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.

Operating Instructions
1.
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.

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.

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.
21.
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.
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
14.
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.
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.
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.
