WARNING

Some dust created by power sanding, sawing, grind­ing, drilling, and other construction activities contains
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement, and
other masonry products.

• Arsenic and chromium from chemically treated
lumber.

Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to fil­ter out microscopic particles.

I. INTRODUCTION II. COMMENTARY

The G3690 Angle Finish Nailer is designed for
driving and setting clipped head finish nails in
most natural and composite wood materials. It
is especially suited for cabinetmaking and fas­tening trim moldings. The tough, lightweight
construction offers dependable performance
while reducing operator fatigue.

This nail gun is a part of our complete line of
nail guns covering most applications. It will
shoot a variety of finish nails up to 2

1

/2" long.
The ability to shoot longer nails makes it ideal
for trim applications when applying moldings
over sheet rock and fastening thicker mold­ings to other trim.

III. SAFETY RULES FOR NAIL GUNS

1. NEVER leave the gun connected to an air

source when inspecting or maintaining.

2. The gun must be routinely inspected for

worn or damaged parts and air leaks. If
the gun is faulty, it should be removed

from service and labeled, “DO NOT

USE.”

3. Make sure the safety nose is functioning

properly before loading fasteners and the
magazine spring is set before operating.

4. DISCONNECT the gun from the air

source before loading fasteners.

5. ALWAYS point gun away from yourself

and others when loading or operating.

6. DISCONNECT gun from the air source if

gun jams or when performing other main­tenance inspections.

7. DO NOT connect gun to the air hose until

you are in position and ready to operate
the gun safely.

8. BE AWARE of others in your work area.
NEVER shoot the gun if others are in

your line of fire.

9. KEEP HANDS AND OTHER BODY
PARTS AWAY FROM THE GUN TIP AT
ALL TIMES.

10. NEVER manually depress the safety

nose and shoot fasteners for any reason.

11. NEVER leave a pressurized gun unat-

tended, especially when children are pre­sent. Disconnect gun from the air source,
remove fasteners, and put the gun out of
reach.

12. DO NOT rest a pressurized gun against

your body for any reason.

13. DO NOT carry gun with your finger on the

trigger. Gun will fire if safety nose is acci-

dentally depressed.

14. DO NOT place your free hand or feet

near the gun tip to support the work. If
you cannot safely support the work with­out placing body parts near the gun tip,
do not use this gun.

15. DO NOT operate the gun if workpiece is

between you or someone else and the
gun. Reposition yourself so you and oth­ers are behind the gun.

16. ALWAYS wear ANSI approved personal

protective equipment for your eyes and
ears while operating this tool. Others
near your work area must also wear eye
protection.

17. All air tools exhaust compressed air. If

working in an area where dust will
become airborne due to exhausted air,

WEAR RESPIRATORY PROTECTION.

18. Use only clean, dry, regulated, com-

pressed air. DO NOT connect this air tool

to any pressurized gas other than com­pressed air.

19. Air compressors must comply with ANSI

B 19.3 - 1981 (U.S.), “Safety Standard for
Compressors for Process Industries.”

20. DO NOT operate at a pressure higher

than 120 PSI.

21. NEVER use this gun for fastening alu-

minum, brass, metal, plastics, or any
other like material.

22. Air hose must be rated as having a mini-

mum working pressure of 150 psig or
150% of the maximum pressure pro­duced in the line, whichever is greater.
Inspect air hoses frequently.

IV. UNPACKING

Carefully remove the items packed in the car­ton. It may be a good idea to save the carton
and packing material in case it might be need­ed in the future. Upon removal of all items
from the package, you should have:

1. Nail Gun

2. Allen Head Wrench

3. Oil Bottle

4. Safety Goggles

Magazine

Figure 1 shows the front side of the nail gun.

Figure 2 shows the back side of the nail gun.

A. AIR PRESSURE

Air pressure should be set at the minimum
required to set the fastener and must not
exceed 120 p.s.i. Follow all safety items

above and see Section V.B. Consistently

operating at unnecessarily high pressures will
put excessive stress on internal parts which
will lead to premature gun failure.

B. AIR QUALITY

This air gun must be regularly oiled and oper­ated with treated or clean air. It is a precision
tool with close internal tolerances designed for
repetitious use. Wet and dirty air will negative­ly affect the gun’s performance as well as pre­maturely destroy internal parts.

To ensure that the best quality air enters
your nail gun:

1. Use an in-line system to automatically oil,

filter, and dry compressed air. Grizzly
offers an in-line regulator / filter / water­separator / lubricator (G2304). Please
refer to our catalog for price and ordering
information.

2. The intake air filter on your compressor

must be clean and operational.
Periodically clean or replace this filter. It
is your primary line of defense.

3. Drain the compressor air storage tank(s)

often. If conditions are humid, drain up to
several times daily. Water vapor will con­dense and accumulate in the bottom of
the storage tank(s). The internal metal
parts of the nail gun will be corroded by
the moisture that is passed through the
air supply hose.

4. Keep air hoses as clean as possible inter-

nally. Inspect nipples and couplers for
any dirt and moisture. Blow out prior to
connecting the gun.
