MAINTENANCE COLD WEATHER OPERATION
Se ee For cold weather operation, near and below freezing,
A WARNING: the moisture in the air line may freeze and prevent
tool operation. We recommend the use of air tool
lubricant or permanent antifreeze (ethylene glycol) as
a cold weather lubricant.
CAUTION:
Do not store tools in a cold weather
environment to prevent frost or ice
formation on the tool's operating valves
and mechanisms that could cause tool
failure.

Any time inspection, maintenance, and
cleaning are done:
Disconnect the tool from the air resource.
Empty the magazine completely.
ANTI-DUST
Each tool is packed with an anti-dust cap on the air
connector.
Keep the anti-dust cap cover the air connector
when the tool is not in use.
LUBRICATION
Frequent, but not excessive, lubrication is required
for best performance. Oil for the tool added through
the air line connection will lubricate the intemal parts.
Do not detergent oil or additives as these lubricants
will cause accelerated wear to the seals and
bumpers in the tool, resulting in poor tool
performance and frequent tool maintenance.
CAUTION:
Lubricate tool only with specified
lubricants.
CLEARING
Avoid using solvents when cleaning plastic parts.
Most plastics are susceptible to damage from
various types of commercial solvents and maybe
damaged by their use. Use clean cloths to remove
dirt, dust , oil, grease, etc.
A WARNING:
Do not at any time let brake fluids,
gasoline, petroleum-based products,
penetration oils, ect. come in contact
with plastic parts. Chemicals can damage,
weaken or destroy plastic which may
result in serious personal injury.

CONTACT ACTUATION MODE
Contact actuation allows very fast repetitive
fastener placement.
Disconnect the tool from the air resource.
Remove the o-ring from the trigger pin(D).
Pull the trigger pin(D) out.
Put the orange trigger on.
Push the trigger pin(D) back, using a ttle
hammer if necessary.
Put the o-ring back to fasten the trigger pin(D).
Grip the tool firmly to maintain control. Position
the nose of the tool onto the work surface.
‘Squeeze and hold the trigger, push the tool
against the work surface to depress the
workpiece contact and drive a fastener.

NOTE:
In the contact actuation mode, the tool may also be
operated by depressing the workpiece contact
against the surface and squeezing the trigger.
\\E
Trigger pin(D)
A WARNING:
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 and let the tool do the work.
Failure to heed this warning can result in
serious personal injury.

Adjustment wheel(C)
CAUTION:
Itis 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.
Never exceed 120psi.
FIRING THE TOOL
(USING THE SELECTABLE TRIGGER)
The tool is equipped with a selectable trigger set in
the single sequential actuation mode(black trigger).
The selectable trigger(orange trigger) can also be
set for contact actuation mode.
SINGLE SEQUENTIAL ACTUATION MODE
Single sequential actuation provides the most
accurate fastener placement.
1. Disconnect the tool from the air resource.
2. Remove the o-ring from the trigger pin(D).
3. Pull the trigger pin(D) out.
4, Put the black trigger on.
5. Push the trigger pin(D) back, using a little
hammer if necessary. Use Caution not to
damage the tool when reinserting the trigger pin.
6. Put the o-ring back to fasten the trigger pin(D).
7. Grip the tool firmly to maintain control. Position
the nose of the tool onto the work surface.
8. Push the tool against the work surface to
depress the workpiece contact.
9. Squeeze the trigger to drive a fastener.
