MAINTENANCEINSTRUCTIONS
If you use and maintain your equipment properly, it will give you many years of service. Follow the
maintenance instructions 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 that 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 lubricate 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 degreaser to
clean the equipment. Remove any existing rust, with a penetrating lubricant.
Lubrication
This equipment will not operate safely without proper lubrication. Using the equipment without proper
lubrication will result in poor performance and damage to the equipment. 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 high grade light penetrating oil or lubricating spray.
-For light duty use lubrication once a month.
-For heavy and constant use lubrication recommended every week.
-NEVER USE SANDPAPER OR ABRASIVE MATERIAL ON THESE SURFACES!
Rust Prevention:
-Check rams and pump plungers on the power unit assemblies daily for any signs of rust or corrosion.
Without a load on the equipment extended hydraulic rams to check if signs of rust are visible clean as
needed.
How the Ram 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 extends
the ram. 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 allows oil to
flow back into reservoir. This releases hydraulic pressure on the ram, which results in lowering the ram.
Storing the Ram
1. Fully Retract Ram after use.
2. Place the handle in the upright position.
3. Store in a dry location, recommended indoors.
Note: If the press is stored outdoors, be sure to lubricate all parts before and after use to ensure the
press stays in good working condition.

14
To Add Oil:
1. Set Pump Unit upright on a level surface.
2. Remove the Screw with its attached dipstick.
3. Add 0.22 quarts (about 7.43oz., or 770ml) of oil. The oil level should be near Position (A).
Use a high grade anti-foaming hydraulic oil.
KEEP DIRT AND OTHER MATERIALS CLEAR WHEN POURING.

15
Replace the Oil Fill Screw.
4. Perform the Air Purge Procedure.
To Replace Oil:
1. Set Pump Unit upright on a level surface.
2. Remove the screw with its attached dipstick .

16
3. Turn the Pump Unit on its side so that old oil will drain from the oil fill hole.
4. Set Pump Unit upright on a level surface.
5. Add 0.22 quarts (about 7.43oz., or 770ml) of oil. The oil level should be near Position (A).
Use a high grade anti-foaming hydraulic oil.
KEEP DIRT AND OTHER MATERIALS CLEAR WHEN POURING.

17
6. Replace the Oil Fill Screw.
7. Perform the Air Purge Procedure.
ADDITIONAL WARNINGS:
DO NOT USE MOTOR OIL IN THE JACK.
ONLY USE ANTI-FOAMING 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 A NON-RECOMMENDED FLUID CANCAUSE DAMAGE TO A JACK.
AVOID MIXING DIFFERENT TYPES OF FLUID AND NEVER USE BRAKE FLUID, TURBINE OIL,
TRANSMISSION FLUID, MOTOR OIL OR GLYCERIN. IMPROPER FLUID CAN CAUSE PREMATURE
FAILURE OF THE JACK AND THE POTENTIAL FOR SUDDEN AND IMMEDIATE LOSS OF LOAD.
DISPOSE OF HYDRAULIC FLUID IN ACCORDANCE WITH LOCAL REGULATIONS.
LUBRICATION
1. Clean the outside of the press with a dry, clean, and soft cloth. Periodically lubricate all joints and
moving parts with a long lasting lubrication oil.Apply as needed.
2. When not in use, the Pump Unit should be stored with the Release Valve open and the Pump Piston
fully retracted.

18
3. Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe
with a soft non-abrasive clean cloth.
4. A coating of light lubricating oil to pivot points.Axles and hinges will help to prevent rust.
When not in use, store the press in a dry location with ram and pump piston fully retracted.
Periodically check the rams for signs of rust or corrosion. Clean as needed and wipe with a soft
non-abrasive clean cloth.
