1. BLADE REDUCTION GEAR GUARD (Fig. 7)
– Lubricate every 20 hours through the grease
nipples provided.
– Only use lithium-based grease for high temper -
atures and extreme pressures.
2. MAINTENANCE AND SHARPENING
OF THE BLADE
DANGER! Periodically check that the
blades are not bent or damaged and that the
fixed comb on the blade is intact.
Adjustment of the distance between blades is not
necessary, as this is predetermined by the manu -
facturer.
If the blades are used correctly, following all the
instructions provided, they will not require any
maintenance work and will not need sharpening.
It is necessary to sharpen the blades only when
the trimming performance decreases and the
branches tend to stick together.
NOTE
Any intervention on the blade
should always be conducted at a specialised Cen-
tre that has the most appropriate tools and is able
to perform the operations without compromising
the safety of the machine.
Given the product evolution, the above mentio-
ned tools may be replaced in time by others, with
similar interchangeable and operating safety cha -
racteristics.
