UNPACKING YOUR MACHINE
Take care when removing your machine from the packaging. It weighs in excess of 25
kilos depending on the model. Seek assistance to lift it from the carton.
Your machine will arrive in two packages if you have ordered it with a magnetic chuck. For
safety reasons the chuck is packed separately from the Rotary Grinding Unit.
Inside the larger package is the Rotary Grinding Attachment, the Speed Control and there
are assorted small parts. Take care not to dispose of the small parts with the packaging.
Please re-cycle the packaging.
ASSEMBLY INSTRUCTIONS
To assemble the Chuck to the machine clean the top surface of the deflector & the
underside of the chuck. Lightly smear the cleaned surfaces with a light oil.
Remove the 3 pcs of 8mm grub screws from the deflector (these 3 pcs of 8mm screws are
for dust protection).
Gently lower the chuck onto the deflector top.
When the two ground surfaces meet gently turn the chuck to ensure good contact.
Use the supplied 3mm Allen key to evenly tighten 3 grub screws which are at the bottom of
the holes where the 8mm grubs screws were.
Use only moderate torque do not over tighten.
Replace the 3 pcs of 8mm grub screws in the deflector. Tighten them until they stop. These
screws protect the grub screws that secure the magnetic chuck from dust ingress.
Ensure your Electric supply is suitable for the Sprint Control. The supply required is single
phase. A qualified Electrician must inspect the electrical connections to the control.
A Sprint Electrical control diagram is supplied with your machine for reference.
Plug your motor in to the speed control. Your Motor control can then be connected to your
power supply.
There are two Rocker Switches and one Rotary Switch. The switched are labelled to
indicate their function.
The on/off switch illuminates when power is available to the motor.
The Direction Rocker Switch has 3 positions. The center position is off and the other 2
positions rotate the chuck in alternate directions.
The speed control regulates how fast the chuck rotates.
It is recommended that the machine is not started on full speed. Turn the rotary speed
control down to stop the machine then turn the machine on and increase the speed on the
rotary speed control.

MAGNETIC CHUCK
To operate the Magnetic Chuck insert the 6mm Allen Key into the Actuator and turn.
The magnet may be partially applied for thin work pieces.
Never leave the Allen Key in the magnet whilst the chuck rotates.
FIRST USE OF MACHINE AFTER DELIVERY
Check that the oil level is halfway up the sight glass. Connect the machine to the power
supply as described in the assembly instructions.
The magnetic chuck will require grinding true.
FLAT BASE MODEL
Contact the chuck face with a course dressed wheel and remove sufficient material to fully
clean up the face of the chuck. (Note: ensure the reversible chuck rotates contrary to the
grinding wheel). The use of coolant is recommended. Consult with your safety officer
concerning personal protection equipment.
SINE BASE MODEL
Remove the 8mm transit screw from the quadrant and replace it with the locking lever. The
'slip block' must be placed between the Sine Roller and the slip pad, ensure correct contact
is made.
Contact the chuck face with a course dressed wheel and remove sufficient material to fully
clean up the face of the chuck. (Note: ensure the reversible chuck rotates contrary to the
grinding wheel). The use of coolant is recommended. Consult with your safety officer
concerning personal protection equipment.
Refer to your inspection report for the sine centers for your model.
ANGLE GRINDING
The Sine Base Model can be set at any angle between 0-46°. A Sine Bar is fitted. It has
150mm centers. For quick angle setting a scale is engraved on the locking quadrant.
Please note that when grinding an angle the chuck will require rotating in the opposite
direction to flat grinding. When grinding on an angle it is also important that your grinding
wheel is on the center of your component. If the wheel is not on the centreline a true grind
cannot be achieved.

CARE OFYOUR MACHINE
The unit is coolant proof, apply as much coolant as required to grind your component.
However you must not allow coolant to flood up to the level of the motor cover. Ensure the
drains on your grinding machine are free off debris to allow coolant to drain away.
Change the Gearbox oil every six months with a good quality Gearbox Oil. Clean grit &
coolant from machine when not in use. Lightly oil the base & chuck prior to storage.
WARRANTY
Your machine is guaranteed parts & labor for 12 months from dispatch date.
For your warranty to remain valid all operating & care instructions must have been adhered
to.
