MAINTENANCE INSTRUCTION 

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 light penetrating 
oil, lubricating spray. 
-Use a good lubricant on all moving parts. 
-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 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 

-Some models contain grease fittings that will regularly need to be greased 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 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 allows oil to flow back into reservoir. This releases hydraulic pressure on the ram, 
which results in lowering the saddle. 

Storing the Jack 

1. Lower the Lifting Arm. 
2. Place the handle in the upright position. 
3. 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.
