Efficient and safe machine operation depends on the development, implementation and enforcement of a safety program. This program requires,

among other things, the proper selection of point-of-operation guards and safety devices for each particular job or operation and a thorough safety

training program for all machine personnel. This program should include instruction on the proper operation of the machine, instruction on the

point-of-operation guards and safety devices on the machine, and a regularly scheduled inspection and maintenance program.

Rules and procedures covering each aspect of your safety program should be developed and published both in an operator’s safety manual, as

well as in prominent places throughout the plant and on each machine. Some rules or instructions which must be conveyed to your personnel and

incorporated into your program include:

Danger is used to indicate the presence of a hazard which WILL cause SEVERE

personal injury if the warning is ignored.

THIS SAFETY ALERT SYMBOL IDENTIFIES IMPORTANT SAFETY MESSAGES IN THIS MANUAL.

WHEN YOU SEE THIS SYMBOL , BE ALERT TO THE POSSIBILITY OF PERSONAL INJURY, AND

CAREFULLY READ THE MESSAGE THAT FOLLOWS.

A company’s safety program must involve everyone in the company, from top management to operators, since only as a group can any operational

problems be identified and resolved. It is everyone’s responsibility to implement and communicate the information and material contained in catalogs

and instruction manuals to all persons involved in machine operation. If a language barrier or insufficient education would prevent a person from

reading and understanding various literature available, it should be translated, read or interpreted to the person, with assurance that it is understood.

Never place your hands or any part of your body in this machine.

Never operate this machine without proper eye, face and body protection.

Never operate this machine unless you are fully trained, instructed, and you have read the instruction manual.

Never operate this machine if it is not working properly—stop operating and advise your supervisor immediately.

Never use a foot switch to operate this machine unless a point-of-operation guard or device is provided and

properly maintained.

Never operate this machine unless two-hand trip, two-hand control or presence sensing device is installed at the proper

safety distance. Consult your supervisor should you have any questions regarding the proper safety distance.

General Description of Components in the System

A complete control package for hydraulic machines includes the following:

1. Literature folder (see page 14) containing installation manuals, “Operator Safety Precaution” Pamphlet, danger sign(s), electrical control

schematics, and our latest catalog

2. Control box - standard (custom or special includes motor controls and/or disconnect switch) with danger and warning signs

3. Palm button assembly (Includes two black palm buttons, two palm button guards, one red emergency-stop button, and mounting boxes. When

the “automatic” mode of operation is included, one yellow return/inch-up button with mounting box is furnished.) If multiple operator stations

are on a machine, more than one assembly is furnished.

4. Foot switch (optional) - If multiple operator stations are on a machine, more than one foot switch is furnished

5. Supervisory control station (Required when multiple operator stations are used on the machine; one station is required for each operator.)

6. Other required components and safeguarding that may be necessary for machine (See packing list for details.)

Individual packages may vary in contents. However, a packing list is always enclosed showing exactly what material was shipped on this order.

Please check the components actually received against this packing list immediately. In most cases, this control package system includes two-hand

control which can be used as a point-of-operation safeguarding device provided the palm buttons are mounted correctly and at the proper safety

distance (see formula on page 19 of this manual). If the optional foot switch is provided, a safeguard must always be used. Examples of safeguards

include barrier guards, presence sensing devices, pullbacks, restraints, gates, or two-hand control. The hands or any other part of the body of an

operator, maintenance person, setup person, etc., must never be put into the point-of-operation hazard for any reason, at any time.

These controls can neither cure nor overcome a malfunctioning machine. They cannot compensate for or prevent

a mechanical defect or failure of a machine part. These controls cannot prevent a repeat or unintended stroke

(cycle) resulting from a mechanical or hydraulic component malfunction, defect or failure of the machine itself.

Preliminary Steps Before Installation

Before proceeding with the installation of the enclosed equipment, you should undertake the following preliminary steps.

1. Read and make sure you understand this entire Installation Manual.

2. Refer to the front cover, other line drawings and photos, then make a rough sketch of your installation to plan the location of the enclosed

equipment on the machine.

3. This may be an opportunity to strip down the entire machine by removing all components, piping, wire,etc. Clean, paint and check the entire

electrical, hydraulic, and mechanical systems of the machine for proper adjustment and required replacement parts before proceeding with the

installation of the furnished equipment.

4. Please make sure the machine is in first-class condition. Before starting any installation, it is essential that the machine is thoroughly

inspected. Be sure that all mechanical components and all collateral equipment are in first-class operating condition. Your inspection should be

done according to the machine manufacturer’s installation and maintenance instruction manual. If you have any doubts or questions concerning

the condition of the machine, contact the machine manufacturer for assistance. Repair or replace all parts not operating properly before

proceeding.

Inspection and maintenance programs must be established and implemented to keep machines in first-class

condition. Programs must include thorough inspections of each machine on a weekly basis and records kept of

these inspections. Any part of the machine that is worn, damaged or is not operating properly must be replaced

immediately or repaired before the machine is used.

5. Verify that the machine is in first-class condition and operating properly; shut off all power to the machine. All trapped hydraulic pressure must be
