Hot melt adhesive hand applicator

摘要

An applicator gun (10) for dispensing hot melt adhesive comprises a hydraulic material supply hose connection (78), an electrical power cable connection (26), and a hanger bracket (34) connection. The hose connection may be inverted, and the power cable and hanger bracket connections interchanged so as to provide the applicator gun with different orientation capabilities. The gun also comprises a trigger lock mechanism (146) comprising detent members which provide the operator with tactile indications of the trigger lock mechanism being disposed at LOCKED and UNLOCKED positions, and an enclosed weep hole or window (204) is provided within a side portion of the gun housing so as to alert the operator to hydraulic material leakage prior to the leaking hydraulic material fouling component parts of the gun.
