Ryobi RY40800 Operator's Manual page 58

WARNING:
Never use a left-handed (cross-handed) grip,
or any stance which would place your body or
arm across the chain line.
 Maintain a proper grip on the saw whenever
the unit is running. The fingers should encircle
the handle and the thumb is wrapped under the
handlebar. This grip is least likely to be broken
(by a kickback or other sudden reaction of the
saw). Any grip in which the thumb and fingers
are on the same side of the handle, is danger-
ous because a slight kick of the saw can cause
loss of control.
WARNING:
Do not operate the switch trigger with your left
hand and hold the front handle with your right
hand. Never allow any part of your body to be
in the chain line while operating a saw.
PROPER CUTTING STANCE
See Figures 12 - 13.
WARNING:
Always use the proper cutting stance described
in this section. Never kneel when using the
chain saw, except when felling a tree as illus-
trated in Figure 13. Kneeling could result in loss
of stability and control of the chain saw, result-
ing in serious personal injury.
 Weight should be balanced with both feet on
solid ground.
 Keep left arm with elbow locked in a "straight
arm" position to withstand any kickback force.
 Your body should always be to the left of the
chain line.
 Thumb should be on underside of handlebar.
BASIC CUTTING PROCEDURE
Practice cutting a few small logs using the following
technique to get the "feel" of using the saw before
you begin a major sawing operation.
