GENERAL SAFETY RULES
WARNING:
The warnings, labels and instructions found in this section of the operator’s manual are for your safety. Failure to follow all instructions may result in serious personal injury.
Safe operation of this tool requires that you read and understand this operator’s manual and all labels affixed to the tool. Safety is a combination of using common sense, staying alert, and knowing how your saw works.
READ ALL INSTRUCTIONS
■■
KNOW YOUR TOOL. Read the operator’s manual carefully.
■■
Learn the saw’s applications and limitations as well as the specific potential hazards related to this tool.
■■
CHAINSAWS are designed for cutting wood only .
■■
■■
KICK-BACK 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. Tip contact in some cases 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 ma y cause you to lose control of the saw, which could result in serious personal injury. DO NOT rely exclusiv ely upon the safety devices built into your saw. As a chainsaw user, y ou should take several steps to keep cutting jobs free from accident or injury .
1. With a basic understanding of kick-back, 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 when the engine is running. Place your right hand on the rear handle and your left hand on the front handle, with thumbs and fingers encircling the chainsaw handles. A firm grip together with a stiff left arm will help maintain control of the saw if kick-back occurs.
3. Make sure the area in which you are cutting is free from obstructions. DO NOT let the nose of the guide bar contact a log, branch, fence or any other obstruction which could be hit while you are operating the saw.
4. Cut at high engine speeds. Always cut with the engine running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed.
5. Do not overreach or cut above chest height.
6. Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
7. Only use replacement bars and chains specified by the manufacturer or the equivalent.
■■
DO NOT OPERATE A CHAINSAW WITH ONE HAND.
■■
Serious injury to the operator, helpers and/or bystanders may result from one-handed operation. A chainsaw is intended for two-handed use.
■■
DO NOT OPERATE A CHAINSAW WHEN YOU ARE
■■
FATIGUED. Never oper ate a chainsaw when you are tired or under the influence of medication, drugs or alcohol.
■■
USE SAFETY FOOTWEAR. Wear snug-fitting clothing,
■■
protective gloves and eye, hearing and head protection devices.
■■
DO NOT STAND ON ANY UNSTABLE SURFACE while
■■
using your chainsaw. This includes ladders, scaff olding, trees etc.
■■
USE CAUTION WHEN HANDLING FUEL. Move the
■■
chainsaw at least 15 m (50 feet) from the refuelling point before starting the engine.
■■
DO NOT ALLOW OTHER PERSONS to be near the
■■
chainsaw when starting or cutting with the chainsaw . Keep bystanders and animals out of the w ork area.
■■
DO NOT START CUTTING until you have a clear w ork
■■
area, secure footing and a planned retreat path from the falling tree.

Fig. 1
NOTE: Your chainsaw has been fully factory tested. It is normal to find some slight oil residue on the saw.
MAINTENANCE PRECAUTIONS
Never operate a chainsaw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released. If the saw chain moves at idling speed, the carburettor may need adjusting. Refer to “Operation-Adjusting Idling Speed” later in this manual. If the saw chain still moves at idling speed after adjustment has been made, contact a Homelite service dealer for adjustment and discontinue use until the repair is made.
WARNING:
All chainsaw service, other than items in the operator’s manual maintenance instructions, should be performed by competent chainsaw service personnel. If improper tools are used to remove the flywheel or clutch, or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel may occur and subsequently cause the flywheel to burst with possible serious injury.
KICK-BACK
Kick-back is a dangerous reaction that can lead to serious injury . Do not rely only on the safety devices provided with your saw. As a chainsaw user, you must take special safety precautions to help keep cutting jobs free from accident or injury .
NOTE: Refer to “Operation” later in this manual for added information on kick-back and how to avoid serious personal injury .

Users, such as professional loggers who need to draw the tip through the cut, make boring cuts, or cut logs bigger than the bar length, should reinstall the SAFE-T-TIP as soon as those cuts are complete. When cutting without the SAFE-T-TIP, the user must use proper techniques as sho wn in the manual to avoid kick-back.
NOTE: Refer to “Maintenance” later in this manual for instructions on reinstalling the SAFE-T-TIP nose guard.
LOW KICK-BACK SAW CHAIN
The rakers (depth gauges) ahead of each cutter can minimise the force of a kick-back reaction by preventing the cutters from digging in too deeply at the kick-back zone. Only use replacement chain which is equivalent to the original chain or has been certified as a low kick-back chain.
As saw chains are sharpened, they lose some of the low kick-back qualities and extra caution is required.
WARNING:
The warnings and instructions in this section of the operator’s manual are for your safety and to prevent serious personal injury.
UNDERSTANDING YOUR CHAINSAW SAFETY DEVICES
SAFE-T-TIP ANTI-KICK-BACK NOSE GUARD
See Figure 4.
The SAFE-T-TIP prevents kick-back because it covers the tip of the bar where rotational kick-back is generated. Inexperienced persons should never attempt to cut when the SAFE-T-TIP has been removed from the bar tip .
GUIDE BARS
Generally, guide bars with small radius tips have somewhat lower kick-back potentials.
When making a replacement, be sure to order one of the Homelite bars listed for your saw in this operator’s manual. The proper size SAFE-T-TIP nose guard comes installed on the bar. Use only guide bars which have a provision f or mounting the SAFE-T-TIP.
UK - Page 10
Page 11
OPERATION
CHAIN BRAKE
Chain brakes are designed to quickly stop the chain from rotating. When the chain brake lever/hand guard is pushed towards the bar, the chain should stop immediately. A chain brake does not prevent kick-back.
The chain brake should be cleaned and tested daily. Refer to “Operation” later in this manual for additional information.
WARNING:
Even with daily cleaning of the mechanism, the dependability of a chain brake to perform under field conditions cannot be certified. Keep the SAFE-T-TIP nose guard on the saw guide bar and use proper cutting techniques.
RUN POSITION
WARNING:
KICK-BACK occurs when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper portion of the tip of the guide bar may cause the chain to dig into the object and stop the chain for an instant. The result is a lightning-fast, reverse reaction which kicks the guide bar up and back towards the operator. If the saw chain is pinched along the top of the guide bar, the guide bar can be driven rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious injury.
Do not rely exclusively on the safety devices built into the saw. As a chainsaw user, you should take several steps to keep your cutting jobs free from accident or injury.
KICK-BACK PRECAUTIONS
Rotational kick-back occurs when the moving chain contacts an object at the Kick-bac k Danger Zone of the guide bar . The result is a lightning-fast, reverse reaction which kicks the guide bar up and back towards the operator . This reaction can cause loss of control which may result in serious injury.

FUEL AND REFUELLING
HANDLING THE FUEL SAFELY
■■
Mix 2% oil into the petrol. This is a 50:1 ratio.
■■
■■
Mix the fuel thoroughly and each time before refuelling.
■■
■■
Mix in small quantities. Do not mix quantities larger than
■■
usable in a 30-day period. A 2-cycle oil containing a fuel stabiliser is recommended.
WARNING:
Check for fuel leaks. If any are found, correct them before using the saw to prevent fire or burn injury.
■■
Always handle fuel with care; it is highly flammable.
■■
■■
Always refuel outdoors and do not inhale fuel vapour.
■■
■■
Do not let petrol or oil come in contact with skin.
■■
■■
Keep petrol and oil away from the eyes. If petrol or oil
■■
comes in contact with the eyes, wash them immediately with clean water. If irritation is still present, see a doctor immediately.
■■
Clean up spilled fuel immediately.
■■
MIXING THE FUEL
■■
This product is powered by a 2-cycle engine and requires
■■
pre-mixing petrol and 2-cycle oil. Pre-mix unleaded petrol and 2-cycle engine oil in a clean container approved for petrol.
■■
This engine is certified to operate on unleaded petrol
■■
intended for motor vehicle use with an octane rating of 87 ([R + M] / 2) or higher.
■■
Do not use any type of pre-mixed petrol/oil from fuel
■■
service stations. This includes the pre-mixed petrol/oil intended for use in mopeds, motorcycles etc.
■■
Use a high quality 2-cycle self-mixing oil for air-cooled
■■
engines. Do not use motor vehicle oil or 2-cycle outboard oil.
FILLING THE TANK

PREPARING FOR CUTTING
PROPER GRIP ON HANDLES
See Figures 20 and 21.
Refer to “Specific Safety Rules – Safety Apparel” earlier in this manual for appropriate safety equipment.
■■
Wear non-slip gloves for maximum grip and protection.
■■
■■
Hold the saw firmly with both hands. Always keep your
■■
LEFT HAND on the front handle and your RIGHT HAND on the rear handle so that your body is to the left of the chain line.
WARNING:
Never use a left-handed (cross-handed) grip or any stance that would place your body or arm across the chain line.
■■
Maintain a proper grip on the saw whenever the engine is
■■
running. The fingers should encircle the handle and the thumb be wrapped under the handlebar. This grip is least likely to be broken (by a kick-back or other sudden reaction of the saw). Any grip in which the thumb and fingers are on the same side of the handle is dangerous because a slight kick of the saw can cause loss of control.
CHAIN LINE
WARNING:
DO NOT operate the throttle trigger with your left hand and hold the front handle with your right hand. Never allow any part of your body to be in the chain line while operating a saw.
PROPER CUTTING STANCE

OPERATION
BASIC OPERATING/CUTTING PROCEDURES
Practise cutting a few small logs, using the following technique to get the “feel” of using the saw before you begin a major sawing operation.
1. Take the proper stance in front of the wood with the
saw idling.
2. Accelerate the engine to full throttle just before entering
the cut by squeezing the throttle trigger.
3. Begin cutting with the saw against the log.
4. Keep the engine at full throttle the entire time y ou
are cutting.
5. Allow the chain to cut for y ou; exert only light downward
pressure. Forcing the cut could result in damage to the bar, chain or engine .
6. Release the throttle trigger as soon as the cut is completed,
allowing the engine to idle. Running the saw at full throttle without a cutting load may result in unnecessary wear to the chain, bar and engine.
7. Do not put pressure on the saw at the end of the cut.
WORK AREA PRECAUTIONS
■■
Cut only wood or materials made from wood; no sheet
■■
metal, no plastics, no masonry , no non-wood building materials.
■■
Never allo w children to operate y our saw. Allow no
■■

OPERATION
ADJUSTING IDLING SPEED
■■
If the engine starts, runs, and accelerates but will not idle,
■■
turn the idling speed screw “T” clockwise to increase idling speed.
■■
If the chain turns at idle, turn the idling speed screw “T
■■
anticlockwise to reduce the idling RPM and stop the chain movement. If the saw chain still moves at idling speed, contact a Homelite service dealer for adjustment and discontinue use until the repair is made.
WARNING:
THE SAW CHAIN SHOULD NEVER TURN AT IDLE. Turn the idling speed screw “T” anticlockwise to reduce the idling RPM and stop the chain, or contact a Homelite service dealer for adjustment and discontinue use until the repair is made.
Serious personal injury may result from the saw chain turning at idle.
OPERATING THE CHAIN BRAKE
Refer to “Safety” earlier in this manual for additional information.
Check the operating condition of the chain brake before each use.
1. Start the engine and grasp the front and rear handles securely with both hands.
2. Pull the throttle trigger to bring the chainsaw up to full speed. Using the back of your left hand, engage the chain brake by pushing the chain brake lever/hand guard towards the bar while the chain is rotating rapidly.
See Figure 27.
NOTE: The chain brake should engage and stop the chain immediately. If not, stop the saw b y placing the ignition switch in the “O” stop position. Take the saw to a Homelite service dealer for repair and discontinue use until the repair is made.
3. Reset the chain brake back into the RUN position by grasping the right-hand side (from operator’s position) of the chain brake lever/hand guard and pull towards the front handle until you hear a click. See Figure 28.

FELLING TREES HAZARDOUS CONDITIONS
See Figure 29.
WARNING:
OPERATION
STAY AWAY FROM
ELECTRICAL LINES
AND BUILDINGS
Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended.
When felling a tree, it is important that you heed the following warnings to pre vent possible serious injury .
■■
Wear eye, hearing and head protection when operating
■■
this equipment.
■■
Do not cut down trees having an extreme lean or large
■■
trees with rotten or dead limbs, loose bark or hollow trunks. Have these trees pushed or dragged down with heavy equipment, then cut them up.
■■
Consider the distribution and weight of heavy limbs.
■■
■■
Clear out the underbrush around the tree to be felled.
■■
Do not cut trees near electrical wires or buildings.
■■
Consider the direction in which the tree leans.
■■
Check the tree for damaged or dead branches which
could fall and hit you during felling.
Periodically glance at the top of the tree during the
back-cut to assure the tree is going to fall in the desired direction.
■■
Keep all bystanders at a safe distance (at least twice
■■
the height of the tree).
Prepare a path of safe retreat.
If the tree starts to fall in the wrong direction, or if the
saw gets caught or hung up during the fall, leave the saw and save yourself!
■■
Consider the wind direction before felling a tree.
■■
■■
Do not fell trees near power lines or near buildings which
■■
could be struck by falling limbs or the tree itself.
The chainsaw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.
Remove dirt, stones, loose bark, nails, staples and wire from the tree where felling cuts are to be made.

OPERATION
PROPER PROCEDURE FOR TREE FELLING
See Figure 30.
1. Pick your escape route (or routes in case the intended route is blocked). Clear the immediate area round the tree and make sure there are no obstructions in your planned path of retreat. Clear the path of safe retreat approximately 135° from the planned line of fall.
2. Consider the force and direction of the wind, the lean and balance of the tree, and the location of large limbs. These things influence the direction in which the tree will fall. Do not try to fell a tree along a line different from its natural line of fall.

OPERATION
3. Cut a notch about one-third the diameter of the trunk in
the side of the tree. Make the notch cuts so they intersect at right angles to the line of fall. This notch should be cleaned out to leave a straight line. To keep the weight of the wood off the saw, always make the lower cut of the notch before the upper cut. See Figure†31.
4. Make the back-cut level and horizontal, and at a minimum of 5 cm (2 in.) above the horizontal cut of the notch.
See Figure 31.
NOTE: Never cut through to the notch. Always leave a band of wood between the notch and back cut (approximately 5 cm (2 in .) or one-tenth the diameter of the tree). This is called “hinge” or “hinge wood”. It controls the fall of the tree and prevents slipping or twisting or shoot-back of the tree off the stump. See Figure 32.
On large diameter trees, stop the back cut before it is deep enough for the tree to either fall or settle back on the stump. Then insert soft wooden or plastic wedges into the cut so they do not touch the chain. Drive wedges in, little by little, to help jack the tree over.
See Figure 33.
When bucking or felling with a wedge, it may be necessary to remove the SAFE-T-TIP anti-kick-back device to allow the bar to be drawn through the cut. After you complete the cut, reinstall the tip immediately.
5. As tree starts to fall, stop the chainsaw and put it down immediately. Retreat along the cleared path, but watch the action in case something falls your way.

OPERATION
REMOVING BUTTRESS ROOTS
A buttress root is a large root extending from the trunk of the tree above the ground. Remove large buttress roots before felling. Make the horizontal cut into the buttress first, followed by the vertical cut. Remove the resulting loose section from the work area. Follow the correct tree felling procedure after you have removed the large buttress roots. Refer to “Operation – Proper Procedure for T ree Fe lling” earlier in this manual.
BUCKING
Bucking is the term used for cutting a fallen tree to the desired log length.
■■
Cut only one log at a time.
■■
■■
Support small logs on a saw horse or another log while
■■
bucking.
■■
Keep a clear cutting area. Make sure that no objects
■■
can contact the guide bar nose and chain during cutting; this can cause kick-back. To avoid the danger, keep the SAFE-T-TIP anti-kick-back device attached while cutting. Refer to “Safety – Kick-back” earlier in this manual.
■■
During bucking operations, stand on the uphill side so
■■
that the cut-off section of the log cannot roll over you.
■■
Sometimes it is impossible to avoid pinching (with just
■■
standard cutting techniques) or difficult to predict which way a log will settle when cut.

BUCKING WITH A WEDGE
If the wood diameter is large enough for you to insert a soft bucking wedge without touching the chain, you should use the wedge to hold the cut open to prevent pinching.
NOTE: When b ucking or felling with a w edge, you ma y need to remove the SAFE-T-TIP anti-kick-back device to allow the bar to be drawn through the cut. After you complete the cut, reinstall the tip.

OPERATION
BUCKING LOGS UNDER STRESS
Make the first bucking cut one-third of the way through the log and finish with a two-thirds cut on the opposite side. As you cut the log, it will tend to bend. The sa w can become pinched or hung in the log if you make the first cut deeper than one-third of the diameter of the log.
Give special attention to logs under stress to prevent the bar and chain from pinching.
OVERBUCKING
See Figure 38.
Begin on the top side of the log with the bottom of the saw against the log; exert light pressure downward. Note that the saw will tend to pull away from you.
UNDERBUCKING
See Figure 38.
Begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During underbucking, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control.

LIMBING AND PRUNING
See Figure 39.
Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance.
Keep the tree between you and the chain while limbing. Cut from the side of the tree opposite the branch you are cutting.
Do not cut from a ladder: this is extremely dangerous. Leave this operation for professionals.
Do not cut above chest height, as a saw held higher is difficult to control against kick-back.

WARNING:
Never climb into a tree to limb or prune. Do not stand on ladders, platforms, a log or in any position which may cause you to lose your balance or control of the saw.
When pruning trees it is important not to make the flush cut next to the main limb or trunk until you have cut off the limb further out to reduce the weight. This prevents stripping the bark from the main member.
1. Underbuck the branch one-third through for your first cut.
2. Overbuck the branch to drop it.
3. Finish by cutting smoothly and neatly against the main
member so the bark will grow back to seal the wound.
WARNING:
If the limbs to be pruned are above chest height, hire a professional to perform the pruning.
CUTTING SPRING POLES
See Figure 40.
A spring pole is any log, branch, rooted stump or sapling bent under tension by other wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stump. Watch out f or spring poles; the y are dangerous.

ADJUSTING THE CHAIN TENSION
See Figures 52, 53 and 54.
WARNING:
Never touch or adjust the chain while the motor is running. The saw chain is very sharp. Always wear protective gloves when performing maintenance on the chain.
1. Stop the engine before setting the chain tension.
2. Make sure the guide bar nuts are loosened to finger-tight
and turn the chain tensioner clockwise to tension the chain.
NOTE: A cold chain is correctly tensioned when there is no slack on the underside of the guide bar, the chain is snug and it can be turned by hand without binding.
3. Re-tension the chain whenever the flats on the drive links hang out of the bar groove.
NOTE: During normal saw operation, the temperature of the chain increases. The drive links of a correctly tensioned warm chain will hang approximately 1.25 mm (0.050 in.) out of the bar groove. To help determine the correct warm chain tension, the tip of the combination wrench can be used as a guide.
NOTE: New chain tends to stretch. Check the chain tension frequently and tension as required.
CAUTION:
A chain tensioned while warm may be too tight on cooling. Check the “cold tension” before next use.

CHAIN MAINTENANCE
CAUTION:
Check that the switch is in the STOP “ ” position before working on the saw .
Use only a low-kick-back chain on this saw. This fast-cutting chain provides kick-back reduction when properly maintained.
For smooth and fast cutting, maintain the chain properly. The chain requires sharpening when the wood chips are
small and powdery , the chain must be f orced through the wood during cutting, or the chain cuts to one side. During maintenance of the chain, consider the following:
■■
Improper filing angle of the side plate increases the risk
■■
of a severe kick-back.

MAINTENANCE
Raker (depth gauge) clearance. See Figure 55.
1. Too low increases the potential for kick-back.
2. Not low enough decreases cutting ability.
If the cutter teeth hit hard objects such as nails and stones, or are abraded by mud or sand on the wood, let the Homelite service dealer sharpen the chain.
NOTE: Inspect the drive sprocket for wear or damage when replacing the chain. If signs of wear or damage are present in the areas indicated, have the drive sprocket replaced by a Homelite service dealer. See Figure 56.

MAINTAINING THE SAFE-T-TIP NOSE GUARD
See Figures 69 and 70.
CAUTION:
Make sure the chain has stopped before you do any work on the saw.
Fig. 67
WARNING:
Although the guide bar comes with a SAFE-T-TIP anti­kick-back device already installed, you need to check the tightness of the mounting screw before each use.
Make sure the chain has stopped before you do any work on the saw.
Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar life. The bar should be cleaned every day of use and checked for wear and damage.
Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a file as soon as they occur.
A bar with any of the following faults should be replaced:
Wear inside the bar rails which permits the chain to lie over sideways
Bent guide bar
Cracked or broken rails
Spread rails
In addition, lubricate guide bars (with a sprocket at their tip) weekly . Using a grease syringe, lubricate weekly in the lubricating hole.
T urn the guide bar and check that the lubrication holes and chain groove are free from impurities.
Tighten the mounting screw of the nose guard as instructed below . These are specially hardened screws . If you cannot install the screw tightly, replace both the screw and the SAFE-T-TIP before further operation. Do not replace the screw with an ordinary screw .
In addition to preventing chain contact with solid objects at the nose of the bar, the SAFE-T-TIP also helps k eep the chain away from abrasive surfaces, such as the ground. Keep it on the right-hand side of the bar where it will be between the chain and the ground during flush with ground cutting.
The mounting screw requires a 5/16 in. spanner (or adjustable spanner) to achieve the recommended tightness of 4-5 Nm (35 - 45 in. lb.). A tightness within this range can be achieved by using the following method.
1. Tighten the screw with your finger.
2. Tighten the screw an additional three-quarters of a turn
using a spanner.
