before changing accessories, storing, carrying or when not using the tools.
15. Mounting the drill bit
○ To prevent accidents, make sure to turn the switch off and pull out the battery.

parts designated by our company.
○ Clean the shank portion of the drill bit.

change lever while the motor is running may cause the tip tool to unexpectedly
rotate and result in an accident.
17. Rotation + hammering

When the drill bit touches construction iron bar, the bit will stop immediately and
the rotary hammer will react to revolve. Therefore fi rmly tighten the side handle,
hold the body handle and side handles.
18. Rotation only
○ To drill wood or metal material using the drill chuck and chuck adapter (optional
accessories).
DH18DBQL: Using drill chuck holder
(standard accessories)
○ Application of force more than necessary will not only expedite the work, but will
deteriorate the tip edge of the drill bit and reduce the service life of the rotary
hammer in addition.
○ Drill bits may snap off while withdrawing the rotary hammer from the drilled hole.
For withdrawing, it is important to use a pushing motion.
○ Do not attempt to drill anchor holes or holes in concrete with the machine set in the
rotation only function.
○ Do not attempt to use the rotary hammer in the rotation and striking mode with the
drill chuck and chuck adapter attached. This would seriously shorten the service
life of every component of the machine.
