7. Maintenance and Repair
General Maintenance
A good maintenance program involves thorough general housekeeping, adequate periodic re-lubrication
and replacement of worn or damaged components.
Periodic Inspection
At regularly scheduled intervals, while observing all safety precautions, observe the sample as it operates.
Inspect for:
1. Loose or missing hardware
2. Adequate lubricant in lubricator
3. Structural damage
4. Rust or corrosion
5. Damaged wiring, including exposed conductors and connections
6. Damaged airlines or pneumatic components
7. Make sure that all guards are in place and that all warning labels are in place and legible.
, GENERAL SAFETY INFORMATION, explains the purpose and intended location of the
warning signs. Warning signs are an important part of any safety program, replace any missing signs
IMMEDIATELY.
Lubrication
Airline Lubricator
An airline lubricator is not required. The cylinder is of a non-lube design requiring NO lubrication. If the use
of a lubricator is desired, it must be field mounted between the F/R and the directional control valve. If a
lubricator has been added to the system, the user must determine the appropriate lubricant and the proper
intervals for refilling the reservoir. Refer to the manufacturer's technical literature. Note that by introducing
oil into the airline, it will be discharged into the surrounding environment near the air exhausts of the
directional control valve(s) on the sampler.
Failure to observe all safety rules, written and implied and those suggested by
common sense, can result in death, serious injury and/or equipment damage.
Lock out power before performing any maintenance.
