Pre-Start
1.
Check engine oil level. Refer to engine Operating
and Maintenance Instructions for correct oil type and
checking instructions.
2.
Check fuel level. Refer to engine Operating and
Maintenance instructions for fuel recommendations.
3.
Check hydraulic reservoir oil level. Fill to FULL mark
on dipstick. See Maintenance. See Recommended
Hydraulic Fluids for correct hydraulic fluid.
4.
Verify that all current maintenance has been
performed on the power unit. See Maintenance.
5.
Connect the tool hoses and tool to the power unit.
See Hose Connections.
Starting the Power Unit (See Figure 4)
1.
Move the two flow levers (1) to the NEUTRAL
position.
2.
Pull out the choke knob (2).
Note: A warm engine requires less choking than a cold
engine.
3.
Move throttle lever (3) out to the fully open position.
4.
Move the key switch (4) to the ON position.
5.
Turn key to start position to start engine.
Note: The best starter life is provided by using short
starting cycles of several seconds. Prolonged
cranking, more than 15 seconds per minute, can
damage the starter motor.
6.
After the engine has started, reduce the rpm.
Slowly open choke.
7.
Position the two flow levers (1) to the desired
setting—5 or 10 gpm.
Note: Both levers must be set at 10 gpm position for
operation with 10 gpm output.
8.
It is recommended that the power unit be allowed to
run (idle) for a few minutes to warm the hydraulic
reservoir fluid. Actuating the tool intermittently will
reduce the time required to warm the fluid to an
efficient operating temperature.
9.
Using the engine throttle lever (3), adjust the engine
rpm to obtain the rated hydraulic oil flow. DO NOT
EXCEED THE MAXIMUM ALLOWABLE FLOW
RATE FOR THE TOOL BEING USED WITH THE
POWER UNIT. See your tool operator’s manual for
proper flow rate.
