ASSEMBLY
1. Thread the Side Handle (24) into the side of the Gear Housing (20) until tight.
2. Place Grinding Wheel (34) onto lower Disc Spacer (33) making sure depressed
center is down.
3. Thread upper Disc Spacer (33) onto Mandrel (28) and hand tighten.
4. Place Mandrel Wrench (35) on Mandrel (28) and Spacer Wrench (36) on upper
Disc Spacer (33) and firmly tighten.
SETUP
1. Designate a clean and well-lit work area. Work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the air hose along a safe path to reach the work area without creating a tripping
hazard or exposing the air hose to possible damage. Make sure air hose is long
enough to reach work area with enough slack to allow free movement while working.
3. Secure loose work pieces using a vise or clamps to prevent movement while working.
4. Make sure there are no hazardous objects (such as utility lines or foreign objects)
nearby that will present a hazard while working.
5. If an automatic oiler is not used, put a few drops of Pneumatic Tool Oil into tool at air
inlet connection before use. Add a few drops more after each hour of continual use.
6. Set the compressor to 90 PSI.
OPERATION
1. Attach grinding wheel as indicated in Assembly.
2. Grip the tool with both hands and place onto the area to grind.
3. Squeeze the trigger. You can vary the speed of the tool to suit your needs by
varying the amount of pressure applied.
4. Move the tool in a uniform pattern, either up or down or side to side to ensure
even grinding.
5. Periodically check the tool for any potential wear. Replace used grinding wheel
when necessary.
6. If the tool requires more force to accomplish the task, verify that the tool receives
sufficient, unobstructed airflow (CFM) and increase the pressure (PSI) output of
the regulator up to the maximum air pressure rating of this tool.
cAutIoN! To prevent tool and accessory failure, resulting in injury: Do not
exceed tools maximum air pressure rating.
7. If the tool still does not have sufficient force at maximum pressure and sufficient
airflow, a larger tool may be required.
8. To prevent accidents, turn off the tool, detach the air supply, safely discharge air
pressure, and release the trigger. Clean external surfaces of the tool with clean,
dry cloth, and apply a thin coat of tool oil. Then store the tool indoors out of chil-
dren's reach.
