IMPORTANT SAFETY INSTRUCTIONS
INFLATOR USE AND CARE
1. Check hoses for weak or worn condition before each use, making certain all connections are
secure. Do not use if defect is found. Purchase a new hose or notify an authorized service
center for examination or repair.
2. Release all pressures within the system slowly. Dust and debris may be harmful.
3. Do not use inflator if switch does not turn it on or off. An inflator that cannot be controlled with
theswitch is dangerous and must be repaired.
4. Place the switch off position before making any adjustments, changing accessories, or
storing the inflator. Such preventive safety measures reduce the risk of starting the inflator
accidentally.
5. Store idle inflators out of reach of children and other untrained persons. Inflators are dangerous
in the hands of untrained users.

that may affect the inflator’s operation. If damaged, have the inflator serviced before using. Many
accidents are caused by poorly maintained tools.
7. Use only accessories that are recommended by the manufacturer for your model. Accessories
that may be suitable for one inflator may create a risk of injury when used on another inflator.
8. Keep the inflator and its handle dry, clean and free from oil and grease. Always use a clean cloth
when cleaning. Never use brake fluids, gasoline, petroleum- based products, or any strong solvents
to clean your inflator. Following this rule will reduce the risk of loss of control and deterioration of the
enclosure plastic.
9. Never point any inflator toward yourself or others.
10. Keep the exterior of the inflator dry, clean, and free from oil and grease. Always use a clean cloth
when cleaning. Never use brake fluids, gasoline, petroleum- based products, or any strong solvents
to clean the unit. Following this rule will reduce the risk of deterioration of the enclosure plastic.
