SAFETY INSTRUCTIONS

EYE PROTECTION which conforms to ANSI specifications and provides protection against
flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and
o

thers in the work area when connecting to air supply, loading, operating or servicing this

t

ool. Eye protection is required to guard against flying fasteners and debris, which could

cause severe eye injury.
T

he employer and/or user must ensure that proper eye protection is worn. Eye protection

e

quipment must conform to the requirements of the American National Standards Institute,
ANSI Z87.1 and provide both frontal and side protection. NOTE: Non-side shielded
spectacles and face shields alone do not provide adequate protection.

CAUTION:

Additional Safety Protection will be required in some environments. For example,
the working area may include exposure to noise level which can lead to hearing damage.
The employer and user must ensure that any necessary hearing protection is provided and
u

sed by the operator and others in the work area. Some environments will require the use

o

f head protection equipment.When required, the employer and user must ensure that head

protection conforming to ANSI Z89.1 is used.

AIR SUPPLY AND CONNECTIONS

Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as
tool may explode, possibly causing injury.

Do not use supply sources which can potentially exceed 200 P.S.I.G. as tool may burst,
possibly causing injury.

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.

Do not pull trigger while connected to the air supply as the tool may cycle, possibly causing
injury.

Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing the tool;

3.) When clearing a jam; 4.) When tool is not in use; 5.) When moving to a different work area,
as accidental actuation may occur, possibly causing injury; 6.) Before placing tool on any
surface, hanging tool on belt, or otherwise temporarily supsending use of the tool.

LOADING TOOL

When loading tool: 1.) Never place a hand or any part of body in fastener discharge area of
tool; 2.) Never point tool at anyone; 3.) Do not pull the secondary trigger as accidental
actuation may occury, possibly casuing injury.

OPERATION

Always handle the tool with care: 1.) Never engage in horseplay; 2.) Never pull or grasp the
secondary trigger unless nose is directed toward the work; 3.) Keep others a safe distance
from the tool while tool is in operation as accidental actuation may occur, possibly causing
injury.

The operator must not hold the secondary trigger pulled except during fastening operation
as serious injury could result if the trigger accidentally contacts someone or something,
causing the tool to cycle.

Keep hands and body away from the discharge area of the tool.
Check operation of the secondary trigger mechanism frequently. Do not use the tool if the

secondary trigger is not working correctly as accidental driving of a fastener may result. Do
not interfere with the proper operation of the secondary trigger mechanism.

Never inadvertently pull or grasp the secondary trigger when moving about, changing work
location, when holstering or hanging tool, or when preparing work surface for fastening
operation.

Do not drive fasteners on top of other fasteners or with the tool at an overly steep angle as
this may cause deflection of fasteners which could cause injury.

Do not drive fasteners close to the edge of the work piece as the wood may split, allowing
the fastener to be deflected possibly causing injury.

This nailer produces SPARKS during operation. NEVER use the nailer near flammable
substances, gases or vapors including lacquer, paint, benzine, thinner, gasoline, adhesives,
mastics, glues or any other material that is -- or the vapors, fumes or byproducts of which are -­flammable, combustible or explosive. Using the nailer in any such environment could cause an
EXPLOSION resulting in personal injury or death to user and bystanders.

TOOL SPECIFICATIONS

All screws and nuts are metric.

FASTENER SPECIFICATIONS:

TOOL AIR FITTING:

This tool uses a free-flow connector plug, 1/4” N.P.T.The minimum inside diameter should be .200” (5mm).
The fitting must be capable of discharging tool air pressure when disconnected from the air supply.

OPERATING PRESSURE:

70 to 100 p.s.i. (4.9 to 7.1 kg/cm2). Select the operating pressure within this range for best fastener
performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.

AIR CONSUMPTION:

Model HP118K requires 1.86 cubic feet per minute (.053 cubic meters) of free air to operate at the rate of 100
fasteners per minute, at 80 p.s.i. (5.6kg/cm2). Take the actual rate at which the tool will be run to determine the
amount of air required. For instance, if your fastener usage averages 50 fasteners per minute, you need 50%
of the tool's c.f.m. of free air which is required for running at 100 fasteners per minute.

MAINTAINING THE TOOL

W

hen working on air tools note the warnings in this manual and use extra care when

e

valuating problem tools.

-5-

AIR SUPPLY AND CONNECTIONS

Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as
tool may explode, possibly causing injury.

FITTINGS:

I

nstall a male plug on the tool which is free flowing and which will release air pressure from the tool when

disconnected from the supply source.

HOSES:

Air hoses should have a minimum of 150 p.s.i. (10.6 kg/cm2) working pressure rating or 150 percent of the
m

aximum pressure that could be produced in the air system. The supply hose should contain a fitting that will

provide “quick disconnecting” from the male plug on the tool.

SUPPLY SOURCE:

Use only clean regulated compressed air as a power source for this tool. NEVER USE OXYGEN, COMBUSTIBLE
G

ASES, OR BOTTLED GASES, AS A POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE.

REGULATOR:

A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 KG/CM2) is required to control the
operating pressure for safe operation of this tool. Do not connect this tool to air pressure which can potentially
exceed 200 p.s.i. (14 KG/CM

2

) as tool may fracture or burst, possibly causing injury.

OPERATING PRESSURE:

Do not exceed recommended maximum operating pressure as tool wear will be greatly increased. The air
supply must be capable of maintaining the operating pressure at the tool. Pressure drops in the air supply can
reduce the tool’s driving power. Refer to “TOOL SPECIFICATIONS” for setting the correct operating pressure
for the tool.

FILTER:

Dirt and water in the air supply are major causes of wear in pneumatic tools. A filter will help to get the best
performance and minimum wear from the tool. The filter must have adequate flow capacity for the specific
installation. The filter has to be kept clean to be effective in providing clean compressed air to the tool. Consult
the manufacturer’s instructions on proper maintenance of your filter. A dirty and clogged filter will cause a
pressure drop which will reduce the tool’s performance.

LUBRICATION

Frequent, but not excessive, lubrication is required for best performance. Oil added through the air line
connection will lubricate the internal parts. Use BOSTITCH AirTool Lubricant, Mobil Velocite #10, or equivalent.
Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seals and bumpers
in the tool, resulting in poor tool performance and frequent tool maintenance.

If no airline lubricator is used, add oil during use into the air fitting on the tool once or twice a day. Only a few
drops of oil at a time is necessary. Too much oil will only collect inside the tool and will be noticeable in the
exhaust cycle.

COLD WEATHER OPERATION:

For cold weather operation, near and below freezing, the moisture in the air line may freeze and prevent tool
operation. We recommend the use of BOSTITCH WINTER FORMULA air tool lubricant or permanent
antifreeze (ethylene glycol) as a cold weather lubricant.

CAUTION: Do not store tools in a cold weather environment to prevent frost or ice formation on the
tools operating valves and mechanisms that could cause tool failure.

NOTE:Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use these
low temperature air dryers without checking compatibility.
