BEF275-1
Operating Manual
STARTING WORK
Check the following prior to starting the equipment
- Check the condition of the cutter drum assembly
- Check all nuts and bolts for tightness
- Check the drive belt condition and tension
- Check the drive pulleys are clean and undamaged
- Check the engine oil level
- Check the air filter is clean
1. Before starting the machine, ensure the cutter drum assembly is clear of the ground.
2. Adjust the handlebars to a comfortable height and position.
3. Connect the dust control hose if a vacuum is being used
4. Start the engine. See manufacturers manual for further guidance
Slowly rotate the hand wheel until the cutters make contact with the surface to be prepared. It is
essential that the cutters are not lowered too far and too hard onto the surface as serious damage
could be caused to the machine and the cutter drum assembly.
5. Lock the hand wheel using the locking screw when the correct cutting depth is set.
GENERAL OPERATION
The cutters must be allowed to "float" on the cutter shafts without downward pressure. This
floating action allows the cutters to perform as the designer intended i.e. as flails rather than as
grinders or picks.
The machine should operate smoothly with a minimum of vibration. When the depth of cut
is correctly set, very little effort should be required to operate the machine backwards and
forwards - the recommended method of operation.
Excessive downward pressure on the cutters may marginally improve the work rate/finish but the
definite increase in wear rates on the cutter drum assembly and machine components is the
negative result. Remember two light passes are quicker and more cost effective than one slow
heavy pass. Tests have proven conclusively that a heavy downward pressure reduces the cutter
and drum life by over 50%.
The BEF275 is normally operated in a forward direction, the operator varies the speed of travel to
determine the final finish having already pre-set the depth control. It is recommended to operate
the machine with a backwards and forwards action, while maintaining overall forward motion.
Each pass should be overlapped to produce a uniform finish.
