Keeping Engine Clean

Remove all grass and debris from the engine including

use. Never spray the engine with water during cleaning.
Water can contaminate the fuel. Always clean with a
brush or compressed air.
Grass and debris may clog the engine's air cooling
system especially after prolonged operation while cutting

damage. We recommended that this service be carried
out by an authorised Hayter Service dealer.

Grassbag

Remove grass debris from the grassbag immediately
after use and check its condition for signs of damage.
To prevent accidents replace a damaged grassbag
immediately.
