Handling fuels / Refuelling

- Stop the engine before refuelling.

- Keep away from open flame or sparks and do not smoke while refuelling or mixing fuel.

- Let the engine cool down before refuelling.

- Fuel may contain substances similar to solvents. Eyes and skin

should not come in contact with mineral oil products. Always wear protective gloves when refuelling. Frequently clean and change protective clothes. Do not breathe in fuel vapors. Inhalation of fuel vapours can be hazardous to your health.

-Before refuelling the brushcutter make sure it is on its side in a stabile position.

-Do not spill fuel or oil. When you have spilt fuel or oil immediately clean the brushcutter. Fuel should not come in contact with clothes. If your clothes come in contact with fuel, change them at once.

-Ensure that no fuel or chain oil oozes into the soil (environmental protection). Use an appropriate base.

-Refuelling is not allowed in closed rooms. Fuel vapors will accumulate near the floor (explosion hazard).

-Carefully tighten the locking screw of the fuel tank and inspect the fuel cap at regular intervals.

-Change the place before starting the engine (at least 3 meters from the place of refuelling) (6).

-Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in the near future.

-Use only approved and marked containers for the transport and storage of fuel. Ensure children have no access to fuel.

Putting into operation

Do not work alone. Another person must be nearby in case of emergencies (within shouting distance).

Children and other persons must remain more than 15 meters (50 feet) from the working area. Keep an eye out for animals as well (7).

- Before use always check that the brushcutter is safe for operation:

Make sure the cutting tool is securely installed. The throttle must automatically return to the off position when released, and the throttle lever lock must work properly. The cutting tool must not turn during idling. The handles should be clean and dry. The on/off switch must function properly. The guard must be undamaged and securely installed in the correct position.

Otherwise you are in danger of injury!

- Start the brushcutter only in accordance with the instructions. Do not use any other methods for starting the engine (8)!

- Use this brushcutter and its cutting tools only for the uses they are intended for as specified in the documentation.

- Start the brushcutter only after complete assembly and inspection. Operation of the device is only permitted after all the appropriate accessories are attached!

- The cutting tool must be equipped with its appropriate guard. Never run the cutter without this guard!

- The cutting tool must not turn during idling. If necessary adjust the idling speed.

- Before starting, make sure that the cutting tool has no contact with hard objects such as branches, stones etc.

- The engine must be switched off immediately if there are any noticeable changes in the behavior of the equipment.

- Should the cutting tool hit stones or other hard objects, immediately switch off the engine and inspect the cutting tool.

- Inspect the cutting tool at frequent intervals for damage (detect hairline cracks by means of tapping - noise test). Hairline cracks can occur in the region of the base of the

teeth after long use. Damaged cutting tools and cutting tools with hairline cracks must not be used any longer under any circumstances.

-Operate the brushcutter only with the shoulder strap

attached, which is to be suitably adjusted before putting the brushcutter into operation. It is essential to adjust the shoulder strap according to the user’s size to prevent fatigue during use. Never hold the cutter with one hand during use.

-When working with the brushcutter always hold it with both hands (9). Keep proper footing and balance at all times.

-Operate the brushcutter in such a manner as to avoid inhalation of the exhaust gases. Do not start or operate the brushcutter in closed rooms (risk of gas poisoning). Carbon monoxide is an odorless gas. Work only in well-ventilated places.

-When taking a break or leaving the brushcutter unattended, turn off the engine (10) and set the brushcutter down in such a way that there is no risk of injury to yourself or others.

-Never put the hot brushcutter onto dry grass or onto any combustible materials.

-Shut off the engine during transport or when moving on to a new location (10).

-Never operate the engine with a faulty exhaust muffler.

Kickback

During operation the brushcutter can kickback in an uncontrolled manner. This can happen when the cutting blade (4- tooth star blade) comes into contact with hard objects such as stumps, fenceposts, tree trunks, woody brush or large rocks.

Thiscanflingthebrushcuttertoonesidewithgreatforceand speed (injury hazard).

To avoid kickback, observe the following:

-Remove foreign objects from the cutting area and be aware of plants and objects in the area.

-The cutting tool must be turning at full speed before starting cuts.

-The danger of kickback is heightened in the darkened area (illustration), especially if using a metal cutting tool!

Working behavior / Method of working

-Use the brushcutter only in good light and visibility. During the winter season beware of slippery or wet areas, ice and snow (risk of slipping). Always ensure a safe footing.

-Never cut above your shoulder height.

-Never stand on a ladder and run the brushcutter.

-Never climb up into trees to perform cutting operations with the brushcutter.

-Never work on unstable surfaces.

-Make sure the cutting area is free of foreign objects such as stones and metal items. Foreign particles can rebound (danger of injury, 12), damage the cutting tool and cause dangerous kickbacks.

-Before commencing cutting, the cutting tool must have reached full working speed.

Applications for cutting tools

Employ only the correct cutting tool for the job in hand! Do not use tools for jobs they are not designed for.

2-line trimmer head (13)

Only for cutting up against walls, fences, trees, posts etc. and at lawn edges (as an adjunct to a lawnmower).

4-tooth star blade (14)

For cutting grass or heavy weeds. Perform this cutting work by swinging the brush cutter evenly in half-circles from left to right (15, similar to a scythe).

Transport

-When transporting the equipment or moving to another working location, the brushcutter must be switched off in order to avoid unintentionally starting the cutting tool.

-Never transport the brushcutter when the cutting tool is in operation!

-The tool protection included with the equipment must always be used if the brushcutter is transported over longer distances.

-Ensure that the brushcutter is safely secured so that no fuel can run out before transporting it in a vehicle. Empty the fuel tank before transporting the brushcutter.

-Before shipping the brushcutter, completely empty the fuel tank.

11 Caution: Kickback!

Storage

-The brushcutter must be safely stored in a dry room. Use the tool protection for metal cutting tools. Keep the brushcutter out of reach of children.

-If the brushcutter is stored for a long period of time, it should be given a thorough maintenance check and a complete inspection at an authorized DOLMAR service centre.

-If the brushcutter is stored for a long period of time, the fuel tank should be completely emptied and the carburetor run dry. Fuels may only be stored for a limited period of time and could cause deposits to form in the tank or in the carburetor.

-Fuel remains in reserve canisters should be used for other engines or disposed of.

Maintenance

-Always make sure the brushcutter is in good working order before using it. This includes in particular the cutting tool, guard, harness and fuel system (check for leaks). Particular attention must be paid to the cutting blades, which must be correctly sharpened.

CAUTION: Metal cutting tools must be sharpened only at an authorized service centre!

A tool which has been improperly sharpened can cause unbalance and thus considerable danger of injury. Apart from this, the equipment may be damaged due to vibrations.

-When changing the cutting tool, cleaning the brushcutter and the cutting tool etc., it is essential to switch off the engine and pull the spark plug cap.

-Replace cracked, bent, warped, damaged or dull cutting tools immediately. Never straighten or weld damaged cutting tools.

-Operate the brushcutter with as little noise and pollution as possible. In particular check the correct setting of the carburetor.

-Clean the brushcutter at regular intervals and check that all screws and nuts are well tightened.

-Never service or store the brushcutter near open flames (16)!

-Always store the brushcutter in a locked storage area, with the fuel tank completely empty and the carburetor run dry.

Observe the accident prevention instructions issued by the relevant trade associations and insurance companies. Do not make any modifications to the brushcutter you will only be putting your own safety at risk!

The performance of maintenance or repair work by the user is limited to those activities described in this instruction manual. All other work must be done by the DOLMAR customer service (17).

Use only original DOLMAR spares and accessories.

The use of non DOLMAR spares, accessories, or cutting tools increases the risk of accident. DOLMAR will not accept any liability for accidents or damage caused by the use of non-approved cutting tools and fixing devices of cutting tools, or accessories.

First Aid

A first aid kit should always be nearby as a precaution in the event of an accident.

Immediately replace any items taken from the first aid kit.

When calling for help, give the following information:

Place of accident, what happened, number of persons injured, nature of injuries, your name.
