0%
We've written this article to help you to properly insert and remove chisels into the DEWALT D25981 demolition hammer. The D25981 breaker uses chisels with a 28 mm hex. shank. We recommend that you use professional accessories, like the DEWALT DT6927 and DT6929 pointed or flat chisels.
The D25981 break can use both types os chisels : chisels with a collar or chisels with a slot and no colloar.
Before you fit a new chisel always clean the chisel shank.
Take a look at the schematic diagrams in this post and follow these instructions:
To fit a chisel with collar on the shank, proceed as follows (Fig. E)
1. Pull the tool retainer 3 to the unlock position.
2. Insert the chisel shank into the tool holder 4.
3. Push the retainer 3 in line with the accessory shank to lock the accessory in position.
4. Pull on the chisel to check if it is properly locked. The hammering function requires the chisel to be able to move axially several centimetres when locked in the tool holder.
5. To remove a chisel pull back the retainer 3 and pull the chisel out of the tool holder.
To fit a chisel with notch in the shank, proceed as follows (Fig. F)
1. Pull the tool retainer 3 to the unlock position.
2. Hold the chisel in front of the tool holder with the groove 15 facing upwards.
