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:
Certied non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certied 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 certied or labeled non-conductive) — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This
hose is not certied non-conductive and must never be used near electrical conductors.

ENGINE MAINTENANCE
Follow the maintenance schedule and general maintenance instructions in the engine maintenance and operation manual furnished with the power unit. Also see
maintenance schedule on pages 15 & 16.
HYDRAULIC SYSTEM
MAINTENANCE
• Check hydraulic uid level daily. Add uid per specications in this manual. (See HYDRAULIC FLUID
under the section titled OPERATION.
• Remove condensed moisture from the hydraulic
uid by pumping the hydraulic uid into a 5 gal/20
l container through the pressure hose. Make sure
the engine is at idle when performing this procedure.
When the hydraulic reservoir is empty turn the en-
gine off immediately.
• Allow the uid to sit long enough for the water to
settle to the bottom of the container. Slowly pour the
uid back into the hydraulic tank, avoiding the water
at the bottom of the container.
• Each day, check hydraulic lines and ttings for
leaks, kinks, etc. Do not use your hand to perform
this check.
• Change the hydraulic lter element every 100 hours
of operation or 6 months which ever comes rst.
Change more often if cold, moist or dusty conditions
exist.
• Check oil cooler for debris. Remove debris with air
pressure.
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 distrib-
ute 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).
• Disconnect tool hoses.

TESTING & TROUBLESHOOTING
GENERAL
Tests and adjustments should be performed periodically
to ensure the power unit is operating at maximum efciency. 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 ow and pres-
sure 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 specied,
refer to the troubleshooting table in this section for possible causes.
TESTING THE 5 GPM HTMA TYPE 1 OR 8
GPM HTMA TYPE II CIRCUIT
To test the circuit, proceed as follows:
1. Set the throttle control lever to the far left or full throttle 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).
4. Start the engine and allow it to run until warm.
5. With the engine at full operating speed, the test
ow gauge should read 4–6 gpm/15–23 lpm on
GPV135H02 or 7-9 gpm/26-34 lpm on GPV138B02.
6. Slowly turn the restrictor valve clockwise while watching the pressure gauge. The ow rate should stay at
4–6 gpm/15–23 lpm as the pressure gauge reaches
1900–2000 psi/131–138 bar on GPV135H02 or 7–9
gpm/26–34 lpm as the pressure gauge reaches
1900–2000 psi/131–138 bar on GPV138B02.
7. At 1900–2000 psi/131–138 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 ow rate should start to drop because the
relief valve is allowing uid to bypass 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 pan-
el in the valve 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.
