  • Never apply the brush cutter within a segment between 12 and 2 o'clock.
  • Never apply this segment of the brush cutter blade to solids, such as bushes and trees, etc., having a diameter in excess of 3cm or the brush cutter will be deflected at great force with the risk of injuries.

Kickback prevention

To avoid kickbacks, observe the following:

  • Operation within a blade segment between 12 and 2 o'clock presents positive hazards, especially when using metal cutting tools.
  • Cutting operations within a blade segment between 11 and 12 o'clock, and between 2 and 5 o'clock, must only be performed by trained and experienced operators, and then only at their own risk.

Easy cutting with almost no kickback is possible within a blade segment between 8 and 11 o'clock.

Cutting Tools

Employ only the correct cutting tool for the job in hand.

Inspection and Refill of Engine Oil

-Perform the following procedure, with the engine cooled down.
- While keeping the engine level, remove the oil gauge, and confirm that the oil is filled within the upper and lower limit marks.

When the oil is in short in such a way that the oil gauge touches the oil only by its tip, in particular with the oil gauge remaining inserted in the crankcase without screwing-in (Fig. 1), refill new oil near the port (Fig. 2).

-For reference, the oil refill time is about 10h (10 times or 10 tanks of oil refill).
-If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P 18)

Recommended oil: SAE 10W-30 oil of API Classification, Class SF or higher (4-stroke engine for automobile)

Oil volume: Approx. 0.08L

Note: If the engine is not kept upright, oil may go into around the engine, and may be refilled excessively. If the oil is filled above the limit, the oil may be contaminated or may catch fire with white.

Point 1 in Replacement of Oil "Oil Gauge"

  • Remove dust or dirt near the oil refill port, and detach the oil gauge.
  • Keep the detached oil gauge free of sand or dust. Otherwise, any sand or dust adhering to the oil gauge may cause irregular oil circulation or wear on the engine parts, which will result in troubles.
  • As an example to keep the oil gauge clean, it is recommended to insert the oil gauge on its knob side into the engine cover, as shown in Fig.3.

MAKITA EM4250CA - Point 1 in Replacement of Oil "Oil Gauge" - 5

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 spilt oil before start of operation.

REFUELING

Handling of Fuel

It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refueling must be performed in a sufficiently ventilated room or in the open air. Never inhale fuel vapor, 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 enters 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 up within a period of 4 weeks, even if it is kept in a special container in a well-ventilated shade. If a special container is not used or if the container is not covered, 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 the cabin or trunk.

Fuel

The engine is a four-stroke engine. Be sure to use an automobile gasoline (regular gasoline or premium gasoline).

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 startup.

Refueling

WARNING: INFLAMMABLES STRICTLY PROHIBITED

Gasoline used: Automobile gasoline (unleaded gasoline)

-Loosen the tank cap a little so that there will be no difference in atmospheric pressure.
- Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that the refuel port will be oriented upward. (Never refill fuel full to the oil refill port.)
-Wipe well the periphery of the tank cap to prevent foreign matter from entering into the fuel tank.
-After refueling, securely tighten the tank cap.

  • If there is any flaw or damage on the tank cap, replace it.
  • The tank cap is consumable, and therefore should be renewed every two to three years.

NYLON CUTTING HEAD

The nylon cutting head is a dual string trimmer head capable of both automatic and bump & feed mechanisms.

The nylon cutting head will automatically feed out the proper length of nylon cord by the changes in centrifugal force caused by increasing or decreasing rpms. However, to cut soft grass more efficiently, bump the nylon cutting head against the ground to feed out extra cord as indicated under operation section.

Operation

-Increase the nylon cutting head speed to approx. 6,000/min.
Low speed (under 4,800/min) is not suitable, the nylon cord will not feed out properly at low speed.
- The most effective cutting area is shown by the shaded area.

If the nylon cord does not feed out automatically proceed as follows:

  1. Release the throttle lever to run the engine idle and then squeeze the throttle lever fully. Repeat this procedure until the nylon cord feeds out to the proper length.
  2. If the nylon cord is too short to feed out automatically with the above procedure, bump the knob of the nylon cutting head against the ground to feed out the nylon cord.
  3. If the nylon cord does not feed out with procedure 2, rewind/replace the nylon cord by following the procedures described under "Replacing the nylon cord".

Replacing the nylon cord

-First,stop the engine.
-Press on the housing latches inward to lift off the cover, then remove the spool.

  • Hook the center of new nylon cord into the notch in the center of the spool, with one end of the cord extending about 80mm (3-1/8") more than the other. Then wind both ends firmly around the spool in the direction of the head rotation (left-hand direction indicated by LH and right-hand direction by RH on the side of the spool).
  • Wind all but about 100mm (3-15/16") of the cords, leaving the ends temporarily hooked through a notch on the side of the spool.
  • Mount the spool in the housing so that the grooves and protrusions on the spool match up with those in the housing. Keep the side with letters on the spool visible on the top. Now, unhook the ends of the cord from their temporary position and feed the cords through the eyelets to come out of the housing.

-Perform the following work daily after use:

  • Clean the Brush cutter/Grass trimmer externally and inspect for damage.
  • Clean the air filter. When working under extremely dusty conditions, clean the filter the several times a day.
  • Check the blade or the nylon cutting head for damage and make sure it is firmly mounted.
  • Check that there is sufficient difference between idling and engagement speed to ensure that the cutting tool is at a standstill while the engine is idling (if necessary reduce idling speed).

If under idling conditions the tool should still continue to run, consult your nearest Authorized Service Agent.

  • Check the functioning of the I-O switch, the lock-off lever, the control lever, and the look button.

REPLACEMENT OF ENGINE OIL

Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of replacement.

MAKITA EM4250CA - REPLACEMENT OF ENGINE OIL - 1

ATTENTION : In general, the engine main unit and engine oil still remain hot just after the engine is stopped. In replacement of oil, confirm that the engine main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of scald.

Note: If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.

Interval of replacement : Initially, every 20 operating hours, and subsequently every 50 operating hours

Recommended oil : SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)

In replacement, perform the following procedure.
1) Confirm that the tank cap is tightened securely.

THINGS YOU SHOULD KNOW ABOUT THE EMISSION CONTROL SYSTEM WARRANTY

MAINTENANCE AND REPAIRS

You are responsible for the proper use and maintenance of the engine. You should keep all receipts and maintenance records covering the performance of regular maintenance in the event questions arise. These receipts and maintenance records should be transferred to each subsequent owner of the engine. Makita reserves the rights to deny warranty coverage if the engine has not been properly maintained. Warranty claims will not be denied, however, solely because of the lack of required maintenance or failure to keep maintenance records.

MAINTENANCE, REPLACEMENT OR REPAIR OF EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY REPAIR ESTABLISHMENT OR INDIVIDUAL; HOWEVER, WARRANTY REPAIRS MUST BE PERFORMED BY A DEALER OR SERVICE CENTER AUTHORIZED BY Makita. THE USE OF PARTS THAT ARE NOT EQUIVALENT IN PERFORMANCE AND DURABILITY TO AUTHORIZATION PARTS MAY IMPAIR THE EFFECTIVENESS OF THE EMISSION CONTROL SYSTEM AND MAY HAVE A BEARING ON THE OUTCOME OF A WARRANTY CLAIM.

If other than the parts authorized by Makita are used for maintenance replacements or for the repair of components affecting emission control, you should assure yourself that such parts are warranted by their manufacturer to be equivalent to the parts authorized by Makita in their performance and durability.

HOW TO MAKE A CLAIM

All repairs qualifying under this limited warranty must be performed by a service dealer authorized by MAKITA. In the event that any emission-related part is found to be defective during the warranty period, you shall notify MAKITA at the following contacts and you will be advised of the appropriate warranty service dealer or service providers where the warranty repair can be performed.
