OPERATION

PRE-OPERATION PROCEDURES

PREPARATION FOR INITIAL USE

Each unit as shipped has no special unpacking or assembly requirements prior to usage. Inspection to assure the unit was not damaged in shipping and does not contain packing debris is all that is required.

CHECK HYDRAULIC POWER SOURCE

1. Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of 7–9 gpm/26–34 lpm for HTMA Type II tools/

EHTMA category D at 2000 psi/105–140 bar.

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

155 bar minimum.

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

CHECK TOOL

1. Make sure the tool contains the correct anvil for the rod size to be driven. Use the 5/8 inch anvil (standard in the model GD50132RF Rod Driver) for 5/8 inch diameter rod. Use the 1 inch anvil (standard in the model GD50133RF Rod Driver) for 3/4 inch to

1 inch diameter rod. Failure to use the correct anvil with the appropriate rod size can result in damage to the tool or personal injury.

2. There should be no signs of leaks.

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

CHECK TRIGGER MECHANISM

1. Check that the trigger operates smoothly and is free to travel between the ON and OFF positions.

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 hose couplers on the rod driver. It is a good practice to connect the return hose first and disconnect it last to minimize or avoid trapped pressure within the rod driver.

3. Observe flow indicators stamped on hose couplers to be sure that oil will flow in the proper direction.

The female coupler is the inlet coupler.

NOTE:

The pressure increase in uncoupled hoses left in the sun may result in making them difficult to connect.

When possible, connect the free ends of operating hoses together.

OPERATING PROCEDURES

1. Observe all safety precautions.

2. Move the hydraulic circuit control valve to the ON position.

3. Place the anvil of the rod driver over the rod to be driven.

4. Ensure adequate down pressure is applied to the rod driver before starting the rod driver. To start the rod driver, press the button on the control valve to the ON position. Adequate down pressure is very important. When you wish to stop the tool, press the button on the control valve to the OFF position.

INLINE CONTROL VALVE OPERATION

The 38632 Inline Control Valve is designed to provide the ON/OFF functions for a hydraulic tool connected to either an OPEN CENTER (OC) hydraulic system or an

CLOSED CENTER (CC) hydraulic system. The valve is to be used with tools which do not have an ON/OFF trigger control. The 38632 Control Valve can be used on hydraulic systems producing up to 10 gpm/38 lpm with a maximum relief valve setting of 2500 psi/172 bar. The valve ports are -8 SAE (3/4-16 thread) O-ring ports.

SETTING FOR OPEN CENTER (OC) OR

CLOSED CENTER (CC)

Set the valve to OC or CC before connecting it to the hydraulic system. To set the valve for open center operation, use a straight blade screw driver to turn the selector screw counter clockwise until it stops. To set the valve for closed center operation, turn the selector screw clockwise until it stops.

WARNING

Be sure you know if you have an OPEN CENTER

(OC) OR CLOSED CENTER (CC) hydraulic system,

DO NOT attempt to install or operate the 38632

Valve until you do. Incorrect installation or operation of the valve can result in seal failures in the tool, cause excessive heat in the hydraulic system, and may damage the tool and hydraulic system.

Understand which type of hydraulic system you are using before installing or operating this valve.

10 ► GD50 User Manual

OPERATION

INSTALLING THE VALVE

Connect the valve to the hydraulic system as shown in

Figure 2.

OPERATING THE VALVE

Connect the valve to the tool using the illustration below as a guide. Make sure the valve spool on the valve is pushed OFF before connecting the valve to the hydraulic system. Make sure the hydraulic system is OFF before connecting the valve to the hydraulic system. Connect the valve to the hydraulic system. Turn ON the hydraulic system. Place the tool to be operated in its operating position. Push the valve spool ON to begin operating the tool. Push the valve spool OFF to stop operating the tool. Turn the hydraulic system OFF before disconnecting the valve.

COLD WEATHER OPERATION

If the rod driver is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluids, fluid temperature should be at or above 50 °F/10 °C (400 ssu/82 centistokes) before use.

TOOL PROTECTION & CARE

NOTICE

In addition to the Safety Precautions found in this manual, observe the following for equipment protection and care.

• Make sure all couplers are wiped clean before connection.

• The hydraulic circuit control valve must be in the

OFF position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to the quick couples and cause overheating of the hydraulic system.

• Always store the tool in a clean dry space, safe from damage or pilferage.

• Make sure the circuit PRESSURE hose (with male quick disconnect) is connected to the IN port. The circuit RETURN hose (with female quick disconnect) is connected to the opposite port. Do not reverse circuit flow. This can cause damage to internal seals.

• Always replace hoses, couplings and other parts with replacement parts recommended by Stanley

Hydraulic Tools. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.

• Do not exceed the rated flow (see Specifications) in this manual for correct flow rate and model number.

Rapid failure of the internal seals may result.

• Always keep critical tool markings, such as warning stickers and tags legible.

• Tool repair should be performed by experienced personnel only.

• Make certain that the recommended relief valves are installed in the pressure side of the system.

• Do not use the tool for applications for which it was not intended.
