MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care
evaluating problem tools. Disconnect air supply and empty the magazine when
inspecting or maintaining the tool.
REPLACEMENT PARTS:
Use only genuine parts from the manufacturer or distributor. Do not use modified parts or parts which will not give
equivalent performance to the original equipment.
Tighten all screws.
Keep contact arm moving smoothly.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use O-Ring lubricant on all O-Rings.
Coat each O-Ring with O-Ring lubricant before assembling. Use a small amount of oil on all moving surfaces and
pivots. After reassembly add a few drops of Air Tool Lubricant through the air line fitting before testing.
AIR PRESSURE AND VOLUME:
Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersize
fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent the tool from
receiving an adequate volume of air, even though the pressure reading is high. The results will be slow operation,
misfeeds or reduced driving power. Before evaluating tool problems for these symptoms, trace the air supply from
the tool to the supply source for restrictive connectors, swivel fittings, low points containing water and anything else
that would prevent full volume flow of air to the tool.
DRIVER MAINTENANCE INSTRUCTIONS
Worn driver causing poor quality or loss of power:
Wear or a chip on the driving tip will affect the nail drive, giving symptoms of bent and incompletely driven nails, and
damaged nail heads.
The driver length may be adjusted to allow the driving tip to be redressed to compensate for wear. Heat and precise
measurement are required. Contact a qualified service technician for this adjustment.
The length setting for a new driver is shown below. Measurement is from the bottom face of the main piston.
Note that the measurement from the top of the piston gives the maximum amount the driver may be adjusted to allow
redressing. Always extend the driver the minimum required to allow
redressing to restore the driving end; several re-
dressings will be possible before this maximum depth is reached.
When using optional flangeless driver, see adjustment below. Be sure to use proper preparation and installation.
TROUBLESHOOTING / REPAIRS
The troubleshooting and / or repairs shall be carried out only by the authorized dealer / distributor
or
by other
pneumatic tool specialists.
