Too much tension reduces the life of the
spring.
When the hose is fully extended from
the reel, the power spring should be a
minimum of

condition.
18 Release all pressure within the system.
WARNING
Disconnect the air supply line to the
pump's motor.
Into an appropriate container, operate
the control valve to discharge remaining
pressure within the system.
19 Remove the control valve and the hose
stop from the delivery hose.

Reel operation

WARNING
Do not exceed lowest pressure
rating of any component in system.
Never point a control valve at any
portion of body or another person.
Lubricant discharged at high velocity
can penetrate skin and cause severe
injury. Should any fluid appear to
puncture skin, get medical care
immediately.
Ensure all components are in
operable condition. Replace any suspect
parts prior to operation. Personal injury
can occur.
Hold delivery hose securely until reel
is securely latched or fully retracted.
Uncontrolled retraction can result in
personal injury.
Latch lockout
Over-rotation of the reel
NOTE
Do not extend the hose from the reel too
rapidly. Too much velocity (when the
hose is fully extended) can cause the
reel to over-rotate and latch.
Should latch lockout occur, pulling on the
hose will not release the latch mechanism.
With the reel latch in this condition it will
be necessary to have an assistant maintain
tension on the hose while the latching
mechanism is manually released.
WARNING
The reel is under maximum spring
tension. Personal injury can occur.
