SAFETY
Only trained operatives should be allowed to work the DFG280 floor grinder.
All operatives should wear ear defenders, goggles and an effective dust mask. Note: It is
possible that the noise level produced by the DFG280 could exceed 90dbA. Personal noise
protection must be worn and the equipment must be used in line with guidelines laid down
by the Health & Safety Executive.
Never leave the DFG280 unattended whilst in use. Always stop the motor prior to leaving
the machine.
Keep the electric lead away from the grinding head.
Always use the correct voltage for the machine and RCD protection.
Always ensure that all power leads are disconnected before attempting to service the
machine. The service of electrical components should be carried out by authorised
personnel. Never tip the machine completely backwards until the grinding plates have
stopped rotating, just raise slightly.
Vibration will occur at various levels dependent on the attachments and work being
completed. It is recommended that tests are taken on site to provide the operator with
accurate information on using the equipment within the guidelines laid down by the Health &
Safety Executive.
Never operate the machine without a dust skirt.
NOTE:
NEVER OPERATE THE COMPACT FLOOR GRINDER IN WET CONDITIONS AS
ELECTRICAL COMPONENTS ARE NOT WATERPROOF

SAFETY PRECAUTIONS
DANGER
EXPLOSION HAZARD
Never operate the machine in an explosive
atmosphere, near combustible materials, or where
ventilation does not clear exhaust fumes.
WARNING
BURN HAZARD
Never come into contact with the engine or muffler
when engine is operating or shortly after it is turned
off. Serious burns may occur.
CAUTION
MOVING PARTS
Before starting the machine, ensure that all guards
and safety devices are in place and functioning
properly.
ATTENTION
READ OWNER’S MANUAL
Read and understand owner’s manual before using
this machine. Failure to follow operating
instructions could result in serious injury or death.

DFG280 OPERATING MANUAL
This manual covers, to the best of our knowledge, the operation and maintenance of the
DFG280. Before operation of the equipment the manual should be read and understood by the
operator. The safety regulations must be followed at all times. Service of electrical
components should be carried out by authorised personnel. Failure to follow these instructions
could result in damage to the machine and/or serious personal injury or death.
WARNING
Failure to follow these instructions may result in serious personal injury or death. SPE
disclaims all responsibility for damage to persons or objects arising as a consequence of
incorrect handling of the machine and failure to inspect the machine for damage or other faults
that may influence the operation prior to starting work.

STARTING WORK
Check the following prior to starting the equipment.
•Check all nuts and bolts for tightness
•Check the plugs and cables for damage
1. The machine is fitted with an adjustable handle which can be folded over for ease of
lifting and transportation. The handle can be adjusted by releasing the two locking pins on
the side and moving the handle into one of three positions for preferred operator comfort.
This is then locked in place by re-engaging the locking pins.
2. Fit a suitable grinding head by tilting the machine backwards on to its handle. The
machine must be secured and supported. Attach the grinding head to the machine using the
four countersunk fixing screws and tighten. Lower the machine back to the upright position.
3. Connect the vacuum hose to the dust extraction port, if a dust control vacuum is being
used. We recommend the SPE VAC316 3 motor vacuum for dust control.
4. Ensure that the power supply is correct for the machine (see page 11 for further details).
Connect the machine to the power supply.
5. To start the machine
•Check that the stop button is out by rotating clockwise.
•Lift the grinding head slightly by tipping the machine onto its rear wheels.
•Press the start button.
•Lower the machine onto the floor, moving the head evenly across the surface to
ensure a smooth ground finish.
6. To stop the machine, push the red stop button.
7. The machine is also fitted with two removable panels in the dust shroud which can assist
with edge work. Undo the two thumb nuts and remove the panel to allow the grinding head
to get closer to the vertical surface. Once done, replace the panel and refit and tighten the
two thumb nuts.
Never allow the machine to stop moving whilst grinding head is in contact with the
surface.

GENERAL OPERATION
Although excessive downward pressure on the cutters may marginally improve the work
rate/finish this would increase the wear rates on the head, components and could result in
overloading the motor.
Tests have shown that two light passes are quicker and more cost effective than one slow
heavy pass and have conclusively shown that heavy downward pressure reduces the life of
the tooling discs used.
The DFG280 is normally operated in a forwards and left to right direction, the operator
varying the speed of travel to determine the final finish. It is permissible to operate the
machine with a backwards and forwards action. Each pass should be overlapped to
produce a uniform finish.

CHANGING THE GRINDING HEAD
1. Disconnect from the power supply.
2. Tilt the machine backwards on to its handle. The machine must be secured and
supported.
3. Make sure the grinding head is cool to the touch.
4. Use a hex key to undo the countersunk screws securing the Grinding Head to the adaptor
plate.
5. Remove the grinding head and replace.
6. Ensure the grinding head is seated to the adaptor plate correctly prior to tightening the
countersunk screws diagonally.
7. Lower the machine back to the upright position.
8. Reconnect to the power supply.
CHECK FOR CORRECT WEAR RATE AFTER QUARTER OF AN HOUR AND AGAIN AT
HALF AN HOUR INTERVALS - THIS WILL GIVE AN IDEA OF WEAR RATE

ELECTRICAL INSTRUCTIONS
The DFG280 machine is supplied with a specially commissioned 110V electric motor and
starter switch assembly. Each unit is fully tested and the safety overload relays have been
calibrated and set according to the manufacturers specifications. In the event of the malfunction
on a new machine the owner should first check that the power supply on site is suitable and
adequate.
DFG280-5 (110V)
•The 110V motor requires a 32 Amp supply.
•To avoid voltage drop the cable size must be a minimum of 4.0mm 3 core. Maximum
length of cable not to exceed 30 metres.
•If a transformer is used it must have a continuous rated output of at least 3 KVA. In
practice this means that a 5 KVA transformer must be used.
DFG280-1 (415V Three Phase)
DFG280-3 (230V Single Phase)
•The 230V/400V require a 16 Amp supply.
DFG280-6 (115V)
•The 115V motor requires a 15 Amp supply.
All cables should be fully uncoiled and never left wrapped around cable reels or tied in loops.
If the power is to be generated, the DFG280 requires a minimum 8kva generator.
The motor is protected with a safety trip in the panel. Should the trip be activated, it will reset
automatically after cooling down.
If the motor repeatedly cuts out then it will be damaged. The possible causes are
either an inadequate power supply, overloading of the machine, or an electrical fault.

MAINTENANCE
Prior to any maintenance or adjustment disconnect the machine from the power supply.
AFTER USE:
- Clean the machine to remove all build-up of dust and surface residue. 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)
- All components should be checked daily for tightness.
- Check the plugs and cables for damage.
- The flexible drive coupling that support the grinding head should be checked on a
weekly basis.
- Any excess vibration due to uneven head wear should result in the head being changed
to eliminate damage to coupling.
BASIC MAINTENANCE CHECKLIST
DAILY: (or every 8hrs to 10hrs)
•Check all nuts and bolts for tightness.
•Check the condition of the grinding head
•Check the plugs and cables
WEEKLY:
All the above with the following: -
•All of the above with the following.
•Check the flexible drive coupling
•Check the support wheels and grease
