BEFORE STARTING THE ENGINE

1. Read the Operator Manual and Engine Manual. Be-

come familiar with the controls, how each functions, and what it operates.

OPERATION

5. After the engine starts and begins to warm, slowly pull the throttle lever rearwards until the throttle lever falls into the next detent. The unit is now in the maximum running position of the throttle and the choke is backed off. If not equipped with an “over travel” choke, back the choke off manually on the engine. See engine manual for details. The engine should run smoothly.

6. Set the desired engine speed with the throttle. The engine should run smoothly and with excessive vibration.

VACUUMING

2. Check the engine oil level and add if necessary. See engine manual for details.

3 Fill the fuel tank with good quality, clean, unleaded

regular gasoline (petrol). Use a funnel to avoid spill-

ing. See engine manual for details.

4. Check that the bag is securely attached to the discharge chute and handle posts and the bag is secured shut.

5. Check that the discharge chute is secured to the housing outlet.

STARTING THE ENGINE

1. Open the fuel valve (if equipped) and ensure the spark plug is connected.

2. For cold starts, move the throttle to the “CHOKE” position (forward most position) For engines without an

“over travel” choke, set the choke manually on the engine. See engine manual for details. (Choke may not be required to start a warm engine. Too much choke

use may ood the engine and cause hard starting.)

Before performing any type of maintenance on the machine, stop engine and wait for all parts to stop moving. Failure to follow this instruction could result in personal injury or property damage.

1. To adjust the nozzle to the selected height:

With one hand, lean the unit back slightly to take

some weight off the front wheels. Press inward on the height adjust handle and push forward to raise

the nozzle and backward to lower the nozzle. When you are satised with the height, allow the protruding

height adjust pin to fall into the nearest slot.

2. The debris bag is full when the unit begins to lean

backwards, or suction performance is insufcient.

Examples of items suitable to be vacuumed:

-leaves -dry mulch

-small twigs -litter

-acorns -thistles

-seed pods -small cans and bottles

-grass clippings -paper products

-straw -styrofoam products

-wood chips

3 For warm starts, move the throttle to midway between

the fast and slow positions.

4. Pull the recoil starter slowly until resistance is felt,

then pull rmly to start the engine.

Examples of items/areas to avoid.

-excessively wet surfaces and debris

-grocks or gravel surfaces
