Screw Jacks
1.0 SAFE OPERATING PROCEDURES & SAFETY PRECAUTIONS
CAUTION: Prior to use, the operator should be instructed by a qualified person in the safe and proper use of the jack for the specific
application.
IMPORTANT: Simplex makes no claim that the jacks covered by this document are suitable for any general or particular use and the user
assumes all liability arising therefrom. In addition, to comply with the requirements set forth by ANSI B30.1 Chapters 1-1, 1-2 and 1-3, all
jacks should be examined by a qualified person prior to each use for damage, proper lubrication, and wear.
IMPORTANT: The jack should be operated through one complete travel cycle prior to application of load to verify that all mechanisms
properly function, and the jack is in good working condition.
WARNING: Never exceed the rated capacity or travel of the jack. Select a jack of greater capacity than the estimated load allowing a large
margin of safety.
CAUTION: Never use a jack that is damaged, dirty, improperly lubricated, or malfunctioning. Jacks that fail inspection must be removed
from service until repaired by an authorized service center.
WARNING: Do not lift human cargo. Do not allow personnel on or under the load until lifting is complete and the load is secure with proper
load supports installed in accordance with OSHA safety and health standards. Ensure that supports have been inspected and approved
by a safety engineer or qualified person of authority.
WARNING: Any jack exceeding 40.7 LBS (18.5 Kg) should be positioned or transported by mechanical means using the lift point indicated
on the jack decal.
IMPORTANT: Prior to operating the jack to lower the load, read operating instructions. Operator should perform the lowering process and
follow the procedure above, taking precautions that all personnel and parts of the human body are clear of the load before lowering.
WARNING: Never apply lever force to extend the jack after contact with immovable objects has occurred. Never kick, jump on, stand on,
or straddle the lever bar. Do not strike with a hammer or force the lever in a rocking motion. Such actions create a personal injury hazard,
the jack could become dislodged causing the load to drop, and jack working parts could also become damaged and fail.
WARNING: The capacity and model number is permanently marked on the side of each jack housing and depicts the maximum load to be
sustained by each model. The maximum screw travel is also listed in the table below by jack model and capacity. Do not exceed jack
capacity or travel.
CAUTION: The jack capacity is the rated load that the jack is designed to sustain under controlled conditions. The rated load is the
maximum gravity load to be applied at the load point axial to the jack screw only. Controlled conditions are conditions of application in an
ambient temperature range of -20.25 °f to 140.25 °f, where the jack is evenly supported on a solid foundation, protected against wind, side
loads and other external forces, such as shock loads or vibrations.
CAUTION: As a safety precaution, remove the lever bar from the head after lifting is complete and when jacks are not in operation.
Accidentally striking an unattended lever bar projecting from the jack could dislocate or dislodge the jack causing the load to drop.
Unattended lever bars could present a trip hazard.
