INSTRUCTION & REPAIR PARTS SHEET
IMPORTANT RECEIVING INSTRUCTIONS:
Visually inspect all components for shipping damage. Shipping
damage is not covered by warranty. If shipping damage is found
notify the carrier at once. The carrier is responsible for all repair
and replacement costs resulting from damage in shipment.
READ CAREFULLY! SAVE THESE INSTRUCTIONS FOR
FUTURE USE.
SAFETY FIRST:
It is impossible to predict the exact force needed for every
pulling situation. The amount of press-t and force of removal
can vary greatly between jobs. The set-up requirements along
with the size, shape and condition of the parts being pulled
are all variables which must be considered. Remember that a
signicant amount of force can be exerted with a puller. Respect
this force and always observe safety precautions. Failure to
comply with the following cautions and warnings could cause
equipment damage or personal injury.
!
WARNING: DO NOT touch or handle hydraulic hoses or
ttings with pressure in the system. Escaping oil under
pressure may cause serious injury. If oil is injected under the
skin see a doctor immediately.
DO NOT make any electrical adjustments with electrical power
active in the system.
DO NOT make or break any hydraulic connections with pressure
in the system.
DO NOT overload the equipment. Use the right size puller.
DO NOT stand on, under or near the puller while in use. Keep
hands, feet and clothing away from moving parts.
To avoid personal injury and equipment damage, make sure
all hydraulic components withstand the maximum hydraulic
pressure of 10,000 psi [700 bar].
Make sure all system components are protected from external
sources of damage, such as excessive heat, ame, moving
machine parts, sharp edges and corrosive chemicals.
Always check to ensure that all cylinders and components are
securely fastened.
!
IMPORTANT: Inspect puller for dents, cracks, or
excessive wear before each use. Immediately replace
worn or damaged parts.
Cover application with a protective blanket before applying
force. Since high force is applied on the part being pulled,
breakage may occur and user may be exposed to ying debris.
Use hydraulic gauges in each hydraulic system to indicate safe
operating loads.
Apply force gradually. Be sure the puller is square with the
component to be pulled.
Wear safety glasses or other approved eye protection.
Keep hands away from possible pinching points.
Always make sure the puller is aligned with the shaft.
Select the appropriate pushing adaptor for each application
(refer to page 4).
Always place the puller in the lowest position and remove
pushing adaptors while transporting.
Keep slide rollers and mast clean and lubricated.
Always keep puller hoist vertical and the control valve closed
when not adjusting vertical position.
A small amount of oil seepage is normal from breather vent on
hoist cylinder.
Use only genuine Enerpac parts and endorsed hydraulic
components.
!
CAUTION: Make sure that all items being pulled are
supported by a means other than the puller. When
using a puller in excess of 50 pounds [19 kg], support puller by
other means than a single person. Do not use the puller for
lifting or supporting objects.
Avoid sharp bends and kinks in hoses as they may lead to
premature hose failure. Inspect hoses and ttings for leaks or
damaged areas. Immediately discard and replace damaged
components.

Pushing Adaptors | Jaw Tips
Pushing Adaptors:
Included with the EPH Series pullers are 3 pushing adapters and a coupler. Connect two pushing adaptors together
to increase the reach of the ram. Using a variety of combinations may be necessary to complete the pull of a deeply
set gear or bearing.

ADJUSTMENTS:
RAISING THE PULLER:
1. Place cylinder control valve lever in “Hoist Oil Supply”position.
2. Raise puller by placing remote jog switch in“On” position and opening the puller hoist vertical control valve.
3. Release remote jog switch. Close vertical control valve after reaching desired height.
LOWERING THE PULLER:
1. Place cylinder control valve lever in “Hoist Lower” position.
2. Lower puller by turning puller hoist vertical control valve counterclockwise.
3. Close vertical control valve after reaching desired height.
NOTE:
HOIST TRAVEL SPEED:
The restrictor valve, located at the top of the hoist cylinder, is used to control the rate of puller descent. This valve should be set at
the desired rate and locked in place using the nut on the valve shaft.
An appropriate starting point is one full turn from the closed position. This valve is a one-way restrictor only and does not aect
the rate at which the puller is raised.

Assembly | Adjustments
ASSEMBLY:
1. Ensure that shipping crate rmly rests on level ground in upright position.
2. Open small side panel and conrm that puller is resting rmly in upright position in the crate.
3. Remove remainder of plywood.
4. Inspect puller for any damage that may have been caused by shipping.
5. Save bolts that were used to brace the cart. These will be used for securing the included cart wheels to the cart.
6. Inspect hoses for proper ratings. Connect the 10,000 psi [700 bar] hose to the port marked “10,000 psi only” on the puller and
the pressurized port on the pump. Connect hose with the lower pressure rating to the return port on puller and pump.
7. Check oil level in pump reservoir. Add oil if oil level is low. Use only Enerpac oil. See pump manual for instructions.

OUT to increase spread.
CHANGING THE JAW SPREAD:
If opening/closing the jaws using the standard cage setting does not provide enough spread or does not provide enough closure,
use the following adjustments to achieve the maximum and minimum spreads.
1. Support the jaws.
2. Remove 6 cap screws, lock washers and nuts on 1 jaw guide at a time.
3. Slide jaw guide inward/outward on cage 1 bolt hole.
4. Replace 4 cap screws, lock washer, and nuts and tighten appropriately.
5. Reverse this process to return to standard jaw spread.

ADJUSTING SLIDE ROLLERS:
1. Lower slide and puller assembly until it rests solidly on base.
2. Loosen 5/8”hex bolt.
3. Move roller using eye bolts on each side of roller.
4. Adjust roller until equal spacing is obtained between mast and slide tube on both roller side and opposite side.
5. Tighten locking nut on eye bolt.
6. Tighten 5/8”hex bolt.
ADJUSTING JAW TIPS:
Adjust jaw tips by turning 1 ¼” cap screw.
NOTE: Always use maximum pulling surface of jaw. To angle tip inward, turn cap screw clockwise. To angle tip outward, turn cap
screw counterclockwise. Before pulling, always make certain machined caps are properly tted to curved surface.

REMOVING PULLER FROM THE CART:
1. Support puller weight using lifting brackets provided.
2. Close puller hoist vertical control valve.
3. Disconnect puller hoist hose coupler at control panel.
4. Remove 2 of the ½”bolts which fasten locking plate to the puller lift bracket.
5. Remove puller from cart by rotating cart while keeping puller stationary.

Set-up | Pulling an object
SET-UP:
1. Transport the puller by use of the puller cart or forklift.
2. Line the puller up to the workpiece.
3. Open the jaws.
OPENING THE JAWS:
I. Place cylinder control valve lever in “Oil Supply” position.

position to close jaws to the desired spread or for clamping.
EXTENDING CYLINDER:
I. Place cylinder control valve in“Extend” position.
II. Activate pump with jog switch.
7. Adjust the jaw tips appropriately. See ADJUSTING JAW TIPS on page 6.
4. Position the workpiece to be removed in between the jaws.
5. Continue to adjust the height until the workpiece and extending cylinder are aligned. See RAISING THE PULLER on page 5.
6. Close the jaws.
PULLING AN OBJECT:
1. Extend the cylinder ram towards the workpiece until there is contact.
2. Continue to extend the ram. The workpiece will begin to move gradually o the shaft.
3. Retract the cylinder.
4. Completely remove the workpiece.
