SAFETY RULES
Safety is a combination of common sense, staying alert and knowing how your item works. 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. REGULATE AIR PRESSURE. Use air pressure that is compatible with the ratings on the nameplate of the
tool. Do not connect the tool to a compressor rated at over 175 psi even in the event of a regulator failure.
3. USE ONLY clean, dry and regulated air. Condensation from an air compressor can rust and damage the
internal workings of the tool.
4. ALWAYS keep your work area clean, uncluttered, and well lit. DO NOT work on floor surfaces that are
slippery with sawdust or wax.
5. KEEP BYSTANDERS AT A SAFE DISTANCE from the work area, especially when the tool is operating.
NEVER allow children or pets near the tool.
6. DO NOT FORCE THE TOOL to do a job for which it was not designed.
7. 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.
8. WEAR A FACE MASK OR DUST MASK to fight the debris produced by operation and ear protection to
fight hearing loss. Everyone in the work area MUST wear safety glasses with side shields. These safety glasses
must 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.
WARNING: Dust generated from certain materials can be hazardous to your health. Always
operate the tool in a well-ventilated area and provide for proper dust removal. Use dust collection
systems whenever possible.
9. ALWAYS USE an air hose that is rated at a maximum working pressure of at least 150 psi (10.3 bar) or
150% of the maximum system pressure.
10. DO NOT USE BOTTLED GASES to power this tool. Bottled compressed gases such as 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.
11. 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.
12. 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

SAFETY RULES
magazine, perform maintenance or clear jammed fasteners while connected to the air supply. If the contact
trip is adjusted when the tool is connected to the air supply with loaded nails, accidental discharge may occur.
13. 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. Do
not load fasteners or connect the air supply when the trigger or the safety is pressed down in order to prevent
unintentional firings of a fastener.
14. DO NOT REMOVE, tamper with, or otherwise cause the tool, trigger or contact trip to become
inoperable. Do not tape or tie the trigger or contact trip in the ON position. Do not remove springs from the
contact trip. Make daily inspections for free movement of the trigger and contact trip. Uncontrolled discharge
may result. Do not alter or modify the tool in any way.
15. 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.
16. MAINTAIN TOOLS PROPERLY. ALWAYS keep tools clean and in good working order. Follow
instructions for lubricating and changing accessories. Inspect tool before use. Do not operate if any portion of
the tool, trigger, or contact trip is damaged, inoperable, disconnected, or altered. Leaking air, damaged parts,
or missing parts should be repaired or replaced before use.
17. ALWAYS ASSUME that the tool contains fasteners. Do not point the tool at coworkers or yourself at any
time, even if you think it will be really funny.
18. 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.
19. DO NOT operate the tool if you are under the influence of drugs, alcohol, or medication that may affect
your ability to properly use the tool.
20. REMOVE FINGER FROM TRIGGER when not driving fasteners. Never carry the tool with your finger
on the trigger.
21. MAKE SURE HOSE is free of obstructions or snags. Entangled or snarled hoses can cause a loss of
balance.
22. DO NOT DISCHARGE fasteners into open air, concrete, stone, extremely hard woods, knots or any
material too hard for the fastener to penetrate. Do not use the body of the tool or top cap as a hammer.
Discharged fasteners may follow unexpected paths and cause bodily injury.
23. DO NOT DRIVE FASTENERS near the edge of your work material. The workpiece may split, causing
the fastener to ricochet, injuring you or a co-worker. 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.
24. 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.
25. BE AWARE of material thickness when using the nailer. A protruding nail may cause injury.

SAFETY RULES
26. 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.
27. 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 contact trip may cause the work material to shift unexpectedly.
28. 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.
29. 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.
30. GRIP THE TOOL FIRMLY to maintain control while still allowing it to recoil away from the work
surface as the fastener is driven. In bump action mode (contact actuation mode), allowing the contact trip to
recontact the work surface before the trigger is released will fire an unwanted fastener.
31. KEEP ALERT. Watch what you are doing. Use common sense. Do not operate any tool when you are
tired.
32. 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.
33. PAY ATTENTION TO AIR HOSE AND THEIR CONNECTIONS. Don’t trip over the hoses. It isn’t
fun. Also, make sure the connections are nice and tight.
34. 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.
35. DO NOT DEPRESS THE CONTACT TRIP OR THE TRIGGER WHEN LOADING.
36. IF THE FASTENERS ARE JAMMED, disconnect the tool from the air supply first before removing the
jammed fasteners.
37. This tool is equipped with safe bracket that can adjust the depth of the driver. When adjusting the depth
of the driver, first disconnect the tool from the air and rotate nut by thumb to satisfactory position.
38. DO NOT attempt to fire into hard or brittle materials such as concrete, steel or tile.
WARNING: 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. So don’t do anything stupid.

operate when the air pressure is outside of the recommended range (60 to
100 PSI). Make sure magazine is empty when connecting to air supply.
1. Determine if the tool needs oil and, if necessary, place two drops of oil
in the air inlet (Fig. 2 - 1) as outlined above in the Lubrication section.
2. Turn the compressor on and set the Regulator (Fig. 1 - Regulator) to
the proper pressure according to the size and type of fastener being used.
The air pressure range should be between 60 PSI and 100 PSI.
3. Connect the tool to the air supply (Fig. 1).
LOADING THE FASTENERS (Fig. 3)
