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 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
unbinding; 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 ram.
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. Always store jack in the fully
retracted postion when stored in outdoor or
caustic enviroments that can cause corrosion
and/or rust.
