Never place the throttle into the high speed
position when starting the engine.

2. After starting the engine, check to make sure

that the cutting attachment stops rotating when
the throttle is moved fully back to its original
position. If it continues to rotate even after the
throttle has been moved fully back, turn off the
engine and take the unit to your authorized Red
Max servicing dealer for repair.

USING THE PRODUCT

Cut only materials recommended by the
manufacturer. And use only for tasks explained
in the manual. 

1. Grip the handles firmly with both hands using

your whole hand. 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.

2. Keep cutting attachment below waist level. 
3. Maintain the speed of the engine at the level

required to perform cutting work, and never raise
the speed of the engine above the level
necessary.

4. If the unit start to shake or vibrate, turn off the

engine and check the whole unit. Do not use it
until the trouble has been properly corrected.

5. Keep all parts of your body away from rotating

cutting attachment and hot surfaces.

6. Never touch the muffler, spark plug, or other

metallic parts of the engine while the engine is in
operation or immediately after shutting down the
engine. Doing so could result in serious burns or
electrical shock.
