Maintenance
Monthly maintenance is recommended. Lubrication is critical to jacks as they support heavy loads. Any restriction due to dirt, rust,etc.,can cause either
slow movement or cause extremely rapid jerks,damaging the internal components.The following steps are designed to keep the jack well lubricated:
1. Lubricate the ram,linkages,saddle and pump mechanism with light oil. Grease wheel bearings and axles.
2. Visually inspect for cracked welds,bent,loose,missing parts or hydraulic oil leaks.
3. If jack is subjected to abnormal load or shock,remove from service and have it examined by a customer service representative prior to use.
4. Clean all surfaces and maintain all labels and warnings.
5. Check and maintain the ram oil level.
6. Check ram every 3 months for any sign of rust or corrosion. Clean as needed and wipe with an oil cloth. When not in use, always leave the saddle and ram all
the way down. Always store your jack in the fully lowered position. this will help protect criti al areas from excessive corrosion. Do not use brake or transmission
fluids or egular motor oil as they can damage the seals.Always purchase and use products labeled Hydraulic Jack Oil.

Maintenance Instructions
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 or 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.
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 spr ay.
-Use a good lubricant on all moving parts.
-For light duty applications, use lubrication once a month.
-For heavy and constant application, weekly lubrication is recommended.
-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.
How the Long Ram Operates
With release valve closed, an upward stroke of the long ram 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 long ram handle releases oil into the cylinder, which forces the ram out. This raises
the hydraulic 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 long ram. Opening the release valve allows oil to flow back into reservoir. This releases hydraulic pressure on the ram, which results
in lowering the hydraulic ram.
