Detailed Troubleshooting — Hydraulic Foot Pump
The following tools are required to resolve the issues listed
above:
5mm hex key wrench
Standard (flat head) screwdriver
Adjustable crescent wrench
Hydraulic Fluid Level Adjustment
1. Remove the fill/breather plug.
2. Hydraulic fluid level should be 2 - 2.5 inches
below the bottom of the fill hole when the
cylinder rod is fully lowered. Do not overfill the
reservoir; if overfilled, oil may leak or seep
around the fill plug.
ONLY use ISO AW-32 anti-wear hydraulic
pump oil. The oil must be clean; strain the oil, if
necessary, before adding it to the reservoir.
Remove Air Trapped Inside Hydraulic System
1. Pump the foot pedal until the cylinder rod is fully
extended. The small hole near the base of the
rod will pass by the high pressure seal and air
will automatically vent into the reservoir tube.
Release Pedal Adjustment
1. Loosen the release pedal screw retaining nut (p.
13).
2. Loosen the release pedal screw: ½ to a full
counterclockwise turn using either a 5mm hex
key wrench (Allen wrench) or flat blade
screwdriver.
3. Apply a test weight to the deck; pump the foot
pedal until the deck rises ~2ft; then press the
release pedal down. [If the deck lowers, turn the
release pedal screw by another ½ turn, and
repeat step 3. The deck should not lower when
you press the release pedal.]
4. Turn release pedal screw clockwise 1/8 to ¼
turn; repeat step 3. The deck now should lower;
if it does not, turn the screw clockwise by
another 1/8 turn. Repeat this step until the
desired deck-lowering rate is achieved.
5. Tighten the retaining nut. To prevent the screw
from rotating while tightening the nut, either hold
the screw with your fingers or insert the 5mm
hex key wrench (or flat blade screwdriver) into
the fitting.
Proper Hydraulic Fluid Level
Inlet Check Valve Assembly Cleaning
1. Remove inlet check port plug with a crescent wrench
(see p. 14).
2. Clean the valve components.
3. While the valve is disassembled, pump the foot pedal at
least 5 times. Fluid will discharge from the inlet check
valve opening, which should dislodge debris clogging the
valve.
4. Reassemble the valve & reconnect the port plug.
5. Add hydraulic fluid as necessary according to the
“Hydraulic Fluid Level Adjustment” instructions above.
