5 GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings and all instructions. Failure to follow all warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains operated (corded) power tool or battery operated (cordless) power tool.

5.1 Work area

 Keep work area clean and well lit. Cluttered and dark areas invite accidents.  Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

 Keep children and bystanders away while operating a power tool. Distractions can cause

you to lose control.

5.2 Electrical safety

Always check that the power supply corresponds to the voltage on the rating plate.

 Power tool plugs must match the outlet. Never modify the plug in any way. Do not use

any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

 Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges

and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

 Do not expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

 Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power

tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

 When operating a power tool outdoors, use an extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces the risk of electric shock.

 If operating a power tool in a damp location is unavoidable, use a residual current device

(RCD) protected supply. Use of an RCD reduces the risk of electric shock.

5.3 Personal safety

 Stay alert, watch what you are doing and use common sense when operating a power

tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

 Use safety equipment. Always wear eye protection. Safety equipment such as dust

mask, non-skid safety shoes, hard hat, or hearing protection used whenever conditions require will reduce personal injuries.

 Avoid accidental starting. Ensure the switch is in the off position before plugging in.

Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

 Remove any adjusting key or wrench before turning the power tool on. A wrench or a

key left attached to a rotating part of the power tool may result in personal injury.

 Do not overreach. Keep proper footing and balance at all times. This enables better

control of the power tool in unexpected situations.

 Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and

gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

POW64251 EN

 If devices are provided for the connection of dust extraction and collection facilities,

ensure these are connected and properly used. Use of these devices can reduce dust related hazards.

5.4 Power tool use and care

 Do not force the power tool. Use the correct power tool for your application. The correct

power tool will do the job better and safer at the rate for which it was designed.

 Do not use the power tool if the switch does not turn it on and off. Any power tool that

cannot be controlled with the switch is dangerous and must be repaired.

 Disconnect the plug from the power source before making any adjustments, changing

accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

 Store idle power tools out of the reach of children and do not allow persons unfamiliar

with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

 Maintain power tools. Check for misalignment or sticking of moving parts, breakage of

parts and any other condition that may affect the power tool’s operation. If damaged,

have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

 Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting

edges are less likely to stick and are easier to control.

 Use the power tool, accessories and tool bits etc., in accordance with these instructions

and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from intended could lead to a hazardous situation.

5.5 Service

 Have your power tool serviced by a qualified repair person using only identical

replacement parts. This will ensure that the safety of the power tool is maintained.

6 PARTICULAR SAFETY PRECAUTIONS WHEN WORKING WITH

THE CHAIN SAW

 When working with the chain saw, protective gloves, suitable shoes, leg protectors, eye

protectors and ear protectors should be used.

 If the work involves any risk of head injury, a safety helmet must be worn When cutting

down trees and cutting and cutting off branches of felled or fallen trees. in addition a face protector should be worn.

 Always pull the plug from the socket outlet before attempting to check or adjust the chain

or to correct some fault and whenever moving one workplace to another.

 Never switch on the chain saw unless you have a firm hold of the tool. a secure footing

and are sure that the guide bar and saw chain are not touching anything.

 Always hold the saw with both hands (right hand on rear handle, left hand on handle 5).  Never saw above shoulder height, while standing on a ladder or In a tree or in any other

insecure position.

 When sawing timber that has split, take particular care that no small pieces of wood are

broken off and thrown by the saw chain.

 During breaks, the saw should be laid down in such a way that there Is no risk of injury

to anyone from the saw chain.

 The chain saw should never be lent to or be allowed to come into the hands of persons

who are not familiar with the use of such a tool. The operating Instructions should also go with the saw.

POW64251 EN

Rotational kickback A = kickback path B = kickback reaction zone

7 KICKBACK SAFETY PRECAUTIONS

KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back toward the operator. PINCHING the saw chain along the BOTTOM of the guide bar may PULL the saw forward away from the operator. PINCHING the saw chain along the TOP of the guide bar may PUSH the guide bar rapidly back toward the operator. Any of these reactions may cause you to lose control of the saw, which could result in serious personal injury.  With a basic understanding of kickback, you can reduce or eliminate the element of

surprise. Sudden surprise contributes to accidents.

 Keep a good firm grip on the saw with both hands, the right hand on the rear handle, and

the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don’t let go.

 Make sure that the area in which you are cutting is free from obstructions. Do not let the

nose of the guide bar contact a log, branch, or any other obstruction which could be hit while you are operating the saw.

 Cut at high engine speeds.  Do not overreach or cut above shoulder height.  Follow manufacturer’s sharpening and maintenance instructions for the saw chain.  Only use replacement bars and chains specified by the manufacturer or the equivalent.

NOTE: Low-kickback saw chain is chain that has met the kickback performance.

WARNING: Kickback can lead to dangerous loss of control of the chain saw and result in serious or fatal injury to the saw operator or to anyone standing close by. Always be alert. Rotational kickback and pinch-kickback are major chain saw operational dangers and the leading cause of most accidents.

Beware of:

The push (pinch kickback) and pull reactions a = pull B = solid objects C = push

8 ASSEMBLY

8.1 Fitting the guide bar and chain

If the chain saw is already connected to the power supply: Pull the plug from the socket outlet. Wear protective gloves whenever doing any work on the saw chain.

POW64251 EN

Fig 1

POW64251 EN

Fig 2

The chain must be fitted over the guide bar so that the cutting edges of the cutters (a) face in the direction that the chain runs.

The direction of rotation of the saw chain is indicated by two arrows on the drive-sprocket cover. Hold the guide bar with the nose up-wards and place the saw chain so on the blade. Then put the saw chain round the drive sprocket and place the guide bar with its slot so onto the threaded studs(11). Replace the drive-sprocket cover(1)and screw on the lock-on hand wheel (2 and 4) but do not yet tighten them.

Turn the tensioning screw (4) clockwise to take up any slack in the saw chain. The chain is correctly tensioned when it is still possible to raise it by 3-4mm in the middle of the guide bar (fig 3).

After tensioning the saw chain turn the nose of the bar upwards and tighten the lock-on hand wheel (2 and 4) firmly.

8.2 Lubricating oil for the saw chain

 Before starting up your new chain saw, the container must be filled with chain saw oil.  It allows operating the chain saw at ambient temperatures down to as low as -15°C.  Never use waste oil for lubricating the saw chain.  To top the saw up with lubricating oil unscrew the filler cap (3). Make sure that no dirt

gets into the oil container while filling up. The oil level can be checked through the gauge glass (14)

9 POWER SUPPLY CONNECTION

 The chain saw has purposely been fitted with a comparatively short power lead to

reduce the risk of the lead being cut by the saw chain while working with the tool.

 It is best to fit the strain relief strap supplied between the plug on the saw’s power lead

and the coupler socket on the extension cord, to prevent the plug from being unintentionally pulled out of the coupler socket.

 Before plugging the extension cord into the supply socket check the cord for damage

and deterioration. Never operate the chain saw if the supply lead is not in perfect condition.

 The electricity supply where the chain saw is connected to should be provided with an

earth leakage or residual current device with a tripping current of not more than 30mA.

POW64251 EN

10 OPERATION

10.1 Switching on and off

When switching the chain saw on, the hand-protection guard (6) must be in its normal position, i.e. be pressed in the direction of the arrow in Fig 1 against the handle (5). The saw is provided with a safety device to prevent it being switched on accidentally. To switch on:

 -Grasp the handle (5) with the left hand  -With the thumb of the right hand push the locking button at the left side of the switch

handle, then

 -With the locking button still depressed, squeeze the trigger and  -Release the locking button

To switch off:

 -Release the trigger. (the locking button returns into the locked position) The noise that the chain saw not being fitted with the guide bar and chain makes while the tool is running down, is quite natural and has no ill effect on the function or service life of the saw.

10.2 Running the saw chain in

Before starting to saw, a new saw chain should be run in for 2-3 minutes and then its tension should be checked as detailed under “fitting the guide bar and saw chain” and the chain be retensioned if necessary.

10.3 Checking the chain lubrication

Running the saw chain without chain lubrication will quickly damage the chain and the guide bar beyond repair and so you should always check the oil level before starting up.

Never run the saw without chain lubrication.

TO check the lubricating system switch on the chain saw and hold it with the guide bar and chain above some light coloured area (an open newspaper will . A steadily increasing stain caused spray shows that the lubricating system is working properly.

10.4 Chain brake

The saw is fitted with a chain brake that brings the saw chain to a stop a tenth of a second

 if the hand-protection guard (6) is brought into the tripping position either manually or.

 while operating the chain saw, as a result of a kickback, by the back of the operator's hand

 if the chain saw is switched off by releasing the trigger.

When the chain brake has been tripped by actuating the hand-protection guard (6), do not run the motor of the saw unnecessarily long. Set the guard immediately back to its normal position.

Before starting any work with the chain saw, be sure to check the proper functioning of the chain brake (by actuating the hand-protection guard and by releasing the trigger).

POW64251 EN

If the upper part of the guide-bar nose should inadvertently be allowed to Touch against some rigid objects, such as the bole of the tree when sawing off branches, or some immediately adjacent object, a trunk lying close to the one that is to be cut through, for instance, the saw with the guide bar may kick back and upwards against the operator in the direction of the arrow in Fig.4.

Push-back will occur it an attempt is made to saw with the saw chain at the top the guide bar, if this part of the saw chain touches against some rigid object or if it jams in the cut.

If the spiked stop is not set against the timber that is to be sawn, the chain at the bottom of the guide bar will pull the saw forward if the chain jams or comes against some solid object in the timber. It is therefore important to saw with the spiked stop against the timber whenever possible.

10.5 Kickback

Such dangerous kickbacks can largely be avoided by working quietly and with forethought in the following manner:

 While sawing, always watch the guide-bar nose

 Never attempt to cut with the nose of the guide bar.

 Take care when cutting thin and springy branches. The saw chain can easily catch against

them. Particular care must be taken when inserting the saw with the guide bar to complete an already started cut.

10.6 Push-back

10.7 Pull-forward

11 HOW TO WORK WITH THE CHAIN SAW

Each time you are about to start work, check that the saw is in perfect condition. It is particularly important to ensure that the guide bar is properly fitted, that the chain is correctly tensioned and that the chain brake is functioning correctly. Before using the saw for the first time it is advisable to practise cutting logs on a saw-horse or something alike. When working with the chain saw, care should be taken to keep the extension cord away from the saw chain.

POW64251 EN

When cutting timber with the chain saw, the left arm should be kept almost straight Guide the saw so that no part of your body extends beyond the imaginary line «X» drawn through the guide bar. Press the spiked stop (10) on the saw against the timber and only then start cutting holding the tool by the handle (5) and raising the switch handle.

Fig 8

11.1 Cutting logs, branches, etc.

If you cannot cut the timber right Through with a single stroke:

 Apply light pressure to the handle(5) and continue sawing and  Draw the chain saw back a little, then  Apply the spiked stop a little lower and  finish the cut by raising the switch handle

Withdraw the saw from the cut while the chain is still running. When cutting timber resting on the ground, never allow the saw chain to cut into soil under the timber; this would dull the chain immediately. When cutting trunks resting on a slope, the operator should always stand uphill of the trunk.

11.2 Trimming trees

When trimming trees, always cut from above to allow the branch to drop away downwards It may however be useful to cut into the branch from below first. When cutting off a branch the chain saw should be supported against the bole of the tree if at all Possible. Never attempt to cut off branches with the nose of the guide bar. Particular care should be taken when sawing through a branch that is under tension and that might spring up and hit you.

11.3 To fell a tree

Before commencing to cut down a tree, you must be clear where you want it to fall and be sure that there is nothing in the way, such as power lines or a building that could be damaged when the tree falls. NO person or animal must be within 2 1/2 tree lengths of the base of the tree. You should clear two escape routes. Each opening put at an angle of about 45 in the direction opposite to that in which you plan that the tree should fall (Fig.10). These escape routes must be clear and free of obstruction.

POW64251 EN

First an undercut notch has to be cut in the trunk of the tree to determine the direction in which the tree is to fall. The undercut, which should have a, depth equal to about a quarter of the diameter of the trunk, should first be sawn downwards at an angle and then horizontally across to meet the top cut (Fig. 11).

The felling cut ③should be made slightly above the level of the bottom of the undercut. This cut should not extend right through but should leave an uncut breakage strip ② Otherwise the tree could fall out of control. The breakage strip should have a width of about one tenth the

diameter of the trunk. Wedges should be driven into the felling cut in good time. Only wedges of wood, aluminium or plastic should be used never wedges of iron or steel.

12 CLEANING AND MAINTENANCE

12.1 Re-tensioning the saw chain

When working with the chain saw, the chain expands as a result of the warming. It then becomes slack and may slip off the guide bar. If the saw chain is tensioned in this condition, it is very important to release the tension once the saw work is finished, as otherwise the chain may contract so much on cooling that it will be excessively tight.

12.2 Insufficient chain lubrication

If after running the chain saw for about 20 minutes only a little lubricating oil has left the container, the cause may be blockage of the oil duct (8) in the saw and/or the oil hole (16) in the guide bar. If so, they should be cleaned. To clean the oil duct (8) the cover plate (7) can be removed, if necessary, after unscrewing its fastening screw.

12.3 To carry the chain saw

After use, the guide bar and chain should be covered with the chain guard that is supplied with the tool.

12.4 Saw chains

Working with a blunt saw chain causes the chain, guide bar and drive sprocket to wear rapidly and may even lead to the chain breaking and so it is important that the saw chain be sharpened in good time. It is advisable to have the chain be re-sharpened by a competent workshop. The relevant angles on the saw-chain cutters are: side-plate filing angle 85° top-plate cuffing angle 60° top-plate angle 30° A 4 mm dia. round file should be used for sharpening the chain.

12.5 Guide bar

A small amount of ball-bearing grease should be fed occasionally with a grease gun through the grease holes situated near the four rivets holding the nose sprocket on the guide bar. The bottom edge of the bar is exposed to relatively heavy wear and so the bar should be turned top to bottom whenever the chain is sharpened and at the same time the groove in the bar and the oil holes (16) should be cleaned.

12.6 Drive sprocket

If the teeth of the drive sprocket (13) show any signs of wear. the sprocket should be replaced. The drive sprocket should be changed with every second replacement of the chain.

12.7 Carbon brushes

When the chain saw's brushes are worn beyond a certain limit, a tripping device in the brushes automatically stops the motor. The brushes should be replaced by a specialist who has the right equipment. The saw can then be given a thorough inspection at the same time and the motor be cleaned.
