Maintenance
Maintain the chipper with care and keep it clean at all times.
To service or inspect the equipment, or to change an accessory, you must:
✓ Switch the engine off
✓ Allow the chipper to cool before any inspections or adjustments
✓ Wait until the cutting rotor and engine are at a complete standstill before opening the cutting
rotor housing
✓ Disconnect the spark plug wire from the spark plug
✓ Switch fuel lever to off position
Initially after 2 working hours:
✓ Check for any loose nuts and bolts
✓ Check belt tension (refer to belt tension section)
The belts will stretch when they are new
✓ Grease the two rotor bearings, one on the inside and one on the outside of the housing
One or two pumps are sufficient
Be careful not to over grease
The bearings are already greased when the equipment is new
Use bearing grease or all-purpose grease
Every 20 working hours:
✓ Check for any loose nuts and bolts
✓ Check belt tension (refer to belt tension section)
✓ Grease two bearings as above, be careful not to over grease
✓ Check sharpness of knives
✓ Check condition of guarding (belt guard and outlet chute)
A damaged guard must be replaced by an identical or equivalent guard immediately
It is recommended to contact Hansa for a replacement guard.

Material comes out in long strips
Blunt knives will cause excessive vibration

arrange re-sharpening.
