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 the 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 hydraulic ram to lowest position.
2. Leave lowering valve open.
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. Always store jack in the fully retracted postion when
stored in outdoor or caustic enviroments that can cause corrosion and/or rust.
