Safety Handbook for Manual-Mechanical and Hydraulic Puller

To avoid personal injury during system operation, read and follow all CAUTIONS, WARNINGS, and INSTRUCTIONS included with or attached to each product. Enerpac cannot be responsible for damage resulting from unsafe use of product, lack of maintenance, or incorrect product and system application.

WARNING: 

Always wear proper personal protective gear (i.e. gloves, safety glasses). - Never use a tool to strike the puller. Hitting the puller may cause it to break.- Make sure that the items to be pulled are supported by a means other than the puller.
  • Applying heat to the puller may damage it, causing the puller to fail at lower than rated load.
  • Before each use, lubricate the center bolt threads with a graphite-based lubricant.
  • Use puller only with recommended attachments or damage to the puller may occur.
  • Use a puller capable of pulling the load. Overloading the puller may cause it to break.
  • NEVER use standard grade bolts or parts to repair pullers. Standard grade parts may break when the puller is used, causing personal injury and/or property damage.

Important: Always keep the guide paths of the lifting plate greased.

Mechanical Puller Operation:

  1. Make sure that the spindle is clean and greased before use.
  2. The shaft (A) must have a center hole (B) as shown. If it does not, use a shaft protector (C). (See Fig. 1)
  3. Tighten strap bolts to hold jaws lightly in place.
  4. Position the puller as shown in Fig 2.
  5. Tighten the spindle slightly by turning the spindle nut.
  6. Check that the jaws are fully contacting the part to be pulled.
  7. Tighten the strap bolts.
  8. Apply pulling force by turning the spindle.

Post Lock Puller Operation Manual Pullers:

  1. Make sure that all items being pulled are supported by a means other than the puller. NO LOOSE PIECES!!!
  2. Before each use, lubricate the center bolt of the puller with a graphite-based lubricant.
  3. To operate the puller, grasp the puller with one hand and turn the T-handle counter-clockwise with the other hand until the jaw opening is big enough to fit over the component to be pulled.
  4. Turn the T-Handle clockwise to tighten the jaw firmly onto the component. (Fig. 3A)
  5. Make sure that the center of the puller is aligned with the center of the component to be pulled. Using hand tools only, tighten the center bolt to pull the component off of its shaft. Never exceed the maximum torque ratings of the puller’s drive bolt. (Fig. 3B)
  6. Turn the T-handle counter-clockwise to remove the puller from the component. (Fig. 3C)

Hydraulic Puller Operation:

  1. Make sure that all items being pulled are supported by a means other than the puller. NO LOOSE PIECES!!!
  2. Install the cylinder into the puller by threading collar threads clock-wise into the jawhead assembly. Make sure that the puller collar threads are fully engaged in the puller. Attach lift plate to the coupler end of the cylinder. Remove the saddle from the cylinder and insert the ram point into the plunger. Select the ram point that will provide the maximum contact with the shaft.
  3. To operate the puller, grasp the puller with one hand and turn the T-handle counter-clockwise with the other hand until the jaw opening is big enough to fit over the component to be pulled.
  4. Turn the T-Handle clockwise to tighten the jaw firmly onto the component.
  5. Make sure that the puller is square with the component to be pulled. Advance the plunger until the ram point contacts the shaft to insure correct alignment. The center point of the puller must be aligned with the center point of the shaft. Continue to advance the plunger slowly to pull the component off of the shaft. Never try to retighten the T-handle during the pulling operation. For 100-ton hydraulic pullers refer to the puller instruction sheet.
