DESCRIPTION AND SPECIFICATIONS

Pump: Gear, pump rotation is clockwise (motor is CCW). Maximum GPM: 14.1 GPM (53.2L/M) at no load. Flow will decrease as pressure increases. Hydraulic Fluid Tank Capacity: 11 gallons (41.6Liters) Hose Couplings: Bruning quick disconnect, 3/4 inch & ½ inch Relief Pressure: Factory set at 2600 PSI /179.3 Bar (at valve outlet port). Adjustable

to750 PSI, A higher relief setting will stall the engine.

Engine: Honda 21.4 HP (16.0 KW) Net @ 3600RPM, Air-cooled, No load RPM set to 3850. Fuel tank: 4.4 Gal (16.6L).

This unit is compatible with most hydraulically driven sawing and drilling components. The system may not be compatible with components of some manufacturers.

The power unit was inspected and operated before shipment and should not require any additional adjustments prior to its initial use.

Hydraulic Fluid: The reservoir of the hydraulic power unit must be full prior to start-up. The use of high quality petroleum based hydraulic oil with the following properties is recommended:

 Anti-wear  Low foaming  Rust and oxidation inhibitors  Wide temperature range  Fluid viscosity: 8-1000 Centistokes

(52-4600 SUS). The unit is shipped with an ISO 46 Viscosity grade (8Cs/52SUS @ 212F/100C and 46Cs/210SUS @ 104F/40C).

The oil must be kept free of contamination to avoid damage to system components. The strainer in the fill cap must always be in place when adding oil. Quick disconnects must be cleaned before connections are made.

Control Valve: The pressure compensated flow control valve on this unit allows full flow control while the gas engine remains at its most efficient wide-open throttle. This allows a higher operating pressure at all flows. Flow settings are: 0-2, all flow routed to tank; 2-8, adjustable range, 8-10 full flow. Relief pressure can be adjusted by removing the cap at the top of the main

control and using an Allen wrench to adjust the relief cartridge. The relief can be set as low as 750 psi; do not exceed 2600 psi. To adjust, the flow control must be set at 10 and no tool should be attached. This will force all flow over relief. Securely replace the cap as oil seepage will occur through the relief cartridge. The relief is factory set at 2600 psi and should rarely need adjustment.

Hydraulic Oil Cooler and Radiator: The power unit is equipped with a brazed plate style oil cooler. Water should be passed through the cooler before being used for dust control or blade & bit cooling. Some tools will automatically shut off water flow when not actively cutting, drilling, etc. This may result in higher oil temperatures if the power unit continues to run for long periods without cooling water. The optional radiator fan will come on automatically when the oil temperature reaches ~120F. (49C.) and continue to run until the temperature switch cools, even if the engine is shut off. The fan will stop whenever the emergency stop switch is used.

IMPORTANT: If there is a risk of frost

the water must be drained from the cooler to prevent damage by freezing.

HOSES: Large diameters and short

27

lengths are preferred and offer the highest system efficiency. If one is operating 50 ft (15.2M) from the power source, there is also a 50 ft (15.2M) return for a 100 ft (35.5M) total hose length. With 12 GPM and oil at 100 deg. F (37.8C), this could result in a 300 psi (20.6 Bar) pressure loss with ½” hose and a 100 psi (6.9 Bar) loss with 5/8” hose. Pressure loss will change dramatically with oil temperature.

OPERATING INSTRUCTIONS

Operator Responsibilities

It is the operator’s responsibility to use this unit and any attached tools under safe working conditions and to follow proper safety procedures for themselves, coworkers, observers, and the public at large. The operator must be aware of the machine’s capabilities and limitations and follow the safety precautions in each section of this manual. Periodic maintenance is required, in accordance with the instructions herein, to promote safe and reliable operations.

WARNING: Keep bystanders out of the immediate work area.

Wear approved:

 Safety glasses  Ear protection  Hard hat  Gloves  Safety shoes

 Any other protective equipment

required for compliance with standard safety practices or federal, state, and local codes and regulations

Hose Connections: It is best to connect the hoses to the unit before starting as even very low residual pressure can make hose installation more difficult. Push couplings together until you hear it click. Turn locking ring of coupling to the secured position.

Gas Engine:

crankcase is filled with oil to the proper level! Refer to your engine manual for oil checking and changing procedures, along with oil specifications, etc.

IMPORTANT: Operating the engine without oil will ruin the engine.

Fuel: Use regular grade unleaded

gasoline to fuel the engine. Premium grade may be used if necessary. Fill the tank when the engine is off and has been allowed to cool. Care should be taken to prevent spilling fuel. Do not overfill the fuel tank. Always leave enough space for expansion due to environmental heating.

WARNING: In the event of fuel spillage, do not start the engine or operate any nearby electrical component until the spilled fuel has been removed.

Starting Procedure:

 Set the flow control valve to zero.  Open the fuel shut off valve below the

gas tank.

 Be certain the emergency off switch

has been pulled out.

 Set throttle at about 1/3, set choke if

necessary (cold engine). Turn key to start and release. Refer to engine manual for details of control functions.

 Let engine warm and gradually open

the choke and set the throttle to maximum.

DANGER: Exhaust from the gas engine contains carbon monoxide, a poisonous, odorless, invisible gas, which can cause serious illness or death. Do not operate the gas engine where ventilation is restricted. Open windows and doors may not be sufficient to prevent this hazard.

Make sure that the engine

28

Heating Cold Oil: Forcing the oil over relief will quickly increase the oil temperature. With no tool connected to the unit, move the valve setting toward 10. This will force an increasing percentage of oil over relief. Heat cold oil to room temperature or ~100F/38C maximum. Cold oil greatly increases pressure loss in hoses and fittings and may affect tool operation.

Maintaining Oil Temperature: With an ample water supply, it is unlikely overheating will be an issue except in the most extreme ambient temperatures. To force high oil temperatures down, run the unit with the flow control set to zero. This unloads the unit yet circulates oil through the cooling system. The rate of cooling will depend on the ambient temperature and how much water is being passed through the cooler.

Some control valves at the external tool may create backpressure and heat even when off. It is best to set the flow control to zero or shut the power unit down to avoid heating and conserve energy.

IMPORTANT: Monitor the thermometer at the top of the hydraulic tank. Maximum recommended oil temperature is 180 degrees Fahrenheit (82 deg C).

Shutting Down:

 Shift the flow control valve to zero to

unload the system.

 Throttle the engine back to a low RPM.  Turn the key to the off position.

IMPORTANT: The red emergency stop button at the front panel will immediately stop the engine and radiator fan (if equipped). Hydraulic pressure and flow will go to zero. This button must be in the out position to start the engine.

OPERATING DRIVEN

EQUIPMENT

The operator must know the hydraulic requirements and limitations of the driven equipment and the appropriate adjustments must be made on the controls. The introduction of other control devices may cause system heating or may render the system inoperative.

IMPORTANT: This power unit is equipped with a positive displacement gear pump. All tools must be equipped with a control valve that allows flow directly to return ports when not in use. Blocking oil flow or abruptly disconnecting the tool can send flow over relief and potentially overheat the system.

Instructions supplied with the driven equipment must be followed to ensure correct connection and operation of each individual piece of equipment. Equipment supplied by Diamond Products will be capable of being connected correctly and will be compatible with this power unit, providing neither has been modified from original factory configuration. With equipment of other manufacturers, it will be necessary to determine the following:  Correct direction of flow through the

equipment.

 Correct pressure and flow required by

the equipment.

 Compatibility of any valves or circuitry

and quick disconnects. Some handheld equipment uses a trigger control, which is operated frequently. These valves must be of the open center type for correct operation.

IMPORTANT must be clean when connecting hoses and devices. Dirty connections may result in contamination and premature failure of system or tool components.

: The quick disconnects

MAINTENANCE INSTRUCTIONS

 Oil Filter: change the filter when

indicated by the gage at the filter.

 Oil Change: establishing an oil analysis

program is the preferred method of determining oil condition and when to change it. If the oil is kept clean, dry, and operated at moderate temperatures, it can last for several years. With no analysis program an oil change every 200 hours is recommended. See the section Hydraulic Fluid for specifications. A ½” pipe thread oil drain port is at the bottom of the hydraulic tank.

 Gas Engine Oil: Change engine oil and

filter and perform other routine maintenance as recommended in the engine operation manual.

 Inspect hoses, couplings, and fittings

daily for leaks, tighten as required. Clean quick disconnects frequently. Replace any leaking or defective components immediately.

 Check hydraulic oil level daily. Fill tank

to upper end of sight tube with unit off.

 Grease the wheel bearings annually.

TROUBLESHOOTING

PROBLEM POSSIBLE SOLUTIONS

Gas engine will not start.

Low oil flow.

System builds high pressure with flow control valve set to zero.

Keep this manual and the engine manual readily available at all times for reference.

1) Pull out emergency stop button.

2) Open gas line valve below gas tank.

3) Dead battery?

4) Low engine oil? Check gas engine RPM at tachometer on front panel. Adjust governor to 3850 RPM if required. See engine manual. Contamination may have plugged an orifice in the CF port of the flow valve. Detach the valve from the front panel and remove the fitting from the CF port. A .015” orifice should be visible at the bottom of the port. Push a fine wire through the orifice and re-install.
