Preparing The Tool - DeWalt DCN45RNN Original Instructions Manual

English
Bump Action
Bump action is intended for rapid nailing on flat, stationary
surfaces and typically most effective for applications that require
driving shorter nails.
To Operate the Tool Using the Bump Actuation Method
1. Depress the trigger.
2. Push the contact trip against the work surface. As long as
the trigger is depressed, the tool will fire a nail every time
the contact trip is depressed. This allows the user to drive
multiple nails in sequence.

WARNING: Do not keep trigger depressed when tool is not
in use. Keep the trigger lock‑off in the locked position when
the tool is not in use.

WARNING: When the tool's motor is running, the next
actuation, pulling the trigger or depressing the contact
trip, will cause a nail to fire.

Preparing the Tool

NOTICE: NEVER spray or in any other way apply
lubricants or cleaning solvents inside the tool. This can

of this manual.
2. Wear eye and ear protection.
3. Remove battery from tool.
4. Ensure magazine is empty of all fastners.
5. Check for smooth and proper operation of contact trip and
pusher assemblies. Do not use tool if either assembly is not
functioning properly. nEVER use a tool that has the contact
trip restrained in the actuated position.
6. Keep tool pointed away from yourself and others.
7. Insert fully charged battery pack.
Using the Trigger Lock‑Off (Fig. D)
Each D WALT nailer is equipped with a trigger lock‑off
E
when pushed to the right as shown in Figure D, prevents the
tool from firing a nail by locking the trigger and bypassing
power to the motor.
When the trigger lock‑off is pressed to the left, the tool will be
fully operational. The trigger lock‑off should always be locked
off whenever any adjustments are made or when tool is not in
immediate use.
