®
Maximum Air-powered Angle Die Grinder features a non-slip, ergonomic soft-grip for greater opera-
tor comfort and fatigue reduction. Its double-bearing spindle gives it excellent concentricity and minimal vibration. A
swivel rear-exhaust enables the user to direct exhaust air and the accompanying dust away from him or herself.
Compatible Compressor & Air Tool - Guidelines for Proper Usage & Operation
Always ensure the use of appropriately matched air tools and compressors. Be sure that the air compressor being
used can supply the appropriate volume, pressure and delivery rate of air to the tool(s) without running continuously.
Using tools or combinations of tools that together or separately require more than the air compressor can deliver will
reduce performance and could void the compressor or tool guarantee/warranty.
Air System
1. Always use clean, dry and regulated, compressed air at a working pressure of between 75 and 90 PSI (between
5.2 and 6.3 Bar).
2. Never exceed the maximum pressure of 90 PSI (6.3 Bar). Operating the tool with excessive pressure could cause
personal injury, and may result in excessive noise and damage to the tool.
3. Keep hands and other parts of the body away from the tool's discharge and working areas when connecting the
air supply.
4. It is recommended that a filter-regulator-lubricator be used, and that it be located as close to the tool as possible
(see Fig. 4).
5. If a filter-regulator-lubricator is not installed, place up to 6 drops of compressor oil into the NPT inlet plug before
each use.
6. If a filter-regulator-lubricator is installed, keep the air filter clean. A dirty filter will reduce the air pressure to the
tool, which will cause a reduction in power, efficiency, and general performance.
7. For optimal performance, install a quick connector to the tool and a quick coupler on the hose, if applicable.
8. Verify that all of the connections in the air supply system are sealed in order to prevent air from leaking.
