ECTION
The FT-20 requires routine checking of the unit and periodic preventative maintenance to ensure safe, trouble-free
operation. No special maintenance is required. The following actions are suggested.
Disconnect the PowerPak from air supply before performing maintenance or repair.
4.1

GENERAL CLEANING

1. Periodically clean the outer surfaces of the FT-20 and equipment used with the FT-20.
2. When not in use, ensure that the dust cap is reinstalled on the hydraulic coupler.
3. Keep all hose connections free of metal chips, dirt, and grime.
4. Keep the breather hole in the vented filler cap and dipstick clean and unobstructed.
5. The hydraulic oil should be replaced every 200 to 500 hours of use, depending on severity of use and
environmental conditions.
6. Always clean the hydraulic and air couplers prior to making connections.
4.2

CHECKING HYDRAULIC FLUID LEVEL

1. Clean the top plate, remove the filler cap and dipstick, and visually check the oil level in the reservoir after
every 40 hours of use.
2. The proper oil level is within 5/16 inch of the top of the reservoir when the puller unit's mandrel is in its normal
starting position (mandrel extended and trigger released). The fill line on the reservoir is 5/16 inch from the
top.
4.3

FILLING HYDRAULIC FLUID RESERVOIR

1. Disconnect the puller unit from the PowerPak and the air supply when adding oil to the reservoir.
2. Clean the entire area around the vented filler cap and dipstick before removing the filler plug located to the right
and slightly behind the hydraulic quick coupler.
3. Remove the filler cap and dipstick. Insert a clean funnel with a flexible tube and strain the new oil through a
paper filter. If a flexible tube is not available, the pump shroud may need to be removed for access.
4. Fill with hydraulic fluid to within 5/16 inch of the top of the filler hole. The fill line on the reservoir is 5/16
inch from the top. See Section 1.3 for hydraulic fluid specifications.
5. Replace the filler cap and dipstick and make sure the breather hole in the filler cap and dipstick is open. Cycle
the PowerPak (with the puller unit attached) several times, and recheck the oil level in the PowerPak reservoir.
