WARNINGS
1. Use a qualified technician to maintain the jack in good condition. Keep it clean for best and safest
performance.
2. The maximum load is 20 tons. DO NOT exceed this rated capacity.
3. Use this jack for lifting purpose only. DO NOT use it for any other purpose it is not designed to perform.
4. Keep children and unauthorized persons away from the work area.
5. Remove ill fitting clothing. Remove ties, watches, rings and other loose jewelry and contain long hair.
6. Wear ANSI approved safety goggles when operating the jack.
7. Keep proper balance and footing, do not overreach. Wear nonslip footwear.
8. Only use this jack on a surface that is stable, level, dry, not slippery, and capable of sustaining the
load. Keep the surface clean, tidy and free from unrelated materials and ensure that there is adequate
lighting.
9. When lifting a vehicle, apply the emergency brake and block all wheels.
10. Immediately after lifting, support the load with appropriate supporting equipments such as jack stands
of adequate capacity! DO NOT work under a load which is supported only by a jack.
11. Before lowering load, ensure that there are no obstructions underneath and that all persons are standing
clear.
12. DO NOT attempt to move the load while on the jack. The jack must only be used in a static position for
lifting and lowering loads. Ensure that the load remains stable at all times.
13. DO NOT use the jack if damaged, if any suspect parts are noted or it has been subjected to a shock load.
14. DO NOT operate the jack when you are tired or under the influence of alcohol, drugs or any intoxicating
medication.
15. DO NOT allow untrained persons to operate the jack.
16. DO NOT make any modifications to the jack.
17. DO NOT use brake fluid or any other improper fluid and avoid mixing different types of oil when adding
hydraulic oil. Only a good quality hydraulic jack oil should be used.
18. DO NOT expose the jack to rain or any other kind of inclimate weather.
19. If the jack needs repairing or there are any parts that need to be replaced, have it repaired by
authorized technicians and only use the replacement parts supplied by the manufacturer.
20. WARNING: The warnings, cautions and instructions discussed in this instruction manual cannot cover
all possible conditions and situations that may occur.

OPERATING INSTRUCTIONS

WARNING! Ensure that you read, understand and apply the safety instructions and warnings before use.
WARNING! Ensure that you have familiarized yourself thoroughly with the product and the hazards
associated with its improper use.
1. Before first use of this product, pour a teaspoon of good quality air tool lubricant into the hose quick
coupler-male of the air quick coupler-female, then connect it to air source and turn on the air valve
and work for 3 seconds to evenly distribute lubricant.
2. Use the slotted end of the handle to turn the release valve clockwise until it is firmly closed.
3. Apply the emergency brake and use wheel chocks to block all wheels to prevent any movement of the
vehicle being lifted.
4. Place the jack into position and adjust the extension screw on part as needed.
NOTE: Check in your vehicle owner’s manual for the location of recommended lift point.
5. Connect the air quick coupler-male into the shop air supply hose quick coupler-female, then turn on
the air valve.
6. Raise the load to desired height, turn off the air valve and immediately USE JACK STAND PAIR with
adequate capacity to support the load.
7. When air source is not available, insert the big end of the handle into the handle bracket, pump it
manually to raise the load to desired height. Then immediately transfer the load to appropriate support
devices such as jack stands.
WARNING! Be sure all tools and personnel are clear before lowering load.
8. When work is done, raise load enough to carefully remove the jack stands. Then SLOWLY and CAREFULLY
lower the load by turning the release valve counterclockwise (use the slotted end of the handle) in
extremely small increments, then lower the extension screw by turning it clockwise as needed and
remove the jack.
WARNING! Dangerous dynamic shock loads are created by quick opening and closing the release
valve when the load is being lowered. The resulting overload may cause hydraulic system failure
which could cause severe personal injury and/or property damage.

MAINTENANCE
1. Clean the outside of the jack with a dry, clean, soft cloth and periodically lubricate the joints, extension
screw and all moving parts with a light oil as needed.
2. When not in use, store the jack in a dry location with ram and extension screw fully lowered.
3. Purge the hydraulic system to eliminate any air in the system. If jack efficiency drops or jack doesn’t
work:
A. If manual operation performs poorly, use the slotted end of the handle to turn the release valve 1-1/2
turns counterclockwise and remove the oil filler plug by gently pulling, insert the handle into the
handle bracket and pump it 10 to 15 times, then replace the filler plug.
B. If air operation performs poorly, connect the air inlet fitting to air source, use the slotted end of the
handle to turn the release valve 1-1/2 turns counterclockwise and remove the oil filler plug by gently
pulling, turn on the air valve to let the pump work for one minute, then replace the filler plug.
4. Check the hydraulic oil: place the jack in an upright position, completely lower the ram and remove the
filler plug, if it is not adequate, fill with high quality hydraulic jack oil to the lower rim of the fill hole, purge
away air from the hydraulic system, top off with more hydraulic oil, then replace the filler plug.
5. For best performance and longest life, replace the complete jack oil at least once per year: With the ram
fully lowered, remove the oil filler plug, lay the jack on its side and drain the oil into a suitable container,
then fill with high quality hydraulic jack oil, reinstall the filler plug.
NOTE: Dispose of hydraulic oil in accordance with local regulations.
NOTE: It is recommended that an annual inspection be done by qualified technicians.
