2.1 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 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

3.2 Intended use
The vacuum pump is designed to create a vacuum for securing a drill stand with a vacuum base plate and for
use in combination with vacuum holding jigs such as are used, for example, with Hilti diamond core drilling
machines (core bits up to max. 250 mm diameter).
• The vacuum pump is designed exclusively for intaking air. Intaking other gases or liquids is prohibited.
• The product must not be used in an explosive environment.

5 Before use
5.1 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.
6 Operation
6.1 Switching on vacuum pump
1. Plug the supply cord into the power outlet.
2. Press the on / off switch.
▶The vacuum pump starts.
6.2 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.
6.3 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.
6.4 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

*416186* 416186 English 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
6.5 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.
7 Care and maintenance
WARNING
Electric shock hazard! Attempting care and maintenance with the supply cord connected to a power outlet
can lead to severe injury and burns.
▶Always unplug the supply cord before carrying out care and maintenance tasks.
Care
• 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.
Maintenance
WARNING
Danger of electric shock! Improper repairs to electrical components may lead to serious injuries including
burns.
▶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.
