Cutting techniques

During the cutting operations, keep the engine running at high speed. After every

cutting stage, decelerate the engine to minimum speed as running it at top speed without a load can damage the engine severely.

Wait until the engine is running at minimum speed before moving the machine from one section to another.

The machine is ideal to complete the work of the lawnmover. In fact, it can reach places where a normal lawnmower is unable to go.

Cutting and trimming grass borders with the nylon string head

Cutting with the nylon string head is suitable for light jobs like trimming borders and cutting the grass around trees.

Mowing

To prevent damage to your lawn or the cutting mechanism, keep the string parallel to the ground but avoid contact with the terrain.

Trimming borders

Angle the nylon string head keeping it a short dis- tance from the ground. Cut using the end of the string. Do not press the string against the material to be cut.

I1. Drawing out the string (A)

During cutting, the nylon string wears naturally causing an increase in the speed of the engine and a reduced cutting capacity. When this hap- pens, to bring out more string bump the head against the ground: release the throttle trigger to reduce the engine speed to less than 8000 rpm.

Tap gently on the ground with the button (A) as shown in the figure and the string will come out automatically. Accelerate again. If the string does not come out make sure there is still some left and try again.

I2. Drawing out the string (B)

In order to extend the nylon line as it wears down, pull the mower gauge downwards and turn it in a clockwise direction to feed out the desired length of line.

I3. Thinning grass with the grass cutter blade

2 16

The grass is cut with swinging motions from side to side, maintaining the blade parallel to the ground. During the right to left swing the grass is cut, while the backswing must be made without using the blade.

KICKBACK can occur when cutting is done with the risk sector of the blade; we recommend cut- ting with the rest of the blade. Take care that the cup supporting the blade just grazes the ground. This will prevent the blade from touching the ground.

Use of sawtooth blade

2 5 11 16

Do not attempt to cut trees with a larger than recommended diameter, to prevent

the risk of kickback or damage to the blade.

The sawtooth blade serves to cut bushes and small trees, with maximum diameter of seven centimeters. Rest the left side of the special shield on the trunk while cutting to limit the risk of losing control of the machine.

L. Environmental information

This section contains information useful for main- taining the characteristics of eco-compatibility included in the origin design of the machine, and as regards proper use and disposal of oil and fuel.

Design

In the design stage, care was taken to develop an engine with reduced consumption and low emis- sions of noise and pollutant exhaust fumes.

Use of machine

The operations of filling the tank with the fuel mix-

ture should be carried out in such a way as to avoid spilling fuel and contaminating the soil and environment.

Periods of prolonged disuse

Always empty the fuel tank with the same precau- tions used in filling it.

Disposal

Do not dispose inappropriately of the machine when it is no longer usable. Deliver it to an authorized organization for proper disposal in compliance with the regulations in force.
