IMPORTANT SAFETY INFORMATION
Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in serious injury.
Save all warnings and instructions for future reference.
The warnings and precautions discussed in this manual cannot cover all possible conditions and
situations that may occur. It must be understood by the operator that common sense and caution
are factors which cannot be built into this product, but must be supplied by the operator.
Work area
1. Turn off the engine, set the parking brake, and
chock the tires before working on a vehicle.
2. Keep the work area clean and well
lighted. Cluttered benches and dark areas
increase the risk of injury to persons.
3. Keep bystanders and children away
while operating the tool. Distractions can
result in loss of control of the tool.
Personal safety
1. Stay alert. Watch what you are doing and
use common sense when operating the tool.
Do not use the tool while tired or under the
influence of drugs, alcohol, or medication.
A moment of inattention while operating the
tool increases the risk of injury to persons.
2. Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep hair, clothing, and
gloves away from moving parts. Loose clothes,
jewelry, or long hair increases the risk of injury to
persons as a result of being caught in moving parts.
3. Use safety equipment. Wear ANSI-approved safety
goggles and heavy-duty work gloves during use.
Tool use and care
1. Do not force the tool. Use the correct tool for the
application. The correct tool will do the job better
and safer at the rate for which the tool is designed.
2. Store the tool when it is idle out of reach of
children and other untrained persons. A tool
is dangerous in the hands of untrained users.
3. Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that affects the tool’s operation. If damaged,
have the tool serviced before using. Many
accidents are caused by poorly maintained tools.
4. Use only accessories that are identified
by the manufacturer for the specific
tool model. Use of an accessory not
intended for use with the specific tool model,
increases the risk of injury to persons.
5. Avoid off-center loads. If the Pump seems
unusually hard to operate, immediately
stop. Adjust the Ram to eliminate or
diminish an off-center load. The Ram
Toe and Plunger Toe must only be used
together to prevent an off-center load.
6. Protect the Hose. Do not drop heavy
objects on the Hose. Avoid kinks in the
Hose. Maintain proper clearance to avoid
damage to the Hose and Couplers.
7. Inspect repair before using vehicle.
Repairs to structural or frame members
must be inspected by a qualified technician
to ensure that the structure is still strong
enough to safely fulfill its function.
Service
1. Tool service must be performed only
by qualified repair personnel.
2. When servicing a tool, use only identical
replacement parts. Use only authorized parts.
SAVE THESE INSTRUCTIONS.

NOTICE: To prevent damage, do not overextend the Ram.
Ram Attachments
1. The Extension Tubes connect in different
combinations to reach desired lengths.
2. The Connector Pin is used to connect the
female end of the Ram to a Base.
3. The Flat Base is used on the stationary side
to spread out the force of the Ram.
4. The V Base is used to spread out
force on curved surfaces.
5. The Serrated Saddle is used on the
pushing end to prevent slipping.
6. The Rubber Head is used for popping dents out
of sheet metal such as doors or body panels
and to minimize damage to the work surface.
7. The Wedge Head is used to repair small dents
and areas located in angles and tight spaces.
8. The Ram Toe and Plunger Toe are used together to
allow spreading in areas that the Ram cannot fit into.
Note: The Ram Toe and Plunger Toe must only
be used together to prevent an off-center load.
Ram Setup
Note: When positioning the Ram use a smaller
attachment on the side that is to be bent instead
of the stationary side. If the stationary side is in
danger of being bent or damaged, place a block
of wood or other material behind the Flat Base
to distribute pressure over a greater area.
1. Unscrew the End Plugs located on the end of
the Hose and Ram. Clean the end of the Hose
and the inlet on the Ram with a clean cloth.
2. Attach the Hose to the Ram.

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 this product.
WARNING! TO PREVENT SERIOUS INJURY: Keep hands away from contact
areas and tight spaces. The tool may slip and cause injury.
NOTICE: To prevent damage, do not overextend the Ram.
1. IMPORTANT! Check the Hydraulic Fluid
level, following the instructions in the
Cleaning and Maintenance section.
2. Remove any obstructions that could
be damaged or are in the way.
3. Check that the Pressure Gauge is functioning
properly. The Gauge will help ensure that the
system is not under load when disconnecting
hoses or equipment, as well as estimate
the force being placed on the Rams.
Using Ram
1. Position the Ram so that the Base is resting against
a frame member opposite the damaged area. It
must also be in line with the direction in which the
damaged area needs to be pushed. The vehicle
body part must be stronger than the area to be
bent or it may be damaged. A block of wood or
a towel may be used to protect the body part.
2. Aim the pushing end towards the area
that needs to be repaired, and slowly
apply pressure with the Pump.
3. When the damaged area has been bent to the
desired position, slowly turn the Relief Valve
counterclockwise to release the hydraulic
pressure and remove the Ram or Spreader.
Relief
Valve
4. Clean all hydraulic ports and cover
them with clean End Plugs.
Using Spreader
1. Place the Spreader so that the hinged (pushing)
jaw is resting against the part to be moved and the
stationary jaw is resting against a non-movable base.
2. Carefully hold the Spreader in position
and apply pressure with the Pump.
3. Once both ends have made contact, move
as far away as possible and continue to
slowly apply pressure to the damaged area
until the desired bend has been made.
4. When the damaged area has been bent to the
desired position, slowly turn the Relief Valve
counterclockwise to release the hydraulic
pressure and remove the Ram or Spreader.
