Wheels and flanges with arbor holes that do not match the mounting hardware of the machine will run off - balance, vibrate excessively and may cause loss of control.
☐ It is important to use only cut-off wheels designed for use on hand-held cut-off machines. It is dangerous to use a cut-off wheel that is not intended for a hand-held cut-off machine.
Fuel safety
○ Mix and pour fuel outdoors and where there are no sparks or flames.
○ Use a container approved for fuel.
○ Wipe off all fuel spills and allow any remaining fuel to evaporate before starting engine.
○ Move at least 3 m away from fueling site before starting engine.
○ Stop engine and let it cool for a few minutes before opening fuel tank cap.
○ Store the machine and fuel in area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc.

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 firmly with the right hand on the rear handle and the left hand on the front handle.

○ Sparks generated from cutting operations can cause fires. Always have adequate fire 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 muffler 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.

Basic cutting techniques
-
Adjust the wheel guard to shield you from flying debris.
-
Cut a straight shallow line (31) to the range to be cut. (Fig. 29)
-
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 efficient 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-filter and paper filter 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 Iter (Fig. 31)
If the engine power seems to have decreased, it is likely because the air filter needs to be cleaned.
- Before cleaning the air filter, pull the choke lever (22) to prevent dust from entering into the engine.
-
Open cleaner box (B) (32) by loosening cleaner knob (33) to expose the pre-filter (sponge form) (34) inside the cleaner box (B) (32).
-
Clean the pre-filter by tapping or blowing it gently. If the pre-filter is still dirty, rinse it in warm soap suds.
If the inside of cleaner box (B) (32) that is closed off by the pre-filter is dirty with dust, clean the paper-filter (35) in the following manner. - In order to take out of paper-filter (35) and nylon-filter (36), open the cleaner box (A) (37) by loosening the M5 set bolt (38).
- Clean the nylon-filter by tapping or blowing it gently. If the nylon-fi liter is still dirty, rinse it in warm soap suds.
- Clean the paper-filter by tapping. If you use compressed air to blow out the dust, apply the air gently from inside.
- Reassemble the parts to their original positions by following the aforementioned steps in reverse.
NOTE
When you remove paper-filter and nylon-filter, please take care so that dust does not get inside the engine.
○ After rinsing in warm soap suds. Check to make sure that the filter is dry before reassembly. An air filter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged filter must always be replaced.
Spark plug (Fig. 31, 32, 33)
-
Remove cleaner box (B) (32) and cleaner box (A) (37). (Fig. 31)
-
Remove the spark plug by turning it counterclockwise with the combi box spanner. (Fig. 32)
-
Clean the spark plug if it is dirty. Check the electrode gap. The correct gap is 0.6 mm. (Fig. 33)
NOTE
○ When you remove the spark plug, please take care so that dust does not get inside the engine.
☐ The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.
Fuel fi Iter (Fig. 34)
Remove the fuel filter (39) from the fuel tank and thoroughly wash it in solvent. After that, push the fuel filter into the tank completely.
NOTE
If the fuel filter (39) is hard due to dust and dirt, it must be replaced.
Anti-vibration systems (Fig. 35)
Check the springs (40) for any loosening or damage. If you find any failure in those parts, please contact a Tanaka dealer.
Replacing of belt
- Remove nut (9) using the combi box spanner (6) and loosen the tensioner bolt (11) by rotating it counterclockwise with the hex. wrench (4). Then, remove the arm cover (10). (Fig. 11, 12)
- Loosen the three bolts (41) on the clutch cover (42) and remove clutch cover (42). (Fig. 36)
- Remove the belt (43) and set a new one in the grooves of the pulleys (44)(45) securely. (Fig. 37, 38)
- Before assembling, turn the tensioner bolt (11) and adjust the length protrusion of the tensioner bolt (11) from the arm cover (10) to 0 mm. (Fig. 39)
