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 engine oil level
- Check air filter is clean
1. BEFORE starting the machine ensure the cutter drum assembly is clear of the ground. If not
adjust using hand wheel.
2. ENSURE the drive control levers are in the non-drive/neutral (central) position and speed
control knob is turned to OFF position.
3. Connect vacuum hose to dust port at side of machine if dust control vacuum is being used.
4. START the engine – see operators manual
5. OPERATE the hydraulic lift/lower lever allowing the machine to fall to its lowest position
6. SLOWLY rotate the hand wheel until the cutters make contact with the surface to be treated.
7. Push both drive control levers forward and slowly open the speed control knob until machine is
moving at satisfactory speed.
8. Adjust hand wheel to desired cutting depth and engage hand wheel locking pin.
9. To raise and lower machine use hydraulic lift lever to the left of hand wheel.
10. 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.

Operating Manual
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.
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.
This manual should be read in conjunction with the owners manual of the petrol engine. The
engine is designed to give safe and dependable service if operated according to the instructions.
Read and understand the owners manual before operating the engine. Failure to do so could
result in personal injury or equipment damage.
DUST CONTROL
To control any dust created by the operation connect an industrial dust collector or vacuum to the
50mm port at the side 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.

MAINTENANCE
PRIOR TO ANY MAINTENANCE OR ADJUSTMENT STOP ENGINE.
After use: Clean the machine to remove all build up of dust and surface residues.
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, engine 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 engine. 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 engine if the belts
are excessively tight.
Note: Never operate the BEF320 without belt guard fitted

SAFETY
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 engine and set the height
adjustment fully up before leaving 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.
Never operate the BEF320 inside or in a poorly ventilated area. Carbon monoxide gas is emitted..
Always stop the engine before refuelling.
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 24). 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.
