Parts List & Operating Instructions
Lifting from the End
1. Position the jack at the center of the fork lift truck. See Figure 5.
2. Chock the wheels at the opposite end of the fork lift.
CAUTION: To prevent injury or equipment damage,
Do not lift from the end of the fork lift if the contact surface is
sloped or rounded, such as in the counter weight areas.
When lifting 3-wheeled trucks, never lift the 2-wheeled end.
IMPORTANT: The greatest single cause of failure in hydraulic units is dirt. Keep the fork lift jack clean and well
lubricated to prevent foreign matter from entering the system. If the jack has been exposed to rain, snow, sand,
or grit, it must be cleaned before it is used.
1. Store the jack in a well-protected area where it will not be exposed to corrosive vapors, abrasive dust, or any other
harmful elements.
2. Regularly lubricate the stem of the pump plunger with heavy grade machine oil.
3. To check the oil level, place the fork lift jack on level ground, and completely retract the ram. Remove the plug from the
oil filler hole. The oil level should be within 1/4" of the filler plug hole. If necessary, add approved anti-wear hydraulic
jack oil (Mobile DTE #13 or equivalent), and install the filler plug again. IMPORTANT: The use of alcohol, hydraulic
brake fluid, detergent motor oil, or automatic transmission fluid (ATF) could damage the seals and result in jack
failure.
4. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. Cracked or damaged housing
b. Excessive wear, bending, or other damage
c. Leaking hydraulic fluid
