pole pruner "live'" and could give the operator an
electric shock.
• Wear eye protection. Further protective
equipment for hearing, head, hands, legs
and feet is recommended. Adequate protective
equipment will reduce personal injury from flying
debris or accidental contact with the saw chain.
• Do not operate a pole pruner in a tree, on a
ladder, from a rooftop, or any unstable support.
Operation of a pole pruner in this manner could
result in serious personal injury.
• Always keep proper footing and operate the pole
pruner only when standing on fixed, secure and
level surface. Slippery or unstable surfaces may
cause a loss of balance or control of the pole pruner.
• When cutting a limb that is under tension, be
alert for spring back. When the tension in the
wood fibres is released, the spring loaded limb may
strike the operator and/or throw the pole pruner out
of control.
• Use extreme caution when cutting brush and
saplings. The slender material may catch the saw
chain and be whipped toward you or pull you off
balance.
• Carry the pole pruner by the front handle with
the pole pruner switched off and away from
your body. When transporting or storing the pole
pruner, always fit the guide bar cover. Proper
handling of the pole pruner will reduce the likelihood
of accidental contact with the moving saw chain.
• Follow instructions for lubricating, chain
tensioning and changing the bar and chain.
Improperly tensioned or lubricated chain may either
break or increase the chance for kickback.
• Cut wood only. Do not use pole pruner for
purposes not intended. For example: do not use
pole pruner for cutting metal, plastic, masonry
or non-wood building materials. Use of the pole
pruner for operations different than intended could
result in a hazardous situation.
• Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid
them. Serious injury could occur to the operator or
bystanders while felling a tree.
• This pole pruner is not intended for tree felling.
Use of the pole pruner for operations different than
intended could result in serious injury to the operator
or bystanders.
• Follow all instructions when clearing jammed
material, storing or servicing the pole pruner.
Make sure the switch is off and the battery
pack is removed. Unexpected actuation of the pole
pruner while clearing jammed material or servicing
may result in serious personal injury.

4 CAUSES AND OPERATOR
PREVENTION OF KICKBACK:
Kickback may occur when the nose or tip of the guide
bar touches an object, or when the wood closes in and
pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards the
operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards the
operator.
Either of these reactions may cause you to lose control
of the saw which could result in serious personal injury.
Do not rely exclusively upon the safety devices built
into your saw. As a pole pruner user, you should
take several steps to keep your cutting jobs free from
accident or injury.
Kickback is the result of pole pruner misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
• Maintain a firm grip, with thumbs and fingers
encircling the pole pruner handles, with both
hands on the saw and position your body and
arm to allow you to resist kickback forces.
Kickback forces can be controlled by the operator,
if proper precautions are taken. Do not let go of the
pole pruner.
• Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact
and enables better control of the pole pruner in
unexpected situations.
• Only use replacement guide bars and saw
chains specified by the manufacturer. Incorrect
replacement guide bars and saw chains may cause
chain breakage and/or kickback.
• Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
