Lock-on Button

The lock-on button offers increased comfort in extended use
applications. To lock the tool on, push the lock-off lever (C) then
depress the paddle switch/trigger switch.
With the tool running, depress the lock-on button (B). The tool will
continue to run after the paddle switch is released.
To unlock the tool, depress and release the paddle switch/trigger
switch. This will cause the tool to stop.
WARNING: Allow the tool to reach full speed before touching tool
to the work surface. Lift the tool from the work surface before turning
the tool off.

WARNING: Always observe the safety instructions and applicable
regulations.
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments
or accessories. Before reconnecting the tool, depress and
release the trigger switch to ensure that the tool is off.
Install Grinding Wheels
1. Remove mounting nut by turning it counterclockwise (when facing
outer side of accesssory). The spindle can be held stationary by
holding a wrench on the flats provided on the exposed portion of
the spindle.
2. Only tighten nut sufficiently to drive the wheel without slippage.
3. When starting the tool (with a new or replacement wheel installed)
hold the tool in a well protected area. If the wheel has an
undetected crack or flaw, it should burst in less than one minute.
Never start tool with a person in line with the wheel. This includes
the operator.
WARNING: Grasp tool firmly with both hands to maintain control
of the tool at start up and during use and until the wheel or accessory
stops rotating. Make sure the wheel has come to a complete stop
be fore laying the tool down.
Put the work in a vise or clamp it securely. Use a face mask over the
nose and mouth if the operation raises dust. Treat the wheel with
respect. Do not jam the wheel into the work or use unnecessary
pressure. Grind only on the face of the wheel (Figure 2), unless you
have a special wheel specifically make to permit grinding on the side
of the wheel.

lead without a chemical analysis, we recommend the following
precautions when sanding any paint:
