Safety Information
WARNING:
BEFORE USING THE TOOL, READ CAREFULLY AND UNDERSTAND
THE FOLLOWING SAFETY INSTRUCTIONS.FAILURE TO FOLLOW
WARNING COULD RESULT IN SERIOUS INJURY.
1. WEAR SAFETY GLASSES OR GOGGLES.
Danger to the eyes always exists due to the possibility of dust being blown
up by the exhausted air or of a fastener flying up due to the improper
handling of the tool. For these reasons, safety glasses or goggles shall
always be worn when operating the tool. The employer and/or user must
ensure that proper eye protection is worn. Eye protection equipment must
confirm to the requirements of the American National Standards Institute,
ANSI Z87.1 (Council Directive 89/686/EEC of 21 DEC.1989) and provide both
frontal and side protection.
The employer is responsible to enforce the use of eye protection equipment
by the tool operator and all other personnel in the work area.
NOTE: Non-side shielded spectacles and face shields alone do not provide
adequate protection.
2. EAR PROTECTION MAY BE REQUIRED IN SOME ENVIRONMENTS.
As the working condition may include exposure to high noise levels which can
lead to hearing damage, the employer and user should ensure that any
necessary hearing protection is provided and used by the operator and others
in the work area.
3. DO NOT USE ANY POWER SOURCE EXCEPT AN AIR COMPRESSOR.
The tool is designed to operate on compressed air. Do not operate the tool on
any other high pressure gas, combustible gases (e.g.,0Xy gen, acetylene,etc)
since there is the danger of an explosion. For this reason, absolutely do not
use anything other than an air compressor to operate the tool.
4. OPERATE WITHIN THE PROPER AIR PRESSURE RANGE.
The tool is designed to operate within an air pressure range of 70 p.s.i. to
120 p.s.i.(5 to 8 bar.). The pressure should be adjusted to the type of the
work being fastened. The tool shall never be operated when the operating
pressure exceeds 120 p.s.i. (8 bar).Never connect the tool to air pressure
which potentially exceeds 200 p.s.i. (14 bar) as the tool can burst.
5. DO NOT OPERATE THE TOOL NEAR A FLAMMABLE SUBSTANCE.
Never operate the tool near a flammable substance
(e.g., thinner, gasoline, etc). Volatile fumes from these substances could be
drawn into the compressor and compressed together with the air and this
could result in an explosion.
15°Pneumatic Coil Nailer Model No.: MCN 90
Safety Information
6. DO NOT USE A WRONG FITTING.
The connector on the tool must not hold pressure when air supply is
disconnected. If a wrong fitting is used, the tool can remain charged with air
after disconnecting and thus will be able to drive a fastener even after the
air line is disconnected, possibly causing injury.
7. DISCONNECT THE AIR SUPPLY AND EMPTY THE MAGAZINE WHEN
THE TOOL IS NOT IN USE.
Always disconnect the air supply from the tool and empty the magazine when
operation has been completed or suspended, when unattended, moving to a
different work area, adjusting, disassembling, repairing and when clearing a
jammed fastener.
8. INSPECT SCREW TIGHTNESS.
Loose or improperly installed screws or bolts cause accidents and tool damage
when the tool is put into operation. Inspect to confirm that all screws and
bolts are tight and properly installed prior to operating the tool.
9. DO NOT TOUCH THE TRIGGER UNLESS YOUR INTEND TO
DRIVE A FASTENER.
Whenever the air supply is connected to the tool, never touch the trigger
unless you intend to drive a fastener into the work. It is dangerous to walk
around carrying the tool with the trigger pulled, and this and similar actions
should be avoided.
10. NEVER POINT THE DISCHARGE OUTLET TOWARD YOURSELF
AND PERSONNEL.
If the discharge outlet is pointed toward people, serious accidents may be
caused when misfiring. Be sure the discharge outlet is not pointed toward
people when connecting and disconnecting the hose. Loading and not loading
the fasteners or similar operations.
11. USE SPECIFIED FASTENERS.
The use of fasteners other than specified fasteners will cause the tool
malfunction. Be sure to use only specified fasteners when operating the tool.
12. PLACE THE DISCHARGE OUTLET TO THE WORK PROPERLY.
Failure to place the discharge outlet of the nose in a proper manner can
result in a fastener flying up and is extremely dangerous.
13. KEEP HANDS AND BODY AWAY FROM THE DISCHARGE OUTLET
When loading and using the tool, never place a hand or any part of body in
fastener discharge area of the tool. It is very dangerous to hit the hands or
body by mistake.
15°Pneumatic Coil Nailer Model No.: MCN 90
Safety Information
14. DO NOT DRIVE FASTENERS CLOSE TO THE EDGE AND CORNER OF
THE WORK AND THIN MATERIAL
The work piece is likely to split and the fastener could fly and hit someone.
15. DO NOT DRIVE FASTENERS ON THE TOP OF OTHER FASTENERS.
Driving fasteners on the top of other fasteners may cause deflection of
fasteners which could cause injury.
16. REMOVING THE FASTENERS AFTER COMPLETING OPERATION
If fasteners are left in the magazine after the completion of operation, there
is the danger of a serious accident occurring prior to the resumption of
operation, should the tool be handled carelessly, or when connecting the air
fitting. For this reason, always remove all fasteners remaining in the
magazine after completion of the operation.
17. CHECK OPERATION OF THE CONTACT TRIP MECHANISM
FREQUENTLY IN CASE OF USING A CONTACT TRIP TYPE TOOL
Do not use the tool if the trip is not working correctly as accidental driving of
a fastener may result. Do not interfere with the proper operation of the
contact trip mechanism.
18. WHEN USING THE TOOL OUTSIDE OR ELEVATED PLACE.
When fastening roofs or similar slanted surface, start fastening at the lower
part and gradually work your way up. Fastening backward is dangerous as you
may loose your foot place. Secure the hose at a point close to the area you
are going to drive fasteners. Accidents may be caused due to the hose being
pulled inadvertently or getting caught.
19. NEVER USE THE TOOL IF ANY PORTION OF THE TOOL CONTROLS
(e.g., TRIGGER, CONTACT ARM) IS INOPERABLE DISCONNECTED,
ALTERED OR NOT WORKING PROPERLY.
20. NEVER ACTUATE THE TOOL INTO FREE SPACE.
This will avoid any hazard caused by free flying fasteners and excessive
strain of the tool.
21. ALWAYS ASSUME THAT THE TOOL CONTAINS FASTENERS.
Employer's Responsibilities

Nailer Connection and Operation
NOTE: The information contained in this manual is designed to assist you
in the safe operation of the nailer. Some illustrations in this manual may show
details or attachments that are different from those on your nailer.
Air Supply, Connections and Operating Pressure
Read section titled SAFETY. Make sure of the following before operation:
Air Supply
Power Source (Compressor)
о Use only clean, dry, regulated compressed air as a power source for
this nailer.
о NEVER use oxygen or other bottled gases, as an explosion may occur.
о Air compressors used to supply compressed air to this nailer must
comply with the requirements of the latest version of ANSI Standard
B 19.3 Safety Standard for compressors for Process Industries.
о Moisture or oil in the air compressor may accelerate wear and
corrosion in the nailer.
o Drain daily.
Quick Connector Air Hose Quick Connector
Regulator
Connections
1. Fittings
Install a female coupler to the hose. The female coupler will connect to
the quick release that fits the tool.
2. Filter-Regulator-Lubricator
© NEVER connect nailer to pressure which potentially exceeds 150psi.
о Filter-regulator-lubricator units supply an optimum condition for the
nailer and extend the nailer life. These units should always be used.
Filter
о The filter removes moisture and dirt mixed in compressed air.
o Keep the filter clean by maintaining tool regularly.
o Drain daily.
Regulator
о The regulator controls the operating pressure for safe operation of
the nailer.
о Inspect the regulator before operation to be sure it operates properly.
15°Pneumatic Coil Nailer Model No.: MCN 90
Nailer Connection and Operation
Lubricator
The lubricator supplies and oil mist to the nailer.
Inspect the lubricator before operation to be sure the supply of
lubricant is adequate.
If an inline lubricator is not used, a few drops of oil will need to be
added to the nailer inlet before each use.
3. Air Hose
Air hose must have a minimum working pressure rating of 150psi or 150%
of the maximum pressure produced in the system, whichever is higher.
Hose has a min. ID of 1/4" and max. length of not more than 17'(5 meter).
The supply hose should contain a fitting that will provide "quick
disconnecting” from the male plug on the tool.
Operating Pressure
Recommended operating pressure range is 70 to 100 psi.
Maximum permissible operating pressure is 150 psi.
Select the operating pressure within this range for the best fastener
performance. The nail length and thickness and the hardness of the
wood are factors in determining what the pressure should be set at.
Do not exceed this recommended operating pressure.
NOTE:Dirt and water in the air supply are major causes of wear in the tool.
An air filter will help to get the best performance and minimum wear from the
tool. Frequent, but not excessive, lubrication is required for the best
performance. Oil added through the air line connection will lubricate the internal
parts.
WARNING
NEVER connect nailer to pressure which potentially exceed 150psi.
DO NOT USE THE WRONG FITTING ON NAILER.
The nailer and air hose must have a hose coupler so that all
pressure is removed from the nailer when the coupler is
disconnected. The connector on the tool must not hold
pressure when the air supply is disconnected. If the wrong
fitting is used, the tool can remain charged with air after
disconnecting and thus will be able to drive a nail even
after the air line is disconnected, possibly causing injury.
DANGER
NEVER use oxygen or other bottled gases, as an explosion may
occur.
