NOTICE
If the engine runs out of fuel or dies during operation
or if the stop knob is pulled and the ignition switch
is left in the ON position, the battery may become
discharged. Make sure the start switch is returned to
the OFF position.
COLD WEATHER STARTUP
1. Use the procedures described under “Starting The
Engine” and then follow the procedures below.
2. Hydraulic uids are thicker in cold weather, there-
fore, 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.
3. If the tools and tool hoses are cold, it is recommend-
ed to allow hydraulic uid to circulate through the
tool hoses until warm before using the tools.
ENGINE SHUTDOWN
Place both control levers in the OFF position. Push the
throttle control completely in. Allow the engine to idle for
approximately one minute, turn the switch to OFF, and
then pull the stop knob to shutdown the unit. Make sure
the start switch is in the off position.
HYDRAULIC TOOL CIRCUIT CONTROLS
The MHP3 TracHorse provides two circuits, each with
an oil ow of 5 gpm/19 lpm up to 2000 psi/140 bar. Or
the two circuits may be combined into one circuit provid-
3. Ensure the tool circuit levers are in the OFF position.
4. If starting the engine in cold weather conditions turn
the start switch until the battery charge light comes
on. Then press and hold the glow plug button for 10-
15 seconds. Release the glow plug button and turn
the start switch to the third start position to crank the
engine.
5. Turn the start switch clockwise to begin cranking the
engine. Use short starting cycles (15 seconds per
minute) to prolong starter life. Extended cranking
can damage the starter motor.
6. After the engine starts, allow it to warm-up.
NOTE:
Hydraulic uids are thicker in cold weather. It is rec-
ommended that the engine be operated at low idle
long enough to allow the uid temperature to warm
to a minimum of 50 °F.
7. When the engine is warmed up the throttle may be
advanced and the hydraulic tool circuits may be
used.
