10.2 TE DRS-6-A / TE DRS-6-A OSHA dust removal module
The TE DRS6A dust removal module is an accessory for the Hilti TE 6A22 rotary hammer drill. It collects
a high percentage of the dust and it attaches quickly and easily to the rotary hammer drill. The dust removal
module has a built-in extractor fan. This fan is driven by its own motor. When the rotary hammer drill is
switched on the dust removal module draws its electric power from the rotary hammer drill’s battery.
The dust removal module is not suitable for working on metal and wood.
Conditions: TE DRS-6-A OSHA
The TE DRS-6-A OSHA satisfies the requirements of OSHA 1926.1153 Table 1. It has a filter-cleaning
mechanism.
10.2.1 Fitting the dust removal module 12
Before fitting the module, check that the attachment points and the electrical interfaces on the rotary
hammer drill and dust removal module are free of dust and that the parts fit or move freely and easily.
1. Check the dust removal module for damage.
2. Check the ease of movement of the telescoping mechanism.
3. Set the forward / reverse switch on the rotary hammer drill to the middle position.
4. Remove the depth gauge from the side handle.
5. Position the dust removal module on the guides and from the front, push it on to the power tool until it
engages.
6. After fitting, check that the dust removal module is secure.
10.2.2 Drilling with the dust removal module
1. Start the dust removal module by pressing the control button on the rotary hammer drill.
2. Hold down the control button until full suction power is reached.
3. Position the suction head with the edge seated flat against the work surface.
4. Drill the hole and ease the product slowly out of the drilled hole in order to catch as much dust as
possible.
10.2.3 Emptying the dust box 13
Regular cleaning and emptying are necessary because a full dust box or a clogged filter can lead to
excessive dust formation.
Empty the dust box after drilling 8-10 holes (16 mm x 50 mm) (5/8 in x 2 in).
To minimize dust formation, carefully transfer the dust to a container with a tight-fitting lid.
1. Hold the power tool horizontal and allow it to run for a short time.
▶ This ensures that residual dust deposits in the dust removal module are drawn into the dust box.
2. Press and hold down the release button of the dust box.
3. Pull the dust box down and clear of the dust removal module.
4. Empty the dust box.
▶ Filter is clogged.
▶ Change the filter.
▶ Filter is free of dust.
5. Push the empty dust box back into the dust removal module from below until it engages.
10.2.4 Cleaning the TE-DRS-OSHA filter 14
Clean the filter after drilling 5 holes (16 mm x 50 mm) (1/2 in x 3 in).
▶ When suction power diminishes, slide the cleaning mechanism 5 times forward and back until it audibly
clicks on each slide.
10.2.5 Removing the dust removal module 15
1. Set the forward / reverse switch on the rotary hammer drill to the middle position.
