CONNECTION & AIR SUPPLY
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 1.5 cu.ft (44
) of air per minute
at 70
F (21
C). 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
80 psi (5.5 bar) is adequate for most situations, although
occasionally, a higher pressure could be necessary.
Never not use a compressed air pressure higher than
100 psi (7.0 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.
LOADING THE TOOL
This tool comes in one of 2 different configurations:
• nailer Q550AL using standard L-type 18
GA
nails in
lengths of 1¼" (32 mm), 1½" (38 mm) and 1¾"
(45 mm)
• combo nailer/stapler Q550AC using either standard
L-type 18
GA
nails in lengths of 1¼" (32 mm), 1½"
(38 mm) and 1¾" (45 mm) or ¼"-crown 18
GA
staples
in lengths of 1" (25mm), 1¼" (32 mm) and 1½" (38 mm)
To load the tool:
• Insert a strip of either 18
GA
nails or staples into the
magazine.
• Pull back the pusher until it engages behind the strip.
• To remove fasteners from the magazine, simply
squeeze the pusher with your thumb and finger and
allow the spring to recoil slowly.
Use only the type of fasteners identified on the
magazine. The use of any other type of
fasteners will damage the tool.
