3.7 RUN IN – 52" UNITS ONLY
3.7.1 Follow the operation instructions in Section 5 to run the unit. Run the unit with the
blades and blower engaged for 2 minutes. Disengage the blades, stop engine and
wait for all moving parts to stop. Remove key.
3.7.2 Remove the belt cover and check to make sure that the belt is riding near the
center of the flat idler on the idler arm. If the belt is not riding near the center of the
idler, remove the blower, and bend the idler arm slightly. Reinstall the blower and
belt cover and perform steps 1 and 2 again to verify belt position.

4. OPERATION:

4.1 PRE-START

4.1.1 Read the operator's manual for your mower and familiarize yourself with all
controls before operating the machine. Make sure that you understand the
controls, their locations, their functions, and their safety requirements.
4.1.2 Ensure the blower, belt cover, bags, tube and hood are in good condition,
properly attached, and latched.
Note: When mowing in areas with sandy soil, use low lift blades on the cutting
deck and higher cutting heights to minimize wear on the blower components.

4.2 MOWING

4.2.1 The Ultra Vac blower operates when deck drive is engaged. Be sure that all
persons are clear of the mower deck and blower before engaging the cutting
blades. Set the throttle to "midway" position. Pull outward on the PTO switch to
the "ROTATE" position. Accelerate to full throttle to begin mowing.
