OPERATION
Unload tool and rest it onto the subflooring, Connect
the hose and cycle tool once or twice without fasteners.
After loading the tool, the P145 nailer/stapler is ready
for use.
Use only the hammer supplied with the tool. The use of
other type of hammers may affect performance. The
rubber face of the hammer can be used with care to
help position the boards.
With the flooring firmly in place, position the tool onto
the flooring and apply downward pressure to ensure
proper seating of the fastener. Strike the head cap with
the hammer to activate the tool,
Use only the
RUBBER
FACE
of the hammer to activate the tool. Using the
steel end will damage the tool and void the
warranty.
If wood is slightly twisted, hitting the tool with
more force will assist in pulling the board up snugly.
NEVER
strike the head cap when the tool is not sitting
on the working surface.
Before starting an installation, fasten down
few boards to ascertain that the tool is
properly adjusted. Always comply with all
manufacturers recommendations.
DISASSEMBLING THE TOOL
All pneumatic components can be easily accessed with
the use of an Allen key. This section describes how to
disassemble the tool to access its internal components.
To access valve and piston assemblies:
• Remove the 4 screws and take off the head.
• Pull out the valve assembly. Inspect wear ring &
lubricate. Do not attempt to disassemble the valve
assembly.
• Pull out the piston assembly. Inspect wear ring and
lubricate.
It is usually not necessary to pull-out the bumper for
maintenance. To replace the bumper:
• Remove the 4 screws and take off the base/magazine
assembly.
• Pull out and replace the bumper.
MAINTENANCE & REPAIR
Most maintenance to the tool can be made with the
5 mm Allen wrench supplied with the tool.
Disassembly of the tool must be done in a clean
environment. Some parts can be easily damaged if
disassembled with improper tools or by inadequate
methods. Maintenance should only be performed by
trained personnel. Use only genuine Primatech
replacement parts.
To prevent injury, ALWAYS disconnect the
air supply hose when servicing or
disassembling the tool.
When servicing the tool, do not twist or force any parts.
Damage may result from such abuse. Contact your
Primatech distributor for more information.
When opening the tool for maintenance, always clean
all components of dirt, grit, or particles. Inspect the tool
carefully for broken parts or excessive wear, and
replace if necessary. When ordering parts, be sure to
specify the right part number, as well as the tool serial
number.
After any maintenance to the tool, REMOVE
ALL Fasteners before connecting air and
actuate the tool repeatedly over a piece of
wood or subflooring to insure proper
operation.
CLEANING THE VALVE
If the tool becomes sluggish or does not set the
fastener correctly, it may indicate excessive dirt, dust,
other particles, or even water, in the tool. The first step
in troubleshooting is to clean up the head assembly.
• Disassemble the head assembly as described in
previous section.
• Perform a visual inspection of the valve assembly.
Ensure that the actuator is sliding easily. Clean and
lubricate lightly. Do not attempt to take apart the
actuator assembly.
• Clean the inside wall of the head and lubricate lightly
with a non-detergent oil. Insert the valve assembly
into the head and ensure that it is sliding easily.
• Ensure the piston assembly is sliding easily into the
cylinder. It should offer some resistance, but if it
moves too easily, it may be required to replace the
piston wear-ring.
