Cordless rotary hammer

TE DRS OSHA

▶ Hilti developed TE DRS dust collection system with a filter cleaning mechanism and 99% filter

efficiency, compliant with OSHA 1926.1153, Table 1. The TE DRS-4-A dust box is compatible with the

TE DRS-4-A and TE DRS-4-A (T1) only. The TE DRS-6-A d us t box is compatible with the TE DRS-6-A

and TE DRS-6-A (T1) only.

Set-up

1. Empty the TE DRS dust box, and clean and inspect the filter.

2. A ttach the TE DRS module to the rotary hammer.

3. S tart TE DRS vacuum by pressing tool’s contro l switch.

4. V erify p rop er operatio n of the TE DRS vacuum, including suction at the extraction head.

◁ Check for damage or leaks in the dust box, hose, and extraction head.

◁ Make sure the hose extends/retracts freely.

Drilling

1. S tart drilling, and allow the TE DRS to reach full speed before beginning to drill.

◁ Hold the rotary hammer perpendicular to the work surface and keep the extraction head in contact

with the work s

urface.

2. To maximize dust collection, after the hole is drilled, slowly withdraw bit from the hole, and keep the

rotary hammer running until the bit is fully withdrawn.

Cleaning and maintenance

▶ Empty the dust box after every5in

of hole drilling (e.g. after 8-10 holes 5/8 inx2in (16 mm x

50 mm)).

▶ After every 3 in

of hole drilling (e.g. after5holes ⌀ ½ in depth3in (⌀12 mm x 76 mm)) or if suction

performance decreases push the button of the cleaning mechanism 5 times in each direction.

▶ To minimize dust emission, either useavacuum to clean the dust box or place the dust box in a

plastic bag keeping it closed as much as possible.

▶ Replace the filter if the dust debris cannot be removed, or if there are

any tears or leaks in the filter.

▶ If more-than-usual d

ust is emitted during drilling, inspect the TE DRS system , and clean/inspect the

dust box and filter.
