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 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 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 ram. 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.

TO ADD OIL:
The hydraulic cylinder assembly contains hydraulic fluid that must be kept at approximately
80% full at all times for proper operation. To check the oil level and to fill remove oil filler
Plug
1.Fully retract the hydraulic ram. 4.Screw the oil plug.
2.Unscrew the oil plug.
3.Fill the oil case.
KEEP DIRT AND OTHER MATERIAL
CLEAR WHEN POURING.
5.Perform the Air Purge Procedure.
Discharge air procedure:
After the oil is added, turn tight the release valve,
manually or use air pump to push the piston out 3”~4”,
loose the release valve, retract the piston, follow the
same procedure for 2 to 3 times, to make sure the oil is
filled completely without air inside
