OPERATION
SELECTING THE FUNCTION
The rotary hammer has three methods of removing material. The position of the
front and rear selector switch together sets the rotary hammer’s function.
Drilling
The bit rotates to bore through the material. Set the front
switch (D) to the hammer and drill bit icon. Set the rear
selector (H) switch to the drill icon.
Chisel
The bit moves forward and backward rapidly to break
material. Set the front switch (D) to the hammer icon. Set
the rear selector (H) switch to the hammer and drill bit icon.
Hammer Drilling
The bit combines the motions of chiseling and drilling to
break and remove material rapidly. Set both the front and
rear switch to the hammer and drill bit icon.
