a warranty repair must have prior ap-
proval before conducting maintenance

EXTERNAL MAINTENANCE
Reference Table 4., Page 13 for tools required
in the maintenance of the 310-3000 IHT.
Regular external maintenance of the 310-3000
IHT should include the following:
1. Check the vehicle operator’s manual for the
recommended load ratings. Insure the cur-
rent application does not exceed load rating.
2. Check oil level See Figure 3, Page 7.
3. Inspect the vehicle drive belt, idler pulley(s),
and idler spring(s). Insure that no belt slip-
page can occur. Slippage can cause low in-
put RPM to the transaxle
4. Inspect the transaxle cooling fan for broken
or distorted blades and remove any obstruc-
tions (grass clippings, leaves dirt, etc.).
5. Inspect the axle parking brake and vehicle
linkage to insure proper actuation of the park-
ing brake.
6. Inspect the vehicle control linkage to the di-
rectional control arm on transaxle. Also, in-
sure the control arm is securely fastened to
the trunnion arm of the transaxle.
7. Inspect the bypass mechanism on the
transaxle and vehicle linkage to insure it ac-
tuates and releases fully.
