are as shown in the diagram. Hands must never be
placed in front of the tool muzzle or nose piece. In the
event of an accidental discharge, the piston and/or
fastener can pass through the operators hand.
5. Once the tool is in the closed
position, place it against the work
surface. Hold the tool firmly with
two hands and completely depress
the barrel. Then squeeze the
trigger. Always hold the tool perpendicular to the work
surface. Hold the tool firmly against the work surface to
avoid excessive recoil. Never depress the tool against
anything except the work surface.
In the event that the load does not discharge
after the trigger is pulled, continue to hold the tool depressed
against the work surface for at least 30 (thirty) seconds in
case of a delayed load discharge. Then carefully remove the
entire load strip and dispose of it in a can of water or other
non flammable liquid. Never attempt to force or pry a load
out of a tool chamber. Do not discard unfired loads into a
trash container.
6. To prepare for the next fastening, point the tool in a safe
direction. Snap the barrel forward as described in step 1.
This action will eject the spent powder load and properly
reset the piston. Always insert a new fastener before
loading powder load in the chamber. Do not attempt to
unload or disassemble a jammed, stuck or broken tool
as improper handling may cause it to discharge and
strike operator and/or bystander. A jammed tool must be
pointed in a safe direction at all times. Tag the tool and
lock it up. Call your D
proper assistance.

Daily Function Test

Check the functioning of the tool, without a powder load
or fastener in the tool, by pushing down against the work
surface, pulling the trigger, and releasing the tool from the
work surface. function the unloaded tool several times and
insure that the breech parts and firing mechanism operate
freely before fastening with the tool.
Your D wALT Authorized representative should be asked
E
to assist the first time you disassemble and clean your tool.
If you ever have any trouble reassembling the tool, or have
any doubt about worn parts, call your D
Powder Distributor.
Cleaning
AIl parts should be cleaned with detergent oil and the wire
brushes supplied with your tool kit. Remove heavy dirt build-
up with the brush. After cleaning with oil, all parts should be
wiped thoroughly dry. Excess oil will tend to collect dirt and
dust. wear eye protection when cleaning the tool. The piston
rod, barrel assembly, and receiver should all be cleaned of
excess dirt on a daily basis. Check the condition of the piston
for damage from wear and deformation.
To maintain this tool in good working condition, it is
necessary to disas semble and clean the entire tool if dirt

is evident in the breech face, or if the tool appears to lose
power. All parts should be cleaned with oil and wire brushes.
Remove heavy dirt. All parts should be wiped thoroughly dry
after cleaning with oil.
General tool mainte nance should be performed at six
month intervals or more frequently as required by the
frequency of tool use.

Replacing or Repairing the Piston

The piston is an expendable part and must be replaced
periodically. Typical signs of a worn out piston are: breaking,
bending or mushrooming. Prior to
servicing the tool make sure there is no
powder load in the tool. Use caution and
do not lose or damage any tool parts.
1. Loosen the cap on the reset pin by
turning it counter clockwise. Remove the
reset pin cap.
2. Hold the barrel in place, then remove
the reset pin spring and reset pin.
3. Slide the barrel from the receiver by
pulling it forward. If excessive dirt is built
up inside the receiver, clean it with a wire
brush.
4. Unthread the nose piece from the
barrel by turning it counter clockwise.
Pull the piston forward out of the barrel.
If a vise clamp is used
to hold the barrel, protect the bar rel from
damage.
5. Clean the piston using a wire brush.
Inspect it for worn or damaged piston ring,
chipped end, or bending. Apply lubricant to
the piston shank to minimize piston sticking
from an overdrive con dition. wipe the piston
dry.
6. If a piston tip is damaged, it can be
shortened a maximum of 0.20 inches.
The tip of the piston should be grooved
flat and at 90 degrees to the shank of
the piston. The cham fer of the piston
must also be reground as shown. Piston
grinding should be performed by qualified per sonnel using
the proper equipment.
Reassembly:
7. Press the piston into the barrel.
Thread the nose piece into the barrel
and tighten it clockwise until finger tight.
be sure the nose piece is fully seated.
8. Align the slot in the barrel with the
reset pin opening in the bottom of
the receiver. Insert the barrel into the
receiver. Insert the reset pin, and reset
pin spring. Tighten the reset pin cap
clockwise until it is finger tight and fully seated.
Upon reassembly of the tool perform the following test.
Depress the tool against a flat, hard surface and pull the
trigger. The barrel assembly should slide smoothly inside the
tool receiver. The firing pin should release after the trigger has
been pulled.
