FUEL/REFUELLING
BEFORE START OF OPERATION
Inspection and reill 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 insuficient (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 reill time is about 10 h (every 10 refuelling).
If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P20)
Recommended oil: SAE 10W-30 oil of API Classiication, Class SF or higher (4-stroke engine for automobile)
Oil volume: |
Approx. 0.08 L |
NOTE: If the engine is not kept upright, oil may go into around the engine, and may be reilled excessively.
If the oil is illed above the limit, the oil may be contaminated or may catch ire with white smoke.
Point 1 in Replacement of oil: “Oil cap”
-Remove dust or dirt near the oil reill port, and detach the oil cap.
-Keep the detached oil cap free of sand or dust. Otherwise, any sand or dust adhering to the oil cap may cause irregular oil circulation or wear on the engine parts, which will result in troubles.

(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 illing.
(3) Securely tighten the oil cap. Insuficient 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 overilling 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 spilled oil before start of operation.
REFUELLING
Handling of fuel
It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refuelling must be performed in a suficiently ventilated room or in the open air. Never inhale fuel vapors, 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 comes 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 within a period of 4 weeks, even if it is kept in a special container in a well-ventilated and shaded area.
Otherwise, 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 a car.
Fuel
The engine is a four-stroke engine. Be sure to use an unleaded automobile gasoline 87 or higher octane ((R+M)/2). It may contain no more than 10% alcohol (E-10).
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 start-up.
Refuelling
WARNING: INFLAMMABLES STRICTLY PROHIBITED
-Loosen the tank cap a little to release the tank pressure.
-Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that the refuel port will be oriented upward. (DO NOT ill fuel up to the top of the tank.)
-Wipe well the periphery of the tank cap to prevent foreign matter from entering the fuel tank.
-After refuelling, securely tighten the tank cap.
•If there is any law or damage on the tank cap, replace it.
•The tank cap wears out in course of time. Replace it every two to three years.

PRECAUTIONS BEFORE STARTING THE ENGINE
-At all times allow a 15-meter diameter safety zone around the working area. Make sure that all persons (in particular children) and/or animals remain outside this zone.
-Before using the pole hedge trimmer, make sure that the machine is in safe operational condition. Make sure that the cutting blades are not damaged, and check the throttle lever for easy action. Make sure that the cutting blades are not in motion when the engine is idling. If the machine is not operating normally, contact your dealer to have the machine adjusted. Make sure that the handles are clean and dry, and test whether the I-O switch is functioning properly. Start the engine only in accordance with the instructions given in this manual. Do not use any other methods to start the pole hedge trimmer.
-Start the engine of the pole hedge trimmer only after having read and fully understood the instructions. Never attempt to start a pole hedge trimmer that has not been fully assembled. Serious injury may result otherwise.
-Before starting the engine, always make sure that the cutting blades are not obstructed by stones, branches or any other solid objects.
-Check the working area for wires, cord, glass or other foreign objects that could get caught in the cutting blades.
-Electrical shock: Be aware of all electrical lines in the vicinity. Check the entire work area for the presence of power lines and electrical fences before starting to work.
POINTS IN OPERATION AND HOW TO STOP
Observe the applicable accident prevention regulations!
STARTING
Move at least 3 m away from the place of refuelling. Put the pole hedge trimmer on a clean piece of ground taking care that the cutting blades do not come into contact with the ground or any other objects.
A: Cold start
1)Set this machine on a lat space.
2)Set the I-O switch (1) to OPERATION.
3)Primer pump
Continue to push the primer pump (2) until the fuel comes into the primer pump. (In general, fuel comes into the primer pump by 7 to 10 pushes.) If the primer pump is pushed excessively, an excess of gasoline returns to the fuel tank.

4)Recoil starter
Pull the start knob gently until it is hard to pull (compression point). Then, return the start knob, and pull it strongly. Never pull the rope to the full extension. Once the start knob is pulled, never release your hand immediately. Hold the start knob until it returns to its original point.
5)Warm-up operation
Continue warm-up operation for 2 to 3 minutes.
NOTE: In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry the electrode section of the spark plug.
B: Startup after warm-up operation
1)Repeat pushing the primer pump gently.
2)Keep the throttle lever at the idling position.
3)Pull the recoil starter strongly.
4)If it is dificult to start the engine, open the throttle by about 1/3.
Pay attention to the cutting blades which may move.
At times, such as winter, when starting the engine is dificult, operate choke lever with the following procedure when starting engine.
•After implementing startup steps 1) to 3), set choke lever to the CLOSE position.
•Implement startup step 4) and start engine.
•Once engine starts, set choke lever to the OPEN position.
•Implement startup step 5) and complete warm up.
CAUTION: If a bang (explosive sound) is heard and the engine stops, or the just-started engine stalls before the choke lever is operated, return the choke lever to the OPEN position, and pull the starter knob a few times again to start the engine.
CAUTION: If the choke lever is left in the CLOSE position, and the starter knob
merely pulled repeatedly, to much fuel will be sucked in, and the engine will become dificult to start.
