•
Not to be used for aircraft purposes!
•
Do not attempt to move the crane when under load.
The swivel Casters are not designed
to be rolled when the crane is lifting a weight.
Maintenance
•
Check all of the mounting hardware before each use and make sure it is safe to use the
crane.
•
Make sure the hook and chain are clean of dirt, grease or debris.
•
If the jack is not performing to satisfaction, there may be air in the hydraulic system. To purge
the system of the air, follow these instructions:
◦
Make sure the ram is completely lowered.
◦
Remove the oil fill plug and top off with hydraulic fluid.
◦
Raise the ram to maximum height.
◦
Loosen the release valve and push the ram all the way down.
◦
Top off with hydraulic fluid and replace the plug. Repeat if necessary.
•
To clean we recommend to use a damp cloth and mild detergent. Do not use solvents or flam-
mable agents.
•
If lifting performance of the foldable shop crane begins to diminish, check the hydraulic opil
level in the oil tank. If necessary, top off the oil tank with hydraulic oil.
Operation instructions
1.
To raise the extension boom, close the release valve on the hydraulic ram. Pump the handle
until the extension boom reaches the desired height.
2.
To extend the length of the extension boom, remove bolt and nut. Pull out on the extension
boom until the desired extension hole in the boom aligns with the hole in the extension boom.
Then re-insert the bolt through the holes in the boom and extension boom and lock the bolt in
place with the nut.
3.
WARNING! Do not exceed the maximum lifting capacities of this tool.
Exceeding the
maximum lifting capacities could cause personal injury and/or property damage.
The longer
the extension boom is extended, the lower is the lifting capacity of this foldable crane.
4.
Position the foldable crane so that the hook is directly above the object you wish to lift.
5.
WARNING!
Stay clear of the foldable crane. Never go under an object being lifted by the
crane. It is possible for the hook to slip causing an object to fall. This might result in serious in-
jury and/or property damage. Always monitor the object being lifted so it does not rock back
and forth.
6.
Open the release valve slightly to lower the hook. Attach the hook to the object you are lifting
and make sure the safety latch on the hook is fully closed. Then close the release valve and
pump the handle to raise the object. Carefully move the crane to the location where you wish
to lower the object, i.e. an engine stand, proper support, floor surface etc. Then lower the ob-
ject by opening the release valve slightly.
7.
Once the object is fully lowered, disconnect the hook from the object. If not needed anymore,
store the crane (unfolded or folded) in a clean, dry, safe location and out of reach of children
and other unauthorized people.
