ADJUSTING FOR HARDWOOD THICKNESS
ADJUSTING ROLLER BASE
The P250AA pneumatic tool is fitted with a fully adjustable
plastic base designed to prevent contact with the top edge
of the flooring. It is important to adjust the tool to fit the
flooring prior any installation. It also features a resting
block which prevent damage to the top edge of the
flooring by positioning the tool against the tongue,
preventing the gate/foot assembly from contacting the
board.
Step 1: adjusting the base for flooring thickness:
• Using the supplied Allen wrench, loosen but do not
remove screws (A); two on each side of the tool.
• With the tool in an upside down position, place a short
piece of flooring against the gate/foot assembly.
• Engage the Allen wrench in knob (B) as shown; rotate
to move the base up or down. Note that knob (B) has
a rotation range of only about 1/2 turn. Do not apply
force when a limit is reached.
• Adjust the height of the plastic base to obtain a small
gap between the gate/foot assembly and the top side
of the tongue of the sample board. A gap of 1/32"
should be adequate for most situations.
• Tighten both screws (A).
Step 2: adjusting the resting block for the width of the
tongue:
• Using the Allen wrench, loosen by about 1/2 turn ― do
not remove the two screws (C).
• With the short piece of flooring still against the
gate/foot assembly, adjust the gap between the resting
block and the tongue with screw (D). A small gap of
1/32" should be adequate for most situations.
• Tighten both screws (C).
• Ensure that screw (D) is slightly tighten. Do not apply
force on screw (D) once screws (C) are tighten.
After completing the adjustment procedure, proceed with
the installation of few boards. Carefully check for the
proper positioning of the fastener onto the board. Check
again after few more rows to insure that all parts are
secured in place. Tool may lose adjustment over time if
this procedure is not strictly followed.
The P250A can be mounted on a roller base (standard on
P250AR & P250AG).
Step 1: adjusting the back rollers for flooring thickness:
• Using the 3/16" wrench, unfasten but do not remove
screws (A), on each side.
• Put the tool upside down and position a short piece of
flooring against the gate/foot assembly.
• Engage the 3/16" wrench in knob (B) as shown; rotate
to move the base up or down. Note that the rotation
range is only about 1/2 turn, do not apply unnecessary
force when a limit is reached.
• Adjust the height of the base to obtain a small gap
between the gate/foot assembly and the top side of the
tongue of the sample board. A gap of 1/32", about half
the thickness of the nail, should be adequate for most
situations.
• Tighten both screws (A).
Step 2: adjusting the resting block for the width of the
tongue:
• The front rollers are always in contact with the front
edge of the board. It is necessary to adjust the resting
block to maintain a small gap between it and the tongue
of the board.
• Using the 3/16" wrench, unfasten by about 1/2 turn ―
do not remove the two screws (C).
• With the short piece of flooring still against the gate/foot
assembly, adjust the gap between the resting block and
the tongue. A small gap of 1/32", about half the
thickness of the nail, should be adequate for most
situations.
• Tighten both screws (C).
Before starting an installation, fasten down few
boards to ascertain that the tool is properly
adjusted. Always complu with all manufacturers
recommendations.
CONNECTION & AIR SUPPLY
LOADING THE TOOL
This tool requires clean & dry air. The use of a filter and
a pressure regulator is recommended.
Use a detachable male coupler with 3/8" NPT male
treads. The use of a 3/8" (1 cm) diameter air supply hose
is recommended. A smaller hose or a hose longer than
50' (15 m) could cause a pressure drop when the tool is
activated repeatedly.
Always use a free-flow connection for the
compressed air supply to prevent that the tool
stays charged after disconnecting the air
supply hose.
Unload tool before connecting air to prevent
accidental discharge.
To prevent injury or accidental damage to the
finished surface of the installed floor, rest the
tool onto the subflooring when connecting air,
moving tool to a different work area, loading the
tool or performing any maintenance to the tool.
Dirt, dust, and other particles in the air supply can cause
sluggish operation or premature wear. Drain water from
the compressor tank regularly. The compressor start-stop
limits should be set to deliver an air pressure of at least
100 psi (7 bar) at all times. Consult the compressor
manual or dealer for instructions on how to make this
adjustment.
At 80 psi (5.5 bar) and 40 hits per minute, this tool
consumes approximately 1.9 cu.ft (50 ) of air per minute
at 70F (21C). Higher air pressure will increase the
consumption of compressed air.
This tool is designed to be operated with a compressed
air pressure of 80 to 100 psi (5.5-7.0 bar). Air pressure of
90 psi (6.2 bar) is adequate for most situations, although
occasionally, a higher pressure could be necessary.
Never not use a compressed air pressure higher than
110 psi (7.6 bar).
PREVENTIVE MAINTENANCE
This tool requires minimal lubrication. Use only
detergent-free oil such as Primatech P-090.
Few drops of oil weekly in the air inlet is
sufficient. Other types of lubricant may degrade
the seals.
Check periodically to make sure that the head assembly
is fully screwed onto the main body. A loosen head will
damage the threads.
This tool comes in one of 3 different configurations:
• L-type 16GA nails in lengths of 1½" (38 mm), 1¾"
(45 mm) or 2" (50 mm)
• T-type 16GA nails in lengths of 1½" (38 mm) or 2" (50
mm)
• ½" crown 15½G A staples in lengths of 1½" (38 mm),
1¾" (45 mm) or 2" (50 mm)
Use only the type of fasteners identified on the
magazine. The use of any other type of
fasteners will damage the tool.
