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 overfi ll. Use detergent oil classifi ed "For Service SE, SF,
SG" as specifi ed in the engine operating and maintenance
manual. See engine manual for oil viscosity grade.
2. SPARK PLUG
On power units equipped with Briggs & Stratton Engines,
ONLY Champion RC12YC or equivalent can be used.
For power units equipped with Honda Engines, ONLY
Denso J16CR-U or equivalent can be used.
Incorrect type spark plugs can produce radio frequency
interference that will corrupt and damage the controller.
Failure to use the correct spark plug could result in a war-
ranty that will not be considered.
3. ENGINE FUEL LEVEL
Check the fuel level. If low, fi ll with un-leaded gasoline with
a minimum of 85 octane.
4. HYDRAULIC FLUID
Check the dip stick in the hydraulic fl uid reservoir for the
proper fi uid level. Use fl uids meeting the following specifi -
cations.
Viscosity (Fluid Thickness)
U.S. METRIC
50°F 450 SSU Maximum 10°C 95 C.S.
100°F 130-200 SSU 38°C 27-42 C.S.
140°F 85 SSU Minimum 60°C 16.5 C.S. Min
Pour Point -10°F/-23°C Minimum (for cold startup)
Viscosity Index (ASTM D-2220) 140 Minimum
Demulsibility (ASTM D-1401) 30 Minutes Maximum
Flash Point (ASTM D-92) 340°F/171°C Minimum
Rust Inhibition (ASTM D-665 A & B) Pass
Oxidation (ASTM D-943) 1000 Hours Minimum
Pump Wear Test (ASTM D-2882) 60 mg Maximum
The following fl uids 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 fl uids are recommended by Stanley. Other fl uids
that meet or exceed the specifi cations of these fl uids 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
5. 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 ends compatible with
H.T.M.A. (HYDRAULIC TOOL MANUFACTURERS AS-
SOCIATION) quick disconnect fi ttings (NPT type threads).
(See Figure 2.)
Figure 1. Panel Control Valve
Facing the panel control valve, the bottom male quick
disconnect fi tting is the PRESSURE FLUID OUT fi tting. The
top female quick disconnect fi tting is the RETURN FLUID
IN fi tting.
QUICK DISCONNECT COUPLERS
H.T.M.A. approved quick disconnect couplings are installed
to hydraulic hoses so that the direction of oil fl ow is always
from the male to the female quick disconnect as shown in
fi gure 2. Quick disconnect couplings and hose fi ttings are
