COMPONENT RUPTURE HAZARD
The maximum working pressure of each component
in the system may not be the same. To reduce the
risk of overpressurizing any component in the sys-
tem, be sure you know the maximum working pres-
sure of each component.
Never exceed the maximum
working pressure of the lowest rated component in
the system. Overpressurizing any component can
result in rupture, fire, explosion, property damage and
serious injury.
The equipment must be bonded (grounded) directly
to the truck. Grounding reduces the risk of static
shock due to static build up on the equipment.
NOTICE
Fuses (user supplied) are required on all models. To
avoid equipment damage:
• Never operate the Dyna-Star Pump models with-
out a fuse installed.
• A fuse of the correct voltage and amperage must
be installed in line with the power entry to the
system. Graco recommends using 35A fuses.
HEAVY EQUIPMENT HAZARD
Equipment is heavy. To avoid injury:
• Be sure unit is securely mounted before operation.
• Do not lift pressurized equipment.
• Lifting or moving heavy equipment incorrectly can
cause serious injury. To avoid serious injuries, such
as muscle strain or back injuries, when moving
pump always use a lifting aid secured to the pump
lift ring. See Technical Data, in the pump
instruction manual for pump weight.
