Before use

Setting up vacuum pump

WARNING
A damaged supply cord presents a hazard! Do not touch the supply cord or extension cord if damaged while working. Disconnect the supply cord plug from the power outlet.

• If the power tool’s supply cord is damaged it must be replaced with a specially-prepared and approved supply cord available from Hilti Customer Service.

1. Find a suitable location with the following characteristics:
   • Supporting surface is smooth and dry.
   • Cooling air inlet and cooling air outlet have at least 20 cm clearance from walls and other obstructions.
2. Secure the vacuum pump against slippage.
3. Check the water level in the water separator and empty it if necessary.
4. Connect the vacuum connector on the vacuum base plate to the vacuum pump.

Operation

 Switching on vacuum pump

1. Plug the supply cord into the power outlet.
2. Press the on / off switch.
   •  The vacuum pump starts.

Checking vacuum

Check operation of the vacuum pump and check the vacuum after maintenance work and before every use.

1. Plug the supply cord into the power outlet.
2.  Switch on the vacuum pump. → page 4
   • Within a short time, the needle of the pressure gauge is in the green part of the scale.

Observing pressure gage

The pressure gage shows the current partial vacuum created by the vacuum pump.

• Pressure gage in green zone → partial vacuum is adequate
•  Pressure gage in red zone → partial vacuum is too low
• Observe the pressure gages on the vacuum pump and vacuum base plate while drilling is in progress.
• The pressure gage must remain constantly in the green zone throughout the drilling operation.
• If the pressure gage drops to the red zone, interrupt the drilling operation and switch the drilling system off. Secure the drilling system so that nothing can fall!
• At regular intervals, check the vacuum hoses for leaks, kinks or other damage.
• Have faulty parts repaired or replaced by Hilti Service.

Observing fill level of water separator

The water separator has a safety valve that mechanically shuts off the intake aperture if the fill level is too high. This prevents the vacuum pump from intaking water and suffering damage.

• Observe the fill level of the water separator while drilling is in progress. If possible, empty the water separator before the safety valve trips.
• Empty the water separator. → page 5
• If the safety valve trips, the vacuum pump stops creating vacuum and the partial vacuum created until then will slowly drop.
•  Interrupt the drilling operation and switch the drilling system off. Secure the drilling system so that nothing can fall.
• Empty the water separator. → page 5

Switching off vacuum pump

1. Stop drilling and switch the drilling system off.
2. Remove the drilling system.
3. Switch the vacuum pump off by pressing the on/off switch.
4. Operate the vacuum release valve on the vacuum base plate.
   •  If applicable, set the drill stand down safely.
5. Remove the vacuum hose from the vacuum base plate.
6.  Unplug the supply cord from the power outlet.
