Technical line drawing of a mechanical device with wheels and a base mount (no text or symbols)

• Place the bottom plate in the desired position.
• Switch on the vacuum pump. A minimum pressure of 635 mm Hg (25 inch Hg) must be reached so that the base plate seals tightly against the surface.

Fixing with expander or anchor

IMPORTANT! When drilling roofs, only expander or anchor suitable for surfaces exposed to tensile forces should be used.

Use only expander or anchor which is approved for current application.

335 mm (13,2")

• Drill a hole for the expander/anchor at a distance of 335 mm (13.2") from the centre of the hole.
• Bolt down the base plate.
  Check carefully that the expander is secured correctly.
• The bottom plate can be adjusted to the surface by using the leveling adjustment screws. Use the feed lever.

Fixing with threaded rod, washer and lock nut

If the mounting surface is inadequate for drilling in roofs or walls, the base plate can be fixed using a threaded rod, which is mounted on the backside with a washer and lock nut.

Check the ground fault circuit interrupter. See instructions under the heading Checking, maintaining and servicing the machine's safety equipment.

Drilling in the ceiling

WARNING! The vacuum plate must never be used for ceiling drilling.

Use a water collector to avoid water penetrating into the machine. The machine must be covered with plastic or the like in order to prevent water penetrating into the machine, but do not cover the air intakes and air outlets.

WARNING! Check that no one on the floor below can be injured by falling concrete cores.

Starting

• Turn on the water cooling.
- Press in the switch fully.
- Allow the machine to come up to full speed before contacting workpiece.
- Start to feed the drill bit with the help of the feed handle.

Use very light pressure for the first few millimeters to keep the bit from wandering. Then proceed normally. It's not necessary to use excessive force. This will only slow drilling and overload the motor.

Use especially light pressure when you encounter steel reinforcing rods. High pressure against reinforcing rods will trip the circuit breaker. If the circuit breaker trips, remove the bt from contact with the workpiece before resetting.

Stopping

WARNING! The drill bit continues to rotate for a while after the motor has been switched off. Do not stop the drill bit with your hands. Personal injuries can occur.

Shut down the machine by pressing the power switch.
