WARNING Fuel is highly fl ammable and its fumes should not be inhaled. Be particularly careful when handling the machine as the sparks produced when cutting metal can easily ignite any fuel spillage. Cutting safety ○ Keep bystanders at a safe distance, away from the work area. Anyone entering the work area must wear personal protective equipment. Flying fragments from the workpiece or the cut-off wheel may cause injury. Children, other unauthorized persons and animals must remain well away from the work area. ○ Hold the machine fi rmly with the right hand on the rear handle and the left hand on the front handle. ○ Keep fi rm footing and balance. Do not over-reach. ○ Keep all parts of your body away from the muffl er and cutting attachment when the engine is running. ○ Make sure to check the work area for any hidden hazards such as water or gas pipes, electrical cables and fl ammable substances. ○ Never place the machine on the ground when running. ○ Always ensure that the engine is shut off and any cutting attachments have completely stopped before clearing debris from the cutting attachment. ○ Always carry a fi rst-aid kit when operating any power equipment. ○ The muffl er gets very hot during and after use. This also applies during idling. Be aware of the fi re hazard, especially when working near fl ammable substances and/or vapours. WARNING ○ Exhaust gases from the engine are hot and may contain sparks which can cause a fi re. Also, sparks are generated when cutting metal with this machine. Never use the machine where fl ammable substances and gases are present. ○ Sparks generated from cutting operations can cause fi res. Always have adequate fi re extinguishing equipment available. ○ When relocating to a new work area, be sure to shut off the machine and ensure that all cutting attachments are stopped. ○ Always ensure that the engine is shut off and any cutting attachments have completely stopped before moving. Gyroscopic forces occur when moving while the engine is operating and the cut-off wheel is rotating. This may cause you to lose control of the machine. ○ Never cut materials that consist of asbestos. ○ Never leave the engine running while unattended (e.g. on the ground). Kickback and related warnings Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes sudden stalling of the rotating wheel which in turn causes the machine to be forced in the direction opposite of the wheel's rotation at the point of the binding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on the direction of the wheel's movement at the point of pinching. Abrasive wheels may also break under these conditions. Either of these reactions may cause you to lose control of the machine which could result in serious personal injury. Kickback is the result of cut-off machine misuse and/or incorrect operating procedures or conditions that can be avoided by taking proper precautions as given below. ○ Kickback occurs when the upper angle of the cut-off wheel is used or touches an object when the cut-off wheel is running. Pay special attention not to touch the upper angle of the cut-off wheel to any object. (Fig. 2, Fig. 3) ○ Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the cut-off wheel. Corners, sharp edges or bouncing have a tendency to snag the rotating wheel and cause loss of control or kickback. (Fig. 4) ○ Do not use cut-off wheels other than those approved or recommended by the manufacturer. Never use blades designed for cutting wood. Failure to comply could result in personal accidents or injury. ○ Do not jam the wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage. ○ If the wheel binds or a cut is interrupted for any reason, stop the engine and hold the machine motionless until the wheel comes to a complete stop. Never attempt to remove the wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding. ○ Do not restart the cutting operation with the wheel in the workpiece. After allowing the wheel to reach full speed, carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. ○ Provide supports for panels or any oversized workpiece to minimize risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece so that the cutting surface to open. (Fig. 5) Maintenance safety ○ Maintain the machine according to recommended procedures. ○ Disconnect the spark plug before performing maintenance except for carburetor adjustments. ○ Keep others away when making carburetor adjustments. ○ Use only genuine Tanaka replacement parts as recommended by the manufacturer. CAUTION Do not disassemble the recoil starter. There is a possibility of personal injury with recoil spring. WARNING Improper maintenance could result in serious engine damage or in serious personal injury. Transport and storage ○ Carry the machine by hand with the engine stopped and the muffl er away from your body. ○ Allow the engine to cool, empty the fuel tank and carburetor, and secure the machine before storing or transporting. ○ Store machine out of the reach of children. ○ Clean and maintain the machine carefully and store it in a dry place. ○ Make sure stop switch is off when transporting or storing. ○ Do not store the cut-off wheels in a wet or frost condition. Pay special attention about the abrasive wheel. There is a risk of bursting to using the abrasive wheel wetted. If situations occur which are not covered in this manual, take care and use common sense. Contact Tanaka dealer if you need assistance. 0000BookTCM75EAP.indb90000BookTCM75EAP.indb9 2017/12/1510:43:392017/12/1510:43:39English

Stopping (Fig. 28) Decrease engine speed, and push stop switch (21) to stop position. WARNING Do not put the machine where there are fl ammable materials such as dried grass, since the muffl er is still hot after the engine has stopped. Basic cutting techniques

1. Adjust the wheel guard to shield you from fl ying debris.

2. Cut a straight shallow line (31) to the range to be cut.

3. Cut straight along the line to the required depth.

WARNING ○ Do not overreach or cut above shoulder height.

Operator and bystanders must not stand in the line of rotation of the cut-off wheel. Doing so may result in serious injury or death should the wheel burst.

Never apply lateral pressure (side force) to the cut-off wheel during cutting. Doing so will damage the cut-off wheel.

Do not cut in a curved line. NOTE ○ When cutting, move the machine back and forward along the line in order to be not overheat the cut-off wheel. If you cut the same position in long time, the cut-off wheel may get hot and be weakened. ○ Always cut at full speed at all times with pressing lightly. This is the way to get best effi cient for cutting. ○ Do not cut a deep groove at one time. To make deep groove, cut several times a shallow groove. MAINTENANCE Carburetor adjustment In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is adjusted. A further adjustment may be required, according to climate and altitude. The carburetor has one adjustment possibility: T = Idle speed adjustment screw. Idle speed adjustment (T) (Fig. 30) Check that the pre-fi lter and paper fi lter are clean. When the idle speed is correct, the cutting attachment will not rotate. If adjustment is required, close (clockwise) the T-screw, with the engine running, until the cutting attachment starts to rotate. Open (counter-clockwise) the screw until the cutting attachment stops. You have reached the correct idle speed when the engine runs smoothly in all positions well below the rpm when the cutting attachment starts to rotate. If the cutting attachment still rotates after idle speed adjustment, contact Tanaka dealer. WARNING When the engine is idling, the cutting attachment must not rotate under any circumstances. NOTE ○ Please use combi box spanner for adjusting the T-screw. ○ Do not touch the High speed adjustment (H) and the Low speed adjustment (L) screws on the carburetor. Those are only for Tanaka dealer. If you rotate them, it will cause a serious damage to the machine. Air fi lter (Fig. 31) If the engine power seems to have decreased, it is likely because the air fi lter needs to be cleaned.

1. Before cleaning the air fi lter, pull the choke lever (22) to

prevent dust from entering into the engine.

2. Open cleaner box (B) (32) by loosening cleaner knob

(33) to expose the pre-fi lter (sponge form) (34) inside the cleaner box (B) (32).

3. Clean the pre-fi lter by tapping or blowing it gently. If the

pre-fi lter is still dirty, rinse it in warm soap suds. If the inside of cleaner box (B) (32) that is closed off by the pre-fi lter is dirty with dust, clean the paper-fi lter (35) in the following manner.

4. In order to take out of paper-fi lter (35) and nylon-fi lter

(36), open the cleaner box (A) (37) by loosening the M5 set bolt (38).

5. Clean the nylon-fi lter by tapping or blowing it gently. If

the nylon-fi lter is still dirty, rinse it in warm soap suds.

6. Clean the paper-fi lter by tapping. If you use compressed

air to blow out the dust, apply the air gently from inside.

7. Reassemble the parts to their original positions by

following the aforementioned steps in reverse. NOTE ○ When you remove paper-fi lter and nylon-fi lter, please take care so that dust does not get inside the engine. ○ After rinsing in warm soap suds. Check to make sure that the fi lter is dry before reassembly. An air fi lter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged fi lter must always be replaced. Spark plug (Fig. 31, 32, 33)

1. Remove cleaner box (B) (32) and cleaner box (A) (37).

2. Remove the spark plug by turning it counterclockwise

with the combi box spanner. (Fig. 32)
