Maintenance; Lubrication - Husky H4490 Use And Care Manual

Maintenance

Ensure the air line is shut-off and drained of air before removing this tool for
service or changing sockets. This will prevent the tool from operating if the throttle
is accidentally engaged.

LUBRICATION

□ An in-line filter-regulator-lubricator is recommended as it increases tool life and
keeps the tool in sustained operation.
□ Regularly check and fill the in-line lubricator with air tool oil. Avoid using
excessive amounts of oil.
□ Adjust the in-line lubricator by placing a sheet of paper next to the tool's
exhaust ports and holding the throttle open approximately 30 seconds. The
lubricator is properly set when a light stain of oil collects on the paper.
□ If it is necessary to store the tool for an extended period of time (overnight,
weekend, etc.), generously lubricate the tool through the air inlet. Run the tool
for approximately 30 seconds to ensure the oil is evenly distributed throughout
the tool. Store the tool in a clean and dry environment.
□ Recommended lubricants: Air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting
agents, and an EP (extreme pressure) additive.
