are variables which must be considered. Study each pulling
application before you select your puller.
• Do not overload equip ment. Use the correct size puller for
your application. If you have applied significant force, and
the part still will not move, then use a larger capacity puller.
Use of sledge hammers to assist in removing components
is not recommended.
• Do not overtighten the adjusting rod. Stop tightening if the
adjusting rod bends, or if deformation of the jaws occurs.
• Do not use puller if threads on adjusting rod and/or body are
damaged or worn. Do not use puller if adjusting rod is bent.
• Apply force gradually. Align puller grip jaws as required. Be
sure the setup is rigid and that puller is square with the work.
• Make sure that all puller components are protected from
external sources of damage, such as excessive heat,
flame, moving machine parts, sharp edges and corrosive
chemicals.
• Always perform a visual inspection of the puller before
placing it into operation. If any problems are found, do not
use the puller. Have the equipment repaired and tested
before it is returned to service.
• Never use a puller that is damaged, altered or in need of
repair.
• Always be sure that the adjusting rod is loosened before
performing any puller adjustment or repair procedures. Never
service the puller while it is installed and under tension.
• Always read, understand and follow all safety precautions
and instructions, including those that are contained within
the procedures of this manual.

Failure to observe and comply with the following precaution
could result in minor or moderate personal injury. Property
damage could also occur.
• Immediately replace worn or damaged parts with genuine

4.0 PRODUCT DESCRIPTION
The SGM-Series Sync Grip Puller can be used to remove
gears, bearings, pulleys and other similar shaft mounted parts.
The puller's self centering closing system means that all jaws
move at the same time, reducing the chance of damage to the
puller components and to the item being removed.
Five different puller models are available in rated capacities of
1 to 20 US Tons [8.9 to 177.9 kN]. Refer to the documentation
provided with your shipment for model numbers and additional
product data.
5.0 SETUP AND ASSEMBLY
5.1 Handling Large Pullers
• Use a crane and slings of suitable rated capacity to lift and
unload the puller.
• Know the weight of the complete puller including puller
body, adjusting rod and jaws.
• Be careful when lifting the puller while it is in the vertical
position, as the jaws will close.
• If needed, support and reposition the puller with slings so
that it can be used horizontally. When repositioning the
puller from the horizontal to the vertical position, incline the
puller slowly and carefully.
5.2 Configurations
Models SGM01, SGM04, SGM07 and SGM10 can be
configured as either a two-jaw or three-jaw grip puller. Model
SGM20 can be assembled only in the three-jaw configuration.
See Figure 2 for jaw mounting details.
A three-jaw grip puller provides a more stable and secure grip
than a two-jaw grip puller, resulting in a more even pulling
force. For this reason, the three-jaw configuration should be
used whenever possible.
