STARTING WORK
CHECK the following prior to starting the equipment:
- Check condition of cutter drum assembly
- Check all bolts for tightness
- Check drive belt condition and tension
- Check drive pulleys are undamaged and clean
- Check all leads, pipes and hoses for damage
- Check electrical cables/plugs
- Check RCD protection is fitted and working
1. Ensure power supply is correct. BEF320-1A requires a 380/415v 32amp supply from the
mains or generated by a minimum of 25kva on 50 cycles.
2. After connecting the machine to the power supply turn the red isolator (on the front of
electric panel) to the on position. Red light will illuminate on panel.
3. BEFORE starting the machine ensure the cutter drum assembly is clear of the ground. If
not adjust using hand wheel.
4. ENSURE the drive control levers are in the non-drive/neutral (central) position and speed
control knob is turned to OFF position.
5. Connect vacuum hose to dust port at side of machine if dust control vacuum is being used.
6. START the electric motor using the green button on top of the electric panel. Check that the
three phase power supply is phased to suit the machine. The electric motor should be turning
in direction of arrow on cooling fan cover ie clockwise when viewed from the non drive side of
machine. If not the electric motor will be turning in reverse and hydraulic drive systems will not
operate. (To reverse phases see page 3).
7. OPERATE the hydraulic lift/lower lever allowing the machine to fall to its lowest position
8. SLOWLY rotate the hand wheel until the cutters make contact with the surface to be
treated.
9. Push both drive control levers forward and slowly open the speed control knob until
machine is moving at satisfactory speed.
10. Adjust hand wheel to desired cutting depth and engage hand wheel locking pin.
11. To raise and lower machine use hydraulic lift lever to the left of hand wheel.
12. To turn machine around at end of run raise out of cut, reduce forward speed and pull
either drive control lever back through neutral and into reverse. Pulling the left lever will make
machine turn left and the right one turn right.

GENERAL OPERATION
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
cutters rather than as grinders or picks. Do not pull the control levers into reverse when cutting
as this could result in the machine reversing quickly in an uncontrolled manner.
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.
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 heavy downward pressure reduces
cutter and drum life by over 50%.
The BEF320 should always be 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 that the machine is not operated in reverse whilst the cutters are in contact with
the surface. When lifting the cutter drum from the work surface it is not necessary to turn the
hand wheel - lift upwards by simply operating the hydraulic lift lever.
Always use the shortest possible length of extension cable. To avoid voltage drop the cable
must be a minimum of 6mm. Maximum length of cable can then be up to 75 metres.
The motor is fitted with thermal overload protection. Should the thermal trip be activated then
it must be allowed to cool and reset. Almost without exception if a motor trips out it is an
indicator of a fault elsewhere either on the machine or with the power supply or simply that the
machine is being overloaded.
Note: the thermal trip on the motor is a fail safe device and is not intended to be
continuously reset.
If the motor repeatedly cuts out then it will be damaged.
Possible causes are: An inadequate or faulty power supply.
Overloading of the machine.
Mechanical fault on the machine e.g. bearing or cutter drum failure.
The machine can only be overloaded by setting the depth of cut to low. When overloaded the
machine can vibrate which will in turn damage the electrical switch components.
The electric control panel is fitted with two safety devices which further protect the motor from
damage. The switches are set by the manufacturer and under no circumstances should be
adjusted.

DUST CONTROL
To control any dust created by the operation connect an industrial dust collector or vacuum to
the 50mm port at the rear of the machine. We recommend the SPE 316 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.)
PHASE REVERSING
If the electrical motor is turning anti clockwise when viewed from the non drive end and the
hydraulic drive system is not working the power supply to your BEF320 is incorrectly phased.
The correct carry out the following.
1. Isolate power supply.
2. Open electric panel door.
3. Turn phase reverse switch to opposite position.
4. Close panel door.
5. Re connect power supply and retest.
Note: If machine is still turning in reverse seek advice of qualified electrician.
The BEF320 machine should always be moved by its own hydraulic power driven system as
pushing the machine continually around by hand could result in internal damage to the
hydraulic motor and pump system.

MAINTENANCE
PRIOR TO ANY MAINTENANCE OR ADJUSTMENT ISOLATE POWER SUPPLY AND
STOP EQUIPMENT
After use: Clean the machine to remove all build up of dust and surface residues. If using a
hose pipe or pressure washer take care that water is not directed onto electrical components
and switches.
Note: Motors and switches are not waterproof
Drum Removal:
Remove bolts on side plate and then screw two bolts back into the two tapped holes in the side
plate. Continue winding in and this will push side plate off dowel pins. Pull off side plate,
remove key from shaft. Pull out cutting drum. Fitting a new cutter head is simply a reversal of
the above procedure, a little care must be taken to align the drive shaft, cutter drum and
support end drive bush.
EXCESSIVE FORCE SHOULD NOT BE NEEDED TO REFIT THE CUTTER DRUM.
Cutter Drum Maintenance:
When changing cutter drum always check that the flail shafts are not worn with pronounced
grooves and also that the centres of cutters and spacers are not elongated and beginning to
"mushroom". The drum assembly is hitting concrete with great force 650 times every minute!
Expenditure on consumables must be expected and built into all job costing.
While changing the drum the condition of the drive shaft and side plate bearings should be
checked. If any roughness, side play or leakage of grease is detected then new bearings
should be fitted. Lightly oiling the drive shaft will prevent a build up of rust which could cause
difficulty when changing the drum. At the same time check belt tension and condition also
checking the pulley grooves are clean and undamaged.
The drive shaft is manufactured from high quality steel to produce the special properties
required. The shaft is extremely strong and virtually unbreakable when used as intended. If
however sideways pressure is exerted on the shaft while it is not supported by the side plate
bearing it can be bent.
With the drum removed check that the vacuum port is free from blockages and that the dust
skirts are in good condition.
Remove all build up and deposits of material from the under side of the drum housing. On
certain applications, e.g. the removal of damp self levelling compounds, it may be necessary
to clean away deposits hourly! Failure to do so could result in overload of the drum assembly,
drive motor and drive belts

Height Adjustment Maintenance:
Ensure the height screw thread is cleaned and then lightly oiled. Periodically it should be
removed and the female threaded section cleaned out and oiled. At the same time the self-
aligning bearing should be greased.
The clevis pin should be oiled regularly to maintain a light, smooth height adjustment.
BEF320 Cutter Drum Adjustment:
Should the machine be cutting more heavily on one side. Stop machine and isolate power
supply, adjust lock nut/bolt assembly on top of right hand side of chassis. By adjusting up or
down the cutting action can be reset level again. Retighten all bolts. Test on sample area and
if required reset until cutting correctly.
Great care should be taken to ensure belts have correct tension and also correct alignment.
Serious damage could be caused to the drive shaft, drive shaft bearings and drive motor if the
belts are excessively tight.
Note: Never operate the BEF320 without belt guard fitted

SAFETY
In the interest of site safety the BEF320 should never be operated unless some form of
residual current circuit breaker is fitted (RCD).
Only trained operatives should be allowed to work the BEF320.
All operatives should wear ear defenders, goggles and an effective dust mask.
Note: It is possible that the noise level produced by the BEF320 could exceed 90dbA.
Personal noise protection must be worn.
To control dust it is recommended that an SPE dust control unit/vacuum is fitted.
Never leave the BEF320 unattended while in use. Always stop the motor and raise the height
adjustment fully up before leaving the machine.
Always ensure that all power leads and hoses are disconnected before attempting to service
the machine. Never remove the side plate or belt guard until the cutter drum has come to a
complete standstill. Never tip the machine backwards until the cutters have come to rest.
The BEF320 should never be used in wet/damp conditions and should be stored under cover
and kept dry at all times.
Noise and vibration will occur at various levels dependant on the attachments and work
being completed. SPE have assessments conducted under test conditions detailed in the
operating manual. (See page 26). However it is recommended that additional tests are
taken on site to provide the operator with accurate information on using the equipment
within the guidelines laid down by the health and safety executive.
