DFG400-5 & 5DP
COMPACT FLOOR GRINDER
Operating Manual
STARTING WORK
Check the following prior to starting the equipment.
Check all nuts and bolts for tightness
Check the drive belt condition and tension
Check the plugs and cables for damage
1. Before starting work, check that the set up of the machine and the grinding heads has
been completed as described below to ensure even wear to the heads.
2. It is vital at this stage that the machine should be set to grind the floor along the same
plane. Incorrect set up will result in uneven head wear, vibration and damage to the flexible
couplings that support the heads.
3. Raise the dust skirt by approximately 20mm and check that the grinding heads are in full
contact with the floor surface.
4. With the machine set on the floor surface to be ground, check the level of the floor with a
spirit level. Then place the spirit level on the side of the machine above the dust skirt.
Adjust the rear wheel height using the hand wheel (part no 9135), until the level of the
machine is the same as the floor level.
5. Push the dust extraction skirt down to the floor surface.
6. 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.
7. Ensure that the power supply is correct for the machine (see page 2 for further details).
Connect the machine to the power supply.
8. To start the machine
Lift the grinding heads slightly by tipping the machine onto its rear wheels.
Turn the switch (Part no 9254) on the electric panel, to the start position and hold for 2 - 3
seconds, then release the switch to the run ‘1’ position.
Lower the machine onto the floor, moving the heads evenly across the surface to ensure a
smooth ground finish.
9. To stop the machine, turn the switch on the panel to the off position.
Never allow the machine to stop moving whilst grinding heads are in contact with the
surface
