Safety Precautions Against Kickback And Pushback - Westfalia GM BK 4545 Instruction Manual

 always keep safe stand in order to be able to withstand the
backward motion,
 never cut over shoulder height,
 always cut with full speed,
 do not start cutting with the tip of the guide bar or inserting the
tip of the guide bar into the wood first.
Pushback
While cutting with the top of the guide bar the saw chain may
touch a hard object in the wood. This will pinch the saw chain and
pushback the machine in direction to the operator.
Reduce the risk of sudden strikes by inserting the bumper spikes
into the wood first and then start cutting.

Safety Precautions against Kickback and Pushback

To reduce the risk of injury due to kickback, check the proper
function of the chain brake prior to use the gasoline chain saw.
Always keep the saw chain sharp. This will ensure a high level of
safety against kickback. Removal of any safety devices,
inadequate maintenance or incorrect mounting of the guide bar
and saw chain will increase the safety risk and lead to serious
injuries due to kickback.
For safety reasons do not use any other saw chain or guide bar
types not specified in this manual.
 Kickback is the upward motion of the guide bar (17) that
occurs when the saw chain tip contacts a hard object. Kick-
back is dangerous and can lead to loss of control of the chain
saw.
 When cutting converted timber and thin branches, always use
a safe stand, e. g. a sawhorse. Do not stack timber pieces for
cutting.
 Before cutting logs, secure in position. When working on
sloping ground, make sure to work facing upwards.
