OPERATION

PRE-OPERATION PROCEDURES

CHECK POWER SOURCE

1.Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of 4–9 gpm/15–34 lpm at 950–2000 psi/65–140 bar.

2.Make certain that the hydraulic power source is equipped with a relief valve set to open at 2100– 2250 psi/145–155 bar.

3.Check that the hydraulic circuit matches the tool for open-center (OC) or closed-center (CC) operation.

CHECK THE TOOL

1.Make certain all tool accessories are correctly in- stalled. Failure to install tool accessories properly can result in damage to the tool or personal injury.

2.There should be no signs of leaks.

3.The tool should be clean and dry with all fittings and fasteners tight.

CONNECT HOSES

1.Wipe all hose couplers with a clean lint-free cloth before making connections.

2.Connect the hoses from the hydraulic power source to the tool fittings or quick disconnects. Connect the return hose first and disconnect it last to eliminate or reduce trapped pressure for easier quick-connect fitting attachment.

NOTE:

If uncoupled hoses are left in the sun, pressure in- crease within the hoses can make them difficult to connect. Whenever possible, connect the free ends of hoses together.

3.Observe the flow indicators stamped on the hose couplers to ensure that the flow is in the proper di- rection. The female coupler on the tool’s IN port is the inlet coupler. See illustration in back of this man- ual for tool port identification.

4.Squeeze the drill trigger momentarily. If the drill does not operate, the hoses might be reversed. Verify correct connection of the hoses before continuing.

DETERMINE TOOL MODEL

Open-center or Closed-center Models

Closed-center models have a closed-center decal on the bottom of the handle.

If you are in doubt about the type, test the tool by con- necting it to an open-center circuit with the trigger re- leased. If pressure rises more in the circuit with the trig-

ger released than when the trigger is pulled, the tool is closed-center.

Open-center/Closed-center Selectable Models

The open-center/closed-center selectable model has a decal on the trigger strut to remind you of the knob posi- tions to select.

IMPORTANT

Failure to set this spool correctly can cause a

mismatch with the hydraulic circuit. This can result in rapid tool heating, seal failure, and poor tool performance.

NOTE:

All models have a knurled knob on the spool. This knob cannot be rotated on single-circuit type tools.

CONTROLS

FORWARD/REVERSE

Forward/Reverse rotation is selected by the lever on the left-hand side of the tool, as shown in Figure 2.
