Information:
Repeat Steps 4 through 6 to remove (bleed) air from the rear table lift cylinder (not shown).
Open (CCW) hand pump control knob (11) to completely lower the DPF cleaner table. Close (CW) the hand pump control knob.

(28) Hydraulic Oil Level 51 to 102 mm (2.0 to 4.0 inch)
Check the oil level in the pump reservoir. Remove fill cap (13) located on the end cap of the hand pump. Hydraulic oil level (28) should be 51 to 102 mm (2.0 to 4.0 inch) from the bottom of the fill hole. Add high-grade hydraulic oil, if needed.Note: A clean wire tie can be used as a dipstick to measure the hydraulic oil level in the pump reservoir.Troubleshooting Guide

Symptom Solution
Air dryer desiccant is a pinkish color. 1. Replace or regenerate the desiccant. Refer to ""Maintenance Section"".
Bursting does not occur. 1. Check display screen for error message.
2. Check power connection to burst valve solenoid.
Cabinet doors do not close correctly. 1. Look for damaged door hinges, seals, and latches.
2. Verify that vehicle sensors have been removed from DPF.
Cabinet doors open during burst process. 1. Verify that doors are correctly latched.
2. Look for damage to door latches.
3. Check seals between DPF and adapters.
Clamping force cannot be obtained. 1. Look for hydraulic fluid leaks.
2. Check fluid level in hydraulic pump. Refer to ""Maintenance Section"".
Clamping force does not hold. 1. Upon initial clamping, it is possible for clamp load to drop
689 to 1379 kPa (99.9 to 200.0 psi) within the first minute, due to temperature effects. After reclamping, the drop should be virtually zero.
2. Look for hydraulic fluid leaks.
Display screen is blank. 1. Verify that machine is ON, plugged into an outlet, and power is available to the outlet.
2. Reset circuit breakers located on left side of control cabinet.
DPF does not line up correctly on the table. 1. Verify that correct adapters are being used.
2. Verify DPF is correctly seated on to lower adapter.
DPF is damaged after cleaning process. 1. Check DPFs for damage before cleaning.
2. Look for damage on adapters.
3. Verify that correct cleaning protocol was entered into machine.
DPF is not cleaned. 1. Check orientation of DPF. Refer to ""General Information"" Section.
2. Verify that correct cleaning protocol was entered into machine.
3. Look for other DPF conditions that may prevent successful cleaning.
