FUEL AND REFUELING
HANDLING THE FUEL SAFELY

• Always handle fuel with care, it is highly flammable.
• Always refuel outdoors where there are no sparks and flames. Do not inhale fuel vapors.
• Do not let petrol or oil come in contact with your skin.
• Keep petrol and oil away from the eyes. If petrol or oil comes in contact with the eyes, wash them immediately with clean water. If irritation is still present, see a doctor immediately.
• Clean up spilled petrol immediately.

MIXING THE FUEL (Fig. 3)

• This product is powered by a 2-stroke engine and requires pre-mixing petrol and 2-stroke oil. Pre-mix unleaded petrol and 2-stroke engine oil in a clean container approved for petrol.
• This engine is certified to operate on unleaded petrol intended for automotive use with an octane rating of 91 ([R + M] / 2) or higher.
• Do not use any type of pre-mixed petrol/oil from fuel service stations, this includes the pre-mixed petrol/oil intended for use in mopeds, motorcycles, etc.
• Use synthetic 2-stroke oil only. Do not use automotive oil or 2-stroke outboard oil.
• Mix 2% synthetic 2-stroke oil into the petrol. This is a 50:1 ratio.
• Mix the fuel thoroughly and also each time before fueling.
• Mix in small quantities. Do not mix quantities larger than usable in a 30 day period. Synthetic 2-stroke oil containing a fuel stabilizer is recommended.

FILLING THE TANK

• The clean surface around the fuel cap prevents contamination.
• Loosen the fuel cap slowly to release pressure and to keep fuel from escaping around the cap.
• Carefully pour the fuel mixture into the tank. Avoid spillage.
• Prior to replacing the fuel cap, clean and inspect the gasket.
• Immediately replace the fuel cap and hand tightens.
  Wipe up any fuel spillage. Move 9 m away from the refueling site before starting the engine.

Note: It is normal for smoke to be emitted from a new engine during and after first use.
WARNING
Always shut off the engine before fueling. Never add fuel to a machine with a running or hot engine.
Move at least 9 m from the refueling site before starting the engine. Do not smoke!

STARTING AND STOPPING (Fig. 4)
WARNING
Never start or run the engine inside a closed or poorly ventilated area; breathing exhaust fumes can kill.
NOTE: Be sure to return the stop switch to the “I” (RUN) position before trying to start the unit.
To start a cold engine:
DO NOT squeeze the throttle trigger until the engine starts and runs.

• Lay the trimmer on a flat, bare surface.
• PRIME – Press the primer bulb 10 times.
• SET the start lever to the START position.
• PULL the rope quickly and sharply straight up until the engine starts.
• Then squeeze the trigger to run.

NOTE: Squeezing and releasing the throttle trigger releases the start lever to the RUN position.
If the engine stalls, set the start lever to the RUN position ” “. Then pull the starter rope until the unit starts.
To start a warm engine:
Make sure the carburetor is set to RUN position.
PULL the rope quickly and sharply straight up until the engine starts.
To stop the engine:
Press and hold the switch in the stop “ O ” position until the engine stops.
OPERATING THE TRIMMER (Fig. 5)
Hold the trimmer with the right hand on the rear handle and the left hand on the front handle. Keep a firm grip with both hands while in operation. Trimmer should be held at a comfortable position with the rear handle about hip height.
Always operate trimmer at full throttle. Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and bump head which may cause damage from overheating. If the grass becomes wrapped around the bump head, stop the engine, disconnect the spark plug wire, and remove the grass. Prolonged cutting at partial throttle will result in oil dripping from the silencer.
CUTTING TIPS (Fig. 6)
When cutting makes sure the cutter head is at a slight angle as shown while still approximately parallel to the ground surface. In tall grass cut from the top down to ensure the moving parts do not get tangled with the long grass. Move the head in steady strokes from right to left as you work through the grass.
ADVANCING THE LINE (Fig. 7)
If the line becomes short, tap the head on the ground as shown to extend more line. Take care not to ‘crash’ it against a hard surface.

MAINTENANCE

WARNING
Use only the original manufacturer’s replacement parts, accessories, and attachments. Failure to do so can cause possible injury, poor performance and may void your warranty.

• You may make adjustments and repairs described here. For other repairs, have the trimmer serviced by an authorized service agent?
• Consequences of improper maintenance may include excess carbon deposits resulting in loss of performance and discharge of black oily residue dripping from the silencer.
• Make sure all guards, straps, deflectors, and handles are properly and securely attached to avoid the risk of personal injury.
• the cutting attachment must not rotate in idle mode. If this requirement is not satisfied, the idle speed needs adjustment (Fig.10) or the machine needs urgent maintenance by a qualified technician.

SPOOL REPLACEMENT (Fig. 11)
LINE REPLACEMENT (Fig. 11)

• Ensure the unit is in the off position
• Remove the spark plug lead, to prevent accidental starting.
• Use 2.4mm diameter monofilament string.
• Cut one piece of string approximately 6.0m in length
• Rotate the knob on the string head until the line on the knob aligns with arrows on top of the string head.
• Insert one end of the string into the eyelet located on the side of the string head and push until string comes out through the eyelet on the other side. Continue to push the string through the string head until the middle section of the string is inside the string head and the string outside the string head is evenly divided on each side.
• Rotate the knob on the string head counterclockwise to wind the string
• Wind the string until approximately 20cm remains protruding from the string head.

CLEANING THE EXHAUST PORT AND SILENCER
Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port, and silencer may become blocked with carbon deposits. If you notice a power loss with your petrol-powered tool, a qualified service technician will need to remove these deposits to restore performance.
SPARK ARRESTOR
The spark arrestor must be cleaned or replaced every 25 hours or yearly to ensure the proper performance of your product. Spark arrestors may be in different locations depending on the model purchased. Please contact your nearest service dealer for the location of the spark arrestor for your model.
CLEARING THE AIR FILTER SCREEN (Fig. 8)
For proper performance and long life, keep the air filter screen clean.

• Remove the air filter cover by pushing down on the latch with your thumb while gently pulling on the cover.
• Brush the air filter screen lightly to clean.
• Replace the air filter cover by inserting the tabs on the bottom of the cover into the slots on the air filter base; push the cover-up until it latches securely in place.

FUEL CAP
WARNING
A leaking fuel cap is a fire hazard and must be replaced immediately.
The fuel cap contains a non-serviceable filter and a check valve. A clogged fuel filter will cause poor engine performance. If performance improves when the fuel cap is loosened, the check valve may be faulty or the filter clogged.
Replace fuel cap if required.
SPARK PLUG REPLACEMENT (Fig. 9)
This engine uses a Champion RCJ-6Y or NGK BPMR7A spark plug with a .05 in. electrode gap. Use an exact replacement and replace it annually.
IDLE SPEED ADJUSTMENT (Fig. 10)
If the cutting attachment turns at idle, the idle speed screw needs adjusting on the engine. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the cutting attachment movement. If the cutting attachment still moves at idle speed, contact a service dealer for adjustment and discontinue use until the repair is made.
STORING THE PRODUCT

• Clean all foreign material from the product. Store idle units indoors in a dry, well-ventilated area that is in-accessible to children. Keep away from corrosive agents such as garden chemicals.
• Abide by all ISO and local regulations for the safe storage and handling of petrol.
