Adjusting The Cutting Height - Grillo HWT 550 TILT Manuel D'utilisation

ADJUSTING THE CUTTING HEIGHT

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 is flush with the ground. This is the ideal position in order to remove weeds from
paving stones. If the ground is very uneven, set the strings in the highest position. To set the string
plate in position C and D adjust the screw under the cup.
WHEEL AXLE ROTATION (HWT550 TILT model)
Model HWT550 TILT is provided with three working positions: central, right or left. The lateral
movement is very useful when working close to walls and pavements. To tilt the wheel axle proceed
as follows:
- slightly raise the wheel above the ground, press the position pedal down and move the wheels (fig.
3).
TROUBLESHOOTING
The following is a list of small problems which may occur during the use of the TRIMMER brush-
cutter, which the operator himself can remedy.
1) If the engine does not start (petrol engine) carry out the following checks
- the fuel tank must be at least half full.
- the fuel tap must be turned on.
- if the engine is cold the choke must be engaged.
- 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) For HWT600: If the engine is running but the wheeled trimmer does not move forward
correctly, perform the following checks:
- check that the lever if fully pressed (fig. 2, no. 9). If necessary adjust the wire (fig. 2, no. 10).
- make sure that the belt has not come out of its position on the pulleys. To check it remove the
cover below the machine.
- 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.
3) The strings do not rotate properly:
- check that the lever if fully pressed (fig. 1, no. 2). If the strings do not turn, use the wire
adjusting screw (fig. 3, no. 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 and the cover below the machine.
- 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.
