Information on indexing gear
Switch off the motor.
Wait for standstill.
Adjust required speed. (see fig. 4).
ATTENTION! Never change the speed drive during operation.
When changing the speed, it is recommended to turn slightly by hand the output shaft (drill
bit holder), in order to enable the gear teeth to thread.
Before underwater operation
Ensure that:
- The exhaust hose is connected and fixed at the supply hose,
- the exhaust hose is long enough to protrude above the water. In case of a short exhaust
hose (in the water) a reverse valve is used, so that water cannot get into the machine when
plunging with the machine,
- the machine is tested for leakage and for the functioning of all parts (drilling, blowing,
valves, etc.).
Notice: Keep in mind that 10 meter water depth corresponds to 1 bar.
When working in greater depths match the diameter of the supply and exhaust hose
appropriately.
After underwater operation
Clean and dry the machine with compressed air.
Spray all moving parts with multi-oil-spray.
