Assembly

Please follow the steps in figures 2-5:

1. Mount lower handlebar with 4 bolts on the console. After that mount the upper handlebar. The spacers are needed to be on the inside. As shown on Fig. 2A
2. Attach the clutch handles on the handlebar, as shown on Fig. 2B. Cable which comes out from right side of chassis, should be attached to right side of handlebar. Equivalent for left side.
3. Mount the wheels with the bolts shown on Fig. 3A. The spacers need to be between the wheel and the bolt.
4. Fit the protection guard on the machines as shown on Fig. 4.
5. Mount trimmer line. Follow the procedure step 1-2-3 as shown on Fig. 5.
6. Mount the throttle lever on the handle, as per Fig. 6.

The trimmer line must have a length of max 52 cm and must always be attached in sets. There must be attached trimmer lines on both sides of the trimmer head.
Mounting the start cord in holder: Fig. 7A

1. Pull gently the starter cord from the engine.
2. Attach the starter grip on the rack of handlebar.

Fill the motor with engine oil to the correct level. See changing the oil section for more details.
Clothing

When using the machine, wear close-fitting work clothes, hard-wearing work gloves, ear defenders and non-slip boots with steel toecaps.
Safety zone

While the machine is being operated and the motor is running, do not leave the operation zone marked with arrows on Fig. 9. If it is necessary to leave the operation zone, for example to attach an accessory, first stop the engine.

Starting and stopping the engine

Always check the oil level prior to use!
On engines with a dipstick, the oil level must always be between the min. and max. On engines without dipstick the oil must be visible to the edge on filler hole, when the engine is in a horizontal position. Always use SAE-30 oil. Use only unleaded 95 octane petrol. Never over-fill the gas tank.
Start

1. Set the throttle lever to the max position.
2. Pull the start cord to start the engine. See Fig. 7A. Always feed the start cord back into the engine by hand.
3. Activate the trimmer activation handle. Fig. 8A.
4. Activate the self-propelled handle. Fig. 8B.

Stop

1. Release both clutch handles.
2. Set the throttle lever to the stop position.

Vibrations may travel up into the handle during use. We therefore recommend taking a break, every 2 hours.

Operating the machine

Remove all foreign objects from the work area before using the machine. Stones, glass, branches and similar items may damage the machine. Also check the bolts are tightened. Start the motor as per the instructions above. Stand clear of the machine’s moving parts. Never attempt to move the machine in any way other than intended for normal use while the motor is running.
KEEP A SAFETY DISTANCE OF 15 METERS.
The machine can work in almost any kind of vegetation. The trimmer head turns clockwise which means that the machine throws the grass out on the right side. The machine has a low center of mass and large wheels. This makes it suitable for working on slopes with a gradient of up to 15%. Warning: Avoid driving on slopes steeper than 15%, as the engine in such case will lack lubrication which can result in a damaged engine. The machine workload should match the trimmer capacity. This is ensured by always keeping the same steady RPM on the trimmer head. Avoid downspin in RPM. A downspin in the RPM on trimmer head can be a sign on overload.
Adjustment of the cutting height

Follow the adjustment procedure as shown in Fig. 10 It is possible to adjust the cutting height on the trimmer head in several positions between 45-120 mm. To adjust the trimmer height, you have to loosen the two 4 mm allen screws. Then you can adjust the trimmer head up and down. Tighten both screws again once the required cutting height is chosen.

Cleaning

The machine should be cleaned after use. Use a garden hose to wash off soil and dirt. Remove the trimmer head from the trimmer axel to remove wedged grass etc. from the rotor shaft. The chassis number should only be cleaned with a damp cloth to avoid unnecessary wear. Avoid using a high-pressure washer during cleaning.
Changing the oil

The oil should initially be changed after the first 5 hours of use, and thereafter once per year. Use an oil extractor kit.

1. Suck the oil up through the oil filler hole using the syringe. Use the hose to reach the sump.
2. Transfer the used oil to the container.
3. Fill the engine with new SAE-30 oil.
4. Check the oil level using the dipstick.

Remember to dispose of used oil in a safe way. Oil and oil extractor kit are not included

Storage

• If the machine is likely to be stored unused for prolonged periods, follow the instructions below. This will ensure longer machine lifetime.
• Use a garden hose to wash off soil, grass and dirt. Remove any grass, etc. from the shaft. The chassis number should only be cleaned with a damp cloth to avoid unnecessary wear. Avoid using a high-pressure washer during cleaning.
• Wipe the machine with a damp cloth so that all surfaces are clean. Wipe the surfaces down with an oily cloth to prevent rust.
• Always store the machine in a dry, clean location.
• Empty or run the machine until dry of petrol.
