8 Operation
WARNING
Driving a fastener may cause flying fragments. The user
of the tool and bystanders must wear protective
glasses and a hard hat. Flying fragments present a
risk of injury to the eyes and body.
CAUTION
The fastener driving action is initiated by ignition of a
propellant charge. The operator and bystanders must
wear ear protectors. Exposure to noise can cause hear-
ing loss.
WARNING
Never make the tool ready to fire by pressing it against a
part of the body (e.g. the hand). This could cause a nail
or the piston to be driven into a part of the body. Never
press the tool against a part of the body.
WARNING
Never redrive a fastener. This may cause the fastener
to break and the tool may jam.
WARNING
Never drive fasteners into existing holes unless this
is recommended by Hilti (e.g. DX‑Kwik).
CAUTION
If the tool has overheated, allow it to cool down. Do
not exceed the recommended fastener driving rate.
8.1 Procedure if a cartridge fails to fire
If a cartridge fails to fire or misfires, always proceed as
follows:
Keep the nose of the tool pressed at right angles against
the working surface for 30 seconds.
If the cartridge still fails to fire, withdraw the tool from the
working surface, taking care to avoid pointing it toward
your body or toward bystanders.
