Grillo HWT 550 TILT [11/44] Implements

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 SAE 10W30 oil.

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 blocked, it must be replaced (fig. 5).

Check periodically that the fins of the cylinder head and cylinder are not blocked; 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
