes.
Observe the following points when 
sharpening:
: The cutting blade must be correctly 
clamped in position and the stop 
must swing back out of the way.
: Bring the motor arm slowly 
downward. Check sharpening 
process. Do not remove too much 
material. If necessary, switch off the 
motor and readjust.
: Sharpen the cutting edges by 
applying the wheel several times – 
do not sharpen in a single pass.
