Safety Instructions
1. Read and understand the instructions of the machine in this manual and the
engine manual (if applicable). Different models may have different parts and
controls.
2.
Equipment should only be operated by trained personnel, in good physical
condition and mental health (not fatigued). The operator and maintenance
personnel must be physically able to handle the bulk weight and power of this
machine.
3. This is a one person machine. Maintain a safe operating distance to other
personnel. Remember - one machine, one operator.
4. This equipment is intended for industrial and commercial
use. For residential use please refer to our S460.
5. For the operators safety and the safety of others, always keep all guards
and shrouds in place.
6. Never start or run the machine when unattended.

8. Never start or run the machine with the handle folded or when the disks are
not in contact with the surface.
9. Do not lend or rent the machine without the operating instructions for the
machine (and the engine, if applicable).
10.
Wear clothing suitable for the job and for the work place including,
safety shoes, hard hat, hearing protection, non-fogging vented safety
goggles, and a suitable dust mask.
11.
Keep body parts and any loose clothing away from moving parts. Failure
to comply could result in bodily harm.

Operating Instructions
1.
Wear clothes suitable for the job and work place including; safety
boots, hard hat, hearing protection, non-fogging vented safety goggles
and a dust respirator.
2. Ensure all equipment is tested and tagged prior to use on any job.
3. WARNING: Inspect the entire area to be ground before grinding to remove
any bolts or concrete nails (etc.) that could damage diamond tooling or the
machine, causing a hazardous situation.
4. Ensure there are no obstacles or existing structures that could present a
hazard to the operator. If so, take necessary action to eliminate hazards.
5. To change the polishing pads; Fold handle into the tooling mode (see Handle
Positions) and lock in place using the locking lever, then tilt machine back
so that the handle is resting on the floor.
6. The metal bond and resin pads replacement can be fast finished with the
help of a straight screwdriver
7. Install appropriate diamond tooling or other available tooling onto the
machine. Failure to comply could result in bodily injury.
8. Tilt the machine back onto the disk and lock the handle into the best position
In the operate mode for grinding comfort. (See Handle Positions)
9.
Connect the machine to a suitable power outlet. Only use heavy duty
power leads suitable for high current use (minimum 415v 4mm² cable),
no longer than 40 meters.
10. If no power is available within the specified distance, have a qualified
person install a suitable power outlet closer to your work. Alternatively
use a minimum 415v 6mm² cable for up to 60 meters.
11. Connect a suitable dust extractor to the machine via a 50mm flexible
hose. The machine is designed to take the standard 50mm
hose ends to make connection of dust extractors easy and hassle free.
12. Keep machine clear of drainage pits and grates or any such hazard.
Failure to comply could result in bodily injury and or could damage the
machine or property.
13. Ensure machine is on a level surface and handle is not folded (see
Handle Positions).

14.
Switch on the dust extractor when grinding
15. Hold the handles firmly and switch the machine on by starting the emergency
stop button, forward and reverse button.
16. This machine is designed to operate with the pads in contact with the
floor at all times. Do not operate with the diamond pads off the floor.
17. Do not attempt to make any adjustments while the machine is in
operation. Any adjustments must only be performed when machine the is
stopped and power disconnected.
18. In the event of the machine pulling to one side all the time; adjust the
axle height to obtain the best result. (at the rear of the machine).
19. After a few minutes of grinding check the wear of the diamond tooling.
If the diamonds are wearing out fast due to soft concrete / abrasive concrete it
may be necessary to change to a harder bond diamond.
20.
If LVA/LVD/LVN/LVS shows on the control panel, it indicates machine has low
voltage (lower than 350V) or overloading. At this time, you should check if the
leads are hot or if the breaker has tripped.
For a lead length of less than 40m, use 415v 4mm² cable.
For a lead length between 40-60m, use 415v 6mm² cable.
For the breaker, make sure breaker at least C40.
For overloading, take off the additional weight or slow down the speed.
21.
When Orp shows on control panel, it means the active wire has come loose.
It can be at the mains or the grinder’s 3 phase plug.
22. When GFF shows on control panel, it indicates the earth wire in the motor’s
electric box has come loose.
23. When you see OCA shows on control panel, it indicates one of the three active
wires has come loose. It can be between the inverter output and the motor
connection or inside the motor electric box.
24.
All Shark grinders must have the gear oil changed after running 500 hours
(2-3 months) for the first time, later each 1500 hours (5-6months). Gear oil -
Castrol Universal 80W-90. Volume 6 ltrs.
25. Place machine slowly and gently back to floor surface during transportation or
after changing diamond pads.
26. All plates should be cleaned daily which will prolong the oil sealer span.
27. Check gear oil depth weekly with the deep stick. Add more when oil is lower than
the stick guage

Error Code Cause Remedy
GFF
Ground Fault
Ground fault protection circuit action.
When ac motor drives measure the output
ground and the grounding power is more
than 50% than the rated current of ac
motor drive.
Note: The protection system aims at ac
motor driver instead of the human body.
1.Check if there is a short circuit
phenomenon or ground connection.
2.Confirm if IGBT power modules are
damaged or not.
3. Check the connection of side is
defective insulation or not.
LVA/LVN
Lvat Accel
The voltage of ac motor drive measuring
internal dc high voltage side is lower than
06-00 when accelerating.
1. Check if the input power and voltage
are normal or not.
2. Check if there is a sudden heavy load.
Orp
Phase Lacked
Phase lacked protection
1. Check the input power correct or not.
2. Check if machine is larger than 40HP.
If yes, check AC breaker is melting or not.
