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 L8RTF 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 (Fig. 16)

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

risk of kickback. Check mower blades for

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
