MHJ3T 3 TON HYBRID FLOOR JACK
It is recommended that the jack be stored in a dry location with all wheels touching the ground on a relatively level surface.
PROPER STORAGE
Important: Service jacks are self-contained devices used for lifting, but not sustaining, a partial vehicular load. In accordance with ASME-PASE
Load Sustaining Test: “A load not less than the rated capacity…shall not lower more than 1/8" (3.18mm) in the first minute, nor a total of .1875"
(4.76mm) in 10 minutes.” Lowering within this range is considered normal operation and is NOT a warrantable defect.
PROBLEM
ACTION
1. Unit will not lift rated load.
Purge air from hydraulic system by following procedure under INSTRUCTIONS FOR BLEEDING AIR.
2. Unit will not sustain rated load or feels “spongy” under rated load. Purge air from hydraulic system as above.
3. Unit will not lift to full height.
Purge air from hydraulic system as above.
4. Unit will not lower completely.
Check oil level. Make sure hydraulic system is not overfilled.
5. Handle tends to raise up while the unit is under rated load.
Pump the handle rapidly several times to push oil past ball valves in power unit.
6. Unit still does not operate.
Contact customer service.

PREVENTIVE MAINTENANCE
1.
Always store the jack in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust, or any other harmful
elements. The jack must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter before using.
2.
The jack must be lubricated periodically in order to prevent premature wearing of parts. A general purpose grease must be applied to caster wheels,
front axle, elevator arm, handle base pivot bolts, release mechanism and all other bearing surfaces. Worn parts resulting from inadequate or no
lubrication are not eligible for warranty consideration. IMPORTANT: In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake
fluid, or transmission oil in the jack. Use hydraulic jack oil, a light turbine oil, Chevron AW ISO 32 or Unocal Unax AW 150.
3.
Every jack owner is responsible for keeping the jack labels clean and readable. Use a mild soap solution to wash external surfaces of the jack but not
any moving hydraulic components. Contact Matco Tools for replacement label if your jack label is not readable.
4.
Inspect the jack before each use. Do not use the jack if any component is cracked, broken, bent, shows sign of damage or leaks hydraulic fluid. Do not
use the jack if it has loose or missing hardware or components, or is modified in any way. Take corrective action before using the jack again.
