Before Use

• Approved eye protection should always be worn by the operator and

others in the work area

• Always disconnect the air supply before making adjustments, servicing

the tool or clearing jams, and when the tool is not in use

• Never place a hand or any other part of the body in the staple discharge

area at the tool while air supply is connected

• Do not use oxygen or combustible gases as a power source for this tool

• Ear protection may be required in some environments

Safety Instructions

Warning: To avoid severe personal injury or property damage before

using the tool, read carefully and understand the following

safety instructions:

1. Wear safety glasses or goggles. The user and/or employer must ensure

that proper eye protection is worn at all times. Eye protection

equipment must conform to the ANSI or CSA requirements, and

provide both frontal and side protection. Note: non-side shielded

spectacles and face shields alone do not provide adequate protection.

2. Ear protection may be required in some environments. As the working

condition may include exposure to high noise levels that may lead to

hearing damage, ensure that necessary hearing protection is used by the

operator and others in the work area.

3. Do not use any air source beside an air compressor. The tool is

designed to operate on compressed air. Do not operate the tool on any

other high pressure gas, combustible gases (such as oxygen or

acetylene) since there is risk of explosion.

4. Do not operate the tool near a flammable substance.

5. Do not use the wrong fitting. 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 be able to

drive a fastener even after the air line is disconnected, possibly causing

injury.

8095903manual 11/4/05 3:06 PM Page 2

6. Disconnect the air supply and empty the magazine when the tool is not

in use. Also when moving to a different work area, adjusting,

disassembling or repairing the tool, and when clearing a jammed

fastener.

7. Inspect screw tightness. Loose or improperly installed screws or bolts

cause accidents and tool damage when the tool is put into operation.

Inspect to confirm that all screws and bolts are tight and properly

installed prior to operating the tool.

8. Do not touch the trigger unless you intend to drive a fastener.

Whenever the air supply is connected to the tool, never touch the

trigger unless you intend to drive a fastener into the work. It is

dangerous to walk around carrying the tool with the trigger pulled, and

this and similar actions should be avoided.

9. Never point the nosepiece toward people as serious accidents may be

caused when misfiring. Be sure the nosepiece is not pointed toward

people when connecting and disconnecting the hose, loading the

fasteners, or during similar operations.

10. Use specified fasteners. The use of fasteners other than specified will

cause tool malfunction. Be sure to use only specified fasteners when

operating the tool.

11. Press the nosepiece to the work properly. Failure to do so can result in

a fastener flying up and is extremely dangerous.

12. Keep hands and body away from the nosepiece. When loading and

using the tool, never place a hand or any part of the body in the

fastener discharge area of the tool. It is very dangerous to hit the

hands or body by mistake.

13. Do not drive fasteners on the top of other fasteners, a fastener could

be deflected, causing injury.

14. Remove fasteners after completing operation. If fasteners are left in

the magazine after operation, there is a danger of a serious accident

occurring prior to the resumption of operation, should the tool be

handled carelessly or when connecting the air fitting. For this reason,

always remove all fasteners remaining in the magazine.

15. Check operation of the contact trip mechanism frequently when using

a contact trip type tool. Do not use the tool if the trip is not working

correctly, as accidental driving of a fastener may result. Do not

interfere with the proper operation of the contact trip mechanism.

8095903manual 11/4/05 3:06 PM Page 3

16. When using the tool outside or on elevated locations such as roofs,

start fastening at the lower part and gradually work your way up.

Fastening backward is dangerous as you may loose your footing.

Secure the hose at a point close to the area you will be working.

Accidents may be caused due to the hose being pulled inadvertently

or getting caught.

17. Never use a tool that is defective or a performs abnormally. Never

actuate the tool into free space. This will avoid any hazard caused by

free flying fasteners and excessive strain on the tool.

Additional Precautions

• Do not use the tool as a hammer

• Always carry the tool by the handle, never carry the tool by the air hose

• The tool must be used only for the purpose it was designed

• Never clamp the trigger in locked operation position

• Keep the tool in a dry place out of reach of children when not in use

• Do not use the tool without safety warning label

• Do not modify the tool from original design or function without

approval by the manufacturer

Air supply and connections

1. Do not use any power source except an air compressor. The nailer is

designed to operate on compressed air. Do not operate the nailer on any

other high pressure gas, or combustible gases such as oxygen or

acetylene, since there is the danger of an explosion. For this reason,

absolutely do not use anything other than an air compressor to operate

the nailer.

2. Operate within the proper air pressure range. The nailer is designed to

operate within an air pressure range of 70 to 120 PSI. The pressure

should be adjusted to the type of work being nailed. The nailer should

never be operated when the operating pressure exceeds 120 PSI.

3. Do not operate the tool near a flammable substance such as gasoline or

paint thinners. Volatile fumes from these substances could be drawn

into the compressor and be compressed together with the air, resulting

in an explosion.

4. Do not use the wrong fittings. 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.

5. Disconnect the air chuck when the tool is not in use. Always

disconnect when operation has been completed or suspended, when

moving to a different work area, adjusting, disassembling or repairing

the nailer, and when clearing a jammed nail.

8095903manual 11/4/05 3:06 PM Page 5

Fittings: Install a male plug on the tool

which is free flowing and which

will release air pressure from the

tool when disconnected from the

supply hose.

Hoses: Hose with a 1/4" I.D. should have

a max length of 15 ft. For lengths

over 15 ft, use 3/8" I.D. hose. 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 the tool.

Filter, regulator, lubricator (F.R.L.): (Inline air filter, regulator, oiler)

Refer to tool specifications for

setting the correct operating

pressure for the tool.

Note: a filter will help to get the best performance and minimum wear

from the tool because dirt and water in the air supply are major

causes of wear in the tool. Frequent, but not excessive, lubrication

is required for the best performance. Oil added through the air line

connection will lubricate the internal parts.

Operating Instructions

Eye protection is required to guard against flying fasteners and debris,

which could cause severe eye injury. The user must ensure that proper eye

protection is worn., Eye protection equipment must conform to national

safety standards and provide both frontal and side impact protection.

NOTE: non-side shield spectacles and face shield alone do not provide

adequate protection.

Warning: always disconnect the air supply from the tool when operation

has been completed or suspended, when moving to a different

work area, adjusting, disassembling, or repairing the tool, and

when clearing a jammed fastener.

F.R.L.

Nail loading

1. Open the magazine. Pull down the door latch and

swing door open. Swing magazine cover open.

2. Check adjustment. The nail support can be

moved up and down to three settings. To change

setting, pull up on the post and twist to the

correct step. The nail support should be adjusted

correctly to the position as follows.

3. Load the coil of nails. Place a coil of nails over

the post in the magazine. Uncoil enough nails to

reach the feed pawl, and place the second nail

between the teeth on the feed pawl. The nail

heads fit in the slot of nose.

• 1-3/4" nails – use bottom step

• 1-1/4", 1-1/2" – use middle step

• 7/8", 1" – use top step

4. Swing cover closed.

5. Close the door. Check that latch engages (if it

does not, ensure that the nail heads are in the slot

on the nose.)

Driving depth adjustment dial.

Warning: Always disconnect air supply before adjusting the dial.

1. With air pressure set, drive nails into a representative material sample

to determine if adjustment is necessary.

2. If adjustment is required, disconnect air supply.

3. Refer to the mark on the contact arm cover for direction to turn the

adjustment dial.

4. Reconnect air supply.

Shingle Gauge

Warning: Always disconnect the air supply before making an adjustment.

1. This gauge can be used to control shingle spacing. Loosen two screws

to adjust gauge to desired shingle exposure, as shown.

8095903manual 11/4/05 3:06 PM Page 7

Driving Fasteners

Contact fire operation (bump fire):

For contact fire operation, hold the trigger and depress the contact arm

against the work surface.

Procedure: A. Hold the trigger. B Depress the contact arm.

Warning: The operator must not hold the trigger pulled on contact trip

tools except during fastening operation, as serious injury could

result if the trip accidentally contacted someone or something

causing the tool to cycle.

Warning: Keep hands and body away from the discharge area of the tool.

Operator note: Do not press the tool against the work surface with

excessive force. Instead, allow the tool to recoil off the

work surface to avoid a second unwanted fastener.

Maintanence

Warning: Do not use gasoline or similar highly flammable liquids to

clean the nailer. Vapour could be ignited by a spark causing an

explosion. Tar and dirt may build up on the nose and trip lever.

This can prevent correct operation. Remove any buildup with

kerosene #3 fuel or diesel fuel. Do not immerse the nailer into

these solvents beyond the height of the nail heads, to avoid

getting the solvent into the drive cylinder. Dry off the nailer

before use. Any oil film left after cleanup will accelerate the

tar build-up, and the nailer will require more frequent re-

cleaning.

Note: Solvents sprayed on the nose to clean and free up the trip may have

the opposite effect. The solvent may soften the tar on the shingles

and cause tar build-up to be accelerated. Dry operation is better, as

noted above.

Note: Do not fire the nailer when it is empty.

8095903manual 11/4/05 3:06 PM Page 8

1. Use an F.R.L. Failure to use an F.R.L. allows the moisture and dirt

inside compressor to pass into the nailer directly. This causes rust and

wear and results in a poor operating performance. The hose length

between F.R.L. and nailer should be no longer than 16-1/2 ft since a

longer length results in a reduction in air pressure.

2. Use recommended oil. Only air tool oil should be used to lubricate the

nailer. Upon completion of operation, place 2 or 3 drops of oil in the

air plug with the jet oiler.

3. It is important that the nailer be properly lubricated. Without proper

lubrication, the nailer will not work properly and parts will wear

prematurely.

4. Inspect and maintain daily or before each operation.

Warning: Disconnect air supply and empty the magazine when

inspecting or maintaining the tool.

• Drain air line filter and compressor

• Keep lubricator filled in F.R.L.

• Clean filter element of F.R.L.

• Tighten all screws

• Keep contact arm moving smoothly

Storage

• When not in use for an extended period, apply a thin coat of the

lubricant to the steel parts to avoid rust.

• Do not store the tool in a cold weather environment. Keep the tool in a

warm area.

• When not in use the tool should be stored in a warm and dry place.

Keep out of reach of children.

• All quality tools will eventually require servicing or replacement of

parts because of wear from normal use.

Troubleshooting / Repairs

The trouble shooting and/or repairs shall be carried out only by the

distributors or by other specialists.
