OPERATION
NOTICE:
If the grinder is held in one spot too long, it will gouge and cut grooves in the workpiece. If the grinder is held at too sharp an angle, it will also gouge the workpiece because of concentration of pressure on a small area.
Use just enough pressure to keep the grinder from chattering or bouncing.
NOTE: Heavy pressure will decrease the grinder’s speed and put a strain on the motor. Normally the weight of the tool alone is adequate for most grinding jobs. Use light pressure when grinding jagged edges or loose bolts where there is the potential for the grinder to snag on the metal edge.
Lift the grinder away from the workpiece before turning off the grinder.
MAINTENANCE
WARNING:
When servicing, use only identical replacement parts. Use of any other part could create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to comply with ANSI Z87.1, along with hearing protection. Failure to do so could result in objects being thrown into your eyes and other possible serious injuries.
WARNING:
To avoid serious personal injury, always remove the battery pack from the tool when cleaning, performing any maintenance, or when storing the tool.
