OPERATION INSTRUCTIONS. BEFORE STARTING ENGINE. Ensure that you have read and understood this manual. Check engine oil level. Top up if necessary. Check fuel level and ensure fuel is free of contaminents. Do not use fuel from metal containers unless adequatly filtered. Check hydraulic oil level. - Page 14 USE OF RUBBER TRACKS Avoid excessive manoeuvring on hard, stony and uneven surfaces such as rock, gravel, etc. Avoid keeping the rubber tracks in direct sunlight for more than 3 months. Avoid excessive steering manoeuvres on asphalt and concrete surfaces since these cause excess pad wear.
- Page 15 Use the variable width lever to fully expand the width of the tracks to their outermost position. Pushing the lever forwards will expand the track base. TRACK WIDENING Take care when widening or narrowing the tracks. Obstacles e.g. stumps, walls etc, could cause unnecessary wear to the rubber tracks and its mechanism and could also cause a track to come off.

Page 17: Emergency Stopping
Careful attention should be paid when cutting at ground level to avoid the cutter making contact with large stones or solid objects that may be unearthed by the grinding process. When such objects are identified the cutting /grinding process should be stopped, the machine switched off with the ignition key removed and the objects removed from the cutting area before the cutting / grinding process is restarted. - Page 18 Radio Control (option) Unauthorized tampering with the radio control system automatically invalidates warranty The radio control unit is highly sophisticated and offers fine control to the movements of the machine. Fine tuning of the controls can be made only by a qualified technician or under his instruction.

Failure to do so will result in the invalidation of the warranty and may result in damage to the grinder, personal injury or even loss of life. - Page 21 Belt Tightening. The Predator 28 and 38 are belt drive machines, so all the power from the engine is transferered through the belts. For this reason it is essential to keep the belts in good condition and at the correct tension at all times. LOOSE BELTS WILL WEAR OUT THE BELTS AND THE PULLEYS NOTE New belts will need tightening within the first 10 hours of use.
- Page 22 Check tracks for correct tensioning and damage. Check condition of cutters. Make sure that all cutter retaining bolts are tight and that there is no debris that may break loose when the cutter is started. Make sure wheel is tight, there is no wobble and it turns freely.
