HydraPak is operating hydraulic tool slowly or
erratically—engine operating normally
(continued).
One or more of the following flow restrictions:
a.
Hose kinked or damaged
b.
System filter clogged—fluid going through bypass.
c.
Suction filter clogged—fluid going through bypass.
d.
Steel line pinched or damaged.
e.
Heat exchanger clogged.
Erratic pressure caused by:
a.
Contamination in fluid—drain fluid, then inspect and replace
filters and fluid.
b.
Air in fluid—inspect for oil leaks and repair to correct.
Oil viscosity too heavy for cold climate—contact your local supplier
or Reimann & Georger Corporation for information.
Pump or motor damaged or worn—contact your nearest authorized
service center.
System relief valve malfunctioning:
a.
Stuck partially open
b.
Has broken spring.
HydraPak pressure relief setting of 2250 psi is too low for the
hydraulic tool being used—check tool pressure requirement.
Extension hoses too long:
a.
Hoses over 50 feet long add sufficient friction to the
hydraulic system to slow down the hydraulic tool slightly.
b.
Where possible, use as few quick disconnects as possible.
c.
An increase in system pressure may be required to
compensate for long hose runs. Consult your local supplier
or Reimann & Georger Corporation for information.
Hydraulic oil flow set too low—select 8 gpm on the 5-8 gpm knob.
Hydraulic tool is overspeeding
Flow is set too high—select 5 gpm on the flow control knob.
System overheats—engine operating normally.
Low fluid level in reservoir—fill to required level.
Air in fluid—inspect for oil leaks and repair to correct.
Severe operating conditions caused by:
a.
Extremely high ambient temperature-- use a higher viscosity
hydraulic oil. Consult your local supplier or Reimann &
Georger Corporation for details.
b.
Extended duty cycle—operate HydraPak intermittently to
provide cooling periods
