6.2 Setting the cutting height
Fit the carrying strap as shown in Figures 8a-8c.
Hook the equipment to the carrying belt (Fig. 8d).
Adjust the perfect working and cutting position
using the various strap adjusters on the carrying
strap (Fig. 8e).
In order to establish the optimum length of the
carrying strap, you should then make a few
swinging movements without starting the engine
(Fig. 9a).
The carrying strap is fitted with a quick-release
mechanism. Pull the red strap section (Fig. 8f) if you
need to remove the strap quickly.
Important: Always use the strap when working with
the equipment. Attach the strap as soon as you have
started the engine and it is running in idle mode.
Switch off the engine before you take off the carrying
strap.
Check the equipment for the following each time
before use:
That there are no leaks in the fuel system.
That the equipment is in perfect condition and
that the safety devices and cutting devices are
complete.
That all screws are securely fastened.
That all moving parts move smoothly.
6.3 Fuel and oil
Recommended fuels
Use only a mixture of unleaded petrol and special 2-
stroke engine oil. Mix the fuel mixture as indicated on
the fuel mixing table.
Important: Do not use a fuel mixture which has been
stored for longer than 90 days.
Important: Never use 2-stroke oil with a
recommended mixing ratio of 100:1. The
manufacturer's warranty will be voided in case of
engine damage due to inadequate lubrication.
Important: Only use containers designed and
approved for the purpose to transport and store fuel.
Pour the correct quantities of petrol and 2-stroke oil
into the mixing bottle (see scale printed on the bottle).
Then shake the bottle well.
