Section 3 - MAINTENANCE
3.1 INTRODUCTION
To retain the quality of the mower, use genuine
SNAPPER replacement parts only. Contact a local
SNAPPER dealer for parts and service assistance.

5. If the rear wheels rotate, increase belt tension by rotating the thumb screw COUNTER-CLOCKWISE.
6. Turn thumb screw one turn at a time and recheck tension (repeating steps 3-5).
7. When proper belt tension has been set, operate machine and verify proper wheel drive control function.
IMPORTANT: DO NOT over-tighten wheel drive control. DO
NOT operate if control or drive does not function properly.
Contact your local SNAPPER Dealer for assistance.
IMPORTANT: If machine creeps forward after wheel drive control is released the cable is too tight and must be readjusted to eliminate all forward movement.

This is the exclusive remedy. Liabilities for consequential damages, under any and all warranties are excluded.
Some states do not allow limitations on how long an implied warranty lasts, or do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.
