Installing or removing the bit
Clean the bit shank and apply bit grease before installing the
bit.
Insert the bit into the tool. Turn the bit and push it in until it
engages.
If the bit cannot be pushed in, remove the bit. Pull the chuck
cover down a couple of times. Then insert the bit again. Turn
the bit and push it in until it engages.
After installing, always make sure that the bit is securely held
in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the way and
pull the bit out.
Bit angle (when chipping, scaling or demolishing)
The bit can be secured at 12 different angles. To change the
bit angle, depress the lock button and rotate the change lever
so that the pointer points to the O symbol. Turn the bit to
the desired angle.
