Bear Hug™PE Squeeze Tool System
Manual Hydraulic Pump PESMPA #04329 Operator’s Manual
1120-54339
Manual Hydraulic Pump PESMPA is used in conjunction with
PES8BT Base Tool. Read and follow #54343 instructions for
the PES8BT also.
PUMP INFORMATION
• The manual hydraulic pump PESMPA is a 2-stage hand pump
that provides high volume at low pressure (less than 1400 psi)
and low volume at high pressure. The operator will feel handle
resistance around 1400 psi, followed by a sudden release of
resistance.
• The PESMPA has a 3-position pump valve. The positions
are Release, Neutral, and Squeeze. The neutral position holds
hydraulic pressure.
• The PESMPA has an internal pressure relief valve that will
exhaust oil back into the reservoir beyond 10,000 psi.
• The PESMPA has a reservoir cap at the rear that is used for
relling the reservoir. The reservoir cap must be cracked open
in order to bleed the system.
• Maintain the PESMPA with a medium grade (AW46)* hydraulic
uid as needed. Oil reservoir should be ½ - ¾ full, with the tool
in the fully closed position.
SQUEEZE PROCEDURE:
WARNING:
• Avoid binding the tool. Keep the squeeze bars parallel to each
other to avoid tool damage.
• Do not build pressure in the release mode. If pressure or
pumping effort builds, stop pumping immediately and relieve
excess pressure.
PART 1: SQUEEZING PE PIPE
1. Connect pump couplers to the tool.
Hand thread until the gap
between mating couplers is closed.
2. Adjust pump lever to the release
position.
3. Pump using the handle until the tool
is open sufciently for the pipe.
Do not overextend.
4. Follow your company policy concern-
ing static electric discharge at this stage of the procedure.
NOTE: Reed strongly recom-
mends use of the PEGR7 Static
Grounding Device #04621 with
PE Squeeze Tools. The threaded
connection for the PEGR7 on the
PES8BT tool is on the top squeeze
bar. Use a grounding accessory
as a precaution against static
build-up. Dissipate the charge and
minimize the possibility of ignition.
Additional information on static electricity is available in the PPI
Handbook of Polyethylene Pipe 2nd Edition.
5. Remove latch pin and swing out bottom squeeze bar.
6. Mount the tool onto the pipe. Slightly lift latch end of bottom
squeeze bar and close; insert latch pin.
CAUTION: Center the pipe along the width of the bars and
square the pipe relative to the cylinder rods.

7. Select both pipe stops based on pipe diameter and SDR.
Position both pipe stops so that the corresponding at
is facing the bottom squeeze bar. Stops must match one
another.
8. Adjust the pump lever to the squeeze position. Pump
using handle to raise pressure. As the squeeze bars move
closer together and the 4 saddle bolts begin to rise,
continually hand thread in the saddle bolts. Recommended
squeeze rate to avoid pipe damage is 2.0 inches/min.
Pump until pipe stops are contacted or 10,000 psig is
reached. If 10,000 psig is reached wait for the pipe to relax
(10-15 min.) and pump back up to pressure.
CAUTION: Stop pumping when pipe stops contact bottom
squeeze bar, further pumping will cause tool damage.
NOTE: Pipe stops don’t need to contact bottom squeeze bar in
order to satisfactorily control ow.
9. IMPORTANT: Ensure all
4 saddle bolts are hand
tight and the saddle
bolt heads are in contact
with the top saddle
clamps.
PART 2: DISCONNECTING
HYDRAULICS DURING
SQUEEZE (optional)
1. Quickly adjust the pump
valve to the neutral position.
NOTE: Adjusting the pump lever under pressure may take
more effort – this is normal.
2. Slowly move the pump valve to the squeeze position, until all
pressure is on the saddle bolts. Pressure gauge should read
zero (0).
3. The hydraulics can now be disconnected.

This stop position (at bottom) is set to squeeze 6” 15.5 DR
pipe. Stops on both sides of tool must match for proper use.
And, desired setting must be in this bottom orientation.
PART 3: RELEASING PE PIPE
1. Reconnect hydraulics and adjust the pump lever to the
squeeze position. Pump to raise pressure until the saddle
bolts are loose enough to rotate.
2. IMPORTANT: Loosen and fully disengage threads on the
4 saddle bolts before releasing pipe.
3. Quickly adjust the pump valve to the neutral position.
NOTE: Adjusting the pump lever under pressure may take
more effort – this is normal.
4. Slowly and carefully move the pump valve to the release
position, while carefully watching the squeeze bars for
movement. Move lever back to neutral as necessary to
maintain desired release rate. The recommended release rate
to avoid pipe damage is 0.5 inches/min.
5. When the squeeze bars no longer open due to pipe pressure,
move the pump lever to the release position. Pump until there
is enough room around the pipe to remove the tool.
6. Remove the latch pin and swing bottom squeeze bar clear of
the pipe. Remove the tool from the pipe.
PART 4: CARE AND MAINTENANCE
1. Wipe down and clean the tool.
2. Store in a dry place with tool in the closed position.
