Operating instructions

1. Wear clothes suitable for the job and for the work place including, safety shoes, hard hat, hearing protection, non-fogging vented safety goggles, and dust respirator suitable for dust.
2. WARNING! POISONOUS EXHAUST GASES. Do not operate petrol powered equipment without adequate ventilation. Carbon monoxide is an invisible odorless gas that can harm or can kill you.
3. Be sure all equipment is tested and tagged prior to use on any job.
4. Inspect entire area to be ground before grinding and remove any bolts or concrete nails (etc.) that could damage diamond tooling or machine which could cause a hazardous situation.
5. Ensure there are no obstacles or existing structures that could present a hazard to the operator. If so, take necessary action to eliminate the hazard.

8. 
9. Inspect and install appropriate tooling and tighten using the left hand nuts. One at a time.
10. Tilt machine back onto its wheel in the opposite manner to above.
11. Wind the height adjustment knob fully clockwise and pull the fast raise lower lever towards you.
12. Connect machine to suitable power outlet. Only use heavy duty power lead suitable for high current use (minimum 2.5 mm² cable), no longer than 20 meters. (For petrol powered equipment, refer to engine manual for startup procedure).
13. If no power is available within the specified distance, have a qualified person install a suitable power outlet closer to your work. Alternatively use 4mm² cable for up to 50 meters.
14. Connect a suitable dust extractor to the machine via a 50mm flexible hose. The machine is designed to take the standard FLOOREX 50mm hose ends to make connection of dust extractors easy and hassle free. Alternatively, water spray using the supplied water connection point can be used to suppress dust.
15. 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.
16. Switch on the dust extractor or water spray.
17. Hold the handles firmly and switch the machine on by pushing the green button. Or start the petrol engine.
18. If the over-current device trips it indicates a problem. (Undersize power lead or poor power to GPO outlet). Refer above for recommendations on power leads. Rectify problem or decrease load on grinder by using tooling with more surface area. Continuing to use the MASTIFF 200 when constant tripping occurs, VOIDS THE WARRANTY!
19. This machine is designed to operate with the wheels in contact with the floor at all times. Do not operate with wheels off the floor.
20. Push the fast raise lower lever forward then wind the depth control anti clockwise to lower to tools onto the floor.
21. Once the tools start touching the floor you can rotate the hand wheel a total of 4 more turns for maximum cut depth.
22. This equates to a maximum cutting depth of around 3-4mm. Lowering the machine father will risk damaging the drum and fails and shafts.
