Operation; Preparation For Use; Hydraulic Connections - Stanley HP1 Safety, Operation And Maintenance 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
IMPORTANT
Do not start the Engine with the
trottle control set at 5 or 8 gpm/
19 or 30 lpm.
Always check the oil level before starting tne
engine. Make sure the oil level is at the FULL
MARK on the dipstick. Do not overfill. Use deter-
gent oil classified "For Service SE, SF, SG" as
specified in the engine operating and maintenance
manual.
2. ENGINE FUEL LEVEL
Check the fuel level. If low, fill with un-leaded
gasoline with a minimum of 85 octane.
3. HYDRAULIC FLUID
Check the sight pipe in the hydraulic fluid reservoir
for the proper fiuid level. Proper fluid level is
indicated when the center section of the sight pipe
is dark. If the center section of the sight pipe is not
dark, add hydraulic fluid. Use fluids meeting the
following specifications.
Viscosity (Fluid Thickness)
U.S.
50°F 450 SSU Maximum
100°F 130-200 SSU
140°F 85 SSU Minimum
PourPoint -10°F/-23°C Minimum (for cold startup)
Viscosity Index (ASTM D-2220) 140 Minimum
Demulsibility (ASTM D-1401) 30 Minutes Maximum
OPERATING INSTRUCTIONS
METRIC
10°C 95 Centistokes
38°C 27-42 C.S.
60°C 16.5 C.S. Minimum
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 fluids work well over a wide tempera-
ture 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

4. HYDRAULIC CONNECTIONS

Facing the panel control valve, the far right-hand
male quick disconnect fitting is the pressure
(FLUID OUT) fitting. The left-hand female quick
disconnect fitting is the return (FLUID IN) fitting.
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. (HYDRAU-
LIC TOOL MANUFACTURERS ASSOCIATION)
5. BATTERY
The supplied 12 Volt DC battery has been partially
dry charged. Before using, it must first be filled
with battery electrolyte at a specific 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 fill as required.
Also, make sure the battery cables are tight and
charging circuit functions are operating properly.
