Clearing A Jammed Fastener; Removing Nails; Maintenance - AEG CFN90 Original Instructions Manual

NOTE: The trigger lever pivot pin is spring loaded and
held in position by locking tab to prevent movement
during operation.
5. Reconnect the tool to the air supply.
6. Grip the tool firmly to maintain control.
7. Pull and hold the trigger. Push the tool against the
work surface to depress the workpiece contact and
drive a fastener.
8. Allow the tool to recoil away from the work surface as
the fastener is driven.
NOTE: In contact actuation mode, the tool may also be
operated by depressing the workpiece contact against
the surface and squeezing the trigger.
When used in the contact actuation mode do not
carry the tool with the trigger depressed as this will
cause a fastener to discharge if the workpiece contact
accidentally bumps against an object. Failure to observe
this warning can result in serious personal injury.
During normal use the tool will recoil immediately
after driving a fastener. This is a normal function
of the tool. Do not attempt to prevent the recoil by
holding the nailer against the work. Restriction to the
recoil can result in a second fastener being driven from
the nailer. Grip the handle firmly, let the tool do the
work, and do not place second hand on top of tool or
near exhaust at any time. Failure to heed this warning
can result in serious personal injury.
SETTING THE AIR PRESSURE
The amount of air pressure required will depend on the
size of the nail and the workpiece material.
Begin testing the depth of drive by driving a test nail into
the same type of workpiece material used for the actual
job.
Drive a test nail with the air pressure set at 6.2 - 6.5 bar
(90 - 95 psi). Raise or lower the air pressure to find the
lowest setting that will perform the job with consistent
results.
It may be possible to achieve the desired depth with
air pressure adjustments alone. If finer adjustments are
needed, use the drive depth adjustment on the tool.
DRIVE DEPTH ADJUSTMENT
See figure 14.
The driving depth of the nail may be adjusted. It is
advisable to test the depth on a scrap workpiece to
determine the required depth for the application.
To determine depth of drive, first adjust the air pressure
and drive a test nail. To achieve the desired depth, use
the drive depth adjustment on the tool.
1. Disconnect the tool from the air supply.
2. Turn the depth selector left or right to change the
driving depth.
3. Reconnect the tool to the air supply.

WARNING
4. Drive a test nail after each adjustment until the
desired depth is set.
Disconnect the tool from the air supply before
removing nails or clearing a jammed fastener. Failure
to do so could result in serious personal injury.

CLEARING A JAMMED FASTENER

See figure 15.
If a nail or fastener becomes jammed in the tool,
disconnect the air hose and keep the tool pointed away
from you while clearing the jam.
1. Disconnect the tool from the air supply.
2. Remove fasteners from the tool.
3. Insert a #2 Phillips screwdriver into the driving
mechanism.
4. Tap the screwdriver gently with a hammer. The
inserted screwdriver should push the driver blade
back, freeing the nail jam.
5. Remove the bent nail, using needle-nose pliers if
necessary.
DRIVING NAILS AT AN ANGLE
See figure 16 - 17.
When driving nails at an angle, make sure that the tool is
pointed away from yourself and others.
When driving nails at an angle, make sure that the tool is
positioned correctly. Driving at an angle that is too steep
may:
● cause the nail to miss the workpiece
● cause the nail to ricochet
● cause the workpiece to splinter, causing the nail
to come back toward the operator.
Never drive a nail at an angle by tilting the tool forward.
This could lead to the fastener missing the work surface
or bouncing off the work surface, leading to serious injury.

REMOVING NAILS

1. Disconnect the tool from the air supply.
2. Open the feeder cover and magazine cover (see
loading the tool with nails).
3. Lift the nail strip from the spool and remove the
remaining coil of nails.

MAINTENANCE

When servicing use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
