Maintenance And Lubrication - Grillo HWT 375 Uso Y Mantenimiento

MAINTENANCE AND LUBRICATION

Effective maintenance and correct lubrication help to keep the bush-cutter always in perfect working
order.
4-STROKE ENGINE – For lubrication procedures, follow the instructions provided in the engine manual.
As a general guide, the oil level should be checked every 4 working hours and changed every 50 hours.
Always use AGIP F1 GAMMA SAE 30 oil (for the 2-stroke engine follow the instructions in the proper
engine handbook).
For the air filter, check the cartridge every 8 hours or even more often if the environment is very dusty.
Do not clean the cartridge with air jets; if fouled, it must be replaced.
Check periodically that the fins of the cylinder head and cylinder are not fouled; remove the
relative guards and follow the instructions in the engine manual.
USEFUL HINTS FOR GOOD PERFORMANCE:
1. Never leave the machine in the rain.
2. Never strain the engine too much; excessive smoke from the exhaust pipe means it is labouring; slow
down.
3. Clean the air intake filter frequently;
4. Remove any grass deposits from the engine ventilation grille;
5. Square-section strings or other sections with sharp edges should be used; cutting requires less effort.
6. If the engine starts to labour, use shorter strings.
SPARE PARTS WHICH SHOULD BE KEPT TO HAND
- Cutting head strings, length 53 cm;
- 2 blade clutch wires;
- 2 travel clutch wires (for HWT 600 WD only).
HOW TO ORDER SPARE PARTS
Contact our parts centres located in every area; always state the machine's serial number and the code
number of the piece to be replaced.
IMPLEMENTS
SAW DISC
This implement, (fig. 10) specially developed for this type of machine, is very useful for cutting bushes
or small trunks.
It is fitted instead of the cutting head, using the M8 screw, fig.11 - 12.
Screw the two tubular guides onto the side, using the threads provided.
GRASS-SCREEN PROTECTION
This protection (fig. 13) is advised for the grass removal in the streets or avenues edges, in order to avoid
the grass to be thrown away.
