Mounting of cutterblade with the hex wrench still in place
–Mount the cutter blade onto the shaft so that the guide of the receiver washer
(4)fits in the arbor hole in the cutter blade. Install the clamp washer (3), cup
(2), and secure the cutter blade with the nut (1). [Tightening torque: 13 - 23 N-m]
NOTE: Always wear gloves when handling the cutter blade.
NOTE: The cutter blade-fastening nut (with spring washer) is a consumable part. If there appears any wear or deformation on the spring washer, replace the nut.
Mounting of nylon cutting head
–The clamp washer (3), cup (2), and nut (1) are not necessary for mounting the nylon cutting head. The nylon cutting head should go on top of the receiver washer (4).
–Insert the hex wrench through the hole in the gear case and rotate the receiver washer (4) until it is locked with the hex wrench.
–Then screw the nylon cutting head onto the shaft by turning it counterclockwise.
–Remove the hex wrench.
–Make sure that the blade is the left way up.

BEFORE START OF OPERATION
Inspection and refill of engine oil
–Perform the following procedure, with the engine cooled down.
–Set the engine level, remove oil cap (Fig. 1), and check to see whether or not there is oil in the range between the upper limit and lower limit marks of the oil pipe (Fig. 2).
–Top up with oil to upper limit mark if oil is insufficient (oil level is close to lower limit mark) (Fig. 3).
–The area surrounding the external marks is transparent, so the amount of oil inside can be checked without having to remove the oil cap.
However, if oil pipe becomes extremely dirty, visibility may be lost, and oil level will have to be checked against stepped section on inside of oil pipe.
–For reference, the oil refill time is about 10h (10 times or 10 tanks of oil refill).
If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P 20)
Recommended oil: SAE 10W-30 oil of API Classification, Class SF or higher (4-stroke engine for automobile)
Oil volume: Approx. 0.08L
Note: If the engine is not kept upright, oil may go into around the engine, and may be refilled excessively.
If the oil is filled above the limit, the oil may be contaminated or may catch fire with white smoke.
Point 1 in Replacement of oil: “Oil gauge”
–Remove dust or dirt near the oil refill port, and detach the oil gauge.
–Keep the detached oil gauge free of sand or dust. Otherwise, any sand or dust adhering to the oil gauge may cause irregular oil circulation or wear on the engine parts, which will result in troubles.

Oil
The area between the external upper and lower limits is transparent, so oil level can be checked externally against these marks.
(1) Keep the engine level, and detach the oil cap.
(2)Fill with oil to upper limit mark. (see Fig. 3)
Use oil bottle when filling.
(3)Securely tighten the oil cap. Insufficient tightening may cause oil leakage.

Note
●Do not replace oil with the engine in a tilted position.
●Filling with oil while engine is tilted leads to overfilling which causes oil contamination and/or white smoke.
Point 2 in Replacement of oil: “If oil spills out”
–If oil spills out between the fuel tank and engine main unit, the oil is sucked into through the cooling air intake port, which will contaminate the engine. Be sure to wipe out spilt oil before start of operation.
REFUELING
Handling of fuel
It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refueling must be performed in a sufficiently ventilated room or in the open air. Never inhale fuel vapor, and keep fuel away from you. If you touch fuel repeatedly or for a long time, the skin becomes dry, which may cause skin disease or allergy. If fuel enters into the eye, clean the eye with fresh water. If your eye remains still irritated, consult your doctor.
Storage period of fuel
Fuel should be used up within a period of 4 weeks, even if it is kept in a special container in a well-ventilated shade. If a special container is not used or if the container is not covered, fuel may deteriorate in one day.
STORAGE OF MACHINE AND REFILL TANK
–Keep the machine and tank at a cool place free from direct sunshine.
–Never keep the fuel in the cabin or trunk.
Fuel
The engine is a four-stroke engine. Be sure to use an automobile gasoline (regular gasoline or premium gasoline).
Points for fuel
–Never use a gasoline mixture which contains engine oil. Otherwise, it will cause excessive carbon accumulation or mechanical troubles.
–Use of deteriorated oil will cause irregular startup.
Refueling
WARNING: INFLAMMABLES STRICTLY PROHIBITED
Gasoline used: Automobile gasoline (unleaded gasoline)
–Loosen the tank cap a little so that there will be no difference in atmospheric pressure.
–Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that the refuel port will be oriented upward. (Never refill fuel full to the oil refill port.)
–Wipe well the periphery of the tank cap to prevent foreign matter from entering into the fuel tank.
–After refueling, securely tighten the tank cap.
●If there is any flaw or damage on the tank cap, replace it.
●The tank cap is consumable, and therefore should be renewed every two to three years.
