HOSE TYPES

The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hy-

draulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with

Stanley Hydraulic Tools. They are:

Certied non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid

reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certi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 reinforce-

ment, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near

electrical conductors.

Fabric-braided (not certied or labeled non-conductive) — constructed of thermoplastic or synthetic rubber in-

ner tube, synthetic ber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This

hose is not certi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.

QUICK DISCONNECT COUPLERS

H.T.M.A. approved quick disconnect couplings are installed

to hydraulic hoses so that the direction of oil ow is always

from the male to the female quick disconnect as shown in

gure 2. Quick disconnect couplings and hose ttings are

selected so that additional ttings such as reducer or adapt-

er ttings are not required.

If adapter ttings are used, they must be approved steel

hydraulic ttings meeting a minimum operating pressure

rating of 2500 psi/172 bar. Do not use galvanized pipe t-

tings or black pipe ttings.

Use thread tape or pipe joint compound when installing

quick disconnect couplings to hose or tool ttings. Follow

the instructions furnished with the selected thread sealant.

DO NOT OVERTIGHTEN THE FITTINGS.

5. BATTERY

The supplied 12 Volt DC battery has been partially dry

charged. Before using, it must rst be lled with battery

electrolyte at a specic density of 1.240 to 1.260. Fill each

cell to its upper level indicator and then charge at a 2 Amp

rate for at least 12 to 15 hours. After charging, check the

electrolyte level and ll as required.

Also, make sure the battery cables are rmly xed and

charging circuit functions are operated properly.

NOTICE

Do not charge the battery with a standard automotive

battery charger. This type of charger produces a

charging amperage higher than 2 amps. Charging

the battery at higher than 2 amps will damage the

battery.

NOTICE

If the engine runs out of gas or dies during operation

and the ignition switch is left in the ON or RUN

position, this could drain the battery. Make sure the

ignition switch is returned to the OFF position.

OPERATION

CONTROLS

The GPV18 maximum pressure is 175 bar/2500 psi with a

ow adjustment from 20 Lpm/5 gpm to 30 Lpm/8 gpm by

rotating the ow control switch.

Figure 3. Control Panel

One hydraulic tool can be connected to the tool circuit. The

circuit is activated by rst selecting 5 or 8 gpm with the ow

control switch, then rotating the output control switch to the

“ON” position.

STARTUP

Assure the output control switch is in the “OFF” position

before startup. Pull out on the “Choke” control lever and

turn the start switch to the “Start” position, after the engine

starts let go of the key and the start switch will remain in the

“Run” position, allow the engine to warm up for 3-5 minutes

until it runs smoothly with the choke pushed back in. Then

connect the hose, turn the ow control switch into 20 Lpm/5

gpm or 30 Lpm/8 gpm (depending on your tool),and turn

the output control switch into “NO’ position and the tool can

be operated.

SHUTDOWN

Place the output control switch in the “OFF” position and

turn the ow control switch to “Idle” position. Then turn the

startup switch to “Stop” or shutdown position.

COLD WEATHER STARTUP

Hydraulic uids are thicker in cold weather, therefore, it

is recommended that the engine be run at low idle long

enough to bring the uid temperature up to a minimum of

50°F/10°C or until the top of the hydraulic lter feels warm.

If the tools and tool hoses are cold, it is recommended to

allow hydraulic uid to circulate through the tool hoses until

warm before using the tool.

ROUTINE MAINTENANCE

ENGINE MAINTENANCE

Follow the maintenance schedule and general mainte-

nance instructions in the engine maintenance and opera-

tion manual furnished with the power unit.

•Service foam air pre-cleaner every 25 hours of operation.

•Service air paper cartridge every 100 hours of operation.

•Replace in-line fuel lter every 100-300 hours or sooner if

required.

•Replace spark plugs every 100 hours of operation.

•Change engine oil after rst 5 hours of operation, then

after every 50 hours of operation. If engine has been op-

erating under heavy load or in high ambient temperature,

change the oil every 25 hours of operation.

•Change oil lter when engine oil is changed.

•Check oil level daily.

•Remove dirt and debris from engine with a cloth or brush

daily. Do not use water spray.

•Clean air cooling system every 100 hours of operation.

HYDRAULIC SYSTEM MAINTENANCE

• Check hydraulic uid level daily. Add uid per specica-

tions in this manual. (See "HYDRAULIC FLUID" under

the section titled "OPERATING INSTRUCTIONS". KEEP

HYDRAULIC FLUID CLEAN.

• Remove condensed moisture from the hydraulic

uid by pumping the hydraulic 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 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 per :Engine Mainte-

nance on this page. Change more often if cold, moist or

dusty conditions exist.

• Check oil cooler for debris. Remove debris with air pres-

sure.

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 spark plugs and pour approximately 1 ounce (30

ml) of engine oil into each cylinder. Replace spark plugs

and crank the engine slowly to distribute the oil. Check hy-

draulic reservoir for water. If water is found, change the oil

and circulate it through the tool hose and tool. (see hydrau-

lic system maintenance section ).Disconnect tool hoses.

Install new hydraulic uid lter if dirty.
