Finishing Work; Cutting Height Adjustment - Grillo HWT 700 SUPERTRAC Manuel D'utilisation

FINISHING WORK

Once work is ended, switch the engine off by setting the throttle lever back into the STOP position
(fully rearwards - fig. 4).
CAUTION: If the machine is to be parked on a slope always engage the parking brake (fig. 2, n. 9).
CAUTION: never leave the machine unguarded or in a place where children or inexperienced people
could have easy access to it.
REPLACING THE STRINGS
Replace the strings when worn out (fig. 1, n. 18).
CAUTION: Never replace the strings with the engine running.
The cutting diameter is of 60 cm. Check the length of the strings before replacing them and make sure
they do not come in touch with the machine while rotating (fig. 7).

CUTTING HEIGHT ADJUSTMENT

To adjust the cutting height, insert the strings in the holes at various heights (fig. 8, pos. A-B-C-D). In
position D the string works very low to the ground. This is the ideal position to remove weeds from
paving stones. If the ground is very uneven, set the strings at the highest position. To set the string
holder at position C and D use the appropriate screw (fig. 7, n. 24).
TROUBLESHOOTING
The following is a list of small problems which may occur during the use of the wheeled trimmer, which
the operator himself can remedy.
1)
2) If the engine does not start:
- the fuel tank must be at least half full (fig. 3, n. 12)
- if the engine is cold the choke must be engaged (fig. 4)
- the fuel must reach the carburettor
- the vent hole on the tank cap must not be blocked.
- the carburettor nozzles must be clean. To check them, unscrew and clean them with an air jet if
dirty.
- the plug must provide a spark. To check if it works, remove the plug reconnect it to the power
supply cable, rest the metal part on an electrical ground and turn the engine pulley as if to start it. If
no spark is seen between the two electrodes, try checking the plug cable connections and if power
is still not received, replace the plug. If the new plug still fails to work, the problem is in the
electrical system and you should contact your nearest service centre or authorized dealer.
2) If the engine is running but the wheeled trimmer does not move forward correctly:
- check that the left red lever if fully pressed (fig. 2, n. 5). If necessary adjust the wire (fig. 2, n. 6).
- make sure that the belt has not come out of its position on the pulleys. To check it remove the
cover below the machine (fig. 7, n. 19).
- Should the problem not be solved, increase the belt tensioning by shifting the engine of a couple
of mm towards the handlebar, loosening the three screws on the engine flange (fig. 10, n. 23).
3) The strings do not rotate properly:
- check that the right red lever if fully pressed (fig. 2, n. 2). If the strings do not turn, use the wire
adjusting screw (fig. 3, n. 4).
- make sure that the belt has not come out of its position on the pulleys. To check it remove the
front green cover of the machine (fig. 1, n. 21) and the cover below the machine (fig. 1, n. 19).
