Original operating instruction - 2.5 ton aluminium steel service jack
Lubrication
This equipment will not operate safely without proper lubrication. Using the equipment without proper lubri-
cation 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 light penetrating oil or lubricating spray.
- Use a good lubricant on all moving parts.
- For light duty, use lubrication once a month.
- For heavy and constant use, it is recommended to use lubrication 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 plun-
ger 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 the reservoir.
This releases hydraulic pressure on the ram, which results in lowering the saddle.
Storing the Jack
1. Lower the Lifting ram.
2. Place the handle in the upright position.
3. Store in a dry location, preferably 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 the jack in the fully retracted postion when stored in outdoor or caus-
tic environments that can cause corrosion and/or rust.
To add oil in the jack
1. Position the jack on level ground and lower the saddle.
2. Remove the cover plate.
3. Remove the oil plug.
4. Fill the oil tank until oil level is just beneath the lower rim of the oil fill hole.
5. Replace the oil plug.
6. Replace the cover plate and perform the Air Purge Procedure.
