740V-HL Dispense Gun

Introduction

The 740V-HL (#7021209) hand-operated dispense gun is a rugged industrial lever-actuated fluid dispensing valve. The
valve incorporates a quick-change fluid body for fast and easy cleaning. The fluid inlet fitting for 1/4" OD feed tubing and an
assortment of dispensing tips are included.

Getting Started

1. Install the feed tube from the fluid reservoir to the inlet
fitting and tighten the compression nut to secure. The
fluid body may be rotated up to 1/2 turn to locate the
fluid inlet fitting in a comfortable position.

2. Apply air pressure to the fluid reservoir. Start with a
low setting of 1.4 bar (20 psi). If using a Nordson EFD
fluid reservoir, refer to the operating manual for further
instructions.

3. Install an appropriate size dispensing tip on the outlet
tip adapter. Use large tips for high viscosity materials
and small tips for low viscosity.
