Setting The Air Pressure - Ryobi RA-NBS1832-S Operator's Manual

Check the safety yoke before use. If it is deformed or
cannot telescope, do not use the tool until it is replaced.
Operate with a deformed safety yoke could result in
serious personal injury.
Never wedge or hold back the safety yoke mechanism
during operation of the tool. Doing so could result in
possible serious injury.
Avoid triggering the fastener driving tool if the magazine
is empty.
Any defective or improperly functioning fastener driving tool
must immediately be disconnected from the compressed
air supply and passed to a specialist for inspection.
In the event of longer breaks in work or at the end of the
working shift, disconnect the tool from the compressed air
supply and it is recommended to empty the magazine.
The compressed air connectors of the fastener driving tool
and the hoses should be protected against contamination,
the ingress of coarse dust chips, sand, etc, will result in
leaks and damage to the fastener driving tool and the
couplings.
Single sequential actuation mode
The tool employs single sequential actuation mode.
1. Connect the tool to the air supply.
2. Grip the tool firmly to maintain control. Position the
safety yoke of the tool onto the work surface.
3. Push the tool against the work surface to depress the
workpiece contact.
4. Squeeze the trigger to drive a fastener.
5. Allow the tool to recoil away from the work surface as
the fastener is driven.
6. Always remove your finger from the trigger when the
fastener has been driven.
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 tool against the work. Restriction to the recoil can
result in a second fastener being driven from the tool.
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

Having checked that the fastener driving tool is functioning
correctly, apply the tool to a work piece and actuate the

trigger.
Check whether the fastener has been driven into the work
piece in accordance with the requirements.
● If the fastener is protruding, increase the air
pressure in increments of 0.5 bar, checking the
result after each new adjustment;
● If the fastener is driven into an excessive depth,
reduce the air pressure in increments of 0.5 bar
until the result is satisfactory.
● It is preferred to adjust the depth adjustment knob
to reach the good fastening effect.
Work with the lowest possible air pressure. This will give
you three significant advantages;
1. Energy will be saved,
2. Less noise will be produced,
3. A reduction in fastener driving tool wear will be
achieved.
The amount of air pressure required will depend on the
size of the fastener and the workpiece material.
Begin testing the depth of drive by driving a test fastener
into the same type of workpiece material used for the
actual job.
Drive a test fastener 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 9.
The driving depth of the fastener 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 fastener. 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 adjustment knob left or right to change
the driving depth.
3. Reconnect the tool to the air supply.
4. Drive a test fastener after each adjustment until the
desired depth is set.

See figure 10.
1. Disconnect the tool from the air supply.
Disconnect the tool from the air supply before
performing maintenance. Failure to do so could result
in serious personal injury.
