PNEUMATIC NAILER SAFETY RULES
AIR SUPPLY SAFETY
1. USE ONLY CLEAN, DRY, AND REGULATED AIR. Condensation from an air compressor can rust and
damage the internal workings of the tool. Regularly drain water and contaminants out from the compressor.
An in-line filter is recommended to remove most of these contaminants and prolong the life of the tool the
compressor.
2. DANGER OF EXPLOSION AND/OR SERIOUS PERSONAL INJURY. 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.
3. REGULATE THE AIR PRESSURE. Use air pressure that is compatible with the operation pressure of the
tool (70 to 120 PSI). Do not let the air pressure exceed 120 PSI.
4. ALL AIR SUPPLY COMPONENTS (hoses, connectors, filters, regulators, etc.) must have a working
pressure rating of at least 180 PSI (150% of the maximum operating pressure).
5. USE PROPER EXTENSION CORDS. When using an air compressor outdoors, use only rounded-jacket
extensions cords. These are intended for outside use. See manufacturer’s manual for the AWG required for the
compressor’s amperage draw.
6. MAKE SURE THE AIR SUPPLY HOSE is free of obstructions or snags. Entangled or snarled hoses can
cause a loss of balance. Keep the hose in good condition.
7. MAKE SURE ALL CONNECTIONS are nice and tight. Use appropriate hose tape to prevent leaking. Pay
attention to air hoses and their connections to prevent tripping over them.
8. 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. It is recommended to empty the
magazine before connecting to the air supply.
9. MAKE SURE HOSE is free of obstructions or snags.
10. 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.
FASTENERS SAFETY
1. 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.
2. DO NOT ENGAGE the safety bracket or the trigger when loading nails.
3. ALWAYS ASSUME THAT THE TOOL CONTAINS FASTENERS. Do not point the tool at others or
yourself at any time, nails may be fired unintentionally and cause serious injury.
4. DO NOT use the body of the tool or top cap as a hammer. Discharged fasteners may follow unexpected paths
and cause serious bodily injury.

PNEUMATIC NAILER SAFETY RULES
TOOL SAFETY
1. DO NOT FORCE THE TOOL to do a job for which it was not designed.
2. 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.
3. 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.
4. 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. DO NOT DISCHARGE FASTENERS into open air, concrete, stone, extremely hard woods, knots or any
material too hard for the fastener to penetrate.
6. 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.
7. DO NOT DRIVE FASTENERS 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.
8. BE AWARE OF MATERIAL THICKNESS when using the nailer. A protruding nail may cause injury.
9. 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.
10. REMOVE FINGER FROM TRIGGER when not driving fasteners. Never carry the tool with your finger
on the trigger.
11. IF THE FASTENERS ARE JAMMED, disconnect the tool from the air supply first before removing the
jammed fasteners.
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 magazine,
perform maintenance or clear jammed fasteners while connected to the air supply.
13. 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.
14. MAINTAIN TOOLS PROPERLY. ALWAYS keep tools clean and in good working order. Follow
instructions for lubricating, changing accessories and storage.

PREPARING THE AIR SUPPLY (Fig. 2)
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 serious personal
injury may result.
Your nailer is designed to operate on dry compressed air at the regulated pressure between 70 and 120 PSI (4.8
and 8.3 bar). Do not operate when the air pressure is outside of the recommended range. The recommended
air supply setup should include the following:
• A pressure regulator - to regulate the air pressure
• An in-line filter - to remove contaminants from the air
• An in-line automatic oiler - to keep the tool lubricated
The oiler should be located as close to the tool as possible, within 15 feet is ideal. If an in-line oiler is not avail-
able, place five or six drops of oil into the tool’s air inlet and the beginning of each work day as shown in Fig. 1.
All air supply components including hoses, connectors, filters, regulators, etc. must have a working pressure rat-
ing of at least 180 PSI (150% above the maximum operating pressure of the tool) . Refer to the diagram below
(Fig. 2) for the recommended accessories and connection order.

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 respon-
sibility. 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.
2. Turn the tool so the air inlet is facing up. Place 5 to 6 drops of
resin-free 30W non-detergent air tool lubrication oil into the air
inlet (Fig. 1). Excessive lubrication may damage the work surface.
Wipe off any excess oil from the inlet.
WARNING: To prevent injury from accidental operation, make sure the tool disconnected from the
air supply before assembly and making adjustments. Always wear Z87.1-approved safety glasses and
hearing protection during assembly, operation, and maintenance of the tool.

PREPARATION AND ADJUSTMENTS
CONNECTING TOOL TO THE AIR SUPPLY
WARNING: Connect the air supply before loading fasteners. Make sure the nailer magazine is
empty when connecting to the air supply to prevent misfire. Never aim the tip of the nailer towards
yourself or others.
To connect your nailer to a properly installed compressed air supply:
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 within this range, 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 com-
pressed 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. Check the compressed air hoses and couplings to make sure there are no leaks. Lay the compressed air hoses
flat on the ground with sufficient length of spare hose in the work area.
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.
NON-MARRING TIP (Fig. 3)
The rubber non-marring tip (Fig. 5 - 1) is attached to your nailer’s
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 accuracy and driving depth. It will also allow
better grip on the surface using the no-slip teeth. However, the
teeth may leave dents on your workpiece.
WARNING: Disconnect tool from air supply before
removing or installing the non-marring tips. Fig. 3

Step 1 - Adjust the Angle Adjustment Pin
1. The angle adjustment pin (Part No. 61731-035) is
located near the 21, 28, 34 degree marking on the left
of the nose. It has two settings, 21 degrees and 28/34
degrees.
2. To adjust the angle pin to your desired angle, first
remove the O-ring (Part No. 61731-032) from the angle
adjustment pin (If you cannot get it off with your fingers,
use a pair of tweezers). Then re-insert the pin through
the hole for the desired angle setting (Fig. 4).
3. Re-install the O-ring.
Step 2 - Adjust the Angle Adjustment Screw
1. Slide the feeder shoe (Part No. 61731-081) all the
way back along the magazine until it latches (Fig. 5).
2. Using the smallest hex wrench included, loosen and
remove the hex screw (Part No. 61731-080) on the mov-
able plate (Part No. 61731-079).
3. Move the plate so the hex screw sits in the hole of
the desired angle setting. Reinstall the hex screw and
tighten it.
Step 3 - Adjust the Angle Adjustment Wheel
1. Unscrew the angle adjustment wheel from the joint
plate by turning it counterclockwise (the locking nut for
the wheel screw is welded to the bracket and cannot be
removed).
2. Tilt the magazine to desired angle. Then re-install
and tighten the angle adjustment wheel.
WARNING: To prevent injury from accidental operation, make sure the tool is disconnected from
the air supply before assembly and making adjustments. Always wear Z87.1-approved safety glasses
