SPECIAL TOOLS

Remove hose from pump port and connect

pressure gauge.

Hydraulic settings must be checked whenever a

component is repaired or replaced.

Remove counterbalance valves and “bench test”

them if they are suspect.

Connect a pressure guage of appropriate range to

the test port located on the hydraulic manifold.

Correct pressure settings are listed in the hydraulic

schematic.

The following is a list of tools which may be required

to perform certain maintenance procedures on the

AB38.

• Flow Meter with Pressure Gauge

(

• 0-207 bar (0-3000 psi) Hydraulic Pressure Guage

with Adapter Fittings (

Snorkel P/N: 014124-030).

• Adapter Fitting (

Snorkel P/N: 063965-002).

• Inclinometer (
