Loading the Tool

 

TO PREVENT 

SERIOUS INJURY 

FROM ACCIDENTAL OPERATION, 

BEFORE LOADING:

• Wear ANSI‑approved safety 

goggles with side shields.  

Other 

people in the work area must also 

wear ANSI-approved impact safety 

goggles with side shields.

• Release the trigger.

• Detach the air supply.

• Attempt to fire the Tool into a 

piece of scrap wood to ensure 

that it is disconnected and is 

incapable of firing any fasteners.

1.  To open the Magazine Cover (85), pull 

up on the Latch (81) and pull back the 

Moveable Cover Plate (80).

2.  Once the Cover Plate is lifted, lift up the 

Magazine Cover.

3.  Check the Nail Support (92) inside the 

Magazine.  Twist the Support and pull 

it up (or down) to adjust to use various 

lengths of nails from 3/4” to 1-3/4”:

A. 3/4” Long Nails 

(Use top setting marked on inside of 

Magazine).

B. Between 3/4” and 1‑3/4” Long Nails 

(Use middle setting marked on inside 

of Magazine).

C. 1‑3/4” Long Nails 

(Use bottom setting marked on inside 

of Magazine).

3.  Place a coil of nails around the Nail 

Support in the Magazine.

4.  Uncoil enough nails to reach the Drive 

Guide (29).  Place the 

second

 nail on the 

coil between the tabs of the Drive Guide, 

making sure the nail head fits in the slot 

in the top end of the Drive Guide.

5.  Swing the Magazine Cover closed.  

Then, close the Cover Plate, making 

sure the Latch snaps shut.  If the Latch 

does not engage, the nail head is not in 

the slot in the upper portion of the Feed 

Drive Guide.

Roofing Gauge Adjustment

1.  The Roofing Gauge (82) controls roof 

shingle spacing.  To adjust the Roofing 

Gauge to work with a particular width of 

shingles, use the accessory Hex Wrench 

to loosen the Hex Bolt (83) on the 

Roofing Gauge.

2.  Slide the Bracket forward or backward to 

the desired shingle spacing.

3.  Then, retighten the Hex Bolt.

General Operating Instructions

1.  Test the Tool, as directed on page 10 or 

11, before each use.

2.  If an automatic oiler is not used, add 

a few drops of Pneumatic Tool Oil to 

the airline connection before use.  Add 

a few drops more after each hour of 

continual use.

3.  Attach the air hose to the Nailer.  Start 

your compressor and check the pressure 

making sure it is not set to go over the 

maximum 120 PSI.

4.  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 once.  

Do not fire 

repeatedly.  

Nails could bounce off of 

one another, damaging the workpiece or 

causing PERSONAL INJURY.
