a The table gives the values under the standard condition (Atmospheric temperature: 25 Β°C, Atmospheric
pressure: 99.9 kPa {750 mmHg}).
a Since the dynamometer loads, output, and torque in the table are measured with the fan removed, they
are different from the specification values.
a The values in the table are the standard values for machines with the muffler and air cleaner installed, al-
ternator under no load, and air compressor open (if installed).
a The dynamometer load in this table shows the value when the dynamometer arm is 716 mm long.
a For fuel, use ASTM D975 No. 1 or No. 2.
a For lubricant, use SAE15W-40 or SAE30 oil.

<How to use check sheet>
Carry out the above troubleshooting and take a record of the contents of the attached βCheck sheet for no-
pressure feedβ.
Note 1: Check the low-pressure circuit parts for the following items.
1) Fuel level
2) Clogging of fuel tank breather
3) Sticking and wear of feed pump and clogging of filter
4) Leakage through and clogging of low-pressure fuel piping
5) Clogging of fuel filter
6) Replace the fuel filters when trouble doesnβt cancel it even if clogging is checked.
