nism. In case of emergency you need to be able to release the machine quickly.

The harness is equipped with a fasten-release mechanism. The harness enables the operator to support the machine during use (see “Safety pre- cautions”, B7).

 

 

D. Fuel Mixture

Preparation of the mixture

Filling the tank

14 15

Do not use any other type of fuel than the type recommended in this manual. This

machine is equipped with a two-stroke engine and should therefore be fueled with a mixture of unleaded gasoline (with a minimum octane rating

=90) and fully synthetic oil specific for two-speed engines that use unleaded gasoline in the propor- tions indicated in the table on the cover, fig. D.

Control the specifications of the oil shown on the package; the use of oil lacking the specifications expressly indicated in this manual

could cause serious damage to the engine!

To obtain the best mixture, pour the oil into an approved container first, followed by the gasoline, and shake the container well (every time you take fuel out of it).

The characteristics of the mixture tend to deterio- rate in time, so you should only prepare as much mixture as you are going to need (the use of dete- riorated fuel can seriously damage the engine).

Clean the area around the fuel cap before remov- ing it, to prevent any impurities from contaminat- ing the fuel. Take the cap off the fuel container carefully. Unscrew the cap on the fuel tank and fill it with the necessary quality, using a funnel. During use, to prevent problems in starting the engine again, we strongly recommend that you avoid letting the fuel run out in the tank.

Fuel storage

14 15

Store the fuel in a cool, well-ventilated place, in an approved fuel storage container.

Never store the engine with fuel in the tank in a poorly ventilated place where the fumes produced by the gasoline could propagate and reach a fire, candle, burner or furnace pilot light, water heater, dryer, etc. Never store excessive quantities of fuel.

E. Assembly/disassembly

E1. Delta grip

2 3 4

For your safety, fasten the delta handle in front of the label placed on the shaft at a distance of at least 18 cm from the rear grip. The handle should be fastened in a comfortable working position. If you are using sawtooth blades, the grip distance should be moved by at least 44 cm. The safety pole guard should be mounted using the acces- sories supplied and in the configuration shown in the figure,in contact with the delta handle.

E2. Double Handle

Adjust and secure double hand clamp by tighten- ing the screws.

E3. Fitting guard on line cutter head and grass cutting blade

2 3 4

Fit the safety guard (A) against the gearbox (I)

position the lower clamp (G) in the housing under the shield and the upper clamp (F) over the shaft. Insert and tighten the screws (H).

Safety guard extension (exclusively for use with nylon string head)

The string cutting blade housed in the plas- tic shield will cut the nylon string to opti-

mum length; a string that is too long reduces the rotation speed of the engine and interferes with cutting efficiency, as well as increasing the risk of injury.

The extension (B) should be installed only for use with the nylon string head, with the aid of the string cutter blade (L), that regulates the length of the string and thus the cutting diameter. For cor- rect assembly see the illustration on the cover and perform the following sequence of steps: Insert the extension (B) on the safety guard (A) at the reference notches (C), and fasten with the screws (D), then apply the string cutter blade (L)
