OPERATION
COLD WEATHER OPERATION
If the drill is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluids, fluid temperature should be at or above 50 °F/10 °C (400 SSU/ 82 centistokes) before use.
Damage to the hydraulic system or drill can result from use with fluid that is too viscous or too thick.

PREVENTATIVE MAINTENANCE
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.Turn the tool upside down (without the tool bit) and spray oil through the drive hex and side holes in the motor assembly to displace any remaining water in the lower piston cavity.
2.Spray oil into the On/Off valve trigger slot area.
3.Dip or spray the entire tool.
4.Cycle the tool hydraulically several times before storing away.
