SAFETY PRECAUTIONS

General precautions

• In order to ensure safe operation, the operator must read this instruction manual to familiarize him or herself with the operation of the hedge trimmer. Users insufficiently informed will endanger themselves as well as others due to improper handling.
• First-time users should have an experienced hedge-trimmer user show them how to use the trimmer.
• Lend the hedge trimmer only to persons who are experienced in the use of such machines. Always give the the instruction manual.
• Persons under 18 years of age must not be allowed to operate the hedge trimmer. Persons over the age of 16 years may, however, use the hedge trimmer for instructional purposes as long as they are under the supervision of a qualified individual.
• Always pay the utmost attention when using the hedge trimmer!
• Use the hedge trimmer only if you are in good physical condition. If you are tired, your attention will be reduced. Be especially careful at the end of a working day. Perform all work calmly and carefully. The user is responsible for all damages to third parties.
• Never use the trimmer when under the influence of alcohol, drugs or medication.

Protective equipment

In order to prevent, eye, hand and foot injuries as well as hearing loss, always wear the protective clothing and gear described in the flooring when working with the hedge trimmer.
- Clothing should be appropriate, i. e. snugly fitting but not so tight as to be a hindrance. Do not wear jewellery or clothing which could get caught on twigs and branches. If you have long hair, always wear a hairnet!
- The protective glasses or goggles keep cut material out of your eyes and prevent eye injuries. Always wear eye protection when using the hedge trimmer!

• Wear adequate hearing protection equipment (ear muffs, ear plugs, etc.). Octave brand analysis upon request.
• Work gloves of stout leather are part of the basic equipment of the hedge trimmer and must always be worn when working with it.
• When using the trimmer always wear sturdy shoes with anti-skid soles.

Starting operation

• Before starting work check to make sure that the trimmer is in good and safe working order. This is a must!
• Do not use the hedge trimmer in the rain or in wet or very damp conditions. The electric motor is not waterproof.
• Do not use the hedge trimmer if it is wet or damp.
• Do not use the hedge trimmer near combustible gases or dust. The motor generates sparks. Explosion hazard!
• Check to make sure that the voltage and frequency of the power supply correspond to the specifications given on the indentification plate. Max. back-up fuse 16 A. We recommend the use of a residual-current-operated circuit breaker (ground-fault circuit interruptor) or an earth leakage current protector.
• Make sure that no children or other persons are within 5 meters (17 feet) of the unit during operation. Watch out for animals.
• The hedge trimmer must not be used unless fully assembled!
• Make sure you have a secure footing before starting operation.

• Do not start the hedge trimmer without having a firm grip on both handles with both hands! The trimmer is designed for use by left- or right-handers, and can be used on both sides equally well.

• NEVER affix the grip safeties in the down position!

• Operate the hedge trimmer only in the manner prescribed by the instruction manual.
• Switch off the hedge trimmer immediately if you notice any change in its behaviour.
• Immediately unplug the mains plug if the power cord should become damaged or severed.
• Immediately switch off the motor and unplug the mains plug if the cutter should come into contact with a fence or other hard object. Check the cutter for damage.
• Before checking the cutter, taking care of faults, or removing material caught in the cutter, always switch off the trimmer and unplug the mains plug.
  Before taking breaks and before leaving the hedge trimmer unattended, always switch it off and unplug the mains plug. Place the trimmer in such a way that it cannot endanger anyone.

Extension power cord

• Use only splash-proof extension cords that are approved for outdoor use and marked as such.
• When selecting an extension cord, give preference to cords in fluorescent or eye-catching colours.
• The hedge trimmer is protectively insulated in accordance with VDE (German Electricians' Association) Standard 0740 Class II, and can therefore be connected to plug sockets without ground contact.
• Always work in such a way that the extension power cord is behind you!
• Always start near the power source and work away from it. This ensures that the extension cord stays behind the work area.
• The trimmer power cord must likewise always be behind the operator. Make sure that it does not get caught, or comes into contact with sharp objects. Route the cord in such a way that no persons can be endangered.

Important: Work especially carefully when the extension cord has to be routed over the hedge!

• Do not use any extension cord with a line cross-section of less than 3 × 1.5 ~mm^2 . When using a reel, make sure that the cord is completely unrolled. The cord length must not exceed 30 ~m / 100 ft

Transportation and storage

• When moving the hedge trimmer to another location, including during work, always unplug the mains plug.

• Never carry or transport the trimmer with the cutter running!

• Never grasp the cutter with your hands!

• When transporting the hedge trimmer for more than short distances, always put on the sheath supplied with the unit.

• Carry the trimmer only by the front handle. The cutter should be pointing backwards.

• When carrying the hedge trimmer in a vehicle, make sure it is in a secure position. It should be transported only in the trunk or in a transport area separate from the driver.
• Store the hedge trimmer with the sheath on, in a dry room. Keep it out of reach of children. Never store the trimmer outdoors.
• Clean the hedge trimmer and especially the cutter after use, and before putting the trimmer into storage for extended periods. Lightly oil the cutter and put on the sheath. The sheath supplied with the unit can be hung on the wall, providing a safe and practical way to store the hedge trimmer.

Maintenance

• Switch off the trimmer and disconnect and secure the mains plug before doing any maintenance work.

• Make especially sure the cutter is undamaged and in good condition.
• Regularly inspect the power cord for damage to the insulation. If the power cord is damaged, disconnect the mains plug.
• Regularly clean the trimmer.
• If the plastic housing is damaged, have the unit repaired by a qualified service technician immediately. Shock hazard! Danger of injury!

Follow the accident-prevention instructions and recommendations of your trade association or insurer.

Do not make any modifications to the hedge trimmer. Doing so will only endanger your safety.

Perform only the maintenance and repair works described in the instruction manual. All other work must be carried out by MAKITA Service.

Use only original MAKITA spare parts and accessories.

Using other than original MAKITA parts or accessories brings a high risk of accidents. We cannot accept any responsibility for accidents and damage resulting from non-MAKITA parts and accessories which have not been approved.

First aid

For the event of a possible accident, please make sure that a first aid kit is always immediately available close by. Immediately replace any items used from the first aid box.

When calling for help, give the following information:

• Place of the accident
• What happened
  Number of injured
• Kind of injuries
• Your name!

NOTE

Individuals with poor circulation who are exposed to excessive vibration may experience injury to blood vessels or the nervous system.

Vibration may cause the following symptoms to occur in the fingers, hands or wrists: "Falling asleep" (numbness), tingling, pain, stabbing sensation, alteration of skin colour or of the skin. If any of these symptoms occur, see a physician!

Working technique

• Work only in good lighting and visibility.
• Never work on an unstable surface. Pay attention to obstacles in the work area - risk of stumbling! Pay constant attention to good footing.
• Never work while standing on a ladder.
• Do not bend too far over while working.
• Guide the trimmer away from your body, with the cutter pointing away and at a safe distance from your body.
• Use the hedge trimmer only for trimming hedges! Do not use it for cutting grass or brash.
• Always keep the ventilation slots unobstructed, to ensure proper cooling of the electric motor.

• Do not allow the cutter to touch the ground when running. Foreign objects will damage the cutter and may lead to injury.

• Do not use the trimmer to lift, lever, or sweep away cut material or other objects.

• Cut thick branches to length with pruning shears before trimming the hedge.

• Do not start working until you have made sure that:

a) No other persons or animals are within the working area.
b) The trimmer operator can step back unhindered in the event of an emergency.
c) The ground is free of all foreign objects, brush, and branches. The operator must have a sure footing (risk of stumbling).

Tips on trimming hedges

The procedure described here can be used very often and makes working easier. If a hedge has to be cut back very substantially, it should be trimmed in two passes.

• First cut the hedge to the desired height (1). With practice, it is possible to remove cut material from the hedge with a swinging motion. To get a straight cut, stretch a string along the hedge at the desired height.

• Trim the hedge to a trapezoidal shape (about 10 cm / 4 in at the top for every 1 m / 3 '3" of height), cutting from bottom to top (2). In this way you avoid cut material falling down into the area not yet cut.

• Round off the top edges of the hedge (3), and finally trim the bottom edges back somewhat (4).

The best times to trim hedges are:

Broad-leaf hedges: June and October

Coniferous hedges: April and August

Fast-growing hedges: About every 6 weeks starting in May

Environmental protection information

Do not use the hedge trimmer during times when people are likely to be resting.

Before trimming a hedge, check to make sure that no birds are nesting in it. If they are, wait until the young have left the nest before trimming near that part of the hedge.

Dispose of cut material in an environment-friendly way, or compost it.
