SAVE THESE SAFETY INSTRUCTIONS.
WARNING: To avoid mistakes and serious injury, do not use your tool until the following steps have
been read and understood
1. READ and become familiar with this entire instruction manual, no matter how boring it may be. LEARN the
tool’s applications, limitations, and possible hazards.
2. ALWAYS keep your work area clean, uncluttered, and well lit. DO NOT work on floor surfaces that are
slippery with sawdust or wax.
3. DO NOT USE THE TOOL in the presence of flammable dust, gases or fumes. The tool may produce a
spark that could ignite gases causing a fire. Driving a nail into another nail may also cause a spark.
4. KEEP BYSTANDERS AT A SAFE DISTANCE from the work area, especially when the tool is operating.
NEVER allow children or pets near the tool.
5. MAKE THE WORKSHOP CHILDPROOF. Use padlocks and master switches and ALWAYS remove
starter keys. Keep bystanders, children and visitors away while operating the power tool. Distractions can cause
you to lose control. When tool is not in use, it should be locked away in a safe place.
6. DRESS FOR SAFETY. Do not wear loose clothing, gloves, neckties, or jewelry (rings, watches, etc.) when
operating the tool. Inappropriate clothing and items can get caught in moving parts and draw you in. ALWAYS
wear non-slip footwear and tie back long hair.
7. USE PERSONAL PROTECTIVE EQUIPMENT.
• Everyone in the work area MUST wear safety glasses with side shields that conform to ANSI Z87.1
requirements (approved glasses have “Z87” printed or stamped on them). It is the employer’s responsibility to
enforce the use of eye protection equipment by both the tool operator and others in the work area.
• Wear a face mask or dust mask to fight the debris produced by operation.
• Wear ear protection such as plugs or muffs to fight hearing loss.
• Wear work gloves to protect your hands.
8. KEEP ALERT. Watch what you are doing. Use common sense. Do not operate any tool when you are tired or
under the influence of drugs, alcohol or medication that may affect your ability to properly use the tool.
9. DO NOT OVERREACH. Keep proper footing and balance at all times. Wear oil-resistant rubber-soled
footwear. Keep the floor clear of oil, scrap, and other debris.
10. DO NOT FORCE THE TOOL to do a job for which it was not designed.
11. INSPECT TOOL BEFORE USE. Do not operate if any portion of the tool, trigger, or safety bracket is dam-
aged, inoperable, disconnected, or altered. Leaking air, damaged parts, or missing parts should be repaired or
replaced before use
12. WHEN CONNECTING TO THE AIR SUPPLY, the tool is at risk of possibly firing fasteners. Be aware of
this and do not aim the gun at anything you do not want to shoot a nail into.

SAFETY RULES
13. USE ONLY clean dry and regulated air. Condensation from an air compressor can rust and damage the
internal workings of the tool.
14. DO NOT USE BOTTLED GASES to power this tool. Bottled compressed gases including but not limited to
oxygen, carbon dioxide, nitrogen, hydrogen, propane, acetylene or air are not for use with pneumatic tools. Never
use combustible gases or any other reactive gas as a power source for this tool. DANGER OF EXPLOSION
AND/OR SERIOUS PERSONAL INJURY MAY RESULT.
15. REGULATE AIR PRESSURE. Use air pressure that is compatible with the ratings on the nameplate of the
tool (70 to 120 PSI).
16. USE PROPER EXTENSION CORDS. When using an air compressor outdoors, use only rounded jackets
extensions cords. These are intended for outside use. See manufacturer’s manual for the AWG required for the
compressor’s amperage draw.
17. ALL COMPONENTS including hoses, connectors, filters, regulators, etc. must have working pressure rating
of at least 180 PSI (150% of the maximum operating pressure).
18. PAY ATTENTION TO AIR HOSE AND THEIR CONNECTIONS. Don’t trip over the hoses. Also,
make sure the connections are nice and tight. Use appropriate hose tape to prevent leaking.
19. MAKE SURE HOSE is free of obstructions or snags. Entangled or snarled hoses can cause a loss of balance.
20. USE COUPLINGS that relieve all pressure from the tool when it is disconnected from the power supply. Use
hose connectors that shut off the air supply from the compressor when the tool is disconnected.
21. LOAD FASTENERS AFTER connecting the tool to the air supply. Otherwise, fasteners are at risk of being
fired during connection. The tool’s driving mechanism may cycle when it is connected to the air supply.
22. DO NOT DEPRESS THE SAFETY BRACKET OR THE TRIGGER WHEN LOADING.
23. ALWAYS ASSUME that the tool contains fasteners. Do not point the tool at coworkers or yourself at any
time, nails may be fired unintentionally and cause serious injury.
24. DO NOT use the body of the tool or top cap as a hammer. Discharged fasteners may follow unexpected
paths and cause bodily injury.
25. KEEP HANDS AND BODY PARTS CLEAR of immediate work area. Hold workpiece with clamps when
necessary to keep body parts out of potential harm. Be sure the workpiece is properly secured before pressing the
nailer against the material. The safety bracket may cause the work material to shift unexpectedly.
26. GRIP THE TOOL FIRMLY with both hands to maintain control while still allowing it to recoil away from
the work surface as the fastener is driven.
27. KEEP FACE AND BODY PARTS away from the back of the tool cap when working in restricted areas.
Sudden recoil can result in impact to the body, especially when nailing into hard or dense material.
5

28. DO NOT DISCHARGE fasteners into open air, concrete, stone, extremely hard woods, knots or any
material too hard for the fastener to penetrate.
29. DO NOT DRIVE FASTENERS near the edge of your work material. The workpiece may split, causing the
fastener to ricochet, injuring you or a bystander. Be aware that the nail may follow the grain of the wood, causing
it to protrude unexpectedly from the side of the work material. Drive the nail perpendicular to the grain to reduce
risk of injury.
30. DO NOT DRIVE NAILS onto the heads of other fasteners. Do not use the tool at too steep of an angle.
Personal injury from strong recoil, jammed fasteners, or ricochetted nails may result.
31. BE AWARE OF MATERIAL THICKNESS when using the nailer. A protruding nail may cause injury.
32. KNOW that when the tool is being utilized at pressures on the high end of its operating range, nails can be
driven completely through thin or very soft work material. Make sure the pressure in the compressor is set so that
nails are set into the material and not pushed completely through.
33. REMOVE FINGER FROM TRIGGER when not driving fasteners. Never carry the tool with your finger on
the trigger.
34. IF THE FASTENERS ARE JAMMED, disconnect the tool from the air supply first before removing the
jammed fasteners.
35. DISCONNECT tool from air supply when not in use. Remove fasteners from magazine before leaving the
area or passing the tool to another operator. Do not climb ladders, stairs, scaffoldings, etc. without disconnecting
the tool. Do not carry a connected tool to another work area. Do not make adjustments, remove magazine,
perform maintenance or clear jammed fasteners while connected to the air supply. If the safety bracket is adjusted
when the tool is connected to the air supply with loaded nails, accidental discharge may occur.
36. DO NOT REMOVE, tamper with, or otherwise cause the tool, trigger or safety bracket to become
inoperable. Do not tape or tie the trigger or safety bracket in the ON position. Do not remove springs from the
safety bracket. Make daily inspections for free movement of the trigger and safety bracket. Do not alter or modify
the tool in any way.
37. MAINTAIN TOOLS PROPERLY. ALWAYS keep tools clean and in good working order. Follow
instructions for lubricating, changing accessories and storage.
NOTE: The warnings, cautions, and instructions explained in this manual cannot cover all possible
conditions and situations that may occur. It must be understood by the operator that common sense
and caution are factors which cannot be built into this product, but must be supplied by the operator.

PREPARATION AND ADJUSTMENTS
LUBRICATING THE TOOL (Fig. 1)
This tool requires lubrication before each use (especially the first use). Proper lubrication is the owner’s responsibil-
ity. Failure to lubricate the tool properly will dramatically shorten the life of the tool and void the warranty.
Fig. 1
Oil
NOTE: An automatic in-line oiler is a convenient way to provide oil to
the tool. If an in-line oiler is installed, manual lubrication through the
air inlet is not required.
1. Make sure the tool is disconnected from the air supply before adding
lubricant.
2. Turn the tool so the air inlet is facing up. Place 4 to 5 drops of air tool
lubrication oil into the air inlet (Fig. 1). NOTE: Excessive lubrication
may damage the work surface. Wipe off any excess oil from the inlet.
CONNECTING THE TOOL TO AN AIR SUPPLY (Fig. 2)
Connect your tool to a properly installed compressed air supply. The working pressure of the air compressor must
be regulated by a regulator to fit the operating pressure of your nailer (70-120 PSI). All components including hoses,
connectors, filters, regulators, etc. must have a working pressure rating of at least 180 PSI. Refer to the diagram
below (Fig. 2) for the recommended accessories and connection order.
WARNING: Connect the air supply before loading fasteners. Make sure the nailer magazine is empty
when connecting to the air supply. Never aim the tip of the nailer towards yourself or others.
WARNING: Use only clean dry and regulated air. Never use oxygen combustible gases, bottled gases or
high pressure compressed gas to power this tool. Danger of explosion and/or serious personal injury may
result. Do not operate when the air pressure is outside of the operating pressure range.
1. Turn on the compressor on and set the regulator (Fig. 2 - Regulator) to the proper pressure within 70 to 120 PSI.
The pressure can be adjusted later depending on firing depth, the length of nails and the hardness of the workpiece.
2. Be sure the air hose is depressurized when installing or removing adapters to the air line. Connect the compressed
air hose to the inlet of your air compressor. Connect the other end of the air hose to the air inlet of the nailer. The
connections must click into place audibly. Use appropriate hose tape to prevent leaking.
3. To disconnect the tool from the air hose, pull back the ring on the quick connector to release the connection.
Repeat for disconnecting the air compressor from the air hose.

ADJUSTING THE AIR OUTLET (Fig. 5)
Air will be released from the air outlet during operation. Rotate the ad-
justable air outlet cap (Fig. 5) on the top of the nailer to direct the re-
leased air to your preferred direction, away from yourself and others.
NON-MARRING TIP (Fig. 6)
The rubber non-marring tip (Fig. 6 - 1) is attached to the safety bracket
to reduce marring and damage to your workpiece during operation.
The non-marring tip can be removed from the safety bracket to increase
the driving depth and allow better grip on the surface using the no-slip
teeth (Fig. 6 - 2). However this may leave dents on your workpiece.
WARNING: Disconnect tool from air supply before remov-
ing or installing the non-marring tips.
To detach the non-marring tip, flip open the locking clip (Fig. 6 - 3) and
slide the non-mar tip off the safety bracket. To attach the non-marring
tip, slide it onto the safety bracket and secure it with the locking clip (Fig.
6 - 3).

PREPARATION AND ADJUSTMENTS
LOADING THE FASTENERS (Fig. 3 & 4)
WARNING: Always load the fasteners after connect-
ing the tool to its air supply. Never aim the tip of the
nailer at a person or animal in case of misfire.
1. Slide the feeder shoe (Fig 3 - 2) all the way to the back of the
magazine until it click into place.
2. Place the fasteners into the magazine slot with the tip pointing
downwards. Slide the fasteners forward against the front of the
magazine.
Your nailer accepts 21-degree round head framing nails with di-
ameter ranging from 0.113" - 0.131" (2.87 - 3.33 mm) and length
ranging from 2" - 3-9/16" (50 - 90 mm). A maximum of 60 fasten-
ers may be loaded.
3. Pull the feeder shoe backwards, and press the magazine lock.
Release the feed shoe, allowing it to spring forward against the
nails to secure them in position. Check that the nails have been
loaded correctly and securely.

TO CHANGE THE TRIGGER (Fig. 7)
WARNING: Disconnect the nailer from the air supply and
remove fasteners from magazine before making adjustments
to the tool.
1. Remove the o-ring on the side of the trigger pin. It may be easiest to
use tweezers, a paperclip, or other appropriate tool. Be careful to not
damage the O-ring.
2. Remove the trigger pin, the trigger and the trigger spring.
3. Swap the trigger switch out for the alternative trigger.
4. Replace the trigger spring, the trigger, the trigger pin and the o-ring.
TYPES OF TRIGGERS
Two different triggers are included with your nailer. Fully understand the characteristics and activation mode of each
trigger. Choose the suitable trigger that fits the task at hand.
Sequential Trigger (Black Trigger):
Your nailer is installed with the sequential trigger. With this trigger installed, the safety bracket needs to be activated
before pulling the trigger in order to drive a fastener. This trigger prevents the nailer from being able to bump fire,
which means you cannot hold down the trigger and press down on the safety bracket to fire multiple nails in a row.
This would be the preferred method for safer operation and more detailed and specific nailing jobs.
Contact Trigger (Red Trigger):
The contact trigger is provided as an accessory. Using this trigger, you can activate the safety bracket and trigger in
any sequence to drive a fastener. This trigger gives users the opportunity to both bump fire (where the trigger re-
mains engaged and the bumping of the safety bracket shoots nail after nail) and also sequential fire (where the safety
bracket remains engaged and the repetitive pulling of the trigger shoots nail after nail). Only one of the two safety
mechanisms (the trigger or the safety bracket) needs to be disengaged between firing multiple nails. This is best for
larger jobs where speed is more important than precision. However, there is also is a higher chance of misfiring
when the contact trigger is installed.
WARNING: There is a higher chance of misfiring when the contact trigger is installed. Never put your
finger on the trigger unless you are prepared for operation. Unintended nails can be discharged when the
trigger is engaged and the safety bracket is pressed by accident.
PREPARATION AND ADJUSTMENTS
WARNING: Before each use, check the nailer, compressed air connections and air lines. If any parts
are missing or damaged, do not operate this tool until the parts are repaired and replaced. Failure to do
so could possibly result in a serious personal injury.
