SAFETY WARNINGS General power tool safety warnings WARNING Read all safety warnings, instruc- tions, illustrations and specications provided with this power tool. Failure to follow all instructions listed belowmayresultinelectricshock,reand/orserious injury. Save all warnings and instruc- tions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. General pruner saw safety warnings

1. Keep all parts of the body away from the

saw chain when the pruner saw is operating. Before you start the pruner saw, make sure the saw chain is not contacting anything. A moment of inattention while operating pruner saws may cause entanglement of your clothing or body with the saw chain.

2. Always hold the pruner saw with one hand

on the rear handle and the other hand on the auxiliary handle.

3. Hold the pruner saw by insulated gripping

surfaces only, because the saw chain may con- tact hidden wiring. Saw chains contacting a "live" wire may make exposed metal parts of the pruner saw "live" and could give the operator an electric shock.

4. Wear eye protection. Further protective equip-

ment for hearing, head, hands, legs and feet is recommended. Adequate protective equipment willreducepersonalinjuryfromyingdebrisor accidental contact with the saw chain.

5. Do not operate a pruner saw in a tree, on a lad-

der, from a rooftop, or any unstable support. Operation of a pruner saw in this manner could resultinseriouspersonalinjury.

6. Always keep proper footing and operate the

pruner saw only when standing on xed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the pruner saw.

7. When cutting a branch that is under tension,

be alert for spring back. When the tension in the woodbresisreleased,thespringloadedbranch may strike the operator and/or throw the pruner saw out of control.

8. Use extreme caution when cutting brush and

saplings. The slender material may catch the saw chainandbewhippedtowardyouorpullyouo󰀨 balance.

9. Carry the pruner saw with the pruner saw

switched o󰀨 and away from your body. When transporting or storing the pruner saw, always t the guide bar cover. Proper handling of the pruner saw will reduce the likelihood of accidental contact with the moving saw chain.

10. 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.

11. Cut wood only. Do not use pruner saw for pur-

poses not intended. For example: do not use pruner saw for cutting metal, plastic, masonry or non-wood building materials. Use of the prunersawforoperationsdi󰀨erentthanintended could result in a hazardous situation.

material, storing or servicing the pruner saw. Make sure the switch is o󰀨 and the battery pack is removed.

14. Causes and operator prevention of kickback:

Kickback may occur when the nose or tip of the guidebartouchesanobject,orwhenthewood 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 personalinjury.Donotrelyexclusivelyuponthe safety devices built into your saw. As a pruner saw user, you should take several steps to keep your cuttingjobsfreefromaccidentorinjury. Kickback is the result of pruner saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• Maintain a rm grip, with thumbs and n- gers encircling the pruner saw 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 precau- tions are taken. Do not let go of the pruner11 ENGLISH saw. ►Fig.1

• Do not overreach and do not cut above shoulder height. This helps prevent unin- tended tip contact and enables better control of the pruner saw in unexpected situations.

• Only use replacement guide bars and saw chains specied 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.

15. Follow all instructions when clearing jammed

material, storing or servicing the pruner saw. Make sure the switch is o󰀨 and the battery pack is removed. Additional Safety Instructions Personal protective equipment
