Tactical Training Systems' training facilities require minimum maintenance on a regular basis. For routine upkeep, an inspection schedule must be developed and conducted regularly. The frequency of these inspections will vary depending on the training schedule and the severity of the scenarios.
Clean and Lubricate
For belt replacement, loosen the tensioning device far enough to allow removal of the belt by hand. Do not force belts on or off. This may cause cords to break, leading to premature belt failure. Once installed, adjust belts as shown in the "Pre-Starting Checks" section of the installation manual.
Shaft bearings are classified into two groups: relubricating and non-relubricating. All bearings on standard Model CWB fans are factory lubricated and require no further lubrication under normal use (between -20°F and 180°F in a relatively clean environment). Units installed in hot, humid or dirty locations should be equipped with special bearings. These bearings will require frequent lubrication. Use caution to prevent over-packing or contamination. Grease fittings should be wiped clean. The unit should be in operation while lubricating. Extreme care should be used around moving parts. Grease should be pumped in very slowly until a slight bead forms around the seal. A high grade lithium base grease is recommended.
Motor maintenance is generally limited to cleaning and lubrication (where applicable). Cleaning should be limited to exterior surfaces only. Removing dust build-up on motor housing ensures proper motor cooling. Greasing of motors is only needed when fittings are provided. Many fractional motors are permanently lubricated and should not be lubricated further. Motors supplied with grease fittings should be greased in accordance with manufacturers' recommendations. Where motor temperatures do not exceed 104°F (40°C), the grease should be replaced after 2,000 hours of running time.
Wheels require very little attention when moving clean air. Occasionally, oil and dust may accumulate causing imbalance. When this occurs, the wheel and housing should be cleaned to ensure smooth and safe operation. The unit should be made non-functional when cleaning the wheel or housing (fuses removed, disconnect locked out, etc.).
All fasteners should be checked for tightness each time maintenance checks are performed prior to restarting the unit.
A proper maintenance schedule program will ensure dependable service for years to come.
