Safety instructions

WARNING! Read all instructions! Observe all applic-able safety rules and the operating instructions for the Hilti rotary hammer used. Failure to observe the instructions could lead to serious injury.

SAVE THESE INSTRUC-TIONS. Use the side handle of the Hilti rotary hammer for all applications, including when the TE DRS-4‑A is fitted.

Dusts
This dust removal module collects a significant percent-age of the dust produced, but not all of it.

WARNING : Some dust created by grinding, sand-ing, cutting and drilling contains chemicals known to cause cancer, birth defects, infertility or other repro-ductive harm; or serious and permanent respiratory

or other injury. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks, concrete and other masonry products and natural stone, arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce expos-ure to these chemicals, the operator and bystanders should work in a well-ventilated area, work with ap-proved safety equipment, such as respiratory protec-tion appropriate for the type of dust generated, and designed to filter out microscopic particles and direct dust away from the face and body. Avoid prolonged contact with dust. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, nose, eyes, or to remain on your skin may promote absorption of harmful chemicals.

Before making adjustments to the power tool, check that the tool is switched off, the battery has been removed and the safety lock is activated (forward/reverse selector switch in the middle position).

Fitting the dust removal module

NOTE
Dust may be released when the filter container is full. Accordingly, the container should be emptied regularly. Wear respiratory protection when doing this.

NOTE
The suction fan incorporated in the dust removal module is driven by its own motor. This motor is powered by the power tool’s battery.

NOTE
Before fitting the dust removal module, check to ensure that the mounting points and the power tool itself, especially the electrical interface on the power tool, are free from dust and other foreign matter. After fitting the dust removal module, check to ensure that it is securely attached.

NOTE
If the power tool is cordless, set the forward / reverse switch to the middle position.

1. Remove the drill bit from the power tool.
2. Remove the depth gauge from the side handle.
3. Position the dust removal module on the guides and push it onto the power tool until it engages.

Removing the module

1. Remove the drill bit from the power tool.
2. Press the DRS release buttons and hold them in this position.
3. Pull the dust removal module downwards away from the power tool.

Operation

Preparing for use

CAUTION
Before making adjustments to the power tool, check that the tool is switched off, the battery has been removed and the safety lock is activated (forward/reverse selector switch in the middle position

Length adjustment (stroke

CAUTION
When the stroke limit button is pressed, the telescopic section is released and may then jump out a distance of up to 100 mm (3¹⁵⁄₁₆″).

NOTE
The stroke is normally set for use with drill bits with a total length of 170 mm (6″). The stroke must be adjusted if shorter drill bits are used.

1. To adjust the stroke length, press the stroke limit button and hold it in this position.
2. Press the power tool (with drill bit fitted) against a wall until the tip of the drill bit touches the wall.
3. Release the stroke limit button.

Setting drilling depth (depth gauge)

NOTE
