Technical Specifications

Always wear approved front and side EYE PROTECTION
when operating this Nailer. Others in the work area
should also wear front and side EYE PROTECTION. Eye
protection will help guard against fl ying nails and debris,
which could cause severe eye injury.
EAR PROTECTION may be required to prevent hearing
damage when there are high noise levels in the work
area.
Always DISCONNECT THE AIR SUPPLY before making
any adjustments, repairing, clearing jams or when the
Nailer is not in use.
Never attach the female end of a quick disconnect to the
Nailer. This will trap air inside the Nailer and permit it to
be discharged. Only the unrestricted male connection
should be attached to the Nailer.
Use only regulated compressed air, do not use bottled
gases of any kind to power this Nailer. Normal air
pressure should not exceed 120 psi or damage to the
Nailer and seals may occur. Excess air pressure can
cause the Nailer to explode.
THE TRIGGER IS A SAFETY DEVICE and should only
be pulled when the Nailer is in proper position on the work
surface and before the plunger is struck with the mallet.
Do not tie or tape down the safety trigger as the Nailer
could discharge if dropped on the plunger. The Nailer will
not fi re unless the trigger is pulled before the mallet blow.
Do not use the trigger safety as a lock up for the plunger
then rack the wood using the locked up Nailer body. It will
severely damage the mechanism and the Nailer. Use the
mallet to rack the wood strip, not the Nailer.
DO NOT USE THE METAL END OF THE MALLET TO
STRIKE THE PLUNGER, use the rubber capped end
only.
Never place any part of the body in the discharge path
of the Nailer when air is connected to the Nailer. Always
make sure Nailer is empty of cleats before connecting
air hose so as to prevent any accidental discharge from
occurring.
Never leave the Nailer unattended while it is connected to
an air supply.

nails—provides several
distinct advantages. Like our Model 45, the Model 445
can nail down 1/2”, 3/4” and 33/32” tongue and groove
hardwood fl ooring through the use of easy-to-change,
no-mar adapter plates.
WARNING
Whenever air is connected to the
Nailer, keep body parts away
from the nail discharge path. Disconnect the air line
before making adjustments or repairs on the Nailer.
Only connect air to an unloaded Nailer so as to prevent
accidental discharge.
Consult the drawing for the appropriate adapter pad to
use with the thickness of fl ooring you are installing.
Rack the fl ooring into place with the rubber end of the
mallet supplied with the Nailer
Place the Nailer Adapter Foot on the tongued edge of
the fl ooring strip to be nailed. Be sure the Adapter Foot
is pressed tightly against the edge of the fl ooring strip
above the tongue.
Be sure fl ooring strips are racked tightly. Pull the Safety
Trigger and tap the Nailer Plunger Rubber Cap with the
rubber capped end of the mallet to discharge the Nailer.
WARNING
It is not necessary to hit the Nailer
hard to activate it. Never hit the Nailer with excessive
force or with the metal end of the mallet, this will damage
the Nailer.
Never use the Safety Trigger interlock to lock up the
plunger and rack the wood with blows to the Nailer body.
This will severely damage the safety mechanism and
Nailer. This abuse and damage is not covered by the
warranty.
Before each use check all screws to be sure they are
tight. Shock and vibration can loosen screws. Do not over
tighten any screw.
