STANLEY HP12B GT & HP Power Unit Technical Bulletin Instruction Manual

STANLEY HP12B GT & HP Power Unit Technical Bulletin Instruction Manual

What has changed?

For all non-diesel models of GT and HP Power Units, a shipping cap will be installed over the breather valve of the hydraulic oil tank.

Caution: Pump damage can occur if action is not taken! Remove the attached shipping cap and tag before using this power unit. Failure to remove the shipping cap could cause catastrophic damage.

Why has the change taken place?
During shipping, it is possible for hydraulic oil to escape the hydraulic oil reservoir through the breather valve. In order to eliminate hydraulic oil spillage, STANLEY will install a cap over the breather valve before the power unit is shipped.

How to Remove the Shipping Cap

1. Unpack the power unit.

2. Locate the shipping cap installed over the breather valve.
   Note: The shipping cap will be connected to a large information tag.
   

3. Grasp the base of the cap, pull it off of the breather valve and discard it.
   Note: If your power unit breather valve does not have a cap installed, you may use the power unit normally

INSTALL HYDRAULIC CONNECTIONS

STANLEY recommends you use hose lengths of 25 ft/8 m with 1/2 inch/12.7 mm inside diameter. Hoses must have a working pressure rating of at least 2500 psi/175 bar. Hose ends must have male threads compatible with H.T.M.A. quick disconnect fittings (NPT).

H.T.M.A. approved quick disconnect couplings are installed to hydraulic hoses so that the direction of oil flow is always from the male to the female coupling. Additional fittings, such as reducers or adapter fittings, are not required.

If adapter fittings are used, they must be approved steel hydraulic fittings meeting a minimum operating pressure rating of 2500 psi/172 bar. Do not use galvanized pipe fittings or black pipe fittings.

Use thread tape or pipe joint compound when installing quick disconnect couplings to hose or tool fittings. Follow the instructions furnished with the selected thread sealant.

DO NOT OVERTIGHTEN THE FITTINGS.

Connect the pressure hose to the bottom (male) fitting.
Connect the return hose to the top (female) fitting.

CONTROLS

HP12 can provide one 8 GPM/30 LPM circuit, one 10 GPM/40 LPM circuit or one 12 GPM/45 LPM circuit.

STARTUP

1. Toggle the Flow Switch to the “FLOW OFF” position.
   Note: HP12 will not start unless the Flow Switch is in the “FLOW OFF” position.

2. Pull the choke knob out

3. Select the desired flow using the Flow Selector Knob.

4. Turn the Ignition Switch to the “START” position. After the engine starts, release the switch.

5. Gradually push in the choke knob as the engine begins to idle smoothly.

6. Allow the engine to warm up.

7. Connect hoses and the tool.

8. Toggle the Flow Switch to the “FLOW ON” position.

CHANGING CIRCUIT FLOW

1. Toggle the Flow Switch to the “FLOW OFF” position
2. Select the desired circuit flow using the Flow Selector Knob.
3. Toggle the Flow Switch to the “FLOW ON” position.

SHUTDOWN

1. Toggle the Flow Switch to the “FLOW OFF” position.
2. Allow the engine to idle for approximately one minute
3. Turn the Ignition Switch to the “OFF” position.

COLD WEATHER STARTUP

Hydraulic fluid becomes thicker in cold weather. STANLEY recommends that the engine be run at a low idle (5 GMP/20 LPM setting) long enough to bring the fluid temperature up to a minimum of 50°F/10°C. Allow the hydraulic fluid to circulate through the tool hoses until they are warm.

Once the hydraulic oil is warm, you may operate the HP12 as normal.

MAINTENANCE & TESTING

ENGINE MAINTENANCE SCHEDULE

Follow the maintenance instructions provided in the engine “Operating & Maintenance Instructions” manual.

HYDRAULIC SYSTEM MAINTENANCE

• Check hydraulic fluid level daily and fill if needed.
• Check hydraulic lines and fittings daily for leaks, kinks or damage. Do not use your hand to perform this check.
• Remove condensed moisture from the hydraulic fluid:
  1. Set the flow selector to a 8 GPM/20 LPM flow.
  2. Start the engine and pump the fluid, out of the male hose fitting, into a 5 gal. container.
  3. When hydraulic tank is empty, turn the Ignition Switch to the “Off” position.
  4. Let the water settle to the bottom of the container.
  5. Pour the hydraulic fluid back into the tank, being careful to not disturb the water sitting at the bottom of the container.
• Change the hydraulic filter every 200 hours of operation. Change more often if used in cold, moist or dusty conditions.
• Check oil cooler. Remove debris with air pressure.

BATTERY

• Do not charge the battery with an automotive battery charger. Charging at higher than 2 amps will damage the battery.
• If the engine stalls during operation, set the ignition switch to the “OFF” position to preserve battery charge.

STORAGE

• Clean the unit thoroughly. Do not pressure wash.
• Always store the unit in a clean and dry location.
• If storing for over 30 days, add an additive to the fuel tank to prevent the fuel from gumming. Run the engine to circulate the additive.
• Replace crankcase oil.

GENERAL

Tests should be performed periodically to ensure HP12 is operating at maximum efficiency. STANLEY Circuit Tester ,part number 04182, can be used to isolate problems in both the engine and hydraulic system.

TESTING THE HYDRAULIC CIRCUIT

Test to ensure the hydraulic pump is supplying the correct flow and pressure, and that the system relief valve is operating properly. Before testing, make sure the engine is warm and operating smoothly.

1. Turn the flow selector switch to the “OFF” position.
2. Set the flow control to the flow you would like to test.
3. Connect the STANLEY Circuit Tester to the tool hoses.
4. Fully open the tester restrictor valve (counterclockwise).
5. Start the engine.
6. The test flow gauge should read +/- 1 GPM of the selected flow.
7. Slowly turn the restrictor valve clockwise while watching the pressure gauge. The flow rate should not change as the pressure reaches 2100-2200 psi/148- 155 bar.
8. At 2100-2200 psi/148-155 bar, the relief valve should begin to open. The flow rate should start to drop because the relief valve is allowing fluid to bypass to the hydraulic fluid tank. The relief valve is preset at the factory. If it does not open within the above range, the relief valve must be reset as follows:
9. a. The relief valve is located on the right side of the unit, behind the dash panel (7). Use a wrench to loosen the nut on the relief valve.
10. b. Use an Allen wrench to adjust the relief valve. Turn clockwise to raise the opening pressure, and counterclockwise to reduce the opening pressure.
11. c. Tighten the nut and test again.
