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 tractor engine off
✓
Wait until the cutting rotor and engine are at a complete standstill before opening the cutting rotor housing
✓
Disconnect the PTO drive shaft from the tractor
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 at the front and one at the back of the housing) and the two PTO input shaft bearings
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 four bearings as above, be careful not to over grease
✓
Check sharpness of knives
✓
Check condition of guarding (belt guard, shaft guards, PIC 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
WARNING! Do NOT
open the housing unless the engine and cutting rotor have completely stopped.
WARNING!
Prior to starting any maintenance tasks on the PTO driven chipper, ensure the tractor is parked on a flat, level
surface with the park brakes applied, engine stopped, chipper placed firmly on the ground, and the PTO drive shaft
removed.
