IMPORTANT SAFETY S

Important Safety Instructions

INSTRUCTIONS PERTAINING

TO A RISK OF FIRE, ELECTRIC

SHOCK, OR INJURY

TO PERSONS

WARNING – When using tools, basic

precautions should always be followed,
including the following:

General

a. To reduce the risks of electric shock,

re, and injury to persons, read all the

instructions before using the tool.

Work area

a. Keep the work area clean and well

lighted. Cluttered benches and dark

areas increase the risks of electric

shock, re, and injury to persons.

b. Do not operate the tool in explosive

atmospheres, such as in the presence

of ammable liquids, gases, or dust.
The tool is able to create sparks resulting
in the ignition of the dust or fumes.

c. Keep bystanders, children, and

visitors away while operating the tool.
Distractions are able to result in the loss
of control of the tool.

Personal safety

c. Avoid unintentional starting. Be

sure the trigger is released before
connecting to the air supply. Do not

carry the tool with your nger on the

trigger or connect the tool to the air
supply with the trigger pressed.

d. Do not overreach. Keep proper

footing and balance at all times.

Proper footing and balance
enables better control of the tool in
unexpected situations.

e. Use safety equipment. A

dust mask, non-skid safety
shoes and a hard hat must be

used for the applicable
conditions. Wear heavy-duty work
gloves during use.

f. Always wear eye protection.

Wear ANSI-approved safety

goggles with side shields.

g. Always wear hearing

protection when using the

tool. Prolonged exposure to

high intensity noise is able to
cause hearing loss.

a. Stay alert. Watch what you are

doing and use common sense when
operating the tool. Do not use the

tool while tired or under the inuence

of drugs, alcohol, or medication. A
moment of inattention while operating
the tool increases the risk of injury
to persons.

b. Dress properly. Do not wear loose

clothing or jewelry. Contain long hair.
Keep hair, clothing, and gloves away
from moving parts. Loose clothes,

jewelry, or long hair increases the risk
of injury to persons as a result of being
caught in moving parts.

h. Do not attach hose or tool to your

body. Attach hose to structure to reduce
risk of loss of balance if hose shifts.

i. Always assume that the tool contains

fasteners. Do not point the tool toward
yourself or anyone whether it contains
fasteners or not.

j. WARNING – Do not re fastener on

top of another fastener. This is able to

cause the fastener to be deected and

hit someone, or cause the tool to react
and result in a risk of injury to persons.

k. WARNING – Remove nger from the

trigger when not driving fasteners.
Never carry the tool with nger on

trigger, the tool is able to re a fastener.

Tool use and care

a. Use clamps or another practical way

to secure and support the workpiece
to a stable platform. Holding the work

by hand or against the body is unstable
and can lead to loss of control.

b. Do not force the tool. Use the correct

tool for the application. The correct tool
will do the job better and safer at the rate
for which the tool is designed.

c. Do not use tool if trigger does not turn

tool on or off. Any tool that cannot be
controlled with the trigger is dangerous
and must not be used until repaired.

d. Disconnect tool from air source

before making adjustments, doing
tool maintenance, clearing jams,
touching safety nosepiece, leaving
work area, loading, or unloading the
tool. Such precautionary measures

reduce the risk of injury to persons.

e. Store the tool when it is idle out of

reach of children and other untrained
persons. A tool is dangerous in the

hands of untrained users.

f. Maintain the tool with care. A properly

maintained tool reduces the risk of
binding and is easier to control.

g. Check for misalignment or binding

of moving parts, breakage of parts,
and any other condition that affects
the tool’s operation. If damaged,

have the tool serviced before using.
Many accidents are caused by poorly
maintained tools. There is a risk of
bursting if the tool is damaged.

h. Use only accessories that are

identied by the manufacturer for
the specic tool model. Use of an

accessory not intended for use with the

specic tool model, increases the risk of

injury to persons.

i. Use only those fasteners listed in the

Specications chart of this manual.
Fasteners not identied for use with this
tool by the tool manufacturer are able to
result in a risk of injury to persons or tool
damage when used in this tool.

Service

a. Tool service must be performed only

by qualied repair personnel.

b. When servicing a tool, use only

identical replacement parts. Use only
authorized parts.

c. Use only the lubricants supplied

with the tool or specied by

the manufacturer.

Air source

a. Never connect to an air

source that is capable of

exceeding 200 PSI. Over

pressurizing the tool may
cause bursting, abnormal operation,
breakage of the tool or serious injury to
persons. Use only clean, dry, regulated
compressed air at the rated pressure or
within the rated pressure range as
marked on the tool. Always verify prior to
using the tool that the air source has
been adjusted to the rated air pressure
or within the rated air-pressure range.

b. Never use oxygen, carbon dioxide,

combustible gases or any bottled gas
as an air source for the tool. Such

gases are capable of explosion and
serious injury to persons.

air hose is ruptured. The shutoff
valve should be a ball valve because
it can be closed quickly. See pages 8
and 9 for Air Tool Setup procedures.

Note: If an automatic oiler system is not

used, add a few drops of Pneumatic
Tool Oil into the airline connection before
operation. Add a few more drops after
each hour of continual use.

2. Attach an air hose to the compressor’s
air outlet. Connect the air hose to the
air inlet of the tool. Please note: a
quick coupler will be needed for
proper connection.

WARNING! TO PREVENT SERIOUS

INJURY FROM ACCIDENTAL
OPERATION: Do not install a quick
coupler on the tool. A coupler contains

an air valve that will allow the air tool to
retain pressure and operate accidentally
after the air supply is disconnected.

Note: Air ow, and therefore tool

performance, can be hindered by
undersized air supply components.

3. The air hose must be long enough
to reach the work area with enough
extra length to allow free movement
while working.

4. Release the tool’s Trigger (44).

5. Close the in-line safety valve between
the compressor and the tool.

6. Turn on the air compressor according to
the manufacturer’s directions and allow it
to build up pressure until it cycles off.

7. Adjust the air compressor’s output
regulator so that the air output is enough
to properly power the tool, but the output
will not exceed the tool’s maximum
air pressure at any time. Adjust the
pressure gradually, while checking

the air output gauge to set the right
pressure range.

8. The air pressure setting must not exceed
job site regulations/restrictions. The air
pressure setting must not exceed 90 PSI
when being used with work pieces that
have a thickness of less than 1-3/4”.

9. Inspect the air connections for leaks.
Repair any leaks found.

10. If the tool will not be used at this time,
turn off and detach the air supply, safely
discharge any residual air pressure,
and release the trigger to prevent
accidental operation.

Note: Residual air pressure should not be

present after the tool is disconnected
from the air supply. However, it is a
good safety measure to attempt to
discharge the tool in a safe fashion after
disconnecting to ensure that the tool is
disconnected and unpowered.

Nail Penetration Depth Adjustment

1. With the tool connected to its air supply

and with the nails loaded, test re on a

scrap material (similar to the workpiece)
and note the depth of nail’s penetration.

2. To adjust nail depth penetration, rotate
the Depth Knob (52). Turn the Depth
Knob to the left (+) for deeper nail
penetration and to the right (-) for more
shallow penetration.

3. CAUTION! When working with asphalt
shingles in particular, the nail head
should not sink below the top face of
the shingle.

not re if the nose is not depressed.
Once depressed, gently and briey

squeeze the Trigger once. Do not re
repeatedly. Nails could bounce off of
one another, damaging the workpiece or
causing PERSONAL INJURY.

5. If the tool requires more force to
accomplish the task, verify that the

tool receives sufcient, unobstructed
airow (CFM) and increase the pressure

(PSI) output of the regulator up to the
maximum air pressure rating of this tool.

CAUTION! TO PREVENT TOOL AND
ACCESSORY FAILURE, RESULTING
IN INJURY: Do not exceed the tool’s
maximum air pressure rating.

If the tool still does not have sufcient

force at maximum pressure and

sufcient airow, then a larger tool may

be required.

Note: While working on roofs, tar and

dirt may build up on the Nose of the

Roong Nailer. This can prevent normal

operation. Remove buildup with a

nonammable solvent. NEVER use
gasoline or other ammable solvents.
Do not immerse the Roong Nailer in

an approved solvent beyond the height
of the nail heads, to avoid getting the
solvent into the drive cylinder of the

tool. Dry off the Roong Nailer before
use; any oil lm left after cleanup will

accelerate tar buildup.

6. After use, to prevent accidents:

a. Release the trigger.

b. Detach the air supply.

c. Attempt to re the Tool into a piece

of scrap wood to ensure that it is

incapable of ring any fasteners.

d. Release the trigger again.

e. Clean external surfaces with clean,

dry cloth.

f. Store indoors out of children’s reach.
