BEF200-1
Operating Manual
STARTING WORK
Check the following prior to starting equipment
- Check condition of cutter drum assembly
- Check all bolts for tightness
- Check drive belt condition and tension
- Check plugs and cables for damage
1. Before starting the machine ensure that the cutter drum assembly is clear of the ground by
turning the hand wheel anti clockwise to full height. The machine is now locked in position and
cannot accidentally roll away if left unattended.
2. Adjust the handlebar to a comfortable height and position.
3. Connect the power supply – See page 2 for further details
4. Connect the vacuum hose to the dust port at the rear of the machine if a dust control
vacuum is being used.
5. Start the motor by turning the switch on the panel to the start position. Hold for 2-3 seconds
for the motor to start and release. The switch will return to its run position.
6. 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 cutter drum assembly. The cutters must be
allowed to "float" on the cutter shafts without excessive 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.
GENERAL 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, machine components and
overloading the motor is the negative result.
- Remember two light passes are quicker and more cost effective than one slow heavy pass.
Tests have proven conclusively that heavy downward pressure reduces cutter and drum life by
over 50%.
- To remove dust, connect an industrial dust collector or vacuum to the 50mm port (part no
9109) at the rear of the machine. We recommend the SPE VAC316 for almost 100% dust
control. In the absence of a dust control unit it is acceptable to spray water onto the surface or
to feed water down the vacuum port. Cutter drum assembly life is increased by around 10%
when operating the machine in this way.
(Note: Electrical motors and switches are not waterproof, take care to protect them from
splashes.)
- The BEF200 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 permissible to
operate the machine with a backwards and forwards action. Each pass should be overlapped
to produce a uniform finish.
To cease operation, raise the cutter drum assembly clear of the ground and then turn the
switch to the ‘off’ position.
