Operators Manual ES-650PIA

Throttle Lever

Set the throttle lever for starting the engine to full throttle 

position  and  additionally  close  the  starter  flap  on  the 

engine at cold start (CHOKE).
The best suction power can only be achieved with maxi-

mum speed, therefore the throttle lever should be set to 

full throttle position during operation. 

Clutch Lever

Use the clutch lever to engage the drive of the machine. 

To do this, press the lever on the guide rail to move off. 

When you release the lever, the leaf and waste vacuum 

cleaner stops. The driving speed is controlled exclusively 

by the 6-speed transmission.

Attention:

Never block the clutch lever in any way.

Risk of injury.

Adjusting Spindle for Suction Trunk

The adjustment spindle for the infinitely variable height 

adjustment of the suction trunk is located on the left 

side of the unit.
Turn the spindle counter-clockwise to lower the suction 

trunk. A suction trunk height of 7.5 cm is generally con-

sidered ideal for dry suction material. Place the suction 

trunk lower in the appropriate position with wet or even 

wet and rotten material. The lowest setting is reached 

when the rubber apron reaches the floor. It is not advis

-

able to make a lower setting, as it does not improve the 

suction power and can damage the suction trunk.
Too high setting reduces suction power.

Important:

Adjust the suction trunk as high as possible. Too low 

a setting can cause damage to the suction trunk and 

does not improve suction performance.

Important Information:

The driving speed must not be controlled by 

the clutch lever. If the clutch lever is not pulled 

through to the handle. the drive belt grinds 

and therefore wears out very quickly.

Gear Shift

The manual transmission offers a choice of 6 forward 

and one reverse gears. Usually, suction is done in 3rd 

or 4th gear. Slower speeds are recommended for difficult 

work or terrain. 
Engage the desired gear and press the clutch lever to 

start driving.

Important:

Never operate the gear shift without clutch. 

Release the clutch lever to change gear.
