Do the following in using the jack:
5.
Assure that the jack is on a firm foundation, evenly and rigidly supported at the base, properly aligned with the
load, and securely seated at both the lifting point and the base so that neither the jack nor the load can slip or
shift.
6.
Assure that the lever bar’s full arc of travel and the surrounding work space are free of all obstructions. Make
sure the operator’s head and body are positioned to one side of the lever bar, and the area is clear of all other
personnel so that a sudden movement of the load, or release of the lever, will not cause the lever to strike any
one if it “kicks up” or “flies out”.
Warning! A sudden shift or release of the load, or release of the hand force on the lever bar, can cause the
lever bar to “ kick up” or “ fly out” with great or even lethal force. Except for hands on the bar, the head and
body must be clear of the lever bar arc of travel. Keep all other personnel positioned away from the load and
the jack working space.
7.
When using the jack to move or lift a load, follow the operating instructions (A) on page 1 and these operating
and safety procedures and precautions. Assure that securely placed and affixed blocking, guys, guides and
other safety constraints are properly installed which follow the load during operation, so as to prevent the load
from failing or shifting, even if the jack should fail or be accidentally dislocated. (To lower follow procedure 10).
Also see above procedure 6 warning.
8.
Keep fingers and other foreign objects clear of the jack’s rack bar and operating mechanisms.
9.
Immediately after lifting, remove the lever bar from the socket and permanently secure the raised load with
fixed retainers and supports. Assure these retainers and supports are installed in accordance with OSHA
standards with inspection and approval by a safety engineer or other qualified person or authority.
OPERATING AND SAFETY PROCEDURES AND PRECAUTIONS
Do the following in using the jack:
10.
Before lowering the load, be sure that all obstructions are removed (and refer also to all operating and safety
procedures and precautions). Assure that securely affixed guys, guides, and other safety constraints are properly
installed which follow the load during operation so as to prevent the load from becoming unstable or shifting,
and be sure that the jack’s rack bar and mechanisms are free from foreign objects. Then with the reversing lever
in the down position, lower the load evenly per operating instruction (B) on page 1. Also see procedure 6
warning.
11.
If more than one jack is used to move, raise or lower a load: Assure that all jacks are of identical type and
properly positioned so that the load will remain evenly distributed during jacking. Assure that all jacks have
reversing levers positioned for the same direction of travel. (Refer also to all operating and safety procedures
and precautions). Follow operating instructions on page 1 and activate all jack levers in unison with slow,
precision coordinated strokes taking care to move the load evenly.
Caution: Uneven load distribution and uneven lifting or lowering can cause a sudden shift of load with conse-
quent overloading of the jack or inability to hold or control the load or lever bar. See procedure 6 warning.
Abide by the following safety rules of things not to do in using the jack:
•
Never
use a jack without a capacity or instruction label.
•
Never
use a jack beyond (or if you do not know) its rated capacity or stated travel.
•
Never
use a jack which appears cracked, worn, bent or otherwise damaged.
•
Never
use a jack with a dirty or rusty mechanism.
•
Never
apply force to extend the jack after stop contact has occurred.
•
Never
continue to lift a load if the jack or the jack’s rack bar, or its lever bar, is visibly deflecting or distorting
under load, or if any misalignment begins to occur between the jack and the load.
•
Never
abruptly release downward force on the lever bar, unless you are sure that the retaining pawl is engaged
and the lever bar is free from load (See cautions under operating instructions A and B on page 1; and also see
procedure 6 warning).
•
Never
kick, jump, stand on, or straddle the lever bar; nor strike the lever bar with a hammer; nor force the lever
bar in a rocking motion; nor use mechanical or other means to increase the force applied to the lever.
•
Never
use an overlength lever bar as lever bar extenders or “cheaters” (see procedure 4). These can cause
dangerous or lethal overload conditions and excessive force or travel of the lever bar through its arc.
