OPERATING AND SAFETY PROCEDURES AND PRECAUTIONS
Important
: Prior to using jack, read and understand jack operating instructions (A), (B) and (C), detailed at right. Also
read andunderstand and comply with all operating procedures and safety
precautions on page (2) and (3) of this manual.
Reference safety standard publications:
•
Code of Federal Regulations
- Title 29 Occupational Safety
and Health Standards
(Superintendent of Documents, U.S.
Government Printing Office, Washington D.C. 20402)
•
ANSI B30.1 Safety Standards
- Jacks (American Society of
Mechanical Engineers

Jack Operating Instructions:
(
A
) To raise, move reversing lever to the up position. Select the appropriate socket and insert lever bar, make
certain that lever bar engages full depth of the socket. Grip the lever firmly and make up and down strokes
exerting a controlled force. Complete each stroke and assure pawl engagement prior to each stroke reversal.
Caution
: After each down stroke, gradually release the downward force on the lever bar taking care that the
holding pawl has engaged and the lever is free of load prior to completing the upward stroke. Should the lever
bar be released while under load, it will suddenly
“kick up”
, presenting a personal injury hazard.
(
B
) To lower, move the reversing lever to the down position, insert the lever bar as detailed in instruction (A). Grip
the lever firmly and exert a controlled downward force making up and down strokes. Complete each stroke and
assure pawl engagement prior to each stroke reversal.
Caution
: The down stroke releases the retaining pawl
and transfers the load reaction to the lever bar
in the operators hands. The lever must be allowed
to raise slowly by exerting a controlled downward
force throughout the up stroke. Should the
downward force be released before completion of
the up stroke, the lever will suddenly
“kick up”
,
presenting a personal injury hazard.
(
C
) Operating the speed trip (Group 1 Jacks only)
Warning
: Do not operate speed trip to lower load. This
feature is to be used for dropping the rack bar
under no load condition only.
Before Using Trip:
1.
Be certain that the load is properly blocked.
2.
Move reversing lever to down position.
Operate the lever bar per instruction (B) above
and ratchet lower the load onto substantial
load supports. Continue to lower until load point
of jack clears the load.
When jack is no longer under load, then:
3.
To release the rack bar, move the lever bar
to the down position, hold the speed trip lever
down, and gradually push the lever bar upward.
At the point of pawl disengagement, the rack
bar will suddenly drop.
Caution
: Keep all parts of the human body clear of rack bar
action during release.
