3. ASSEMBLY
Use the exploded drawing as your guide to assemble. Lay all parts and assemblies out in front of you before beginning.
The following procedure is recommended:
3.1 Attach one base section (21) to left post and lower cross member (26) using bolts (25), washers (22), lock washers (23)
and nuts (24), then attach another to right post and the lower cross member.
3.2 Put the press frame in an upright position, attach one upper cross beam (10) to left and right posts (20) using bolts (9), washers
(13), lock washers (12) and nuts (11).
3.3 Put another upper crossbeam into position and insert the under plate (7) to the two upper cross beams at the same time, then
secure this cross beam to the posts using bolts (9), washers (13), lock washers (12) and nuts (11).
3.4 Screw the upper round nut (6) onto the ram (3), insert the ram into the hole in the under plate (7), then screw the under round
nut (8) onto the ram and attach the serrated saddle (5) to the ram.
3.5 Join the two press bed frame (18) together by inserting the four bolts (27) through the bushings (28) and the holes in the bed
frames, then secure the four bolts by tighten the washer (14), lock washer (15) and nut (16) on it.
3.6 Insert bed frame pin (19) into the holes in the posts, then insert the joined press bed frame (18) into press frame and onto
bed frame pin.
3.7 Attach the setting plate (31)to the right post using bolts (25), washers (22), lock washers (23) and nuts (24), then secure
the pump assemblies using the screws (29)and washers (30), and then insert the handle to the handle bracket.
3.8 Connect the hydraulic hose coupler (P17) to the connection nut (R15)and assemble the pressure gauge (1) to the pressure
gauge connection nut (R13) which is on the top of ram (3).
3.9 Tighten all bolts and screws.
4. BEFORE FIRST USE
4.1 Note: Before first use of this product, purge away air from the hydraulic system: open the release valve by turning it

5. OPERATING INSTRUCTIONS
WARNING! Ensure that you read, understand and apply the safety instructions and warnings before use.
5.1 Place the heel block (17) on press bed frame (18), then insert workpiece onto the heel block.
5.2 Close the release valve by turning it clockwise until it is firmly closed.
5.3 Pump the handle until serrated saddle nears workpiece.
5.4 Align workpiece and ram to ensure center-loading.
5.5 Pump the handle to apply load onto workpiece.
5.6 When work is done, stop pumping the handle, slowly and carefully remove load from workpiece by turning the release
valve counterclockwise in small increments.
5.7 Once the ram has fully retracted, remove workpiece from bed frame.
6. MAINTENANCE
6.1 Clean the outside of the press with dry, clean and soft cloth and periodically lubricate the joints and all moving parts with a
light oil as needed.
6.2 When not in use, store the press in a dry location with ram and piston fully retracted.
