Harness

CAUTION! It is very important to famil- iarize yourself with the release mecha-

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
7	14 15	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 deteriorate in time, so you should only prepare as much mixture as you are going to need (the use of deteriorated 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.

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. The safety pole guard should be mounted using the accessories supplied and in the configura- tion 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. Assembly of safety guard

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 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 diame- ter.

•For correct 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) with the cutting edge facing towards the outside of the shield, and fasten it with the screw (E) (Make sure the screws are tightened all the way (E) and are not loosened by the vibrations. If necessary, tighten them again).

CAUTION! If you are using the grass cut- ting blade, remove the extension (B) on the guard (A).
