Basic Sharpening Procedure
1.  Put on your protective gear and make sure the immediate 
area is clear of bystanders.
2.  Insert the battery into the battery compartment on the 
back of the machine, until it clicks into position. Press the 
On/O switch on the ON (I) side to turn on the machine  
(Fig. 14). 
3.  Hold the upper handle and slowly lower the motor head 
assembly (Fig. 15). If the setting is still o, turn o the unit 
and remove the battery before making adjustments. 
4.  It's normal that during the operation there will be a slight 
amount of sparks. Lift the motor head assembly often and 
examine the tooth. If there's a full curve of the tooth with a 
shiny metal nish, the tooth is well sharpened. 
  Note: A good grind occurs when the contact between the 
wheel and the teeth are gradual and smooth. Do not keep 
the grinding wheel in contact with one tooth for too long. 
5.  After sharpening one tooth, turn o the machine by 
pressing the OFF(O) side of the On/O switch. Lift up the 
motor head assembly. Flip the chain guide lock to the 
unlock position and move the chain so that the next chain 
tooth comes before the chain stop. Flip the chain guide 
lock to the lock position and continue to sharpen the next 
tooth. Repeat this process until you have sharpened all the 
teeth on the same side (Fig. 16). 
6.  After you nished sharpening all of the teeth on one side, 
turn o the machine and remove the battery. Loosen the 
swivel angle adjusting knob and reset the swivel angle to 
the same angle on the other side (e.g. if you use 20° on 
right as the swivel angle for one side, set it to 20° on left 
for the other side) (Fig. 17).
