GENERAL SAFETY RULES  
nDo not overreach. Keep proper footing and balance  
at all times. Proper footing and balance enables better  
control of the tool in unexpected situations.  
DANGER  
READ AND UNDERSTAND TOOL LABELS AND  
MANUAL. Failure to follow warnings could result  
in DEATH or SERIOUS INJURY.  
nUse safety equipment. Always wear eye protection.  
Dust mask, nonskid safety shoes, hard hat, or hearing  
protection must be used for appropriate conditions.  
nDo not use on a ladder or unstable support. Stable  
footing on a solid surface enables better control of the

SAVE THESE INSTRUCTIONS  
WORK AREA  
nKeep your work area clean and well lit. Cluttered  
TOOL USE AND CARE  
benches and dark areas invite accidents.  
nDo not force tool. Use the correct tool for your  
application. The correct tool will do the job better and  
safer at the rate for which it is designed.  
nDo not operate power tools in explosive atmospheres,  
such as in the presence of flammable liquids, gases,  
or dust. Power tools create sparks which may ignite the  
dust or fumes.  
nDo not use tool if trigger does not actuate properly.  
Any tool that cannot be controlled with the trigger is  
dangerous and must be repaired.  
nKeep bystanders, children, and visitors away while  
operating a power tool. Distractions can cause you to  
lose control.  
nCheck operation of the workpiece contact mechanism  
frequently. Do not use the tool if the workpiece contact  
mechanism is not working correctly as accidental driving  
of a fastener may result. Do not interfere with the proper  
operation of the workpiece contact mechanism.  
PERSONAL SAFETY  
nEye 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 others in the work area when  
loading, operating or servicing this tool. Eye protection  
is required to guard against flying fasteners and debris,  
which could cause severe eye injury.  
nStore idle tools out of the reach of children and other  
untrained persons. Tools are dangerous in the hands of  
untrained users.  
nMaintain tools with care. Follow maintenance instruc-  
tions. Properly maintained tools are easier to control.  
nThe employer and/or user must ensure that proper  
eye protection is worn. We recommend Wide Vision  
Safety Mask for use over eyeglasses or standard safety  
glasses that provide protection against flying particles  
both from the front and side. Always use eye protection  
which is marked to comply with ANSI Z87.1.  
nCheck for misalignment or binding of moving parts,  
breakage of parts, and any other condition that may  
affect the tool’s operation. If damaged, have the tool  
serviced before using. Many accidents are caused by  
poorly maintained tools.  
nUse only fasteners that are recommended for your  
nAdditional safety protection will be required in some  
environments. For example, the working area may in-  
clude exposure to noise level which can lead to hearing  
damage. The employer and user must ensure that any  
necessary hearing protection is provided and used by the  
operator and others in the work area. Some environments  
will require the use of head protection equipment. When  
required, the employer and user must ensure that head  
protection conforming to ANSI Z89.1-1997 is used.  
model.  
nKeep the tool and its handle dry, clean and free from  
oil and grease. Always use a clean cloth when clean-  
ing. Never use brake fluids, gasoline, petroleum-based  
products, or any strong solvents to clean your tool. Fol-  
lowing this rule will reduce the risk of loss of control and  
deterioration of the enclosure plastic.  
SERVICE  
nTool service must be performed only by qualified re-  
pair personnel. Service or maintenance performed by  
unqualified personnel may result in a risk of injury.  
nStay alert, watch what you are doing and use common  
sense when operating a power tool. Do not use tool  
while tired or under the influence of drugs, alcohol,  
or medication. A moment of inattention while operating  
power tools may result in serious personal injury.  
nWhen servicing a tool, use only identical replacement  
parts. Follow instructions in the Maintenance sec-  
tion of this manual. Use of unauthorized parts or failure  
to follow Maintenance instructions may create a risk of  
injury.  
nDress properly. Do not wear loose clothing or jewelry.  
Contain long hair. Keep your hair, clothing, and gloves  
away from moving parts. Loose clothes, jewelry, or long  
hair can be caught in moving parts.  
n

eration is dusty. Following this rule will reduce the risk of  
serious personal injury.  
OPERATION  
nAlways assume that the tool contains fasteners.  
nProtect your hearing. Wear hearing protection during  
extended periods of operation. Following this rule will  
reduce the risk of serious personal injury.  
nDo not carry the tool from place to place holding the  
trigger. Accidental discharge could result.  
nAlways handle the tool with care:  
• Respect the tool as a working implement.  
• Never engage in horseplay.  
nMake sure the hose is free of obstructions or snags.  
Entangled or snarled hoses can cause loss of balance or  
footing and may become damaged.  
nUse the tool only for its intended use. Do not discharge  
• Never pull the trigger unless nose is directed toward  
the work.  
fasteners into open air.  
nDo not drive fasteners near edge of 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 un-  
expectedly from the side of the work material.  
• Keep others a safe distance from the tool while tool is in  
operation as accidental actuation may occur, possibly  
causing injury.  
nChoice of triggering method is important. Check  
manual for triggering options.  
nKeep hands and body parts clear of immediate work  
area. Hold workpiece with clamps when necessary to  
keep hands and body out of potential harm. Be sure the  
workpiece is properly secured before pressing the nailer  
against the material. The workpiece contact may cause  
the work material to shift unexpectedly.  
nDo not point the tool toward yourself or anyone  
whether it contains fasteners or not.  
nDo not actuate the tool unless you intend to drive a  
fastener into the workpiece.  
nDuring normal use the tool will recoil immediately after  
driving a fastener. This is a normal function of the tool.  
Do not attempt to prevent the recoil by holding the nailer  
against the work. Restriction to the recoil can result in  
a second fastener being driven from the nailer. Grip the  
handle firmly and let the tool do the work. Failure to heed  
this warning can result in serious personal injury.  
nKeep face and body parts away from 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.  
nUse the pneumatic tool only for the purpose for which  
it was designed.  
nNever use this tool in a manner that could cause a  
fastener to be directed toward anything other than  
the workpiece.  
nDo not use the tool as a hammer.  
nAlways carry the tool by the handle. Never carry the

nDo 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.  
nDo not drive fasteners close to the edge of the  
workpiece as the wood may split, allowing the fas-  
tener to be deflected possibly causing injury.  
nDo not alter or modify this tool from the original design  
or function without approval from the manufacturer.

MAINTENANCE  
LUBRICATION  
Frequent, but not excessive, lubrication is required for  
best performance. Oil for pneumatic fastening tools added  
through the air line connection will lubricate the internal parts.  
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.  
WARNING:  
When servicing use only identical RIDGID  
replacement parts. Use of any other parts may  
create a hazard or cause product damage.  
WARNING:  
Always wear safety goggles or safety glasses with  
side shields during power tool operation or when  
blowing dust. If operation is dusty, also wear a  
dust mask.  
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 air tool lubricant or permanent  
antifreeze (ethylene glycol) as a cold weather lubricant.  
WARNING:  
Disconnect the tool from the air supply before  
performing maintenance. Failure to do so could  
result in serious personal injury.  
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.  
GENERAL MAINTENANCE  
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.  
Avoid using solvents when cleaning plastic parts. Most  
plastics are susceptible to damage from various types of  
commercial solvents and may be damaged by their use. Use  
clean cloths to remove dirt, dust, oil, grease, etc.  
AIR SUPPLY-PRESSURE AND VOLUME  
Air volume is as important as air pressure. The air volume  
supplied to the tool may be inadequate because of under-  
size fittings and hoses, or from the effects of dirt and water  
in the system. Restricted air flow will prevent the tool from  
receiving an adequate volume of air, even though the pres-  
sure reading is high. The results will be a slow operation or  
reduced driving power. Before evaluating tool problems for  
these symptoms, trace the air supply from the tool to the  
supply source for restrictive connectors, low points contain-  
ing water and anything else that would prevent full volume  
flow of air to the tool.  
WARNING:  
Do not at any time let brake fluids, gasoline,  
petroleum-based products, penetrating oils, etc.,  
come in contact with plastic parts. Chemicals can  
damage, weaken or destroy plastic which may  
result in serious personal injury.
