(4) Pull recoil starter briskly, taking care to keep the handle in your grasp and not allowing it to snap back. (Fig. 18)
natural_image
Line drawing of a hand operating a mechanical device with a black arrow pointing to the handle (no text or symbols present)Fig. 18
(5) When you hear the engine want to start, return choke lever to RUN position (open) (B). (Fig. 17)
(6) Pull recoil starter briskly again. (Fig. 18)
NOTE
If engine does not start, repeat procedures from 2 to 5.
(7) Then allow the engine about 2–3 minutes to warm up before subjecting it to any load.
(8) Check that the cutting attachment does not rotate when the engine is idling.
- Starting the warm engine
Use only 1, 6 and 8 of the starting procedure for a cold engine.
If the engine does not start, use the same starting procedure as for a cold engine.
Cutting
WARNING
● Always use the harness (if so equipped) and wear the proper attire and protective equipment when operating the unit. (Fig. 19)
- Keep others including children, animals, bystanders and helpers outside the 15 m hazard zone. Stop the engine immediately if you are approached. (Fig. 20)
- When grass or vines wrap around attachment, stop engine and attachment and remove them. Continuing operation with grass or vines wrapped around the attachment may result in damages such as early abrasion of the clutch.
Fig. 19 Fig. 20
NOTE
Use in accordance with local laws and regulations.
Using a semi-auto cutting head
○ Set the engine at high speed when using this attachment.
○ Cut grass from left to right. The cut grass will be discharged away from the body, minimizing transfer to your clothes. (Fig. 21)
○ Cut grass from right to left as the cutting attachment of the curved drive shaft tube model rotates clockwise.
With nylon cord, use about 3/4" (2 cm) of the end of the cord to cut grass. Using the full length of the cord will reduce rotation speed and make cutting difficult.
Fig. 21
NOTE
Automatically feeds more nylon cutting line when it is tapped at low rpm (not greater than 4,500 min-1).
WARNING
● This product is equipped with a line limiter that will automatically cut any excess cord. When operating the unit, do not remove the guard or line limiter.
As the resistance is greater for nylon cords as opposed to blades, mishandling could increase engine load and result in damage.
- Do not use with the engine set at low speeds. If the engine speed is low, grass may wrap around the attachment, causing the clutch to slip which could result in clutch abrasion.
- With nylon cord cutters, always use over 5-7/8" (15 cm) of cord. If the length of the cord is too short, rotation speed will increase and may cause damage to the nylon cord cutter. As the curved drive shaft tube model in particular is not equipped with a deceleration mechanism, the possibility of increased rotation speed for the cutting attachment is high.
Stopping (Fig. 22)
Decrease engine speed and run at an idle for a few minutes, then turn off ignition switch (25).
Fig. 22
WARNING
A cutting attachment can injure while it continues to spin after the engine is stopped or power control is released. When the unit is turned off, make sure the cutting attachment has stopped before the unit is set down.
MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY NON-ROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.
Carburetor adjustment (Fig. 23)
natural_image
Line drawing of a mechanical device with hands operating it (no text or symbols)Fig. 23
WARNING
● The cutting attachment may be spinning during carburetor adjustments.
● Never start the engine without the complete clutch cover and tube assembled! Otherwise the clutch can come loose and cause personal injuries.
In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is basically 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)
Check that the air fi Iter is clean. Be sure the cutting attachment stop turning when the engine idle. 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.
NOTE
Standard Idle rpm is 2,800 - 3,200 min -1.
WARNING
When the engine is idling the cutting attachment must under no circumstances rotate.
Air fi Iter (Fig. 24)
The air filter (29) must be cleaned from dust and dirt in order to avoid:
○ Carburetor malfunctions
○ Starting problems
○ Engine power reduction
○ Unnecessary wear on the engine parts
○ Abnormal fuel consumption
Clean the air fi lter daily or more often if working in exceptionally dusty areas.
natural_image
Technical line drawing of a mechanical component with internal parts and part number 29 (no text or symbols present)Fig. 24
Cleaning the air fi Iter
Open the air filter cover and remove the air filter (29). Rinse it in warm soap suds. Check 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.
Fuel fi Iter (Fig. 25)
Check the fuel fi iter occasionally for clogging as insufficient fuel flow could affect engine speed. Drain all fuel from fuel tank and pull fuel fi iter (30) from tank. Rinse it in warm water with detergent. Rinse thoroughly until all traces of detergent are eliminated. Squeeze, away excess water and allow element to air dry.
NOTE
If the fuel fi lter (30) is hard due to excessive dirt buildup, replace it.
natural_image
Line drawing of a mechanical device with labeled component '30' (no text or symbols on the device itself)Fig. 25
Spark plug (Fig. 26)
The spark plug condition is influenced by:
○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi Iter
○ Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting difficulties. If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Re-adjust if necessary. The correct gap is 0.024" (0.6 mm). The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.
Fig. 26
NOTE
In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped with resistor spark plug, use same type of spark plug for replacement.
Flexible drive shaft (Fig. 27)
(curved drive shaft tube model)
Flexible drive shaft should be removed and lubricated with good quality lithium grease every 20 hours. To remove the flexible shaft, first remove screw (31), loosen bolt (32) and remove the cutter case then pull the shaft out of the drive shaft tube. Clean the shaft off and apply a generous coat of lithium grease to it and insert if back into the drive shaft tube, turn it unit it drops into place then install the cutter case, install & tighten screw (31) and bolt (32).
Fig. 27
Gear case (Fig. 28)
Check gear case or angle gear for grease level about every 50 hours of operation by removing the grease fi ller plug on the side of gear case. If no grease can be seen on the fl anks of the gears, fi ll the gear case with quality lithium based multipurpose grease up to 3/4. Do not completely fi ll the gear case.

● Before attempting inspection or maintenance of the gear case, make sure the case has cooled.
Semi-auto cutting head
Nylon line replacement
(1) Remove the case (33) by firmly pushing inward the locking tabs with your thumbs as shown in Fig. 29.
Fig. 29
(2) After removing the case, take out the reel and discard the remaining line.
(3) Fold the new nylon line unevenly in half as shown in picture.
Hook the U-shaped end of the nylon line into the groove (34) on the center partition of the reel. Wind both halves of the line on the reel in the same direction, keeping each half of the line on its own side of the partition. (Fig. 30)
Fig. 30
(4) Push each line into the stopper holes (35), leaving the loose ends approx. 4" (10 cm) in length. (Fig. 31)
Fig. 31
(5) Insert both loose ends of the line through the cord guide (36) when placing the reel in the case. (Fig. 32)
Fig. 32
NOTE
When placing a reel in the case, try to line up the stopper holes (35) with the cord guide (36) for easier line release later.
(6) Place the cover over the case so that the cap locking tabs (37) on the case meet the long holes (38) on the cover. Then push the case securely until it clicks into place. (Fig. 33)
Fig. 33
(7) The initial cutting line length should be approx. 4-11/32"-5-1/2" (11-14 cm) and should be equal on both sides. (Fig. 34)
