If you have any questions, please contact with our authorized representatives.
OX
CO 2
The operator and all persons in the general area should wear
safety glasses to guard against flying fasteners and debris,
which could cause severe eye injury. Safety glasses are per
requirements of the Regulatory Authority. Always wear hearing
protection and hard hat.
Never use oxygen, carbon dioxide or any other bottled gas as
a power source for this tool Danger of explosion and/or
serious personal injury may result.
Use only clean, dry regulated compressed air at recommended
pressure
Tools shall not be connected to a compressor which
potentially exceeds 175 psi or 12 bar.
Air hose rated for a maximum operating pressure of 150 psi
(10.3 bar) or 150% of the maximum system pressure, whichever,
is higher.
Disconnect tool from air supply and remove fasteners from
magazine before doing tool maintenance, clearing a jammed
fastener, leaving work area, moving tool to another location, or
handing the tool to another person.
120 Psi
8.3 bar
70 Psi
4.9 bar

Coupling must be used which removed all pressure from the tool
when the coupling joint is disconnected.
Never use tool that is leaking air, has damaged or missing parts.
Never point the tools at co-workers or yourself at any time .
Never carry the tool from place to place holding the trigger.
Do not alter or modify this tool from the original design or
function without approval from us or authorized representatives.
Do not remove spring from contact trip, inadvertent actuation
could occur.
Always maintain proper footing and place yourself in a firmly
balance position when using or handling the tool.
Do not drive fasteners on top of other fasteners, the fasteners
can ricochet and hurt someone.

7
Never use the body of the tool or top cap as a hammer, always
use the tool for its intended use. Do not discharge fasteners into
concrete, stone, or any material too hard for the fastener to
penetrate.
Do not drive fasteners close to the edge of the work surface.
The workpiece maysplit causing the fastener to ricochet, fly
free or hit someone.
Keep hands and body away from the discharge area of the tool.
Keep face and body away from back of the tool cap when
working in restricted areas. Sudden recoil can result in hard
impact to the body.
Never use tool in the presence of flammable dust, gases or
fumes. The tool may produce a spark that could ignite gases
causing a fire and cause the tool to explode.
Be aware of material thickness when using the nailer.

LUBRICATION AND MAINTENANCE
Use Pneumatic tool oil or a non-detergent oil. Do not use
detergent oil or additives as they will damage o-rings and rubber
parts.
Use a filter and regulator when possible
Add pneumatic oil into the air inlet twice daily. (Depending on
frequency of tool use)
Wipe tool clean daily and inspect for wear. Use solvents only if
necessary - Do Not Soak. (Solvents may damage o-rings and
other tool parts)
Drain compressor tanks and hoses daily
Clean magazine, pusher, and contact trip mechanism
periodically.
All screws, nuts and fasteners should be kept tight and
undamaged. Loose screws result in unsafe operation and parts
breakage.

Bump Fire Trigger (Black Color)
1. With your finger pulling the trigger, press the safety all the way down
on the surface of the material the fastener is being driven into.
2. This will result in a fastener being driven into the material.
3. To fire another round raise the safety completely off the material and
repeat the above steps.
Sequential Fire Trigger (Gray Color)
1. With your finger off the trigger, then hold the safety nose FULLY
against the work surface of the material the fastener is being
driven into.
2. Pull the trigger firing a fastener into the material.
3. The tool will not fire again until the trigger is release and the safety
is removed completely from the material being used.
4. To fire the next fastener repeats the above steps.

OPERATING THE TOOL
Read Safety Instruction section of this manual.
WARNING: To reduce risk of serious injury from accidental actuation when attempting to
adjust depth, ALWAYS;
Adjusting Depth:
The depth that the fastener is driven can be adjusted using the depth adjustment next to the
trigger of the tool.
To drive the nail shallower, turn the wheel(A) to right to the
extent desired.
To sink a nail deeper, turn the wheel(A) to left to the extent
desired.
Make sure that the trigger and safety move freely up and
down without binding or sticking after each adjustment.

The nail holder can be adjusted up and down per nail’s
length. To change setting, pull the post up directly and
twist to the correct step.
● For CN3383C, CN3383P, CN3390C, CN3390P tool

Post
Feed pawl Nail
Load the coil of nails.
Place the coil of nails over the post in the magazine.
Uncoil enough nails to reach the feed pawl, place the
first nail in front of the feed pawl into the driver channel
and place the second nail between the teeth of the feed
pawl. The nail heads must be in the slot in the nose.

CAUTION: Do not store the tool in a cold weather environment to prevent frost or ice
formation the tools operating valves and mechanisms that could cause tool failure.
Operation in Hot Weather
Keep tool out of direct sunlight as excessive heat can deteriorate bumpers, o-rings and other
rubber parts resulting in increased maintenance.
Operation in Cold Weather
When operating tools at temperatures near and below freezing, the moisture in the air line
may freeze and prevent tool operation. :
1. Reduce the air pressure to 80 psi (5.5 bar) or less.
2. Removed all fasteners from magazine.
3. Connect air and free-fire (blank-fire) the tool. Slow speed
operation tends to worm up the moving part.
when changing one driving location to another involves the use
of scaffoldings, stairs, ladders, or ladder alike constructions,
e.g. roof laths.
closing boxes or crates.
fitting transportation safety systems e.g. on vehicles and
wagons.
" Do not use on scaffoldings, ladders" ,
and shall not be used for specific application:
