Delivery and Dealer Service
Pre-delivery service
1. Top up battery with acid and recharge for four hours.
2. Fit the steering wheel, tow plate, and where appropriate other parts.
3. Adjust cutting unit:
- Adjust lift springs (effective weight of cutting unit should be 12–15 kg (26.5-33 lb), or set to maximum lift if brush is to be fitted). (Only applies to BioClip and Combi.)
- Adjust cutting unit so that rear edge is about 2–4 mm (1/8") higher than front edge.
- Adjust cutting unit height setting so that cutting height limit is 5 mm (3/16") above the frame of the unit at the lowest cutting height.
4. Check that engine has correct amount of oil.
5. Check that the right amount of oil is in the transmission. (Not Rider 11)
6. Check and adjust tyre pressure (60 kPa/0.6 bar/8.5 PSI).
7. Connect battery.
8. Fill with fuel and start engine.
9. Check that machine does not move in neutral. (Not Rider 11)
10. Check:
- Forward drive.
- Reverse drive.
- Operation of blades.
- Seat safety switch.
- Lift lever safety switch.
11. Check engine revs 2 900 - 3 100 rpm. Rider 16, 2003- model, 2 800-3 000 rpm.
12. Tell customer about:
- Need and benefits of following the service schedule.
- Need and benefits of having machine serviced every 300 hours.
- The effects of maintenance on the machine's second-hand value.
- Applications for BioClip and Combi.
13. Complete proof of sale, etc.
After first 5 hours
1. Change engine oil.
