OPERATION
COUPLERS (HOSE CONNECTIONS)
Top Male Quick Disconnect
Couplers (Pressure Fluid Out)
Bottom Female Quick Disconnect Couplers (Return Fluid In)
Facing the control panel, the top (2) male couplers are the PRESSURE FLUID OUT fittings. The bottom (2) female quick disconnect couplers are the RETURN FLUID IN. Their are two independent circuits, one on the left and one on the right, each controlled by the adjacent lever.
CONTROLS (DUAL CIRCUIT)
Throttle Control Lever | Starter Switch |
Flow Control Lever(s) In Off Position
When the throttle control lever is in the far left position, it will produce 5 GPM to both circuits at the same time and with the lever in the far right position will produce 8 GPM to both circuits. This allows two tools that can run simultaneously at 5 or 8 GPM.
12 ► HP TWIN8 User Manual
The flow control levers when turned “ON” (up position) turns on flow to the tool or tools depending on if you are using one or both circuits.
STARTUP
1.Before starting the engine check the engine oil and hydraulic fluid level.
2.Check to make sure the flow Control levers are in the OFF position (Down), the power unit will not start if the levers are in the “UP” position (ON).
3.Connect hoses and the tool as described on page
9.
4.It is not necessary to choke the engine, it is equipped with a “Electronic Fuel Management System” that does not have a manual choke.
5.Set the throttle control lever to the left
6.Turn the Ignition Switch to the START position. After the engine starts, release the switch.
7.Allow the engine to warm up.
8.Turn on the flow to the tool by lifting the “Flow Control Levers” up into the on position, lift both levers if running two circuits (two Tools).
SHUTDOWN
1.Ensure the flow control levers are in the OFF position (Down).
2.Move the Ignition Switch to the OFF position.
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.
COLD WEATHER STARTUP
1.Use the procedures described under “STARTUP” and then follow the procedure below.
2.Hydraulic fluids are thicker in cold weather.
Therefore, it is recommended that the engine be run at low idle long enough to bring the fluid temperature up to a minimum of 50 °F/10 °C.
3.If the tools and tool hoses are cold, it is recommended to allow hydraulic fluid to circulate through the tool hoses until warm before using the tool.
