SAFETY and GENERAL INFORMATION
Save these instructions. For your safety, read, understand, and follow the information provided with and on this jack
before using. The owner and operator of this equipment shall have an understanding of this jack and safe operating
procedures before attempting to use. The owner and operator shall be aware that use and repair of this product
may require special skills and knowledge. Instructions and safety information shall be conveyed in the operator's
native language before use of this jack is authorized. If any doubt exists as to the safe and proper use of this jack,
remove from service immediately.
Inspect before each use. Do not use if broken, bent, cracked or damaged parts are noted. Any jack that appears
damaged in any way, or operates abnormally shall be removed from service immediately. If the jack has been or
suspected to have been subjected to a shock load (a load dropped suddenly, unexpectedly upon it), immediately
discontinue use until jack has been checked by a factory authorized service center (contact distributor or manufacturer
for list of authorized service centers). It is recommended that an annual inspection be done by qualied personnel.
Labels and Operator's Manuals are available from manufacturer.
PRODUCT DESCRIPTION
This Service Jack is designed to lift, but not support, one end of a vehicle. Immediately after lifting, loads must be
supported by a pair of appropriately rated jack stands. This service jack has a unique feature that provides fast, no
load lifts to the jacking point, at which time it lifts in approximately 0.75 ~ 2" increments.
NEVER use hydraulic jack as stand-alone device. After lifting, immediately support the lifted vehicle with
a pair of appropriately rated jack stands. NEVER place ANY portion of your body beneath the vehicle when
lifting OR lowering!

PREPARATION
Assembly
Insert handle into the handle sleeve. Tighten the bolt on handle sleeve to prevent accidental removal of handle while
in use.
Before Use
1. Verify that the product and application are compatible, if in doubt contact your local Fastenal Representative or
visit www.fastenal.com to locate your nearest store.
2. Before using this product, read the operator's manual completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards associated with its use.
3. To familiarize yourself with basic operation, locate and turn the release valve (handle):
a. Clockwise until rm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used to
raise the saddle.
b. Counter-clockwise, but no more than 1/2 a turn from the closed position. This is the ‘OPEN’ release valve
position used to lower the saddle.
4. With saddle fully lowered, remove the oil ller plug. *Pump 6 to 8 full strokes. Check oil level. Proper oil level will vary
from just covering the ram cylinder to 3/16” above it as seen from the oil ller hole. Reinstall the oil ller plug.
5. Ensure that jack rolls freely. Raise and lower the unloaded saddle throughout the lifting range before putting into
service to ensure the pump operates smoothly. Replace worn or damaged parts and assemblies with factory
authorized replacement parts only.
*Bleeding / Venting Trapped Air
With the release valve in the OPEN position (3b.) and with saddle fully lowered, locate and remove the oil ller
plug. Pump 6 to 8 full strokes. This will help release any pressurized air which may be trapped within the reservoir.
Reinstall the oil ller plug.
!WARNING
• Study, understand, and follow all printed
materials provided with/on this product before use .
• Do not exceed rated capacity.
• Use only on hard, level surface.
• This is a lifting device only!
• Immediately after lifting, support the load with
a pair of appropriately rated jack stands.
• Lift only on areas of the vehicle as specied by
the vehicle manufacturer.
•
Do not move or dolly the vehicle while on the jack.
• No alterations shall be made to this product.
• Failure to heed these marking may result in
personal injury and/or property damage.
To avoid crushing and related injuries:
• Never work on, under or around a load supported
only by hydraulic jack.

OPERATION
Lifting
Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on areas of the
 vehicleasspeciedbythevehiclemanufacturer.
1. Follow the vehicle manufacturer’s recommended guidelines for lifting. Engage the emergency brake and chock
each unlifted wheel in both directions to prevent inadvertent vehicle movement.
2. Close the release valve by turning the handle clockwise until rm resistance is felt.
3. Refer to the vehicle manufacturer owner’s manual to locate approved lifting points on the vehicle. Center jack
saddle under lift point.
4. Verify lift point, then pump handle to contact lift point. To lift, pump handle until load reaches desired height.
5. Transfer the load immediately to appropriately rated jack stands.
NEVER use hydraulic jack as a stand alone device! ALWAYS transfer the lifted load IMMEDIATELY to a
pair of appropriately rated jack stands. Use one pair of jack stands per vehicle. Rated capacity is per
pair only! Do not exceed rated capacity.
Lowering
Be sure all tools and personnel are clear before lowering load. Slowly open the release valve! The more
you turn the handle counter-clockwise, the faster the load will come down. Maintain control of the rate
of speed at which the load lowers at all times!
1. Raise load high enough to clear the jack stands.
2. Remove jack stands carefully.
3. Slowly turn the handle counter-clockwise, but no more than 1/2 a turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the malfunctioning jack and then the jack stands.
c. Using the functioning jack to lower the vehicle.
4. After removing jack from under the vehicle, fully lower the saddle to reduce ram exposure to rust and
contamination.
MAINTENANCE
Important: Use ONLY good grade hydraulic jack oil. Avoid mixing different types of uid and Never use brake uid,
turbine oil, transmission uid, motor oil or glycerin. Improper uid can cause failure of the jack and the potential for
sudden and immediate loss of load. We recommend Mobil DTE 13M.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil ller plug.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall the oil ller plug.
Changing oil
For best performance, replace the complete uid supply at least once per year.
1. With saddle fully lowered, remove oil ller plug.
2. Lay the jack on its side and drain the uid into a suitable container.
Note: Dispose of hydraulic uid in accordance with local regulations.
3. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall oil ller plug.

TROUBLESHOOTING
Symptom Possible Causes Corrective Action
Jack will not lift load • Release valve not tightly closed
• Load is too heavy
• Ensure release valve tightly closed
• Consider higher capacity jack
Jack will lift, but not maintain
pressure
•Release valve not tightly closed
• Hydraulic unit malfunction
•Ensure release valve tightly closed
• Discontinue use, contact your local
Fastenal Representative or visit
www.fastenal.com to locate your
nearest store
Jack will not lower after unloading • Reservoir overlled
• Linkages binding
• Drain uid to proper level
• Clean and lubricate moving parts
Poor lift performance • Fluid level low
•Air trapped in system
• Ensure proper uid level
•With ram fully retracted, remove
oil ller plug to let pressurized air
escape, reinstall oil ller plug
Will not lift to full extension • Fluid level low • Ensure proper uid level
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
pump assemblies move freely.
Cleaning
Periodically check the pump piston and ram plunger for signs of rust or corrosion. Clean as needed and wipe with
an oily cloth.
Storage
When not in use, store the jack with pump piston and ram plunger fully retracted.
