Power drill: operation and use

The perforator combines the principle of the jackhammer, and that of the percussion drill. It allows both the striking with specific tools type "chisel" (flat or tip) and drilling in hard surfaces (concrete, brick, etc.) with drill bits for masonry. Unlike a conventional drill, the drill does not have a jaw mandrel for clamping and locking cylindrical shanks, but a keyed chuck that can lock the chisels and specific bits with fluted shanks (SDS type). that snap into it in one click.

Necessary material

  • SDS Plus Concrete Drill
  • Peak chisel SDS Plus
  • Flat chisel 20 mm
  • Flat chisel 40 mm

Security equipment

Put on a protective mask

Put on a protective mask

1. The perforator, in its mode of operation "strikes", can project concrete or masonry pieces violently. Put on an integral protection mask.

Wear a noise-canceling helmet

2. The perforator, like any striking tool, is very noisy. Wear an earmuff.

Preparation of the perforator

Engage the battery on the perforator

1. The device shown here operates autonomously on battery power. Load it to the block and engage it on the machine.

Test the battery charge

2. The charge level can be controlled by pressing a test button. For extended continuous work, always provide two batteries that are constantly being recharged.

Reversing the direction of chuck rotation

3. In "drilling" function, this drill has a reversing function. It can be used as a screwdriver for heavy duty screws. But this function is especially useful when a wick is blocked and must be brought out.

4. Test the trigger sensitivity of the machine (drive). The through button is used to adjust the direction of rotation.

5. This machine has a LED floodlight that illuminates the work area in a low light environment.

Using the perforator

Fit an SDS wick

Fit an SDS wick

1. To engage a drill bit or tool provided for a Drill (SDS), pull the chuck collar back. Engage the wick on the mandrel by retracting it. Test the freedom of movement from front to back of the drill.
