FIGURE #12 —Pin and Roller Locations
FIGURE #13 —Acceptable Hydraulic Oils
Note: Most petroleum based anti-ware hydraulic fluids with a 32,
46 o 68 ISO viscosity grade will work with this system. Verify
with JH Industries, Inc. before using anything other than what is
listed in the table above.
Do not use brake fluid or any other fluids not
approved by the manufacturer. Use of fluids not
approved by the manufacturer may attack the
hydraulic systems seals and hoses.
For extreme cold applications we recommend an oil
immersion heater.
For extreme warm temperature ranges of +20º to
+140º Fahrenheit, you may switch to 10W30 motor
oil. If ambient temperatures are expected above
140º Fahrenheit, consult factory.
Hydraulic Fluid:
Hydraulic fluid under high pressure can cause
personal injury. Before any maintenance is
commenced release all pressure from the
hydraulic system. High pressure fluid can
pierce skin and enter the blood system which
could cause serious injury or death.
The relief valve is designed to protect the
operator, personnel near the lift during usage
and the hydraulic system in the dock lift. The
relief valve is factory set for a specific pressure,
never change the settings of this valve, the
system could build up extreme pressures which
would cause hydraulic components to fail and
serious injury or death may occur.
Changing Hydraulic Fluid:
1. The hydraulic reservoir is located attached to the
hydraulic pump.
2. Lower the dock lift and depress the down button
for 10 seconds after lowering to relieve the
system of all pressure.
3. Raise the hydraulic pump and tank off of the
ground so a pan or bucket can be placed under
the tank. On the side of the unit at the base is a
drain plug (
See FIGURE #13 ). Place the pan or
