gloves during maintenance operations. Do not 
carry out maintenance with the engine hot.

AIR FILTER

Every 8-10 working hours, remove the cover (A, 
Fig. 19), clean the filter (B).
Blow with compressed air, at a distance.
Replace if dirty or damaged. The engine runs 
irregularly if the filter is clogged, with consequent 
higher consumption and lower performance.

FUEL FILTER

Check fuel filter periodically. A dirty filter can cause 
difficult starting and lower engine performance. 
To clean filter proceed as follows: remove it from 
fuel filling hole. Replace it (Fig. 17) if too dirty.

ENGINE

Clean cylinder fins with a brush or compressed 
air periodically. Dangerous overheating of engine 
may occur due to impurities on the cylinder.

SPARK PLUG

Clean spark plug and check electrode distance 
periodically (Fig. 18). Use TORCH L6RTC or of other 
brand with the same thermal grade.

GEAR HOUSING

Every 30 working hours, remove screw (D, Fig. 6) 
on the gear housing and check the quantity of 
grease. Do not use more than 10 grams. Use high 
quality molybdenum bisulfide grease.

Never use fuel for cleaning operations.

TRASMISSION

Grease the joints of the rigid tube (D, Fig. 20) every 
30 working hours with molybdenum disulfide.

CARBURETOR

Before adjusting the carburetor, clean the air filter 
(B, Fig. 19) and warm up the engine. 

Idle screw T is adjusted in order to ensure a good 
safety margin between idle running and clutch 
engagement.

BLADE SHARPENING (2-3-4 TOOTH)

1.  Blades are reversible: when one side is no 

longer sharp, the blade can be turned over 
and used on the other side (Fig. 13).

2.  Blades are sharpened using a flat single-cut 

file (Fig. 13).

3.  To maintain the correct balance, file all cutting 

edges uniformly.

4.  If the blades are not sharpened correctly, this 

can set up abnormal vibrations in the machine 
and cause the blades themselves to break 
ultimately. 

WARNING! – 

The wrong type of cutter or 

an incorrectly sharpened blade will increase the

deterioration or cracks, and replace if damaged.

WARNING: Never repair damaged 

cutting attachments by welding, 
straightening or modifying the shape. This 
may cause parts of the cutting tool to come 
off and result in serious or fatal injuries.

NYLON LINE HEAD

Only use line of the same diameter as the original 
to avoid overloading the engine (Fig. 14). 
In order to get more line out of the cutting head, 
tap it lightly on the ground while working.

Note:

 Never hit the nylon head against hard spots 

such as concrete or stones, it could be dangerous.

Replacing the nylon line on the TAP&GO 
trimmer head (Fig.15)

1   -  Press the tab (1, Fig. 15) and remove the cover 

and the internal spool.

2  -  Double back the line, leaving one end 14 cm 

longer than the other one. Lock the line in the 
notch (2, Fig. 15). Wind the line in the direction 
of the arrow, each end in its chink, regulary, 
without crossing them.

3  -  At the end of the winding, lock in the slits (3, 

Fig. 15) Assemble the spring. Thread the line 
through the eyelets (4) (fig.15), secure the 
head with the cover (5) and then pull the line 
outwards from the head (6).

WARNING! – Always wear protective
