Safety Precautions
WARNING: To prevent personal injury and/or equipment damage,
•Study, understand, and follow all instructions before operating this device. If the operator
cannotreadorunderstandtheseinstructions,theoperatinginstructionsandsafetyprecautions
must be read and discussed in the operator’s native language.
•Wear eye protection that meets OSHA and ANSI Z87.1 standards.
•Inspect the jack before each use; do not use the jack if it is damaged, altered, or in poor
condition. No alterations may be made to this product. Use only those attachments and/or
adapters supplied by the manufacturer.
•Lift only on areas of the vehicle as specified by the
vehicle manufacturer.
•Do not exceed rated capacity.
•Use only on a hard, level surface.
•Center the load on the jack saddle. Off-center loads can
damage seals and cause jack failure.
•
This is a lifting device only. Immediately after lifting,
support the vehicle with appropriate means.
•Stay clear of a lifted load.
•Do not use the jack to move or dolly a vehicle.
Setup
1. Remove the upper cover. See Figure 1.
2. Remove the metal rod, and connect the blue plastic tube (supplied).
3. Place the handle in Position 4 (Fig. 2), and insert the bolt and washer near
the bottom of the handle assembly. See Fig. 3. Note: Remove the bolt and
washer to put the handle in Position 1 for storage.
4. Replace the cover.
Operating Instructions
1. Verify the control lever is in the OFF position. See Figure 4.
2. Connectshopairsupplytothejack.Recommendedairpressureis100–145
psi (7–10 BAR). Install an air filter / lubricator in the shop air line, because
water in the air line will damage the jack.
3. Move the control lever to UP to raise the saddle to the contact point. Move
the control lever to OFF.
4. Check the placement of the jack; the load must be centered on the jack
saddle. Avoid jack wheel obstructions such as gravel, tools, or uneven
expansion joints.
5. Move the control lever to UP finish lifting the vehicle.
6. Immediatelyplaceapprovedsupportstandsunderthe vehicle’sliftingpoints
(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
Aircanaccumulatewithinahydraulicsystemduringshipmentorafterprolonged
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.

Preventive Maintenance
IMPORTANT:Thegreatestsinglecauseoffailureinhydraulicunitsisdirt.Keeptheservicejackcleanandwelllubricatedtoprevent
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 pistons 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 only replacement parts that are approved by the manufacturer. Disconnect the air supply before performing any maintenance
operation.
3. Regularly lubricate the moving parts in the wheels, arm, and handle using a high quality grease.
4. To check the oil level, completely lower the pistons. Remove the dipstick. 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,

oil with an ISO viscosity grade of 22 or SAE viscosity grade of SW.

Troubleshooting Guide
CAUTION:Topreventpersonalinjury,allinspection,maintenance,andrepairproceduresmustbeperformed
when the jack is free of a load (not in use) and disconnected from the air supply. Repair procedures must be
performed in a dirt-free environment by qualified personnel who are familiar with this equipment.
Trouble Cause Solution
5. Replacetheoil in thereservoirat least onceperyear: Disconnect theair supply; remove the
cover and connecting tube (see Figure 5); and let the oil drain into an approved container.
Attachthe connecting tube;removethedipstick;addapproved,anti-wear, hydraulicjackoil;
check the oil level (between the two marks on the dipstick); install the dipstick and cover.
6. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. cracked, damaged housing c. leaking hydraulic fluid e.loose hardware
b. excessive wear, bending, other damage d. scored, damaged piston rod f. modified equipment
7. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external surfaces of the jack.
