you many years of service. Follow the maintenance instruc-
tions carefully to keep your equipment in good working
condition. Never perform any maintenance on the
equipment while it is under a load.
Inspection
You should inspect the product for damage, wear, broken
or missing parts (e.g.: pins) and all components function
before each use . Follow lubrication and storage
instructions for optimum product performance.
Binding
If the product binds while under a load, use equipment with
equal or a larger load capacity to lower the load safely to
the ground. After un-binding; clean, lubricate and test that
equipment is working properly. Rusty components, dirt,
or worn parts can be causes of binding Clean and lubri
-
cate the equipment as indicated in the lubrication section.
Test the equipment by lifting without a load. If the binding
continues contact Customer Service.
Cleaning
If the moving parts of the equipment are obstructed, use
cleaning solvent or another good de-greaser to clean the
equipment. Remove any existing rust, with a penetrating
lubricant.
Lubrictation
This equipment will not operate safely without proper lu
-
brication. Using the equipment without proper lubrication
will result in poor performance and damage to the equip
-
ment. Some parts in this equipment are not self-lubricating,
inspect the equipment before use and lubricate when
necessary. After cleaning, lubricate the equipment using a
- Use a good Lubricant on all moving parts.
- For light duty use lubricate every once a month.
- For heavy and constant use lubrication recommended
every week.
Rust Prevention:
- Check ram’s and pump plunger’s on the power unit
assemblies daily for any signs of rust or corrosion.
Without a load lift the equipment as high as it goes and
look under and behind the lifting points. If signs of rust are
visible clean as needed.
Grease Fittings
-
need to be greases and lubricated.
How the Jack Operates
With release valve closed, an upward stroke of the jack
handle draws oil from the reservoir tank into the plunger
cavity. Hydraulic pressure holds the valve closed, which
keeps the oil in the plunger cavity. A downward stroke of
the jack handle releases oil into the cylinder, which forces
the ram out. This This raises the saddle. When the ram
reaches maximum extension, oil is bypassed back into the
reservoir to prevent an over extended ram stroke and
possible damage to the jack. Opening the release valve
hydraulic pressure on the ram, which results in lowering
the saddle.
Storing the Jack
1. Lower the Lifting Arm.
2. Store in a dry location, recommended indoors.
Note: If the jack is stored outdoors, be sure to lubricate
all parts before and after use to ensure the jack stays in
good working condition.
To Add Jack Oil:
1. Position the jack on level ground and lower the saddle.
2. Use a Phillips head screwdriver to remove the cover
plate.
3. Remove the oil plug.
4. Fill the oil case until oil level is just beneath the lower rim
5. Replace oil plug.
6. Perform the Air Purge Procedure.
To Replace Jack Oil:
1. Fully open release valve by turning handle
counter-clockwise.
2.

clear when pouring.
4. Fill just beneath lower rim of hole. Replace oil plug.
5. Perform Air Purge Procedure described below.
WARNING:
Do not use motor oil in the jack.
Only use Anti-Foaming Jack Oil.
We recommend “Black Jack”, Jack Oil.
ALWAYS USE A GOOD GRADE HYDRAULIC JACK OIL.
DO NOT USE HYDRAULIC BRAKE FLUID, ALCOHOL,
GLYCERINE, DETERGENT, MOTOR OIL OR DIRTY OIL.
USE OF AN UN-RECOMMENDED FLUID CAN CAUSE
DAMAGE TO A JACK.
