Jonsered CS2258 Li Operator's Manual page 8

• Always keep correct footing and operate the product
only on safe and level surfaces. Slippery or not
stable surfaces, such as ladders, can cause a loss of
balance or control.
• The first-time user should cut logs on a saw-horse or
cradle as basic practice.
Kickbacks, skating, bouncing and
dropping
Different forces can have an effect on the safe control of
the product.
• Skating is when the guide bar moves quickly across
the wood.
• Bouncing is when the guide bar lifts off the wood and
touches it again and again.
• Dropping is when the product drops down after the
cut is made. This can cause the moving chain to
touch a part of the body or other objects, causing
injury or damage.
• Kickback is when the end of the guide bar touches
objects and moves rearward, up or suddenly
forward. Kickback also occurs when the wood closes
in and pinches the saw chain during the cut. Loss of
control can result if the product touches an object in
wood.

• Rotational Kickback can occur when the moving
chain touches an object at the top of the guide
bar. This can cause the chain to bury into the
object and cause the chain to stop immediately.
The result is a very fast, reverse reaction that
moves the guide bar up and rearward in the
direction of the operator.
• Pinch-Kickback can occur when the saw chain
suddenly stops during the cut. The wood closes
in and pinches the moving saw chain along the
top of the guide bar. The sudden stop of the
chain reverses the chain force and causes the
product to move in the opposite direction of the
turn of the chain. The product moves rearward in
the direction of the operator.
• Pull-In can occur when the saw chain suddenly
stops when the moving chain touches an object
in the wood along the bottom of the guide bar.
The sudden stop pulls the product forward and
away from the operator, which can easily cause
the loss of control of the product by the operator.
