Grass-Cutting - CARPI C 34 DS Manual De Instrucciones Y Mantenimento

GB
Fit the bottom band with knife to the guard. Do not
use very worn heads: some components may
come off and put the operator in danger.
REPLACING THE
HEAD LINE
To replace the line, follow the instructions enclo-
sed with the head being used.
WARNING Never replace the nylon line with a
line made of any other material (e.g. iron).
PRECAUTION
Do not use line with a diameter greater than 3 mm.
Line that is too thick may impede the performance
of the motor by generating an excessive load.
Line with a diameter lower than 2.4 mm produces
mediocre results and wears out rapidly.
The flexibility of the line will improve if it is left in
water 1 - 2 days before it is used..
SHARPENING 3- OR 4-POINTED DISKS
Sharpen with a suitable flat file (Fig. 21).
Figure 22A and 22B show:
A ) The wrong way to sharpen
B) Sharpening limits
C) Wrong or unequal angles
All the points have to be sharpened in the same
way.
Both sides of the 3- and 4-pointed disks can be
used. When one side is worn, the disk can be tur-
ned over in order to use the other side.

GRASS-CUTTING

WARNING Remove the spark plug cap before
sharpening.
Put on a pair of gloves before sharpening to avoid
cutting yourself. It is important to ensure the machi-
ne is correctly balanced even after sharpening.
The metal disk must never be repaired: the disk
must be replaced as soon as you notice any brea-
kage or if the sharpening limit has been exceeded.
SHARPENING THE SAW DISK
Check that the blade setting is about 1 mm.
If necessary, adjust it with pliers (Fig. 23).
Sharpen the blade with a 5.5 mm diameter round
file. Approach the blade with the file as per Fig. 24.
Sharpen the left tooth and the right tooth alterna-
tely. Sharpen all the teeth equally.
If the blade is damaged, the top part of the tooth
may also have to be sharpened. Use a suitable flat
file and sharpen all the teeth equally (Fig. 25).
The profile of the tooth must not be changed.
WARNING Remove the spark plug cap before
sharpening.
Put on a pair of gloves before sharpening to avoid
cutting yourself on the blade.
The circular saw disk must never be repaired: the
disk must be replaced as soon as you notice any
breakage or if the sharpening limit has been excee-
ded.
If the blade is not sharpened properly, it may cause
the machine to recoil. Furthermore,
an insufficient setting will also cause recoil.
It is important to ensure the machine is correctly
balanced even after sharpening.
