HYDRAULIC HOSE REQUIREMENTS

HOSE TYPES

The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the
hydraulic system.There are three types of hydraulic hose that meet this requirement and are authorized for use
with Stanley Hydraulic Tools. They are:

Certifi ed non-conductive - constructed of thermoplastic or synthetic rubber inner tube, synthetic fi ber
braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certifi ed non-

conductive is the only hose authorized for use near electrical conductors.

Wire-braided (conductive) - constructed of synthetic rubber inner tube, single or double wire braid rein­forcement, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near

electrical conductors.

Fabric-braided (not certifi ed or labeled non-conductive) - constucted of thermoplastic or synthetic rubber
inner tube, synthetic fi ber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This

hose is not certifi ed non-conductive and must never be used near electrical conductors.

HOSE SAFETY TAGS

To help ensure your safety, the following DANGER tags are attached to all hose purchased from Stanley Hydrau­lic Tools. DO NOT REMOVE THESE TAGS.

Automatic throttle Control

In this mode, engine speed varies with hydraulic circuit
pressure during tool use to maintain a constant 7 gpm/26
lpm. When a tool is not being used the engine will return to
idle automatically.

Automatic Throttle Control is set by positioning the adjust­ment knob (shown in fi gure 4) to the far right and tightening
it to maintain its position.

Manual Throttle Control

In this mode, engine speed is manually held at full throttle
to maintain 7 gpm/26 lpm. When a tool is not being used
the engine will not return to idle until the manual setting is
removed.

OPERATION

• When operating drills or grinders or pumps, tool rpm
must be maintained even when load requirements are
light.

START-UP

Manual Throttle Control is set by positioning the knob
(shown in fi gure 4.) to the far left and tightening it to main-
tain its position.

Shown above in Figure 5 are the primary engine compo­nents referred to in this section. Become familiar with these
components and read and understand the engine operation
and maintenance manual before starting the engine and
operating the power unit for the fi rst time.

Before starting the engine, make sure the throttle
control knob is set for "Auotmatic Throttle Con­trol".

START-UP

1. Check the engine oil level.

2. Check the hydraulic oil level.

trol lever to the OFF positon.

COLD WEATHER STARTUP

1. Use the procedures described under "STARTUP" and
then follow the procedure below.

2. Hydraulic fl uids are thicker in cold weather. Therefore,
it is recommended that the engine be run at low idle long
enough to bring the fl uid temperature up to a minimum of
50°F/10°C.

3. If the tools and tool hoses are cold, it is recommended
to allow hydraulic fl uid to circulate through the tool hoses
until warm before using the tool.

Figure 7. Fuel Lever

7. Position the engine ON-OFF switch to the ON position
as shown in fi gure 8.

resistance. Then pull fi rmly upward. Do not allow the starter
grip to snap back against the engine. Return it gently.

SHUTDOWN

1. Ensure the tool circuit control lever is in the OFF posi­tion.

2. Unless already at idle the power unit should return to
idle if operating in the "automatic" mode. If operating in
the manual mode, move the knob to the far right position
and tighten it to maintain its position.

3. Allow the engine to idle for approximately one minute
and move the engine switch to the OFF position.

9. After the engine starts, allow it to warm up. Gradually
adjust the choke until it is in the open position.

10. Connect hoses and the tool as desrcribed on pages 9

ROUTINE MAINTENANCE

ENGINE MAINTENANCE

Follow the maintenance schedule and general maintenance
instructions in the engine maintenance and operation
manual furnished with the power unit.

HYDRAULIC SYSTEM MAINTENANCE

• Check hydraulic fl uid level daily. Add fl uid per specifi ca-
tions in this manual. (See "HYDRAULIC FLUID" under the
section titled "OPERATING INSTRUCTIONS".

• Remove condensed moisture from the hydraulic
fl uid by pumping the hydraulic fl uid into a 5 gal/20 l con-
tainer through the pressure hose. Make sure the engine is
at idle when performing this procedure. When the hydraulic
reservoir is empty turn the engine off immediately.

• Allow the fl uid to sit long enough for the water to settle to
the bottom of the container. Slowly pour the fl uid back into
the hydraulic tank, avoiding the water at the bottom of the
container.

• Each day, check hydraulic lines and fi ttings for leaks,
kinks, etc. Do not use your hand to perform this check.

STORAGE

• Clean the unit thoroughly before storage. Do not use
water pressure.

• Always store the unit in a clean and dry facility.

• If the unit will be stored for a prolonged period (over 30
days), add a fuel additive to the fuel tank to prevent the fuel
from gumming. Run engine for a short period to circulate
the additive.

• Replace crankcase oil with new oil.

• Remove the spark plug and pour approximately 1 ounce
(30 ml) of engine oil into the cylinder. Replace the spark
plug and crank the engine slowly to distribute the oil.

• Check hydraulic reservoir for water. If water is found,
change the oil and circulate it through the tool hose and
tool. (See "HYDRAULIC SYSTEM MAINTENANCE" earlier
in this section).

• Change the hydraulic fi lter element every 200 hours of
operation. Change more often if cold, moist or dusty condi­tions exist.

• Check oil cooler for debris. Remove debris with air pres­sure.

14

TESTING & TROUBLESHOOTING

GENERAL

4. Start the engine and allow it to run until warm.

Tests and adjustments should be performed periodically to
ensure the power unit is operating at maximum effi ciency.
Stanley Circuit Tester (part number 04182) is recommend­ed. This tester can be used to isolate problems in both the
engine and hydraulic system prior to any power unit disas­sembly.

TESTING THE HYDRAULIC CIRCUIT

The following tests can be performed to ensure that the
hydraulic pump is supplying the correct fl ow and pressure
and that the system relief valve is operating properly.

During these tests, make sure the engine is warm and op­erating smoothly. If test results are not as specifi ed, refer to
the troubleshooting table in this section for possible causes.

TESTING THE 7 GPM HTMA TYPE 1 CIRCUIT

To test the circuit, proceed as follows:

1. Set the throttle control knob to the automatic position.

2. Connect the Stanley Circuit Tester across the hose ends
(where the tool would normally be connected).

3. Fully open the tester restrictor valve (counterclockwise).

5. With the engine at full operating speed, the test fl ow
gauge should read 7 gpm/26 lpm.

6. Slowly turn the restrictor valve clockwise while watching
the pressure gauge. The fl ow rate should stay at 7 gpm/26
lpm as the pressure gauge reaches 2100-2200 psi/148-155
bar.

7. At 2100-2200 psi/148-155 bar, the relief valve should
begin to open. The pressure at which the relief valve just
begins to open is commonly referred to as the "cracking
pressure". At the "cracking pressure," the fl ow rate should
start to drop because the relief valve is allowing fl uid to by-
pass to the hydraulic reservoir. The "cracking pressure" is
preset at the factory and if it is not within the above range,
the relief valve must be re-set as follows:

a. The relief valve is located behind the dash panel in the
manifold assembly. Use an open end or box end wrench to
loosen the nut on the relief valve.

b. Use an Allen wrench to adjust the relief valve. Turn
clockwise to raise the pressure and counterclockwise to
reduce the pressure.

c. Tighten the nut and retest.
