Safety precautions for chain saw operators Additional safety precautions While operating the chain saw please observe the following rules: a) Contact of the guide bar nose with any object should be avoided. b) Tip contact may cause the guide bar to move suddenly upward and backward, which may cause serious or fatal injury. c) Always operate the chain saw with both hands. The following additional safety precautions should be observed by all users of chain saws: 1.
General Safety Precautions max. CKA 45O The use of any chain saw may be hazardous. At full throttle chain speed can reach 45 mph (20 m/s). It is important that you read; fully understand and observe the following safety precautions and warnings. Read the owner’s manual and the safety instructions periodically. Maximum Computed Kickback Angle (CKA)* without using the chain brake when using the recommended bar and chain combinations (In this example the CKA is 45°). max.
Proper clothing The saw Clothing must be sturdy and snug-fitting, but allow complete freedom of movement. Avoid loose-fitting jackets, scarfs, neckties, jewelry, flared or cuffed pants, or anything that could become entangled with the saw or brush. Wear overalls or jeans with a reinforced cutting resistant insert (fig. 3). Parts of the chain saw: illustrations and description of parts see page 16. Protect your hands with gloves when handling saw and saw chain.
Chain saw operating instructions For assembly follow the procedure in the appropriate section "Mounting Guide Bar and Chain" of this manual. MAKITA chain, guide bar and sprocket must match each other (see the appropriate section in this manual). WARNING! Proper tension of the chain is extremely important. In order to avoid false setting the tensioning procedure must be followed as described in this manual.
Important adjustments WARNING! At correct idle speed, chain should not turn. For directions to adjust idle speed, see the appropriate section of this instruction manual. Do not use a saw with incorrect idle speed adjustment. Adjust the idle speed yourself according to the appropriate section of this manual. Wrap your fingers tightly around the handles, keeping the handles cradled between your thumb and forefinger (fig. 7).
In order to keep control of your saw, always maintain a firm foothold. Never work on a ladder, in a tree or on any other insecure support. Never use the saw above shoulder height (fig. 9). 10 Position the chain saw in such a way that your body is clear of the cutting attachment whenever the engine is running (fig. 10). Don’t put pressure on the saw when reaching the end of a cut.
Many factors influence the occurence and force of the kickback reaction. The type of bar and saw chain you use is a factor in the force of the kickback reaction. The speed of contact at which the cutter contacts the object. Kickback force increase with the rate of impact. The contact angle between the nose of the bar and the foreign object (fig. 11). Kickback is most pronounced in the upper quadrant of the bar nose. MAKITA chain types are designed to reduce kickback forces.
Pushback: To avoid pull-in Pushback occurs when the chain on the top of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the chain drives the saw straight back toward the operator causing loss of saw control. Pushback frequently occurs when the top of the bar is used for cutting (fig. 14). 1. Always start a cut with the chain rotating at full speed and the spike bar in contact with the wood. 2.
45° 2 12 First cut 45° Second cut = cutting down area 20 17 When felling, maintain a distance of at least 2 1/2 tree lengths from the nearest person (see fig. 17). If the tree has large buttress roots, cut into the largest buttresses vertically first (horizontally next) and remove (fig. 20). Note: The noise of your engine may drown any warning call.
Begin the felling cut slighty higher than the felling notch and on the opposite side of the tree (fig. 22). Then cut horizontally through towards the felling notch. Apply the chain saw with its spikes directly behind the uncut portion of wood and cut toward the notch (fig. 23). Leave approximately 1/10 of the tree diameter uncut! This is the hinge (fig. 23). Do not cut through the hinge because you could lose control of the direction of the fall.
Bucking 3 Bucking is cutting a log into sections. 2 1 29 WARNING! There is an extreme danger of kickback at this point. Extra caution must be taken to maintain control of the saw. To make the felling cut, follow the sectioning method described previously (fig. 29). If you are inexperienced with a chain saw plunge-cutting should not be attempted. Seek the help of a professional. 31 WARNING! 1. When bucking, do not stand on the log. Make sure the log will not roll down-hill.
Maintenance and Repair Never operate a chain saw that is damaged, improperly adjusted or not completely or securely assembled. Follow the maintenance and repair instructions in the appropriate section of this manual. 1. Relieving cut Pressure side Tension side 2. Cross cut WARNING ! 33 2. Cross cut Always stop the engine and make sure that the chain is stopped before commencing any maintenance or repair work or cleaning the saw.

PUTTING INTO OPERATION STOP Mounting the guide bar and saw chain Use the universal wrench delivered with the chain saw for the following work. Put the chain saw on a stable surface and carry out the following steps for mounting the guide bar and chain: CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see "Replacing the spark plug").
4 13 G - H Turn the chain tightener (C/6) to the right (clockwise) until the chain engages the guide groove of the bottom side of the bar (see circle). Press the guide bar against the housing with your left hand.
Safety chain brake 2 1 3 B A The models DCS 340/DCS 341/DCS 400 and DCS 401 comes with an inertia chain brake as standard equipment. The chain brake will automatically stop the chain if the kickback is sufficiently strong, which is caused by the tip contacting wood while the saw is running (see "SAFETY PRECAUTIONS", page 9). The chain will stop within a fraction of a second. The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergency.
We recommend the use of chain oil which is bio-degradable in order to protect the environment. The use of bio-degradable oil may even be required by local regulations. Refuelling The chain oil BIOTOP sold by MAKITA is made of special vegetable oils and is 100% bio-degradable. BIOTOP has been granted the "blue angel" (Blauer Umweltschutz-Engel) for being particularly environment-friendly (RAL UZ 48).
To ensure troublefree operation of the oil pump the oil guide groove at the crank case (I/3) and the oil inlet bore in the guide bar (I/4) must be cleaned regularly. 3 Note: After the saw has been turned off it is normal for residual chain oil to drip from the oil feed system, the guide bar and the chain for a time. This does not constitute a defect! Place the saw on a suitable surface.
Checking the chain lubrication Checking the safety chain brake 6 M N Do not work with the saw without first checking the chain brake! - Start the engine as described (make sure you have a good footing, and place the saw on the ground in such a way that the blade is free of contact). - Grasp the tubular handle firmly with one hand and hold the grip with the other.
Working in winter normal operation 2 subfreezing operation 1 3 A B In order to prevent carburetor icing in conditions of low temperature combined with high humidity, and in order to get up to operating temperature faster in subfreezing temperatures, heated air can be taken from the cylinder (marking (circled) on insert in "snowflake" position). At temperatures above freezing the carburetor must NOT be fed heated air (marking (circled) on insert in "sun" position).
E - - F All cutters must be sharpened to the same angle, 30°. Different angles result in a roughly, irregularly running chain, increase wear and tear and cause chain breakage. The 85° front rake of the cutter results from the cut depth of the round file. If the proper file is used in the right manner, the correct front rake will be obtained automatically. Files and how to work with them - Use a special round file for chains (dia. 4 mm) for sharpening the chain.
Cleaning the brake band and sprocket interior Replacing the saw chain CAUTION: STOP Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)! 6 2 1 2 3 7 4 A 5 C 1 D CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see "Replacing the spark plug"). Always wear protective gloves! Check the sprocket (C/1) before mounting a new chain.
Cleaning the air filter 3 2 STOP E - F 1 - Remove the filter cover (E/1) (2 screws). CAUTION: Grasp the top and bottom sections of the air filter as shown in figure F and pull apart. Press the choke (E/2) up to shut the choke valve and to prevent dirt particles from entering the carburetor. CAUTION: To prevent injury to the eyes, do NOT blow out dirt particles! - Pull the air filter (E/3) off the carburetor. Do not use fuel to clean the air filter. - Cover the carburetor with a clean cloth.
