COLD WEATHER STARTUP
1. Use the procedures described under "STARTUP" and
then follow the procedure below.
2. Hydraulic fl uids are thicker in cold weather. Therefore,
it is recommended that the engine be run at low idle long
enough to bring the fl uid 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 fl uid to circulate through the tool hoses
until warm before using the tool.
SHUTDOWN
1. Ensure the fl ow selector switch in the OFF position
(center position).
2. Unless already at idle the power unit should return to
idle. This may take a few seconds for the unit to react due
to a built-in program delay.
3. Allow the engine to idle for approximately one minute
and move the Ignition Switch to the OFF position.
OPERATION
it is good practice to start the power unit with the AC Con-
trol Switch in the OFF position. The unit will however start
with this switch in either the ON or OFF position.
Note:
If the power unit is started in the ON position, the 110
volt AC outlet will not funtion unless the switch is
turned off and back on again.
Turn the Ignition Switch to the START position. After the
engine starts, release the switch.
Gradually push in the choke knob as the engine begins to
idle smoothly.
Allow the engine to warm up.
Connect hoses and the tool as desrcribed on pages 9 and
10.
FOR 5 GPM OPERATION
For 5 gpm operation, select mode of operation with the
Throttle Control switch, either auto-idle-on or the auto-idle-
off position. Move the fl ow selector switch to the 5 gpm
position.
When fi nished operating the tool, move the fl ow selector
switch to the OFF position.
FOR 8 GPM OPERATION
For 8 gpm operation, select mode of operation with the
Throttle Control Switch, either auto-idle-on or the auto-idle-
