OPERATION
3. Ensure the tool circuit switches are in the OFF posi-
tion.
4. Pull the choke out until it stops.
5. Turn the ignition switch clockwise to begin cranking
the engine. Use short starting cycles (15 seconds
per minute) to prolong starter life. Extended crank-
ing can damage the starter motor.
6. After the engine starts, allow it to warm-up for a few
seconds before moving the choke. Move the choke
inward in small steps to allow the engine to accept
small changes in speed and load. Continue moving
the choke in until it is fully off and the engine is run-
ning smoothly.
7. Place the throttle at the maximum setting.
8. Position each tool circuit switch to 5 GPM. The tools
can now be used.
9. Reverse the above procedure to stop using the
tools.
DUAL CIRCUIT COMBINED FOR 10 GPM
1. To combine the two 5 GPM tool circuits into one 10
GPM tool circuit, connect the PRESSURE FLUID
OUT hose to either one of the two male couplers.
Connect the RETURN FLUID IN (RETURN) hose
to either one of the two male couplers. Connect the
other ends of the hoses to the tool.
2. Ensure the throttle control is pulled fully back to the
idle position.
3. Ensure the tool circuit switches are in the OFF posi-
tion.
4. Pull the choke out until it stops.
5. Turn the ignition switch clockwise to begin cranking
the engine. Use short starting cycles (15 seconds
per minute) to prolong starter life. Extended crank-
ing can damage the starter motor.

ning smoothly.

can now be used.
9. Reverse the above procedure to stop using the tool.
COLD WEATHER STARTUP
1. Use the procedures below for starting the engine
and using the tool circuits or driving the TracHorse
in cold weather.
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 hydraulic uid tem-
perature up to a minimum of 50 °F/10 °C.
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.
SHUTDOWN
1. Ensure each ow selector switch is in the OFF posi-
tion.
2. Move the throttle control to idle.
3. Allow the engine to idle for approximately one min-
ute and move the Ignition Switch to the OFF posi-
tion.
NOTICE
If the engine runs out of gas or dies during operation
and the ignition switch is left in the ON or RUN
position, this could drain the battery. Make sure the
ignition switch is returned to the OFF position.
