is cool enough to touch with your bare hand. Remove the filler cap
slowly in order to relieve pressure.
NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting, and repair
of the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
Refer to Special Publication, PERJ1017, "Dealer Service Tool
Catalog" for tools and supplies suitable to collect and contain fluids on

Cylinders equipped with lock valves can remain pressurized for very
long periods of time, even with the hoses removed.
Failure to relieve pressure before removing a lock valve or
disassembling a cylinder can result in personal injury or death.
Ensure all pressure is relieved before removing a lock valve or
disassembling a cylinder.
Note: Cleanliness is an important factor. Before you begin the disassembly procedure, the exterior of
the components should be thoroughly cleaned. This will help to prevent dirt from entering the internal
mechanism. Precision components can be damaged by contaminants or by dirt. Perform disassembly
procedures on a clean work surface. Keep components covered and protected at all times.
Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned in
cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint
may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn
or damaged, use new parts for replacement.
