). Do not change engine governor settings.

6. Do not put hands near rotating parts for any
reason.

7. If the power vacuum should start to vibrate

abnormally, stop the engine and check immedi
ately for the cause. Vibration is generally a
warning of trouble.

10. Check all bolts for tightness at frequent periods.

11. Never store this power vacuum with fuel in the

Also keep throttle control lever in the stop

position.

9.

If the power vacuum should become blocked with

debris at any point, shut engine off and wait
until the impeller comes to a complete stop
before attempting to remove the obstruction.
Disconnect spark plug wire to prevent accidental

starting.

17. Check the vacuum bag frequently for wear and
replace when necessary.

HANDS AWAY FROM ALL

OPENINGS

TO START ENGINE

After the engine has been properly fueled and oiled
(refer to engine operating and maintenance instruc
tions), start engine following the instructions below.

1. Move throttle control lever on engine to START

position.

2. Crank engine. Pull recoil with quick firm pull.
Do not pull out so far the rope stops with-a jerk

as this will cause rope failure. Do not allow rope
and handle to snap back into place.

3. After two or three full firm pulls on recoil (or as

soon as engine fires), move speed control to

RUN position.

4. Self Propelled Models Only - To engage the drive

mechanism, squeeze the clutch grip against the
upper handle. Release the clutch grip to stop the
forward motion.

ADJUSTMENTS

CAUTION

A

Do not at any time make any adjust

ment to the unit without first stopping
engine and disconnecting spark plug
wire.

HEIGHT ADJUSTMENT

To adjust the height of the nozzle, stand on the right
hand side of vacuum and move the index handle
towards the engine. Move handle towards rear of unit

to lower height. Move the handle forward to raise the

height. See figure 17.

TO STOP ENGINE

1. To stop engine, move throttle control lever to

STOP position.

2. Disconnect spark plug wire and ground to prevent

accidental starting while equipment is unattended.

Operate a new engine at intermediate speeds and light
load for the first few hours as you would a new
automotive engine.

IMPORTANT

The vacuum bag may have an air escape

located on the upper right hand side.
See figure 16. The air escape can be
opened if the vacuum is operated in
wet, sandy or muddy conditions.

FIGURE 17

CARBURETOR ADJUSTMENT

A

If any adjustments are made to the

engine while the engine is running
(e.g. carburetor), disengage all clutches.

Keep clear of all moving parts. Be

careful of heated surfaces and muffler.

If carburetor needs adjustment to start or for oper

ation, see "Carburetor Adjustment" section of engine
manual.

CLUTCH ROD ADJUSTMENT {Self Propelled Models
Only)

To adjust the clutch rod, refer to step numbers 15 and
