22. Check cooling system before switching ON to ensure smooth flow of cooling water and the system works properly.
23. It is strictly prohibited to start drilling in the absence of cooling water.

STARTING THE CORE DRILL RIG
When the safety instructions above have been read, start the core drill rig according to the following steps:
1. Switch engine turn-off device to the ON position.
2. If cooler start, shift air valve to the CLOSED position (if heater start, air valve can be directly shifted to the OPEN position).
3. Press the fuel pump several times until there is fuel in the fuel-return tube.
4. Open the cooling valve (just small flow), to be increased when drilling.
5. Adjust throttle valve to make it in the appropriate position.
6. Adjust the machine location to ensure that the core bits (rotating part) do not contact with any objects.
7. Pull starter handle lightly, further pull until resistance to start the engine.
8. Adjust the throttle valve to enable the engine in idle state.
9. With the engine temperature increasing, shift the air valve to OPEN position.
10. Adjust the throttle valve to enable the engine speed has ideal position, lock throttle position, and you can start your work.
Note: do not apply too much pressure while drilling: push machine appropriately with a constant power.
Do not use machine in a dangerous environment. A messy work environment will lead to accidents.
4.
STOPPING THE CORE DRILL RIG
Follow the steps below to stop the core drill rigs:
1. Take out the core bits when it’s running.
2. Adjust throttle valve to enable the engine in idle state.
3. Switch engine turn-off device to the OFF position.
4. Turn off the cooling water switch.
5.
MAINTENANCE
Maintenance for core drill rigs:
1. After each use, rinse core bits immediately, and blow-dry it.
2. The machine should be stored in clean, dry, ventilated environment.
3. Engine oil has to be changed after using 10 hours for new machine or each 50 hours use.
4. After 100 hours use, inspect and remove the cumulative carbon on the engine spark plugs, than check and adjust spark plug gap to
0. 6mm.
5. The regular maintenance of machines is necessary.
