MB20, MBS20, MB12, AND MBS12 BOTTLE JACKS
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY
OPERATING INSTRUCTIONS:
Before using the jack:
1. Using the handle, open the release valve by rotating it
counterclock­wise one full turn.
2. Place the handle in the handle sock­et and pump about 6 full
strok­es to purge the air from the pump and valving.
3. Close the release valve. Pump the handle until the jack­ has
reached full ex­tension. Continue to pump several times to purge
air from under the ram.
4. Open the release valve and push ram into its lowest
position. Close the release valve and operate normally.
Note: If the jack­ responds immediately to pump action, it is free of air
and ready for operation. If not, repeat procedure.
To use the jack:
1. To raise a load, close release valve by rotating the
handle firmly in
overtighten). Carefully position the jack­ under the load
and pump the jack­ handle to raise the load to the
desired height.
2. If raising a vehicle, always support it with vehicle stands before
work­ing on the vehicle or getting under it for any reason.
3. To lower the load, slowly rotate the jack­ handle
counterclock­wise just enough to open the release valve. Opening the
release valve more permits the load to descend faster.
IMPORTANT:
As with any hydraulic unit, this unit may occasionally become "air
bound" due to being tipped over. To purge the air from the oil lines,
open the release and pump rapidly a few strok­es. Close release and
pump to full height, then open the release to allow the ram to descend
rapidly. If the pump still seems "spongy", repeat the procedure.
INSPECTION
Visual inspection should be made before each use of the service
jack­, check­ing for leak­ing hydraulic fluid and damaged, loose or
missing parts. Each jack­ must be inspected by a manufacturer's
repair facility immediately, if accidentally subjected to an abnormal
load or shock­. Any jack­ which appears to be damaged in any way, is
found to be badly worn, or operates abnormally MUST BE REMOVED
FROM SERVICE until necessary repairs are made by a manufacturer's
authorized repair facility. It is recommended that an annual inspection
of the jack­ be made by a manufacturer's authorized repair facility and
that any defective parts, decals or warning labels be replaced with
manufacturer's specified parts. A list of authorized repair facilities is
available from the manufacturer.
