PRODUCT DESCRIPTION
This Hydraulic Service Jack is designed to lift, but not support, one end of a vehicle. MagicLift™ service jacks have
a unique feature that provides fast, no load lifts to the jacking point, at which time it lifts in approximately 0.75~0.2"
increments.
WARNING: Do not use hydraulic jack as stand-alone device. After lifting, immediately support the lifted vehicle
with a pair of appropriately rated jack stands.
PREPARATION/ASSEMBLY
Before Use
1. Assemble the 2-piece handle with provided bolt.
2. Always secure the handle into the handle fork by means of the bolt and lock washer provided. Tighten securely
to prevent accidental removal of handle while in use.
WARNING: Do not lift or carry jack by handle. Handle could dislodge and jack fall, resulting in possible injury
or property damage.
3. Before using this product, read the operator's manual
completely and familiarize yourself thoroughly with
the product and its components, and recognize the
hazards associated with its use.
4. Verify that the product and application are compatible.
5. To familiarize yourself with basic operation, locate and
turn the release valve (pump 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 turn from
the closed position. This is the ‘OPEN’ release valve
position used to lower the saddle.
6. With saddle fully lowered and release valve closed,
pump the handle. If lift arm responds immediately,
jack is ready for use. If jack does not respond, follow
Bleeding/Venting Trapped Air instruction below.
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 oil plug.

!WARNING
X
!WARNING
• Study, understand, and follow all instructions
before operating this device.
• Do not exceed rated capacity.
• Use only on hard, level surface.
• Lifting device only. Immediately after lifting,
support the vehicle with appropriate means.
• Lift only on areas of the vehicle as specied 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 markings may result in
personal injury and/or property damage.
7. Ensure that jack rolls freely. Raise and lower the unloaded saddle throughout the entire lifting range before
putting into service to ensure the pump operates smoothly. Replace worn or damaged parts and assemblies with
authorized replacement parts only.
Bleeding/Venting Trapped Air
With the release valve in the OPEN position (step 5b. above) and with saddle fully lowered, locate and remove the
oil ller plug. Pump handle 6 to 8 full strokes. This will help release pressurized air which may be trapped within the
reservoir. Reinstall the oil ller plug and check operation.
OPERATION
Lifting
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, pump handle until saddle contacts lift point. To lift, pump handle until load reaches desired height.
5. Transfer the load to appropriately rated jack stands.
Lowering
WARNING: Clear all tools and personnel before lowering vehicle. Open release valve slowly. The further
the pump handle is turned counter-clockwise, the faster the load will descend. Maintain control of load at all
times.

OPERATION (cont.)
1. Raise load high enough to clear the jack stands.
2. Remove jack stands carefully.
3. Turn handle counter-clockwise, but no more than 1/2 full 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. Use 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
NOTICE: Use premium quality 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 premature failure of the jack and the
potential for sudden and immediate loss of load.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Remove vent srew.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall vent screw.
Changing oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With saddle fully lowered, remove vent screw.
2. Lay the jack on its side and drain the uid into a suitable container.
NOTICE: Dispose of hydraulic uid in accordance with local environmental regulations.
3. Fill with oil until ~3/16" above the inner cylinder as seen from the oil filler hole. Reinstall vent screw.
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
wheels, casters and pump assemblies move freely.
Cleaning
Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
NOTICE: Do not use sandpaper or abrasive material on ram and pump piston surfaces.
Storage
When not in use, store the jack with saddle fully lowered.
