ASSEMBLY

1. Attach the Bottle Jack to the Frame using two Hex Bolt (M10*25); (Notes: MR8080 can skip this step)
2. Place the Bending Die on the head of the Jack. SYSTEM AIR PURGE: Before operating your Pipe Bender, be sure there is no air trapped in the hydraulic system.
3. Fully lift up the ram of the jack using the handle.
4. Open the Release Valve on the jack by turning it counterclockwise.
5. Push down on the Ram until it goes all the way back into the jack. This should push all air out of the system.
6. Continue pushing down on the top of the ram while closing the Release Valve.
7. Repeat if necessary.

OPERATION

Read the entire Important Safety Information section at the beginning of this manual including all text under subheadings therein before set up or use of product.

Inspect tool before use, looking for damaged, loose, and missing parts. If any problems are found, do not use tool until repaired.

Bleeding the Bottle Jack:

IMPORTANT! Before first use, check for proper hydraulic oil level in the Jack. Then thoroughly test the Jack for proper operation prior to its actual use. If the Jack does not work properly, bleed excess air from its hydraulic system as follows:

1. Open the Release Valve.
2. Remove the Oil Filler Plug and fill the Jack with hydraulic fluid to full level.
3. Apply pressure to the Saddle, and pump the Handle quickly several times.
4. Check the Oil Fill Hole and, if necessary, top off the Oil Fill Hole with oil.
5. Replace the Oil Fill Plug and close the Release Valve.
6. Test the Jack several times for proper operation before putting into use. If after bleeding, the Jack still does not appear to be working properly, do not use until it has been repaired by a qualified service technician.

Tool Set Up:

Note: The Pipe Bender is designed to bend water pipe and heavy galvanized pipe.

When bending conduit or thin walled pipe, you may experience problems with kinks or creases.

To help limit the problem, fill the pipe with sand and cap both ends before bending.

1. Always use this Pipe Bender with the Jack in its upright position. Make sure that there is room on all sides of the Pipe Bender for the length you intend to bend.
2. Place the unit on a solid, flat, level surface capable of supporting the weight of the Pipe Bender, pipes, and all other tools and accessories. The Pipe Bender must always be clamped or bolted down to the workbench when used with a workbench.
3. Select the Bending Die that matches the size of pipe you wish to bend. Each Die is stamped with the pipe size. Place the selected bending die onto the Bottle Jack.
4. The Rollers need to be adjusted so that the top of the pipe to be bent rests against the bottom of the Rollers. Pipe can be bent from a slight curve up to a 90-degree angle, depending on the position of the Rollers and the level of the Bottle Jack Saddle before operation. To adjust the Rollers: a. Remove the R-Pins from the two Roller Bars and slide the Roller Bars out of the Rollers, and remove the Rollers from the Frame.

b. Place the pipe to be bent on the Die and note the holes in the Frame where you need to place the Rollers so the top of the pipe will rest against the bottom of the Rollers. c. Remove the pipe.

d. Hold one of the Rollers over the chosen hole and slide a Roller Bar through the hole in the front of the Frame, the Roller, and the hole in the back of the Frame. e. Lock in place with an R-Pin.

f. Repeat steps d. and e. with the remaining Roller, Roller Bar, and R-Pin.

General Operating Instructions:

1. Slide the pipe you wish to bend through the Pipe Bender, between the Rollers. Note: You may wish to first practice using the Pipe Bender on scrap material.
2. Using the slotted end of the Handle, tighten (clockwise) the Release Valve on the Bottle Jack.
3. Insert the Handle into the Pump Sleeve and pump it up and down to raise the Bottle Jack and bend the pipe.
4. When the pipe has been bent to the desired angle, remove the Handle from the Bottle Jack and use it to loosen (turn counter-clockwise) the Valve Release. Setup up to one full turn. This will release the pipe from the Pipe Bender and allow you to carefully remove it.

MAINTENANCE

1. Before each use, inspect the general condition of the Pipe Bender. Check for broken, cracked, or bent parts, loose or missing parts, and any condition that may affect the proper operation of the product. If a problem occurs, have the product repaired by a qualified technician.

Corrected before further use. Do not use damaged equipment.

1. Before each use, thoroughly test the Bottle Jack for proper operation prior to actual use. If the Bottle Jack appears not to be working properly, follow the Bleer instructions.
2. Change the hydraulic oil at least once every three years. To change the hydraulic oil:

a. With the Jack fully lowered, remove the Oil Filler Plug.

b. Tip the Pipe Bender to allow the old hydraulic oil to drain out of the Housing completely, and dispose of the old hydraulic oil in accordance with local regulations.

c. Completely fill the Housing with a high quality hydraulic jack oil (not including until the oil just begins to run out of the Oil Fill Hole). d. Then, reinstall the Plug.

1. Clean with a clean cloth using a detergent or mild solvent and wipe dry. Store the Pipe Bender in a safe, dry location, in an upright position, out of reach of children and other non-authorized people.
