SIOUX IW500MP-4R Instructions page 4

LUBRICATION
For maximum performance and tool life, an air line lubricator, set to deliver 4 drops per minute, is recommended. SIOUX No. 288 Air Motor Oil is
recommended.
If an airline lubrication is not used, it is recommended that the tool be oiled daily before use to improve performance. Add 4-8 drops of air motor oil and
run the tool for 10-20 seconds to distribute oil through the tool.
MAINTENANCE
Water, dust and other airline contaminants can cause rust and vane sticking. For long periods between tool use, flush the tool with 5 ml of oil and run for
10 seconds. This will help remove contaminants and reduce the formation of rust.
DISASSEMBLY:
1. Disconnect tool from air supply.
