Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be

followed to reduce the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

Keep work area clean. Cluttered areas invite injuries.

Observe work area conditions. Do not use machines or power tools in damp or

wet locations. Do not expose to rain. Keep work area well lit. Do not use electri-

cally powered tools in the presence of ﬂammable gases or liquids.

Keep children away. Children must never be allowed in the work area. Do not let

them handle machines, tools, extension cords, or air hoses.

Store idle equipment. When not in use, tools must be stored in a dry location to

inhibit rust. Always lock up tools and keep out of reach of children.

Use the right tool for the job. Do not attempt to force a small tool or attachment

to do the work of a larger industrial tool. There are certain applications for which

this tool was designed. It will do the job better and more safely at the rate for which

REV 09/05; 12/05

it was intended. Do not modify this tool and do not use this tool for a purpose for

which it was not intended.

Dress properly. Do not wear loose clothing or jewelry as they can be caught in

moving parts. Protective, electrically nonconductive clothes and nonskid foot

wear are recommended when working. Wear restrictive hair covering to contain

long hair.

Do not overreach. Keep proper footing and balance at all times. Do not reach

over or across running machines or air hoses.

Use eye and ear protection. Always wear ANSI-approved impact

safety goggles and appropriate hearing protection. Wear a full face shield

if you are producing metal ﬁlings or wood chips. Wear a NIOSH-approved

dust mask or respirator when working around metal, wood, and chemi-

cal dusts and mists. Other people in the work area must also wear ANSI-approved

impact safety goggles.

Maintain tools with care. Keep tools clean for better and safer performance. Fol-

low instructions for lubricating and changing accessories. Inspect tool cords and

air hoses periodically and, if damaged, have them repaired by a qualiﬁed techni-

cian. The handle must be kept clean, dry, and free from oil and grease at all times.

Do not operate a tool if any portion of the tool’s operating controls are inoperable,

disconnected, altered or not working properly.

Disconnect Air Hose and release any built-up air pressure. Never service the

Nailer, clear jams, or disassemble with the air hose attached. Always release any

built-up air even after disconnecting hose. Disconnect the Nailer when not in use.

Remove adjusting keys and wrenches. Check that keys and adjusting wrenches

are removed from the tool or machine work surface before attaching to an air

source.

Avoid unintentional starting. Be sure the trigger is in the Off position when not

in use and before plugging in. Do not carry any tool with your ﬁnger on the trigger,

whether it is attached to an air source or not. Do not point the tool towards yourself

or anyone whether it contains fasteners or not.

Stay alert. Watch what you are doing, use common sense. Do not operate any

tool when you are tired.

Check for damaged parts. Before using any tool, any part that appears damaged

should be carefully checked to determine that it will operate properly and perform

its intended function. Check for alignment and binding of moving parts; any broken

parts or mounting ﬁxtures; and any other condition that may affect proper operation.

Any part that is damaged should be properly repaired or replaced by a qualiﬁed

technician. Do not use the tool if the trigger does not operate properly.

Guard against electric shock. Prevent body contact with grounded surfaces such

as pipes, radiators, ranges, and refrigerator enclosures.

Replacement parts and accessories. This product is to be repaired and serviced

only by a qualiﬁed technician. When this product is serviced, only identical replace-

ment parts should be used. Use of any other parts will void the warranty. Only use

accessories intended for use with this tool. Approved accessories are available

from Harbor Freight Tools.

Do not operate tool if under the inﬂuence of alcohol or drugs. Read warning

labels if taking prescription medicine to determine if your judgement or reﬂexes are

impaired while taking drugs. If there is any doubt, do not operate the tool.

Use proper size and type extension cord. If an extension cord is required for the

air compressor, it must be of the proper size and type to supply the correct current

to the compressor without heating up. Otherwise, the extension cord could melt

and catch ﬁre, or cause electrical damage to the tool. Check your air compressor’s

manual for the appropriate size cord. It is also possible that the use of an exten-

sion cord may cause your circuit breaker to trip or your panel fuse to break. If this

happens, either use the compressor without an extension cord or ﬁnd a larger

amperage circuit to use.

Maintenance. The maintenance outlined in the maintenance section should be

performed regularly. For your safety, this product should be serviced or repaired

regularly only by a qualiﬁed technician.

Compressed air only. Never use combustible gas as a power source.

Do not load nails with the trigger or safety depressed. Uninten-

tional ﬁring may occur. Do not load nails when the air hose is con-

nected to the tool. Always assume the tool contains fasteners.

Disconnect air supply before loading the Nailer. Before reloading (or making

any adjustments to) the Nailer, make sure the compressed air is disconnected.

Fire fasteners into an appropriate work surface only. Do not attempt to ﬁre

fasteners into surfaces too hard to penetrate. Do not drive fasteners on top of other

fasteners, or at too steep an angle. Fasteners can ricochet causing personal injury.

Never ﬁre the Nailer into the air, or point it toward yourself or another person. Always

wear ANSI approved safety goggles during use, maintenance, and reloading.

Do not ﬁre fasteners too close to the edge of a workpiece. They may split the

workpiece and ﬂy free, causing personal injury.

Take caution, as some woods contain preservatives such as copper chromium

arsenate (CCA) which can be toxic. When stapling or nailing these materials extra

care should be taken to avoid inhalation and minimize skin contact.

Operating the Nailer

Attach the Nailer to the air supply at the Air Plug (83). Start your compressor and

check the pressure making sure it is set at the recommended 70-100 PSI and not

to go over the maximum 100 PSI.

To ﬁre, place the nose of the Nailer on the workpiece. The Nailer should not ﬁre if

the nose is not depressed. Once depressed, gently and brieﬂy squeeze the Trigger

(73) once. Do not ﬁre repeatedly. Nails could bounce off of one another, damag-

ing the workpiece or causing PERSONAL INJURY.

Caution: When the Trigger (73) is depressed, the Rooﬁng Nailer will ﬁre if the Nose

of the tool comes in contact with anything.

SKU 92917 & 93253 For technical questions, please call 1-800-444-3353. Page 10

Do not press the Nose of the Rooﬁng Nailer against the work surface with extra force.

Allow the tool to do the work. Always allow the tool to recoil off the workpiece.

Caution: While working on roofs, tar and dirt may build up on the Nose of the Roof-

ing Nailer. This can prevent normal operation. Remove buildup with a nonﬂammable

solvent. NEVER use gasoline or other ﬂammable solvents. Do not immerse the

Rooﬁng Nailer in an approved solvent beyond the height of the nail heads, to avoid

getting the solvent into the drive cylinder of the tool. Make sure to dry off the Roof-

ing Nailer before use. Any oil ﬁlm left after cleanup will accelerate tar buildup.

When ﬁnished using the Rooﬁng Nailer, always disconnect the tool from its com-

pressed air supply. Empty the Nail Canister (90) completely of nails. Attempt to

ﬁre the Rooﬁng Nailer into a piece of scrap wood to ensure it is disconnected and

is incapable of ﬁring any nails. Always leave the Nail Canister open during this

procedure. The Canister is spring loaded and may cause parts or a nail to ﬂy

out of the Rooﬁng Nailer.

Make sure to store the Rooﬁng Nailer in its accessory Carrying Case and in a clean,

dry, safe location out of reach of children.
