kickback and maintain control of the saw.
Keep the fingers of your left hand encir-
cling and your left thumb under the front
handlebar. Keep your right hand com-
pletely around the rear handle whether
your are right handed or left handed. Keep
your left arm straight with the elbow
locked,
• Position your left hand on the front handle-
bar so it is in a straight line with your right
hand on the rear handle when making
bucking cuts. Never reverse right and left
hand positions for any type of cutting,

both feet,

keep your body from being in a direct line
with the cutting chain,

thrown off balance and lose control of the
