8. Continue breaking around the original hole, in 2 inch sized bites.
9. Release Trigger to stop the tool.
Note: If you encounter a breakdown or the tool stops for any reason, release the trigger and power down
the hydraulic power source.
COLD WEATHER OPERATION
If the breaker is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the
normally recommended fluid, fluid temperature should be at or above 50 °F/10 °C (400 ssu/82 centistokes) before
use.
Damage to the hydraulic system or breaker can result from use with fluid that is too viscous or thick.
UNDERWATER MODEL PREVENTATIVE MAINTENANCE - FIG. 4
After each use, the movable portions of the tool that were exposed to water should be flushed with a water displacing
oil such as WD40™. Remove any remaining water and debris as follows:
1. Spray oil into the On/Off valve trigger slot area.
2. Turn the tool upside down (without the tool bit) and spray oil through the drive hex and side holes in the breaker
foot assembly to displace any remaining water in the lower piston cavity.
3. Dip or spray the entire tool.
4. Cycle the tool hydraulically several times before storing away.
