The Hydraulic Hand Pump is now ready for use.
Fluid Bag Removal
The Fluid Bag #12 is designed to hold enough hydraulic fluid to push the Piston Assembly #2 just past the end of
the Sealant Barrel #3. As fluid is pumped out of the Fluid Bag #12 it will collapse. Infrequent use or improper
storage of the pump causes the bag to hold the collapsed shape. Keeping the Sealant Barrel #3 full or following
the proper storage instructions helps it retain its normal shape. If the Fluid Bag #12 has collapsed and does not
return to its normal shape after removal, place it in a warm area and let stand for 24 hours. If it still does not
regain its normal shape it will be difficult to refill and should be replaced.
To remove the Fluid Bag #12, follow these instructions:
1. Have a pipe vise ready and a clean area prepared where you can place parts as they are removed.
2. Open By-Pass Valve #7; check the 15,000 PSI Gauge #17B to make sure all internal pressure is relieved
from the system.
3. Remove head assembly (Sealant Barrel Cap #1 and Hydraulic Pump Hose Assembly #17) from Sealant
Barrel #3.
4. Remove the Handle #10 from the Fulcrum Assembly #9 and clean off any contaminants such as sand or
dirt.
5. Place the Handle #10 so it is centered on the Piston Assembly #2 then push the Piston Assembly #2 to
the bottom of the Sealant Barrel #3.
NOTICE: be very careful not to scratch or score the inside of the Sealant Barrel #3.
6. Clean and return the Handle #10 to the Fulcrum Assembly #9.
7. Place the Fluid Bag Barrel #13 into a pipe vise and unscrew the 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.
8. Place a suitable container under the Hydraulic Hand Pump to catch the hydraulic fluid.
9. Remove the Fluid Bag Barrel #13 from the pipe vise and place the Pump Body Assembly #4 into the pipe
vise with the Fluid Bag Barrel #13 down.
CAUTION: be careful not to damage any of the external parts on the Pump Body
Assembly #4 when clamping into the pipe vise.
10. 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.
CAUTION: It is possible for hydraulic fluid to spray out of the Fluid Bag #12 if the bag
is damaged or distorted. USE certified personal protective equipment.
11. Unscrew the Fluid Bag Barrel #13 from the Pump Body #4A using a chain wrench or a pipe wrench and
as it comes loose from the threads hold it in place.
As you unscrew the Fluid Bag Barrel #13 from the Pump Body #4A it is possible the Fluid Bag
#12 will become loose and the hydraulic fluid will pour out through the bleeder screw hole. Check
the position of the catching container.
12. Carefully lower the Fluid Bag Barrel #13 with one hand. The Fluid Bag #12 could remain in its position or
it may slide down as you lower the Fluid Bag Barrel #13. As you lower the Fluid Bag Barrel #13, grab hold
of the Fluid Bag #12 as it gets exposed with the other hand.
13. Hold the Fluid Bag #12 in place and lower the Fluid Bag Barrel #13 completely off and set in your clean
area.
