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 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.
