PREPARATION FOR USE
ENGINE
NOTICE
Do not operate the TracHorse until you have read
the engine operating and maintenance instructions
manual furnished in addition to this manual.
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 oil as specified in the
engine operating and maintenance manual.
NOTICE
The engine oil sump must never be overfilled.
Overfilling can cause the engine to overheat and
cause crankshaft seal damage.
2. Engine Fuel Level
Check the fuel level. If low, fill with DF-1 or DF-2
diesel fuel (A.S.T.M. D975-66T No. 1 or no. 2 dark).
NOTICE
Shut the engine off before attempting to add fuel to
the fuel tank. Do not remove the fuel cap while the
engine is running. Do not add fuel to the tank while
the engine is hot. Do not fill the fuel tank to a point of
overflowing.
HYDRAULIC FLUID
Check the sight gauge in the hydraulic fluid reservoir for
the proper fluid level.
Use fluids meeting the following specifications.
VISCOSITY (FLUID THICKNESS)
U.S.METRIC
50 °F 450 SSU Maximum10 °C 95 Centistokes
100 °F 130–200 SSU38 °C 27–42 C.S.
140 °F 85 SSU Minimum60 °C 16.5 C.S. Minimum
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 fluids work well over a wide temperature
range at startup, allow moisture to settle out and resist
biological growth that may occur in cool operating hy-
draulic circuits. These fluids are recommended by Stan-
ley Hydraulic Tools. 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
BATTERY
The supplied battery is maintenance free.
NOTE:
Before starting the engine make sure the tool circuit
switch is in the OFF position.
DUAL CIRCUIT OPERATION
Facing the panel, the male quick disconnect fittings are
the PRESSURE FLUID OUT fitting. The female quick
disconnect fittings are the RETURN FLUID IN (RE-
TURN) fitting.
The "Dual Circuit" control panel contains connections for
two 5 GPM tool circuits. In addition, the two circuits may
be combined into one 10 GPM tool circuit.
