Fuels / Refuelling
-Stop the engine before refuelling the chain saw.
-Do not smoke or work near open fires (5).
-Let the engine cool down before refuelling.
-Fuels can contain substances similar to solvents. Eyes and skin should not come in contact with mineral oil products. Always wear protective gloves when refuelling. Frequently clean and change protective clothes. Do not breathe in fuel vapors. Inhalation of fuel vapours can be hazardous to your health.
-Do not spill fuel or chain oil. When you have spilt fuel or oil immediately clean the chain saw. Fuel should not come in contact with clothes. If your clothes have come in contact with fuel, change them ot once.
-Ensure that no fuel or chain oil oozes into the soil (environmental protection). Use an appropriate base.
-Refuelling is not allowed in closed rooms. Fuel vapors will accumulate near the floor (explosion hazard).
-Ensure to firmly tighten the screw caps of the fuel and oil tanks.
-Change the place before starting the engine (at least 3 m from the place of refuelling) (6).
-Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in the near future.
-Use only approved and marked containers for the transport and storage of fuel and chain oil. Ensure children have no access to fuel or chain oil.
Putting into operation
- Do not work on your own. There must be someone around in case of an emergency (within shouting distance).
- Ensure that there are no children or other people within the working area. Pay attention to any animals in the working area, as well
(7).
- Before starting work the chain saw must be checked for perfect function and operating safety according to the prescriptions.
Checkespeciallythefunctionofthechainbrake,thecorrectmounting of the guide bar, the correct sharpening and tightening of the chain, the firm mounting of the sprocket guard, the easy motion of the throttle lever and the function of the throttle lever lock, the cleanliness and dryness of the handles, and the function of the ON/OFF switch.
- Start the chain saw only after complete assembly and inspection. Operation of the device is only permitted after all the appropriate accessories are attached!
- Before starting the chain saw ensure that you have a safe footing.
- Put the chain saw into operation only as described in this instruction manual (8). Other starting methods are not allowed.
- When starting the chain saw it must be well supported and securely held. The guide bar and chain must not be in contact with any object.
- When working with the chain saw always hold it with both hands. Take the back handle with the right hand and the tubular handle with the left hand. Hold the handles tightly with your thumbs facing your fingers.
- CAUTION: When releasing the throttle lever the chain will keep on running for a short period of time (free-wheeling).
- Continuously ensure that you have a safe footing.
- Hold the chain saw such that you will not breathe in the exhaust gas. Do not work in closed rooms (danger of poisoning).
- Switch off the chain saw immediately if you observe any changes in its operating behavior.
- The engine must be switched off before checking the chain tension,tighteningthechain,replacingitorclearingmalfunctions (9).
- Whenthesawingdeviceishitbystones,nailsorotherhardobjects, switch off the engine immediately and check the sawing device.
- When stopping work or leaving the working place switch off the chain saw (9) and put it down such that nobody is endangered.
- Do not put the overheated power chain saw in dry grass or on any inflammable objects. The muffler is very hot (danger of fire).

Kickback
-When working with the chain saw dangerous kickbacks may occur.
-Kickback occurs when the upper part of the end of the guide bar inadvertently touches wood or other hard objects (10).
-This causes the saw to be thrown back toward the user with great force and out of control. Risk of injury!
In order to prevent kickback, follow these rules:
-Only specially trained persons should perform plunge cuts, i.e., piercing timber or wood with the tip of the saw!
-Always observe the end of the guide bar. Be careful when continuing an already started cut.
-When starting to cut the chain must be running.
-Ensure that the chain is always sharpened correctly. Pay special attention to the height of the depth limiter.
-Never cut several branches at the same time. When cutting a branch ensure that no other branch is touched.
-When crosscutting a trunk be aware of the trunks next to it.
Working behavior/Method of working
-Only use the chain saw during good light and visibility periods. Be aware of slippery or wet areas, and of ice and snow (risk of slipping). The risk of slipping is extremely high when working on recently peeled wood (bark).
-Never work on unstable surfaces. Make sure that there are no obstacles in the working area, risk of stumbling. Always ensure that you have a safe footing.
-Never saw above your shoulder height (11).
-Never saw while standing on a ladder (11).
-Never climb up into trees to perform sawing with the chain saw.
Do not work leaning too far over.
-Guide the chain saw in such a way that no part of your body is within the elongated swivelling range of the saw (12).
-Use the chain saw for sawing wood only.
-Avoid touching the ground with the chain saw while it is still running.
-Never use the chain saw for lifting up or removing pieces of wood or other objects.
-Remove foreign objects such as sand, stones and nails found within the working area. Foreign objects may damage the sawing device and can cause dangerous kickback.
-When sawing precut timber use a safe support (sawing jack, 13). Do not steady the workpiece with your foot, and do not allow anyone else to hold or steady it.
Secure round pieces against rotation.
-For cutting down trees or performing crosscuts the spike bar (13, Z) must be applied to the wood to be cut.
-Before performing a crosscut firmly apply the spike bar to the timber, only then can the timber be cut with the chain running. For this the chain saw is lifted at the back handle and guided with the tubular handle. The spike bar serves as a centre of rotation. Continue by slightly pressing down the tubular handle and simultaneously pulling back the chain saw. Apply the spike bar a little bit deeper and once again lift the back handle.
-When the timber must be pierced for cutting or longitudinal cuts are to be performed it is urgently recommended to have this carried out by specially trained persons only
(high risk of kickback).
Do longitudinal lengthwise cuts at the lowest possible angle (14). Be very careful when doing this type of cut, as the spike bar cannot grip.
-The saw must be running whenever you remove the chain saw from the wood.
-When performing several cuts the throttle lever must be released in between.

-Be careful when cutting splintery wood. Cut pieces of wood may be pulled along (risk of injuries).
-When cutting with the upper edge of the guide bar, the chain saw may be pushed in the direction of the user if the chain gets clamped. For this reason use the lower edge of the bar whenever possible. The chain saw will then be pushed away from you (15).
-If the timber is under tension (16), first cut the pressure side
(A). Then the crosscut can be performed on the tension side
(B). Thus clamping of the guide bar can be avoided.
CAUTION: People felling trees or cutting of branches must be specially trained. High risk of injuries!
-When cutting of branches, the chain saw should be supported on the trunk. Do not use the end of the bar for cutting (risk of kickback).
-Be aware of branches under tension. Do not cut free branches from below.
-Never perform detensioning cuts while standing on the trunk.
-Before cutting down a tree ensure that
a)only those people are within the working area which are actually involved in cutting down the tree.
b)every worker involved can withdraw without stumbling (the people should withdraw backwards in a diagonal line, i. e. at a degree of 45°).
c)the bottom part of the trunk is free from foreign objects, underbrush and branches. Make sure to have a safe footing (risk of stumbling).
d)the next working place is at least 2 1/2 tree lengths away (17). Before cutting down the tree check the direction of fall and make sure that there are neither people nor objects within a distance of 2 1/2 tree lengths.
-Judging the tree:
Direction of hanging - loose or dry branches - height of the tree
-natural overhang - is the tree rotten?
-Take into account the direction and speed of the wind. If strong gusts are occurring, do not do any felling.
-Cutting the roots:
Start with the strongest root. First do the vertical and then the horizontal cut.
-Notching the trunk (18, A):
The notch determines the direction of fall and guides the tree. The trunk is notched perpendicular to the direction of fall and penetrates 1/3 -1/5 of the trunk diameter. Perform the cut near the ground.
-When correcting the cut, always do so over the whole width of the notch.
-Cut down the tree (19, B) above the bottom edge of the notch
(D). The cut must be exactly horizontal. The distance between both cuts must be approx. 1/10 of the trunk diameter.
-The material between both cuts (C) serves as a hinge. Never cut it through, otherwise the tree will fall without any control. Insert felling wedges in time.
-Secure the cut only with wedges made of plastic or aluminium. Do not use iron wedges. If the saw hits an iron wedge the chain can be seriously damaged or torn.
-When cutting down a tree always stay sidewards of the falling tree.
-When withdrawing after having performed the cut, be alert for falling branches.
-When working on sloping ground the user of the chain saw must stay above or sidewards of the trunk to be cut or the tree already cut down.
-Be alert for trunks which may roll towards you.

Transport and storage
-When changing your location during work switch off the chain saw and actuate the chain brake in order to prevent an inadvertent start of the chain.
-Never carry or transport the chain saw with the chain running.
-When transporting the chain saw over long distances the guide bar protection cover (delivered with the chain saw) must be applied.
-Carry the chain saw with the tubular handle. The guide bar pointsbackwards(20).Avoidcomingincontactwiththemuffler
(danger of burns).
-Ensure safe positioning of the chain saw during car trans portation to avoid fuel or chain oil leakage.
-Store the chain saw safely in a dry place. It must not be stored outdoors. Keep the chain saw out of reach of children.
-Before storing the chain saw over a long period of time or shipping it the fuel and oil tanks must be completely emptied.
Maintenance
-Before performing maintenance work switch off the chain saw (21) and pull out the plug cap.
-Before starting work always check the operating safety of the chain saw, in particular the function of the chain brake. Make sure that the chain is always sharpened and tightened correctly (22).
-Operate the chain saw only at a low noise and emission level. For this ensure the carburetor is adjusted correctly.
-Regularly clean the chain saw.
-Regularly check the tank cap for tightness.
Observe the accident prevention instructions issued by trade associations and insurance companies. Do not perform any modifications on the chain saw. You will put your safety at risk.
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 spare parts other than original MAKITA parts or accesories and guide bar/chain combinations or lengths which are not approved bring a high risk of accidents. We cannot accept any responsibility for accidents and damage resulting from using sawing devices or accesories which have not been approved.
