WARNING
Should reel model 7342 be used to deliver
gasoline or aircraft fuel, the:
• delivery and connecting hose must contain a
grounding wire
• entire fuel delivery system must be properly
grounded
This prevents the build-up of static electricity.
Personal injury can occur due to fire and/or explo-
sion.
NOTE: The reel is grounded at the swivel
with a wave washer. See Figure 2.
High-capacity hose reel model 7342 is designed to:
• deliver fuel (such as diesel fuel, aircraft fuel, and
gasoline) and lubricating oils.
• mount to a lubrication truck or to a ceiling* or wall.
This reel mounts as a single unit or in banks of as
many as required. See Figure 4 for details.
NOTE: The Hose Guide Arms can attach to the
Base Assembly in five (5) different positions.
This model reel is spring-powered and self-retracting.
When the hose is extended, the reel can be latched on
either of two ratchet sections per revolution of the sheave.
