HO150 hydraulic fluid. Any anti-wear hydraulic fluid with a viscosity grade of 150 SUS at 100° F (ISO 32 @ 40° C)
such as AW 32 or Dexron transmission fluid is acceptable.
Troubleshooting Guide (DCR-880-H & -HP):
Lower and unload the carriage before beginning service work on the unit. Purge all hydraulic pressure from the foot pump
by holding the release open for two seconds once the drum is lowered to the floor.
If the pump malfunctions in any of the following ways:
• Cylinder rod fails to extend while pumping the foot treadle;
• Cylinder rod rises and lowers with each stroke of the foot pump
treadle; or
• Carriage descends on its own.
Try each of the following fixes until the pump works properly
1. Hydraulic fluid level adjustment:
a. Fully lower the carriage by pressing the release lever and
holding it down.
b. Remove the fill/breather plug and insert a clean, flexible object,
like a cable tie, wire, or twist tie, down inside the cylinder to
determine the oil level. The oil surface should be approximately
2" below the fill hole. If oil is needed,
Any anti-wear hydraulic fluid with a viscosity grade of 150 SUS at
100° F (ISO 32 @ 40° C) such as AW 32 or Dexron transmission
fluid is acceptable.
2. Flush contamination from the check assemblies. Press the release
pedal down as far as it will go while pumping the foot treadle rapidly.
This will create turbulence inside the pump, which might dislodge
contamination that might be preventing one of the check balls from
seating properly.
3. Release pedal adjustment
a. Loosen the release pedal
screw retaining nut.
b. Loosen the pedal screw
a full counterclockwise turn
using either a hex key
wrench (Allen wrench) or a
flat blade screw driver.
c. Grasp an empty drum with
the drum gripping
mechanism and pump the
foot pedal until the drum
rises several inches above
the ground. Press the
release pedal. If the drum
lowers, turn the screw

another / counterclockwise
2
turn. Raise the drum again.
Continue this process until
the drum maintains elevation.
The drum should not lower
when the release pedal is
pressed.
d. Turn the release pedal screw clockwise
Press the release lever. The drum should lower now. If
it does not, turn the screw clockwise by another
and again press the release pedal. Continue this
process until the desired lowering speed is achieved.
e. Tighten the retaining nut. To prevent the screw from
rotating at the same time, either hold the screw with
your fingers or use the hex wrench or screwdriver into
the fitting.

4. Clean the Inlet Check
Valve Assembly
a. Remove inlet check
port plug with a
crescent wrench and
remove the valve.
b. Clean the valve
components.
c. While the valve is
disassembled, pump
the foot pedal 5 or
more times. Fluid will
discharge from the
port, which should
dislodge debris
clogging the valve.
d. Reassemble the valve
& reconnect the port
plug.
turn e. Add hydraulic fluid as
necessary according
to the "Hydraulic Fluid
Level Adjustment"
instructions above.
