Machine type(s)

• The machinery described is intended for machinery production and assembling spare parts. It is used to press, size, assemble, rivet small parts in process No other use permitted. For professional use only.
• Please read the instructions carefully before starting the machine.

Mounting instruction

Make sure every parts are fixed and tightened.

• Attach the base section to the frame (Fig.03) and support to left and right connecting plate. (Fig. 04)
• Assemble the nylon ring to gauge fitting, then put the pressure gauge and twist tight. (Fig. 05/06)
• Remark: twist as tight as possible, otherwise it will be leak. Attach the gauge fitting to the suitable upper cross beam and twist bolt.
• Assemble pump to the frame and hose kit to the pump Fig. 07 (WP15), Fig. 09 (WP20S), Fig. 11 (WP30P & WP50P).
• Insert the complete handle into the opening of the lever support.
• During moving the machine, make sure to use the proper lifting equipment and follow the instructions in document 8940174875
• Main structures of PRESS include Pin, Feet, V-Block, Table, Frame. (Fig. 02)
• Caution Working area of 1 m must be kept free both in front of and behind the machine while it is in operation so that it is always easily accessible (Fig.12)
• Be careful then use the PRESS, SAFETY INSTRUCTIONS in document 8940174875 .(Fig.14) Purge air from the hydraulic system:
• Open the air valve by turning it counterclockwise and purge the air bleed valve
• Pump several full stokes to eliminate any air in the system.

Operation

• Caution Ensure table at proper position and lock the table by 4 pins firmly. (Fig.15)

• Close the release valve, by turning it clockwise.
  Note : Press has an Automatic 2-speed hydraulic pump, equipped with an automatic valve instead of an control valve.

• Pump the handle/foot pedal until serrated saddle nears workpiece. Align workpiece and ram to ensure center loading.

• Caution A single hand-wheel controls the release valve, the switching between fast and slow speed can be done automatically.

• Pump the handle/foot pedal to apply load onto workpiece (see numeration in pressure gauge).

• When work is done, stop pumping, slowly and carefully remove load from workpiece by turning the release valve counterclockwise in small increments.(must turn with the small angle)

• Once ram has fully retracted, remove workpiece from table.

• The V-block must be used by pair, not by piece!

• Only one person is allowed to operate the press.

• Make sure that the operator must wear protective cloth, gloves, safety helmet, shoes and ear protector during operating.

• To avoid accidents, always be aware of any on-going work on the machine. Also, always stay focused on the job to be done.
