8. Place the Handle #10 so it is centered on the Piston Assembly #2 then push the Piston Assembly #2 up
to the bottom of the Sealant Barrel #3.
NOTICE: be very careful not to scratch or score the inside of the Sealant Barrel #3.
9. Clean and return the Handle #10 to the Fulcrum Assembly #9.
10. Remove Fluid Bag Barrel Cap #14.
Some Hydraulic Hand Pumps are equipped with a set screw in the side of the Fluid Bag Barrel
Cap #14 and it must be backed off or removed before the Fluid Bag Barrel Cap #14 can be
removed.
11. Remove the bleeder cap screw and washer from Fluid Bag #12. Use a 5/8” wrench to secure the Fluid
Bag #12 and an Allen key to remove the bleeder cap screw and washer.
CAUTION: It is possible for hydraulic fluid to leak or spray out of the Fluid Bag #12 if
the bag is damaged or distorted. USE certified personal protective equipment.
12. To be sure the Piston Assembly #2 is in its proper position repeat steps seven (7), eight (8) and nine (9).
CAUTION: If the Piston Assembly #2 moves, hydraulic fluid may leak or squirt out the
top of the Fluid Bag #12.
13. Using a squeeze bottle, add hydraulic fluid very slowly. Work your fingers around the top of the Fluid Bag
#12 to displace any air bubbles inside. Continue until you are satisfied that all of the air bubbles have
escaped. Leave the Hydraulic Hand Pump in this position with the bleeder cap screw removed for 5 to 10
minutes.
If the Fluid Bag #12 is distorted, leave the Hydraulic Hand Pump in this position with the bleeder
cap screw removed over night. If the Fluid Bag #12 does not return to its original shape it will
need to be replaced. See
“Fluid Bag Removal”
on page sixteen (16).
NOTICE: The Fluid Bag #12 is designed to hold just enough hydraulic fluid to move the
Piston Assembly #2 to the end of Sealant Barrel #3. Refilling the Fluid Bag #12 without
the Piston Assembly #2 being pushed all the way in will result in further problems when
reloading with product.
14. Pull back the Stem and Knob #16A to release the Handle #10.
15. Slowly stroke the Handle #10 three (3) to five (5) times to help remove any air that is trapped in the Pump
Body Assembly #4.
The Piston Assembly #2 should not move with the By-Pass Valve #7 open.
16. Repeat steps twelve (12), thirteen (13) and fourteen (14) as many times as required to remove all the air.
17. Connect the Latch Arm #16E to the Stem and Knob #16A.
18. Once Fluid Bag #12 is full, attach the bleeder cap screw and washer to the fluid bag #12. Use a 5/8”
wrench to secure the Fluid Bag #12 and an Allen key to tighten the bleeder cap screw.
19. Remove the Hydraulic Hand Pump from the pipe vise and carefully pour out any hydraulic fluid which may
have entered into the Fluid Bag Barrel #13, into a suitable container.
20. Put Fluid Bag Barrel Cap #14 back onto the Hydraulic Hand Pump and tighten the set screw if equipped.
The Hydraulic Hand Pump can now be reloaded with a bag or stick type product.
See “How to
Load a Hydraulic Hand Pump”
on page six (6).
For cartridge type product, stroke the Handle #10 until the Piston Assembly #2 is level with the
end of Sealant Barrel #3.
21. Attach and tighten the head assembly onto Sealant Barrel #3.
