Preparations Before you can put the brushcutter into operation, you must assemble and prepare it for regular operation. The brushcutter is not allowed to be started until it has been completely assembled and a functional test has been carried out! Wear protective gloves for all work on the brushcutter! Installing the handle Depending on whether you have decided to purchase the BCX3400 or the BCX3410 brushcutter, your machine will be equipped with a C-handle or with a U-handle.
Installing the line blade and cutter guard On the basis of legal accident prevention regulations, the cutter guard included in the scope of delivery (and no other cutter guard) must be installed! To ensure your personal protection, the brushcutter is not allowed to be put into operation without the cutter guard under no circumstances whatsoever! Caution: The enclosed blade, which is fastened to the cutter guard in order to adjust the lines of the 2-line trimmer head, is sharp! The tools you will require are
4-tooth star blade To install the cutting tool, lay down the brushcutter so that it is resting on its handle in stable position. The tool you will require is the: • Combination wrench plus screwdriver as a handle • e.g. the medium-sized Allen key as an assembly pin 1 Place the mounting disk (1) on the gearbox shaft (2) so that one lateral cut-out (3) lines up with the cut-out (4) in the angular gearbox.
Refueling the brushcutter When refueling the brushcutter, please note the following information at all times! No smoking and no open fires! Do not refuel in closed rooms! Fuel vapors will accumulate on the ground (risk of explosion)! Fuels can contain solvent-like substances. Prevent contact of the eyes and skin with mineral oil products. Wear gloves when refueling. Change and clean your protective clothing more frequently. Do not inhale fuel vapors.
4 Screw the tank cap on tightly again. 5 Clean the tank cap and the surrounding area thoroughly. When laying down the dipstick, make sure that it does not come into contact with dirt under no circumstances whatsoever! Remove dirt immediately whenever necessary! 2 6 Turn the dipstick (2) out of the opening anticlockwise. 7 Upon first-time operation of the brushcutter, use a suitable filling bottle to fill 80 cm3 of engine oil up to the bottom edge of the filling opening (3).
Operation Since you have performed all the preparations, the brushcutter can now be put into operation. The brushcutter is not allowed to be started until it has been completely assembled (see chapter "Preparations") and a functional test has been carried out! Observe the accident prevention regulations! For all work performed with the brushcutter: Wear protective gloves! Wear safety shoes! Wear a helmet as well as face, eye and hearing protection! Never work alone.
Starting Move at least three meters away from the refueling location in order to start the brushcutter! To start the brushcutter, lay it down on a sufficiently clear location so that it is resting on its foot in stable position and the cutting tool does not come into contact with anything else, neither with the ground nor with other objects. 3 meters Cold starting If there are any starting problems, excessively stored fuel could be the reason.
Checking and adjusting the idle speed The carburetor of the brushcutter is equipped with a fixed jet. This means that you will only need to adjust the idle speed, e.g. if your machine is a new machine or the cutting tool is rotating at idle. Make sure that the air filter is always clean! Never run the brushcutter under full load immediately; instead, let the engine warm up for approx. three to five minutes at medium speed. At idle, the cutting tool must no longer rotate.
Maintenance The maintenance work described below must be performed regularly and properly in order to guarantee long service life of your brushcutter and to prevent any form of damage. Warranty claims will only be recognized in that case.
Readjusting the line of the 2-line trimmer head The line length can be adjusted at any time with the best possible results by tapping the line trimmer head on the ground lightly during the mowing operation. The lengthening of the line amounts to approx. 40 mm for each releasing operation. The line blade cuts off projecting ends of the line automatically. Checking/replacing the line of the 2-line trimmer head The new nylon line must be four meters long and have a diameter of Ø 3.
Daily maintenance The following maintenance work must be carried out each time after the brushcutter has been used. Cleaning the air filter If the workplace is very dusty or sandy, the filter must be cleaned at regular intervals, due to the fact that only a clean air filter will guarantee full engine performance.
If you want to check the igniting spark (otherwise continue with step 10): 5 Plug the spark plug connector onto the unscrewed spark plug. 6 Use the combination wrench to make ground contact to the cylinder. 7 Use a pair of insulated pliers to press the spark plug connector with the spark plug lightly against the combination wrench but as far away as possible from the spark plug hole. 8 Push the short-circuit switch (5) to "START". 9 Pull the starter cable forcefully.
The tools you will require are two clean rags and a base surface. Materials: 80 cm3 of SAE 10W‑30 engine oil (classification API SF) 1 Start the engine (see chapter "Putting into operation"). 2 Warm up the engine for 3–5 minutes at medium speed. 3 Lay down the brushcutter on a level surface, so that it is resting on its foot in stable position, and wait three minutes. Then the oil will have accumulated in the crankcase. 2 4 Cover the gasoline tank with a clean rag (1) as shown in the illustration.
Service after 50 tank fill-ups After every 50 tank fill-ups, the brushcutter must be thoroughly serviced and checked in a MAKITA service center. Overview of maintenance and care The maintenance work described below must be performed regularly and properly in order to guarantee long service life of your brushcutter and the full functional efficiency of the safety devices as well as to prevent any form of damage.
Putting out of operation and storage If the brushcutter is not used for more than six weeks, please note the following recommendations: • Perform maintenance (see chapter "Maintenance"). • Empty the fuel tank completely and run the carburetor until dry, due to the fact that fuels can only be stored for limited period of time and also because deposits can be formed in the tank or carburetor. • Use the remaining fuel in reserve canisters for other engines or dispose of such fuel properly.
Troubleshooting Malfunction System Observation Cause/remedy Engine does not start or only starts very badly • Ignition system • Igniting spark available • No igniting spark • Defect in fuel supply system, compression system, mechanical defect (service case) • Start/Stop switch to STOP • Defect in fuel supply system, compression system, mechanical defect (service case) • Spark plug connector or ignition module defective (service case) • Spark plug defective (see chapter "Maintenance").
