Kickback safety precautions
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.
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 lightningfast reverse reaction, kicking the guide bar up and back toward the operator.
Helpline No. UK 0151 649 1500 / IRE 189 094 6244
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.
Beware of the following: Rotary recoil (Fig. 1)
A = Recoil distance
B = Recoil reaction zone

To prevent pulling reactions, place the wood you wish to cut against the claw stop. Use the claw stop as a pivot point during cutting (Fig. 2).
Safety Instructions
Warning: When using petrol tools, basic safety precautions, including the following, should always be followed to reduce the risk of serious personal injury and/or damage to the unit.
Read all these instructions before operating this product and save these instructions
1. DO NOT operate a chain saw with one hand!
Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chainsaw is intended for two- handed use.
2. Do NOT use the saw if you are tired, ill or under the influence of alcohol and/or drugs.
3. Use safety footwear, snug-fitting clothing, protective gloves, and eye, hearing and head protection devices.
4. Use caution when handling fuel. Move the chainsaw at least 10 feet (3m) from the fueling point before starting the engine.
5. DO NOT allow other persons to be near when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.
6. DO NOT start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.
7. Keep all parts of your body away from the saw chain when the engine is running.
8. Before you start the engine, make sure that the saw chain is not contacting anything.
9. Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the exhaust away from your body.
10. NEVER use a chainsaw which is damaged, incorrectly set or incompletely and loosely assembled. Make sure that the chainsaw stops when the chain brake is applied.
11. Shut off the engine before setting the chain saw down.
12. Use extreme caution when cutting small size brush and saplings because slender material
Helpline No. UK 0151 649 1500 / IRE 189 094 6244
05
06 may catch the saw chain and be whipped toward you or pull you off balance.
13. When cutting a limb that is under tension, be alert for springback so that you will not be struck when the tension in the wood fibres is released.
14. Keep the handles dry, clean, and free of oil or fuel mixture.
15. Operate the chain saw only in well-ventilated areas.
16. DO NOT operate a chain saw in a tree unless you have been specifically trained to do so.
17. All chain saw service, other than the items listed in the user manual safety and maintenance instructions, should be performed by competent chain saw service personnel.
18. When transporting your chain saw, use the appropriate guide bar scabbard.
19. DO NOT operate your chain saw near or around flammable liquids or gases whether in or out of doors. An explosion and/or fire may result.
20. Do not fill fuel tank, oil or lubricate when the engine of chain saw is running.
21. USE THE RIGHT TOOL: Cut wood only. Do not use the chain saw for purposes for which it was not intended. For example, do not use the chain saw for cutting plastic, masonry, or non building materials.
22. The engine will create toxic exhaust fumes as soon as the engine is started. Never work in enclosed rooms or in rooms with poor ventilation.
23. If your fingers become white or you feel an awkward feeling (prickle) in your fingers, stop working immediately!
Note: The chainsaw is designed for occasional use by home owners, garden owners and campers and is for general work such as stump grubbing, cutting firewood, etc. It is not designed for lengthy use. If it is used for a lengthy period, the vibrations it causes in the hands of the user may result in circulation problems (white finger syndrome).
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. If the bar tip contacts, it may cause a lightning-fast 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 loose 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 chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.
1. With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.
2. 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.
3. 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.
4. Cut at high engine speeds.
5. Do not overreach or cut above shoulder height.
6. Follow manufacturer’s sharpening and maintenance instructions for the saw chain.
7. Only use replacement bars and chains specified by the manufacturer or the equivalent.
Safety features (Fig. 3A)
2. LOW KICKBACK SAW CHAIN helps significantly reduce kickback, or the intensity of kickback, due to specially designed depth gauges and guard links.
5. CHAIN BRAKE LEVER / HAND GUARD protects the operator’s left hand in the event it slips off the front handle while saw is running.
5. CHAIN BRAKE is a safety feature designed to
Helpline No. UK 0151 649 1500 / IRE 189 094 6244
3A reduce the possibility of injury due to kickback by stopping a moving saw chain in milliseconds. It is activated by the CHAIN
BRAKE lever.
10. STOP SWITCH immediately stops the engine when tripped. Stop switch must be pushed to
“On (1)” position to start or restart engine.
11. SAFETY TRIGGER prevents accidental acceleration of the engine. Throttle trigger (19) cannot be squeezed unless the safety latch is depressed.
20. CHAIN CATCHER reduces the danger of injury in the event saw chain breaks or derails during operation. The chain catcher is designed to intercept a whipping chain.
Note: Study your saw and be familiar with its parts.
Proper use
The chain is designed exclusively for sawing wood. You may only fell trees if you have received the appropriate training. The manufacturer cannot be held liable for damage caused by improper or incorrect usage.
Please note that our equipment has not been designed for use in commercial, trade or industrial applications. Our warranty will be voided if the machine is used in commercial, trade or industrial businesses or for equivalent purposes.
Additional Risks:
Even if the chainsaw is used correctly, there are still risks of harm or injury associated with the tool’s use. Beware of the following risks: n Contact with an unprotected saw chain
(cutting damage) n Grasping a moving saw chain
(cutting damage) n Unexpected movement of the chainbar
(cutting damage) n Parts being thrown from the chain, if the chain breaks n Material pieces (wood chips, etc.) being thrown from the chain during use n Not using the specified ear protection will cause hearing damage n Inhaling parts of material, or exhaust fumes from the combustion engine n Petrol contacts with the skin

Saw chain tension adjustment
Proper tension of the saw chain is extremely important and must be checked before starting, as well as during any cutting operation. Taking the time to make needed adjustments to the saw chain will result in improved cutting performance and prolonged chain life.
Warning: Always wear heavy duty gloves when handling saw chain or making saw chain adjustments.
1. Before adjusting the chain tension screw you must slacken the 2x retaining nuts. Otherwise this will damage the tension screw.
2. Hold nose of guide bar up and turn adjustment screw (G) CLOCKWISE to increase chain tension. Turning screw
COUNTERCLOCKWISE will decrease amount of tension on chain. Ensure the chain fits snugly all the way around the guide bar (Fig. 10).
3. After making adjustment, and while still holding nose of bar in the uppermost position, tighten the bar retaining nuts securely. Chain has proper tension when it has a snug fit all around and can be pulled around by gloved hand.
Note: If chain is difficult to rotate on guide bar or if it binds, too much tension has been applied.
This requires minor adjustment as follows:
4. Loosen the bar retaining nut so they are finger tight. Decrease tension by turning the bar adjustment screw COUNTERCLOCKWISE slowly. Move chain back and forth on bar.
Continue to adjust until chain rotates freely, but fits snugly. Increase tension by turning bar adjustment screw CLOCKWISE.
5. When saw chain has proper tension, hold nose of bar in the uppermost position and tighten the bar retaining nut securely.
Caution: A new saw chain stretches, requiring adjustment after as few as 5 cuts. This is normal with a new chain, and the interval between future adjustments will lengthen quickly.
Caution: If the saw chain is TOO LOOSE or
TOO TAUT, the drive wheel, chain bar, chain and crank shaft bearing will suffer premature wear.
Fig. 12 shows the correct tension A (when cold) and tension B (when warm). Fig. C shows a chain that is too loose.

3. Getting started
Before starting the machine
Chain break mechanical test
Your chain saw is equipped with a Chain brake that reduces possibility of injury due to kickback.
The brake is activated if pressure is applied against brake lever when, as in the event of kickback, operator’s hand strikes the lever. When the brake is actuated, chain movement stops abruptly.
13
To test chain brake
1. The Chain brake is DISENGAGED (chain can move) when BRAKE LEVER IS PULLED BACK
AND LOCKED (Fig. 13).
2. The chain brake is ENGAGED (the chain is locked) when the brake lever is pulled forward and the mechanism (Fig. 14/Item A) can be seen. It should not be possible to move the chain (Fig. 14).
Note: The brake lever should snap into both
Warning: The purpose of the chain brake is to reduce the possibility of injury due to kickback; however, it cannot provide the intended measure of protection if the saw is operated carelessly. Always test the chain brake before using your saw and periodically while on the job.

Fuel and lubrication
Fuel
Use regular grade unleaded fuel mixed with
40:1custom 2-cycle engine oil for best results.
15
Mixing fuel
Mix fuel with 2 cycle oil in an approved container.
Shake gently and ensure thorough mix.
Warning: Never use straight fuel in your unit.
This will cause permanent engine damage and void the manufacturer’s warranty for that product. Never use a fuel mixture that has been stored for over 90 days.
Engine pre-start checks
Warning: Never start or operate the saw unless the bar and chain are properly installed.
1. Fill the fuel tank (A) with correct fuel mixture
(Fig. 15).
2. Fill the oil tank (B) with chain oil (Fig. 15).
3. Be certain the chain brake is disengaged (C) before starting unit (Fig. 15).
Once you have filled the chain and oil tank, tighten the tank cover securely by hand. Do not use any tools to do so.
4. Features
Warning: If 2-cycle lubricant is to be used, it must be a premium grade oil for 2-cycle air cooled engines mixed at a 40:1 ratio. Do not use any 2-cycle oil product with a recommended mixing ratio of 100:1. If insufficient lubrication is the cause of engine damage, it voids the manufacturer’s engine warranty for that occurrence.
Recommended fuels
Some conventional fuels are being blended with oxygenates such as alcohol or an ether compound to meet clean air standards. Your engine is designed to operate satisfactorily on any fuel intended for automotive use including oxygenated fuel. It is recommended to use unleaded petrol as fuel.
Lubrication of chain and chain bar
Whenever you refill the fuel tank with petrol you must also top up the level of chain oil in the chain oil tank. It is recommended to use standard chain oil. n 45cm cutting length n Automatic choke & primer assisting start up n 21m/s chain speed n 550ml fuel tank capacity n Mixer bottle included

General cutting instructions
Important: Felling trees is prohibited without the necessary training!
Felling
Felling is the term for cutting down a tree.
Small trees up to 6-7 inches (15-18cm) in diameter are usually cut in a single cut.
Larger trees require notch cuts. Notch cuts determine the direction the tree will fall.
Warning: A retreat path (A) should be planned and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Fig. 20.
Warning: If felling a tree on sloping ground, the chain saw operator should keep on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled.
Note: Direction of fall (B) is controlled by the notching cut. Before any cuts are made, consider the location of larger branches and natural lean of the tree to determine the way the tree will fall (Fig. 20).
Warning: Do not cut down a tree during high or changing winds or if there is a danger to property. Consult a tree professional. Do not cut down a tree if there is a danger of striking utility wires; notify the utility company before making any cuts.
General guidelines for felling trees (Fig. 21)
Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut (D). Start making the upper notch cut (C) on the side of the tree facing the felling direction (E).
Be sure you don’t make the lower cut too deep into the trunk. The notch (C) should be deep enough to create a hinge (F) of sufficient width and strength. The notch should be wide enough to direct the fall of the tree for as long as possible.
Warning: Never walk in front of a tree that has been notched. Make the felling cut (D) from the other side of the tree and 1.5-2.0 inches (3-5 cm) above the edge of the notch (C). Never saw completely through the trunk. Always leave a hinge. The hinge guides the tree. If the trunk is completely cut through, control over the felling direction is lost.
Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move. This will prevent the guidebar from binding in the felling cut if you have misjudged the falling direction. Make sure no bystanders have entered the range of the falling tree before you push it over.
Warning: Before making the final cut, always recheck the area for bystanders, animals or obstacles.

Felling cut
1. Use wooden or plastic wedges (A) to prevent binding the bar or chain (B) in the cut.
Wedges also control felling (Fig. 22).
2. When diameter of wood being cut is greater than the bar length, make 2 cuts as shown
(Fig. 23).
Warning: As the felling cut gets close to the hinge, the tree should begin to fall. When tree begins to fall, remove saw from cut, stop engine, put chain saw down, and leave area along retreat path (Fig. 20).
Limbing
Limbing a tree is the process of removing the branches from a fallen tree. Do not remove supporting limbs (A) until after the log is bucked
(cut) into lengths (Fig. 24). Branches under tension should be cut from the bottom up to avoid binding the chain saw.
Warning: Never cut tree limbs while standing on tree trunk.
Bucking
Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log when cutting on sloping ground. If possible, the log should be supported so that the end to be cut off is not resting on the ground. If the log is supported at both ends and you must cut in the middle, make a downward cut halfway through the log and then make the undercut. This will prevent the log from pinching the bar and chain. Be careful that the chain does not cut into the ground when bucking as this causes rapid dulling of the chain. When bucking on a slope, always stand on the uphill side.
1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into the ground (Fig. 25).
2. Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid splintering. Second, cut from above
(overbuck) to meet first cut and avoid pinching (Fig. 26).
3. Log supported on both ends: First, overbuck
1/3 diameter of log to avoid splintering.
Second, underbuck to meet first cut and avoid pinching (Fig. 27).
Note: The best way to hold a log while bucking is to use a sawhorse. When this is not possible, the log should be raised and supported by the limb stumps or by using supporting logs. Be sure the log being cut is securely supported.

Chain bar maintenance
Regular lubrication of the chain bar (guide rail for the chain and teeth) is essential. The chain bar needs the maintenance described in the following section in order for the saw to work at an optimum level of performance.
Caution: The sprocket tip on your new saw has been pre-lubricated at the factory. Failure to lubricate the guide bar sprocket tip as explained below will result in poor performance and seizure, voiding the manufacturer’s warranty.
Tools for lubrication
The Lube Gun is recommended for applying grease to the guide bar sprocket tip. The Lube
Gun is equipped with a needle nose tip which is necessary for the efficient application of grease to the sprocket tip.
To lubricate sprocket tip
Lubrication of the sprocket tip is recommended after 10 hours of use or once a week, which ever occurs first. Always thoroughly clean guide bar sprocket tip before lubrication.
Note: The saw chain does not have to be removed in order to lubricate the teeth of the chain bar. Lubrication is possible during work, with the engine switched off.
Warning: Wear heavy duty work gloves when handling the bar and chain.
1. Set the On/Off switch to “Stop (0)”.
2. Clean the guide bar sprocket tip.
3. Using the Lube Gun (optional), insert needle nose into the lubrication hole and inject grease until it appears at outside edge of sprocket tip (Fig .34).
4. Rotate saw chain by hand. Repeat lubrication procedure until the entire sprocket tip has been greased.
Helpline No. UK 0151 649 1500 / IRE 189 094 6244
Most guide bar problems can be prevented merely by keeping the chain saw well maintained.
Insufficient guide bar lubrication and operating the saw with chain that is TOO TIGHT will contribute to rapid bar wear.
To help minimise bar wear, the following guide bar maintenance procedures are recommended.
Warning: Always wear protective gloves during maintenance operations. Do not carry out maintenance when the engine is hot.
Turning the chain bar
The bar should be reversed every 8 working hours to ensure uniform wear. Keep the bar groove and lubrication hole clean using the bar groove cleaner supplied optional. (Fig. 35)
Check the bar rails frequently for wear and, if necessary, remove the burs and square-up the rails using the flat file (Fig. 36).
Warning:
Never fit a new chain to a worn chain bar.
Oil passages
Oil passages on the bar should be cleaned to ensure proper lubrication of the bar and chain during operation.
Note: The condition of the oil passages can be easily checked. If the passages are clear, the chain will automatically give off a spray of oil within seconds of starting the saw. Your saw is equipped with an automatic oiler system.
Automatic chain lubrication
The chain saw is equipped with an automatic oil lubrication system with a toothed wheel drive. It automatically supplies the bar and the chain with the right quantity of oil. The moment the engine is accelerated, the oil also starts to flow through the bar plate more quickly as well.
The chain lubrication system has been set to its perfect adjustment at the factory. If it requires adjusting, take the saw to your nearest authorised after-sales service outlet.

A setting screw for adjusting the chain lubrication
(Fig. 37/ Item A) is located on the underside of the chain saw. Turning the screw counterclockwise increases the chain lubrication, turning it clockwise decreases the chain lubrication.
To check the chain lubrication, hold the chain saw, with the chain, over a piece of paper and run it at full speed for a few seconds. You will be able to judge the set amount of oil from the paper.
Chain maintenance
Chain sharpening
Chain sharpening requires special tools to ensure that cutters are sharpened at the correct angle and depth. For the inexperienced chain saw user, we recommend that the saw chain be professionally sharpened by the nearest professional Service Centre. If you feel comfortable sharpening your own saw chain, special tools are available from the professional
Service Centre.
Chain sharpening (Fig. 38)
Always sharpen the cutters only with outward strokes (Fig. 38) observing the values given in Fig.
39. After sharpening, the cutting links must all have the same width and length.
Warning: A sharp chain produces welldefined chips. When your chain starts to produce sawdust, it is time to sharpen. After the blades have been sharpened 3-4 times, check the height of the depth limiter and if necessary lower it with a flat file and then round off the front corner (Fig. 40).

Ordering replacement parts
Please quote the following data when ordering replacement parts: n Type of machine QG-PC 4645 n Article number of the machine 4501397 n Identification number of the machine 11010 n Replacement part number of the part required
Chain tension
Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar, but loose enough to be pulled around by hand.
Breaking in a new saw chain
A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the breakin period, and the interval between future adjustments will begin to lengthen quickly.
Warning: Never have more than 3 links removed from a loop of chain. This could cause damage to the sprocket. If in doubt please call the customer helpline.
Chain lubrication
Always make sure the automatic oiler system is working properly. Keep the oil tank filled with chain, bar and sprocket oil. Adequate lubrication of the bar and chain during cutting operations is essential to minimise friction with the guide bar. Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar discolouration.

Storage
Caution: Never put a chain saw into storage for longer than 30 days without carrying out the following steps.
Storing a chain saw
Storing a chain saw for longer than 30 days requires storage maintenance. Unless the storage instructions are followed, fuel remaining in the carburettor will evaporate, leaving gumlike deposits. This could lead to difficult starting and result in costly repairs.
1. Remove the fuel tank cap slowly to release any pressure in tank. Carefully drain the fuel tank.
2. Start the engine and let it run until the unit stops to remove fuel from carburettor.
3. Allow the engine to cool (approx. 5 minutes).
4. Remove the spark plug.
5. Pour 1 teaspoon of clean 2-cycle oil into the combustion chamber. Pull starter rope slowly several times to coat internal components.
Replace spark plug (Fig. 41).
Note: Store the unit in a dry place and away from possible sources of ignition such as a furnace, gas hot water heater, gas dryer, etc.
Putting the saw back into operation
1. Remove spark plug.
2. Pull starter rope briskly to clear excess oil from combustion chamber.
3. Clean the spark plug and check that the electrode gap (approx 0.6mm) is correct.
4. Prepare unit for operation.
5. Fill fuel tank with proper fuel/oil mixture.
