Safety Precautions
CAUTION: To prevent personal injury and/ or property damage,
•Study, understand, and follow all safety precautions and operating instructions before
using this jack. If the operator cannot read instructions, operating instructions and safety
precautions must be read and discussed in the operator’s native language.
• Onlyqualiedoperatorsmayinstall,operate,adjust,maintain,clean,repair,inspect,or
transport this jack.
•Inspect the condition of the jack before each use; do not use if damaged, altered, or in
poor condition.
•Wear eye protection that meets ANSI Z87.1, CE EN166, AS/NZS 1337, and OSHA
standards.
•The rated capacity for each stage of the jack is shown on the product decal, as well as in
this document. Do not exceed the rated capacity of each stage.
•Use on a hard, level surface with the wheels level.
• Liftonlyonareasofthevehicleasspeciedbythevehiclemanufacturer.
•Center load on jack saddle. Off-center loads can damage seals and cause jack failure.
•This is only a lifting device. Immediately after lifting, support vehicle with appropriate
means.
•Stay clear of a lifted load.
•Do not use this jack for anything other than its intended purpose. Do not use the jack to
move or dolly a vehicle.
•No alteration shall be made to this product.
•Use only those repair parts called out in the replacement parts list in this document. Items

Setup
1. See Figure 1. Loosen and remove the four screws holding the upper
cover. Remove the upper cover.
2. Note the handle position lever shown in Figure 2. Use the lever to
place the handle in Position 4 (horizontal) as shown in Figure 3.
3. Insert the bolt and washer near the bottom of the handle assembly.
See Figure 4.
Note: When storing the jack for a long period of time, remove the bolt
and washer to place the handle in Position 1.
4. Install the upper cover.
Operating Instructions
1. Verify the control lever is in the OFF position. See Figure 2.
2. Connect shop air supply to the jack. Recommended air pressure is
7–10 BAR (100–145 psi). Install an air lter / lubricator in the shop
air line, because water in the air line will damage the jack.
3. Move the control lever to the UP position to raise the saddle to the
contact point. Move the control lever to OFF.
Note: The extension may be used in the uppermost position if required
to meet the contact point.
4. Check the placement of the jack: lift only on areas of the vehicle as
specied by the vehicle manufacturer; center the load on the jack
saddle; avoid jack wheel obstructions such as gravel, tools, or uneven
expansion joints.
5. Move the control lever to UP to nish lifting the vehicle.
6. Immediately place approved support stands under the vehicle at points
recommended by the vehicle manufacturer. Slowly and carefully lower
the vehicle onto the support stands by pushing the control lever to
the DOWN position.
Bleeding Air from the Jack
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:
1. Move the control lever to DOWN, and hold it there for a few seconds.
2. Move the control lever to UP to complete a load-free lifting cycle.
3. Move the control lever to DOWN to retract the jack pistons. The
pistons should react in a smooth motion; if not, repeat Steps 1–3.

Inspection and Maintenance
CAUTION: To prevent personal injury,
• Onlyqualiedpersonnelshallperforminspectionsandrepairstothisjack.
•Before each use, an approved inspector must inspect the jack for bends, cracks, dents, elongated
holes, or missing hardware. If damage is found, discontinue use.
•Use only those repair parts called out in the parts list in this document. Items found in the parts
list have been carefully tested and selected by OTC.
•Disconnect the air supply hose from the jack before perfoming any maintenance or repair procedure.
See Figure 2 for the location of the air supply connection.
Inspection
Before each use, an approved inspector must inspect the jack for bends, cracks, dents, elongated holes, or
missing hardware. If damage is found, discontinue use.
Maintenance
•Periodically lubricate the moving parts of the jack using lubricating oil or grease.
•Use only anti-wear hydraulic jack oil (215 SUS viscosity at 100° F). The use of alcohol, hydraulic brake
uid, or transmission oil could damage the seals in the cylinder and result in jack failure.
•Periodically check the oil level in the cylinder: 1) Retract the pistons completely. 2) Remove the ller plug.
The oil level should be between the two marks on the rod. Rell as needed using approved hydraulic uid.
3) Install the ller plug.
•The greatest single cause of failure in hydraulic units is dirt. Keep the jack clean and well lubricated to
prevent foreign matter from entering the hydraulic system.
•Whenever the jack is not in use, fully retract the pistons to reduce the risk of corrosion.
Repair
When repairing the jack, use only those repair parts called out in the replacement parts list in this
document. Items found in the parts list have been carefully tested and selected by OTC.
Disposal
At the end of the useful life of the jack, dispose of the jack according to all state, federal, and local
regulations.
