Preventive Maintenance - SPX 5093 Instrucciones De Funcionamiento

Parts List & Operating Instructions
1. Move the control lever to the OFF position.
2. Connect the air supply. Recommended air pressure is 100–145 psi (7–10 BAR). The shop air line must have
an air filter/lubricator unit; water in the air line will damage the jack.
Note: Air can accumulate within a hydraulic system during shipment or after prolonged use. This entrapped
air causes the jack to respond slowly or feel "spongy." To remove the air:
A. Push the control lever DOWN, and hold it there for a few seconds.
B. Push the control lever UP to effect a complete lifting cycle.
C. Push the control lever DOWN to retract the jack pistons. (The pistons should react in a smooth motion.
If not, repeat Steps A–C.)
3. Push the control lever UP to raise the saddle to the contact point.
4. Check the placement of the jack; the load must be centered on the jack saddle. IMPORTANT: Avoid wheel
obstructions such as gravel, tools, or uneven expansion joints.
5. Finish lifting the vehicle. Do not attempt to raise the jack beyond its travel stops.
6. Place approved support stands under the vehicle's lifting points (points recommended by the vehicle
manufacturer) that will provide stable support. Before making repairs on the vehicle, lower it onto the support
stands by SLOWLY and CAREFULLY pushing the control lever DOWN.
IMPORTANT: The greatest single cause of failure in hydraulic units is dirt. Keep the service 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, with the piston completely retracted, in a well-protected area where it will not be exposed to
corrosive vapors, abrasive dust, or any other harmful elements.
2. Use approved replacement parts to avoid damage to the jack.
3. Regularly lubricate the moving parts in the wheels, arm, and handle using a high quality grease.
4. Replace the oil in the reservoir at least once per year. To check the oil level, lower the jack pistons completely.
The oil level should be between the two marks on the dipstick. If necessary, add approved anti-wear hydraulic
jack oil, and install the dipstick again. IMPORTANT: The use of alcohol, hydraulic brake fluid, or
transmission oil could damage the seals and result in jack failure. Use only HL or HM type hydraulic
oil with an ISO viscosity grade of 22 or SAE viscosity grade of SW. NEVER use brake fluid.
5. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. cracked, damaged housing
b. excessive wear, bending, other damage
6. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external
surfaces of the jack.
