6.0 MAINTENANCE
This tool has been designed to require a minimum amount of attention by the operator. However, some
guidelines should be followed to obtain top performance and a long, useful life.
This tool is capable of fairly high rpm, but it is recommended that a valve be installed in the airline to
regulate the top speed. For many applications lower rpm may improve performance. It will definitely be
easier on the motor and swivel.
6.1 AIR MOTOR
1. The air supply should be filtered and use a line oiler to supply lubrication.
2. For added protection when preparing to store the tools, pour a few ounces of oil or diesel directly into
the port and run briefly.
3. Keep the control handle clean and working properly.
4. Always blow out the airline before connecting hardware.
Repairs to the air drill are straight forward and require only standard metric wrenches. The most common
problems are worn and sticking vanes. Clean all components and lubricate thoroughly before
reassembling.
Refer to the appendix for more detailed information.
6.2 WATER SWIVEL
1. Grease the bearings regularly. Every few hours of operation inject enough to cause some grease to
push out past the retainer washer.
2. Periodically check the shaft collar and end nuts to be sure they are tight. Any looseness may cause a
premature seal or bearing failure.
3. The high pressure seals may leak occasionally but heal themselves during continued use. The seals
do not fail abruptly and can be used for several hours even after continuous leaking begins. As long as
the leak is tolerable the swivel can be operated without fear of damaging it.
4. Keep all connections clean and flush out the supply hoses before connecting to the swivel.
