MAINTENANCE
Most problems with tools are a result of:
1. Normal wear and tear to components due to high usage.
2. Lack of proper lubrication.
3. Dirt or water that may enter the tool via air lines.
4. Defective rings.
LUBRICATION
1. The C-Ring tool VA0278 is designed for long, trouble free use with minimal in-line
lubrication. (If an in-line lubricator is used, it should be set at a minimal rate of flow.)
2. When lubricating tool, Pneumatic Fastening Tool Oil, Vertex part number VC0340 is
recommended. When oiling, a couple of drops of oil should be placed through the
airline fitting. Excess oil in tool will attract dirt, lint, and the tape used to collate rings,
preventing smooth operation. Cycle tool to expel excess oil.
3. When servicing or repairing tool a high grade lithium grease, Vertex part number
VH0214 is recommended for all o-rings and moving parts.
AIR FILTER AND REGULATOR
1. The airline should always contain a filter and regulator unit to provide tool with a
constant flow of clean, dry air. Moisture and contaminates entering tool will decrease
the serviceable life of tool.
2. The regulator should be set between 70 and 90 psi (4.8 to 6.2 bar). Never operate
tool over 100 psi (6.9 bar).
TIPS ON EXTENDING TOOL LIFE
1. Always use Vertex brand fasteners and always use Vertex genuine parts when
replacing worn or broken parts. Generic fasteners, and parts may shorten tool life
and will void your tool warranty.
2. Use tool at minimum amount of air pressure needed to do the work at hand. Excess air
pressure will reduce the life of tool.
3. Keep tool clean and dry and always use clean dry air.
4. Avoid dropping tool, a primary reason for parts replacement.
Rev H 4-30-2010
HELPFUL HINTS FOR FIELD SERVICE OF TOOL JAMS
SAFETY FIRST – Always disconnect tool from air supply before attempting to clear a jam or
servicing tool.
The most common reason for jamming problems is worn parts. Common parts that see a lot of
wear are the jaws, pusher assembly and the pusher spring.
Note: refer to correct tool schematic for location of parts and correct part numbers.
TROUBLESHOOTING

Ring Defects
Vertex Fasteners Hog Ring Tools are designed to operate with rings manufactured to standard
tolerances. Defective rings can be the cause of many ring-forming problems. Never use rings
that are too loose or otherwise defective. Below are some examples of defects that can
occur.
REPAIR
Note: Mineral spirits is recommended for cleaning tool and parts. Do not allow
rubber of handle to soak in mineral spirits as this will cause the rubber to
swell over time and become loose on tool. Wipe off immediately, dry parts
thoroughly before reassembly, use adequate ventilation.
