Safe use of a hedge trimmer involves

1.the operator

2.the power tool

3.the use of the power tool.

THE OPERATOR

Physical Condition

You must be in good physical condition and mental health and not under the influence of any substance (drugs, alcohol, etc.) which might impair vision, dexterity or judgment. Do not operate this machine when you are fatigued.

WARNING

Be alert – if you get tired, take a break. Tiredness may result in loss of control. Working with any power tool can be strenuous.Ifyouhaveanyconditionthat mightbeaggravatedbystrenuouswork, check with your doctor before operating this machine.

English

WARNING

Prolonged use of a power tool (or other machines) exposing the operator to vibrations may produce whitefinger disease (Raynaud's phenomenon) or carpal tunnel syndrome.

These conditions reduce the hand's ability to feel and regulate temperature, produce numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.

All factors which contribute to whitefinger disease are not known, but cold weather, smoking and diseases or physical conditions that affect blood vessels and blood transport, as well as high vibration levels and long periods of exposure to vibration are mentioned as factorsinthedevelopmentofwhitefinger disease. In order to reduce the risk of whitefinger disease and carpal tunnel syndrome, please note the following:

HLA 65

English

Most STIHL power tools are available with an anti-vibration ("AV") system designed to reduce the transmission of vibrations created by the machine to the operator's hands. An AV system is recommended for those persons using power tools on a regular or sustained basis.

–Wear gloves and keep your hands warm.

–Keep the AV system well maintained. A power tool with loose components or with damaged or worn AV elements will tend to have higher vibration levels.

–Maintain a firm grip at all times, but do not squeeze the handles with constant, excessive pressure. Take frequent breaks.

All the above-mentioned precautions do not guarantee that you will not sustain whitefinger disease or carpal tunnel syndrome. Therefore, continual and regular users should closely monitor the condition of their hands and fingers. If any of the above symptoms appear, seek medical advice immediately.

Proper Clothing

WARNING

To reduce the risk of injury, the operator should wear proper protective apparel.

WARNING

To reduce the risk of injury to your eyes never operate your power tool unless wearing goggles or properly fitted protective glasses with

adequate top and side protection complying with ANSI Z 87.1 (or your applicable national standard). Wear an approved safety hard hat when there is a risk of head injury.

STIHL recommends the use of sound barriers (ear plugs or ear mufflers) to protect your hearing.

Clothing must be sturdy and snug-fitting but allow

complete freedom of movement. Wear long pants made of heavy material to help protect your legs. Do not wear shorts.

Avoid loose-fitting jackets, scarfs, neckties, jewelry, flared or cuffed pants, unconfined long hair or anything that could become caught on branches, brush or the moving parts of the unit. Secure hair so it is above shoulder level.

Good footing is very important. Wear sturdy boots with nonslip soles.

Never wear sandals, flipflops or go barefoot.

Always wear gloves when handling the machine and the cutting tool. Heavy-duty, nonslip gloves improve your grip and help to protect your hands.

THE POWER TOOL

A self test is performed after the charger isconnectedtothepowersupply.During this process the light emitting diode (1) on the charger lights up green for about 1 second, then red and goes off again.

Charging the Battery

The battery is given a charge of about 30% before leaving the factory.

Recommendation: Fully charge the battery before using your power tool for the first time.

NConnect the charger to the power supply – mains voltage and operating voltage of the charger must be the same – see "Connecting Charger to Power Supply".

Operate the charger only in enclosed and dry rooms at ambient temperatures between 41°F (5°C) and 104°F (40°C).

3901BA009 KN

NPush the battery (1) into the charger (2) until you feel noticeable resistance – then push it as far as stop.

3901BA014 KN

The light emitting diode (3) on the charger comes on when the battery is inserted – see "Light Emitting Diodes (LED) on Charger"

Charging begins as soon as the light emitting diodes (4) on the battery light up green – see "Light Emitting Diodes (LED) on Battery".

The charge time is dependent on a number of factors, including battery condition, ambient temperature, etc., and may therefore vary from the charge time in the "Specifications".

The battery becomes hot during operation. If a hot battery is inserted in the charger, it may be necessary to cool it down before charging. The charging processbeginsonlyafterthebatteryhas cooled down. The time required for cooling may prolong the charge time.

The battery and charger become warm during the charging process.

AL 300 charger

This charger is equipped with a battery cooling fan which is audible when it is running.

HLA 65

AL 100 charger

This charger waits for the battery to cool down before starting the charging process. The battery is cooled normally by heat transfer to the ambient air.

End of charge

The charger switches itself off automatically when the battery is fully charged:

–Light emitting diodes on the battery go off

–The light emitting diode on the charger goes off

–The charger's fan is switched off (if charger is so equipped)

Remove the charged battery from the charger.
