INSTALLATION

!

!

 WARNING! The manufacturer is not liable for any direct and/

or indirect damage caused by incorrect installation.

TRANSPORT

Always use the packaging when transporting the machine; this will 

protect it from impact, dust and humidity which can compromise 

normal operation.

During transportation, unhook the box, disconnect the spark plug cap, 

fold the upper part of the handle over the engine (after loosening the 

fastening handwheels) and completely empty the fuel tank.

Lift the machine with a second person to help you, never by yourself, 

keeping it horizontal. If transporting on a vehicle, secure the machine 

using tensioning straps in order to prevent sudden movements due to 

braking, driving around corners, driving over bumps, etc.

HANDLING

Carrying the machine over a non-grassy area must always be done 

with the engine off, pushed by the user. It is possible to keep the 

engine on over already cut grass, and take advantage of the drive 

(where fitted), though it is possible that passage of the lawnmower 

may “mark” the grass with an unattractive result.

SWITCHING ON

When choosing where to use the machine, the following should be 

considered:

• that there is no bad weather, such as rain or storms.

• that there should be a large operational area free from obstacles.

• that the area is well lit with natural or artificial light.

• That the turf is suitable for mowing and the grass is not excessively 

tall, that it is not wet, and that it is free of rocks, protruding tree roots, 

branches, pipes, electric cables, objects, etc. that would damage 

the machine and endanger the user.

• that unauthorised personnel, children and pets are not present.

ASSEMBLY

!

!

 WARNING! Before carrying out the following operations, ensure 

that the spark plug cap is disconnected.

Take the machine and its components out and visually ensure that 

they are in perfect condition.

THROTTLE CONTROL AND HANDLE ASSEMBLY (fig. C)

1. Fig. C1: Remove the lower handle (pos. 5) and fasten it with screws 

(pos.7) to the two plates (pos. 6) of the machine, to the right and 

left of the rear door (pos. 14). In some models, there is more than 

one position for fastening the lower handles, for adjusting the final 

height of the upper handle. The shields and control cables must be 

positioned above the handle. Note: the lower handle may consist 

of two parts, rather than just one.

2. Fig. C2: Take the upper handle (pos. 1) and position it at the end 

of the lower handle, aligning the fixture holes.

3. Fig. C3: Screw the handwheels (pos. 7) keeping the cable sheaths 

above the handle. If the hardware is quick release (handwheel and 

lever), then screw the handwheel without tightening and then tilt the 

lever by 90°. Insert the clamps (pos. 8) above the handles in order 

to secure the sheaths and control cables.

4. Fig. C4: Insert the threaded part of the ring support (pos. 9) for the 

starter handle (pos. 10) on the hole on the right side of the upper 

handle and slightly tighten the nut. Now, grip the starter handle 

located above the engine, slowly pull it up to the support and insert 

the cord inside the ring. At this point, tighten the nut all the way and 

release the handle, which will stay on the freshly installed support.

5. Fig. C5: Install the gas control lever (pos. 4) on the hole in the 

left side of the upper handle and tighten the nut all the way. Do a 

test run and by operating the lever back and forth, the lever should 

move freely.

ASSEMBLY OF THE GRASS COLLECTION BOX (Fig. D)

!

!

 WARNING! Hooking and unhooking the grass collection box 

while using the lawnmower must only take place while the engine 

is switched off, with the blade completely still and the spark plug 

cap off.

1. Fig. D1: Lift the rear door (pos. 14) and keep it open. Note that in 

the grass collection box (pos. 15) there are protruding ends that
