Additional safety instructions

•  Also study all instructions relating to safety and operation in the corresponding operating instructions of the system products (vacuum base plate, drill stand, diamond core drilling machine).
•  Keep the air vents of the pump free from dirt and dust. Ensure adequate free space at the air discharge to prevent overheating.
•  Stand the pump on a dry, horizontal surface for operation and secure the vacuum pump so that it cannot slip out of position.
•  In the event of failure of the electric supply or malfunction of the product, the vacuum is maintained for a short time. Stop working immediately and check the pressure gages on the vacuum pump and vacuum base plate. Secure the drilling system so that nothing can fall.
•  Do not tamper with or modify the product in any way.
•  Use only Hilti Hilti spare parts.
•  Always empty the water separator before transporting the vacuum pump.
• Ensure that the working area is well-lit.
•  At regular intervals, check the vacuum hose for leaks and damage and replace faulty hoses without delay.
•  Avoid kinks in the vacuum hose.
•  Keep the supply cord, extension cord, water hose and vacuum hose away from rotating parts of the machine.
•  This product is not intended for use by persons (including children) with physical, sensory or mental disabilities or persons lacking the appropriate experience and/or knowledge. These persons must receive instruction in safe handling of the appliance and must be supervised throughout their use of the appliance by a responsible person.

Technical data

Before use

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.

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

Operation

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

Observing pressure gage

•  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 been repaired or replaced by Hilti Service?
•  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 11
•  If the safety valve trips, the vacuum pump stops creating a 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 11

Switching off the 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.
5.  If applicable, set the drill stand down safely.
6.  Remove the vacuum hose from the vacuum base plate.
7.  Unplug the supply cord from the power outlet.

Care and maintenance

Electric shock hazard! Attempting care and maintenance with the supply cord connected to a power outlet can lead to severe injury and burns.

•  Carefully remove stubborn dirt from the tool.
•  Clean the air vents carefully with a dry brush.
•  Use only a slightly damp cloth to clean the casing. Do not use cleaning agents containing silicone as they can attack the plastic parts.
• Repairs to the electrical section of the tool or appliance may be carried out only by trained electrical specialists.
•  Check all visible parts and controls for signs of damage at regular intervals and make sure that they all function correctly.
•  Do not operate the product if signs of damage are found or if parts malfunction. Has it been repaired immediately by Hilti Service?
•  After cleaning and maintenance, fit all guards or protective devices and check that they function correctly.
• To help ensure safe and reliable operation, use only genuine Hilti spare parts and consumables. Spare parts, consumables, and accessories approved by Hilti for use with the product can be found at your local Hilti Store or online at: www.hilti.group.

Emptying water separator

If the water separator fills up while drilling is in progress or if the safety valve trips, interrupts the drilling operation, switch the drilling system off and secure the drilling system so that nothing can fall.

1.  Interrupt the drilling operation and switch the drilling system off.
2.  Secure the drilling system so that nothing can fall.
3.  Switch the vacuum pump off.
4.  If applicable, vent the vacuum.
5.  Turn the water separator container in the OPEN direction and pull it down and off (bayonet connection).
6.  Empty the container.
7.  Check the ball float.
8.  Carefully ease the ball float free if it is stuck.
9.  The ball is loose at the bottom of the cage and the intake aperture is clear.
10.  Clean the edge of the water separator.
11.  Position the water separator on the bayonet connector of the container and turn it in the CLOSE direction.

Troubleshooting

Vacuum pump is running but not enough vacuum is

achieved at the vacuum plate (pressure gage of the vacuum base plate in red zone).

| The filter is clogged.| ▶| Contact Hilti Service.
Dirt in the hoses, fittings, pump or vacuum baseplate seals (water separator, connectors, etc.).| ▶| Clean out the hoses, fittings and seals or replace them if necessary.
Operation at high altitude.| ▶| Use an anchor base plate to secure the drilling system.
Vacuum pump is running but not enough vacuum is cre- ated (pressure gage of the vacuum pump in red zone).| Water separator is full.| ▶| Empty the water separator.

→ page 11

Ball float has become stuck.| ▶| Check the ball float. → page 11
Water separator is leaking, dam- aged or not installed.| ▶| Fit the water separator. Replace it if damaged.
Hose is damaged or squashed.| ▶| Contact Hilti Service.
Vacuum pump is faulty.| ▶| Contact Hilti Service.
Vacuum pump does not start.| Power failure.| ▶

▶

| Check the fuses and cables. Check the position of the switch. Check that the electric supply voltage complies with the details given on the rating plate.
Supply cord not connected.| ▶| Connect the supply cord.
Vacuum pump is faulty.| ▶| Contact Hilti Service.
Vacuum pump switches itself off.| Vacuum pump overheated.| ▶

▶

▶

| Let the product cool down. The vacuum pump starts up again automatically after it has cooled down sufficiently.

Clean the air vents.

Check the operating voltage.

The water separator container cannot be removed.| System is still under vacuum.| ▶| Vent the vacuum (e.g. by means of the vacuum release valve of the vacuum base plate).
