Stanley Black & Decker MHP3 Cold Weather Startup, Shutdown, DUAL CIRCUIT COMBINED FOR 10 GPM

OPERATION

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.

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 fluids are thicker in cold weather. There- fore, it is recommended that the engine be run at low idle long enough to bring the hydraulic fluid 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 fluid to circulate through the tool hoses until warm before using the tools.

SHUTDOWN

1.Ensure each flow 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.
