Chapter 3: Operating the DR PRO MAX450
™ LEAF AND LAWN VACUUM
It may be helpful to better familiarize yourself with the features of your DR PRO MAX450
™ LEAF and
LAWN VACUUM by
reviewing
Figure 1
in Chapter 2 before beginning the steps outlined in this chapter.
Before Starting the Engine
1.
Connect the DR PRO MAX450
™ LEAF and LAWN VACUUM
to your Lawn
Tractor (see previous chapter), remove the Safety Hitch Pin from the Jack (if
equipped), raise the Jack up and out of the way and replace the Safety Hitch
Pin.
2.
Check the Engine oil level every time you use the machine (refer to your
Engine Operator
’s
Manual).
3.
Check the Fuel level and make sure the Fuel Shut-Off Valve is in the OPEN
position (refer to your Engine Operator
’s
Manual).
Starting and Stopping the Engine
1.
When starting a cold Engine; push the Choke Control lever to the left (CHOKE) position and the Throttle Control lever to the
far left (rabbit) position (
Figure 63
). If re-starting a warm Engine, leave the Choke in the (RUN) position.
2.
Turn the Engine Switch to the "ON" position.
3.
Manual Start - Grasp the Recoil Starter Handle and slowly pull until you feel resistance, then pull the cord with a smooth
accelerating motion to start the engine. One or two pulls usually starts the DR LEAF and LAWN VACUUM.
Electric Start - Turn the Key to START until the Engine starts and then release. The Key will snap back when released and the
Engine will continue to run.
4.
After the Engine starts when the Choke is on, the Engine will soon begin to run rough. Adjust the Choke Lever until the engine
runs smoother. Continue this process until the engine runs well with the Choke fully in the run position. When vacuuming you
must operate the Engine with the Throttle in the Fast (Rabbit) position.
5.
To stop the Engine
, move the Throttle to the Slow (Turtle) position allowing the Engine to idle, shut off the gas, and then turn
the Engine Switch to
“OFF”
position.

potentially hazardous obstacles such as stones, metal, or glass. Also,
make sure there won't be people or animals in the area around the DR
