Remove all debris and coarse dust from the collector prior to starting the engine. The
previous photo shows the location of the dust collector. Review the service and
maintenance section of the engine manual for further instructions.
Check the oil condition and level in the oil bath air cleaner. If the oil needs
replacement, then follow the instructions for cleaning and replacement in the engine
manual. The cleaner is detailed in the previous photo.
Hydraulic System Inspection
The following steps review the hydraulic system to ensure it is ready for operation.
Check the fluid level of the hydraulic tank. For operation, the fluid level should be
seen in the level gauge as detailed in the following photo. If the level is low, then add
hydraulic fluid through the filler/breather until the level reaches the top of the level
gauge. When the filler/breather cap is removed, take care to avoid the passage of
contaminants into the hydraulic reservoir. A premium hydraulic fluid is
recommended for use such as Shell Tellus® 32 for average ambient operating
temperatures below 45°F (7°C), Shell Tellus® 46 for 45° to 85°F (7° to 30°C)
operation and Shell Tellus® 68 for operation above 85°F (30°C).
The level gauge has a built in thermometer that displays the temperature of the oil in
the reservoir. The power unit should not be operated when the oil temperature is
above 160°F (71°C).
Open the louvers on the heat exchanger prior to operation. They are closed for
transport to protect the heat exchanger core.

Ensure the suction line ball valve is in the open position. Starting the unit with the
ball valve closed will cause serious damage to the hydraulic pump. The ball valve is
mounted on the suction port of the tank.
