Important Safety Information (Continued)

Personal Safety

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 influence 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.

c. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

d.Use safety equipment. A dust mask, non-skid safety shoes and a hard hat must be used for the applicable conditions.

Ensuring that the tool is used only when the operator and all

other personnel in the work area are wearing ANSI Z87 eye protection equipment, and when required, other appropriate protection equipment such as head, hearing

and foot protection equipment. Serious eye or permanent hearing loss could result.

e.Always wear hearing protection when using the tool. Prolonged exposure to high intensity noise is able to cause hearing loss.

f.Do not attach the hose or tool to your body.

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

g.Always assume that the tool contains fasteners.

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

Do not drop or throw the tool. Dropping

or throwing the tool can result in damage that will make the tool unusable or unsafe. If the tool has been dropped or thrown, examine the tool closely for bent, cracked or broken parts and air leaks. STOP and repair before using or serious injury could occur.

Avoid long extended periods of work with the nailer. Stop using the nailer if you feel pain in

hands or arms.

Hold tool by insulated gripping surface when performing an operation where the tool or

fastener may contact hidden wiring. Contacting a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

Never place hands or any other body parts in the nail discharge

area of the nailer.The nailer might eject a fastener and could result in death or serious personal injury.

Electrical Safety

Replace batteries only with same size batteries. Do not mix old and new batteries. Using wrong size batteries can create a risk

of fire or injury.

The front end of the tool may be made “live” if the tool comes

into contact with live wiring in the wall.TO PREVENT ACCIDENTAL ELECTRICAL SHOCK, HOLD TOOL ONLY BY THE SOFT GRIP HANDLE.

Tool Use and Care

a.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.

Disconnect the tool from the air source before making adjustments, doing tool maintenance,

clearing jams, touching the safety yoke, leaving work area, loading, or unloading the tool. Such precautionary measures reduce the risk of injury to persons.

b.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.

c.Maintain the tool with care. A properly maintained tool reduces the risk of problems and is easier to control.

d.Use only those fasteners listed in the “Fastener Interchange Information” section on page 12 of this manual. Fasteners not identified 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.

e.Always work in a well-ventilated area.Wear OSHAapproved dust mask.

Always disconnect the tool from the power source when unattended, performing any

maintenance or repair, clearing a jam, loading, unloading , or moving the tool to a new location.

Always fit tool with a fitting or hose coupling on or near the tool in such a manner that all

compressed air in the tool is discharged at the time the fitting or hose coupling is disconnected. Do not use a check valve or any other fitting which allows air to remain in the nailer. Death or serious personal injury could occur.

Never carry the nailer by the air hose or pull the hose to move the nailer or a compressor.

Keep hoses away from heat, oil and sharp edges. Replace any hose that is damaged, weak or worn. Personal injury or tool damage could occur.

Do not drive a nail on top of other nails.The nail could glance and cause death or a serious

puncture wound.

Do not expose tool to extreme heat.

f.Do not store in locations where the temperature may reach or exceed 120°F (49°C), such as a metal tool shed, or a car in the summer.This can lead to deterioration of the battery.

Pre-Operation

Operational Modes

Always know the operational mode of the nailer before using. Failure to know the operational mode could result in death or serious injury.

This nailer may be operated in the “Sequential” mode (as supplied by the manufacturer) or “Bump” mode. The tool may be converted from one mode to the other by firmly pressing the conversion switch from one position to the other.

Press the conversion switch on the “ ” side to activate Sequential Mode.

Press the conversion switch on the “ ” side to activate Bump Mode. Press either side to the middle position to activate the Safety Lockout Mode.

Sequential Mode

This method is recommended when precise nail placement is required. Operation in this mode requires trigger to be pulled each time a nail is driven. Nailer can be actuated by depressing the Work Contact Element (WCE) against work surface followed by pulling the trigger.

The trigger must be released after each fastener is driven to allow tool to reset.

Since the tool can only be actuated by first removing the finger from the trigger, this is considered to be a more restrictive mode of operation, suitable for less experienced users.

Depress WCE first...

Low Nail Indicator Lights

The tool is equipped with lights on either side of the tool near the nose. Turn the electronics switch to the on position. When the nail count becomes 10 or so nails remaining in the magazine, the lights will come on yellow. You may reload at that time (See Loading the Nailer section). When the nail count becomes 5 or so remaining nails, the Anti-Dry Fire will engage and the lights will turn red. You must reload at that time.

Bubble Level

The tool is equipped with a bubble level located on the head cap. When the gun is in a horizontal driving orientation, a level condition can easily be observed and controlled by simply aligning the tool in such a manner whereas the bubble is between the center markings on the length of the level. The same is true when in a vertically downward driving orientation by aligning the tool such that the bubble is centered in the circular marking at the top of the level.

Nailer Repair

Only qualified personnel should repair the tool and they should use genuine Campbell Hausfeld replacement parts and accessories, or parts and accessories which perform equivalently.

Replacement Parts

Use only genuine Campbell Hausfeld service parts.Tool performance, safety and durability could be reduced if improper parts are used.

When ordering replacement parts, specify by part number.

Battery Replacement

Always disconnect the tool from the power source when unattended, performing any maintenance or repair, clearing a jam, loading,

unloading, or moving the tool to a new location.

The electronics on the tool (low nail indicator lights) run off of two (2) AAA batteries located in the compartment on the back of the magazine. When the batteries’ power is running low and they need to be replaced, the electronic functions may not work properly or at all. Disconnect the tool from air source. Remove screw and battery compartment cover. Insert two (2) new batteries in the proper orientation. Do not mix old and new batteries. Close cover. Replace screw.

Assembly Procedure For Seals

When repairing a nailer, the internal parts must be cleaned and lubricated. Parker O- lube or equivalent must be used on all o-rings. Each o-ring must be coated with O-lube before assembling. A small amount of oil must be used on all moving surfaces and pivots. After reassembling, a few drops of 30W non-detergent oil or equivalent, must be added through the air line one time before normal operational use.
