Pre-Operation - Stanley HP Twin 8 User Manual

PREPARATION FOR USE
Do not operate the power unit until you have read the engine
operating and maintenance instructions manual furnished
with the unit.
1. ENGINE CRANKCASE OIL LEVEL
Always check the oil level before starting the engine. Make
sure the oil level is at the FULL MARK on the dipstick. Do not
overfill. Use detergent oil classified "For Service SF, SG, SH,
SJ or higher" as specified in the engine operators manual.
Do not use special additives. Outdoor temperatures deter-
mine the proper oil viscosity for the engine. Use the chart to
select the best viscosity for the outdoor temperature range
expected.

* Below 40°F (4°C) the use of SAE 30 will result in hard
starting.
** Above 80°F (27°C) the use of 10W-30 may cause
increased oil consumption. Check oil level more
frequently.
2. ENGINE FUEL LEVEL
Check the fuel level. If low, fill with clean, fresh unleaded
gasoline with a minimum of 87 octane. Gasoline with up to
10% ethanol (gasohol) is acceptable.
3. HYDRAULIC FLUID
Check the sight gauge on the side of the hydraulic fluid reser-
voir for the proper fluid level. Use fluids meeting the following
specifications.
VISCOSITY (FLUID THICKNESS)
The following fluids work well over a wide temperature
range, allow moisture to settle out and resist biological
growth that may occur in cool operating hydraulic
circuits. These fluids are recommended by Stanley.
Other fluids that meet or exceed the specifications of
these fluids may also be used.
• Chevron AW-MV-32
• Exxon "Univis" J-26
• Mobil D.T.E. 13
• Gulf "Harmony" AW-HVI-150-32
• Shell "Tellus" T-32
• Texaco "Rando" HD-AZ
• Union "Unax" AW-WR-32
• Terresolve EnviroLogic 132
4. HYDRAULIC CONNECTIONS
The recommended hose length is 25 ft/8 m with a
1/2 inch/12.7 mm inside diameter. The hoses must
have a working pressure rating of at least 2500
psi/175 bar. Each hose end must have male thread
°C ends compatible with HTMA (HYDRAULIC TOOL
MANUFACTURERS ASSOCIATION) quick disconnect
40
fittings (NPT type threads). (See pages 8 and 9).

QUICK DISCONNECT COUPLERS
20
HTMA-approved quick disconnect couplings are
10
installed to hydraulic hoses so that the direction of
oil flow is always from the male to the female quick

disconnect as shown on page 9. Quick disconnect
couplings and hose fittings are selected so that
-10
additional fittings such as reducer or adapter fittings are
-20
not required.
-30 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.
5. BATTERY
The supplied 12-Volt DC battery is a sealed non-
spillable, maintenance-free battery and is fully charged.
Make sure the battery cables are tight and charging
circuit functions are operating properly.
A fully charged battery should read 12.8V -13.0V.
Caution, overcharging can harm your battery beyond
recovery. When using an automatic charger, refer to
the charger manufacturer's instructions.
