Safety Precautions ■ In order to ensure proper and safe operation of your brushcutter • Read this Owner/Operator Manual carefully. Be sure you understand how to operate this unit properly before you use it. Failure to do so could result in serious injury. • Be sure to keep this manual handy so that you may refer to it later whenever any questions arise.
Safety Precautions ■ Work gear and clothing ■ Warnings considering handling of fuel • When using your brushcutter, always be sure to wear strong, durable, work clothing; shirts should be long-sleeved shirts and pants should be full-length pants reaching down to the ankles. • The engine of the RedMax® brushcutter is designed to run on a mixed fuel which contains highly flammable gasoline.
Safety Precautions ■ Things to check before using your brushcutter ■ Things to check before starting up the engine • Before beginning work, look around carefully to get a feel for the shape of the land, grass to be trimmed, and whether or not there are any obstacles which might get in the way while working, and remove any obstacles before beginning work.
Safety Precautions ■ Things to be careful about when using your brushcutter • When using your brushcutter, grip the handles of the brushcutter firmly with both hands, place your feet slightly apart (slightly further apart than the width of your shoulders) so that your weight is distributed evenly across both legs, and always be sure to maintain a steady, even posture while working.
Safety Precautions ■ Notes on care and maintenance of your brushcutter • In order to maintain your brushcutter in proper working order, perform the maintenance and checking operations described in this manual at regular intervals. In the event that any parts must be replaced or any maintenance or repair work not described in this manual must be performed, please contact a representative from the store nearest RedMax authorized servicing dealer for assistance.
Set up ■ MOUNTING ENGINE (BC2300DL & BC2600DL) 1. Remove the clamp temporarily attached to the clutch housing. 2. Push the driveshaft toward the gearcase and rotate it by hand to check that the driveshaft is engaged with the gears. 3. Insert the shaft tube into the clutch housing until it bottoms. When difficult to engage, twist the engine slightly. 4. Align the positioning holes on the clutch housing and the shaft tube and fit the boss on the clamp into the holes. Fasten the clamp securely.
Set up ■ CONNECTING SWITCH WIRES • Connect the switch wires between the engine and the main unit. Pair the wires of the same color. ■ PUTTING ON WAIST PAD (BC4400DW only) • Warp the waist pad around the shaft tube and the throttle wire. ❲ 10 ❳ ■ INSTALLING CUTTING HEAD 1. While locking the gear shaft by inserting the attached bar into the upper holder and the gear box, loosen and remove the hexagon bolt(left-handed) 2. Fit the spacer attached to the head assembly between the upper and lower holders.
Fuel WARNING • Gasoline is very flammable. Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refueling the unit. Select outdoor bare ground for fueling and move at least 3m(10ft) away from the fueling point before starting the engine. • The RedMax engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use.
Operation WARNING 4. Shift the ignition switch to the START position. • Keep bystanders and animals at least 50 feet (15m) away from the operating point. If you are approached, immediately stop the engine. ■ STARTING ENGINE 1. Rest the unit on a flat, firm place. Keep the cutting head off the ground and clear of surrounding objects as it will start rotating upon starting of the engine. 2. Pump the primer until fuel flows out in the clear tube. 3. Move the choke lever upward to close the choke. 5.
Operation WARNING • The product is equipped with a centrifugal clutch mechanism, so the cutting attachment begins to rotate as soon as the engine is started by putting the throttle into the start position. When starting the engine, place the product onto the ground in a flat clear area and hold it firmly in place so as to ensure that neither the cutting part nor the throttle come into contact with any obstacle when the engine starts.
Operation 2. Use full throttle when cutting. 3. You can avoid thrown debris by sweeping from your left to the right. 4. Use a slow, deliberate action to cut heavy growth. The rate of cutting motion will depend on the material being cut. Heavy growth will require slower action than will light growth. 5. Never swing the unit so hard as you are in danger of losing your balance or control of the unit. 6. Try to control the cutting motion with the hip rather than placing the full workload on the arm and hands.
