ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Safety is a primary concern in the design and manufacture of our products. Unfortunately, our eorts to provide safe equipment can
be erased by an operator’s single careless act. In addition, hazard control and accident prevention are dependent upon the awareness,
concern, judgment, and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.
Make certain that the operator(s), prior to operating is instructed in safe and proper use and reviews and understands the manual(s)
pertaining to this machine. Read this manual before you operate this machine. If you do not understand any part of this manual, or need
more information, contact the manufacturer or your authorized dealer.
SAFETY
Understand that your safety and the safety of other persons is measured by how you service, and operate this machine. Know the positions
and functions of all controls before you try to operate them. Make sure to check all controls in a safe area before starting your work.
The safety information given in this manual does not replace safety codes, federal, state or local laws. Make certain your machine has the
proper equipment as designated by local laws and regulations.
Keep all safety shields in place.
Keep hands, feet, hair and clothing away from moving parts while unit is in operation.
Ensure that everyone is clear of equipment before operating the jack.
Avoid high pressure uids. Escaping uid under pressure can penetrate the skin causing serious injury. Always relieve pressure before
disconnecting hydraulic lines. Wear proper hand and eye protection when searching for leaks. Use wood or cardboard instead of hands.
Keep all components in good repair.
