Dispense Force Control
The tool is designed to dispense a wide range of adhesives and caulk. In certain cases, the

like. To reduce the risk of damaging the tube or casing, always follow the recommendations of
the caulk/adhesive manufacturer.

maximum speed.
Turn the dial to any position between “1” for the
lowest speed and “6” for the highest speed.

• Never change the maximum speed while the tool
is running. Failure to obey this warning could
cause a loss of control of the tool and result in
