NOTE: Operate the lift truck for 5 minutes or until the
transaxle is warm to the touch. Transaxle fluid will drain
easier and more thoroughly when it is warm. Each
transaxle uses separate, self-contained fluid supplies.
1. Remove drive tire and block lift truck frame to po-
sition transaxle at the same height and position as
with drive tire installed.

2. Turn key switch to OFF position and disconnect bat-
tery. Block thewheels to prevent unexpected move-
ment.
3. Place a drip pan with at least a 3.0 liter (3.3 qt)
capacity under transaxle.
CAUTION
Clean around plugs with solvent before removal to
prevent contamination of the transaxles.
4. Remove fill plug on transaxle. Inspect breather for
proper operation. Clean or replace as necessary.
See section Breather Repair.
5. Remove check plug.
6. Remove drain plug. Clean drain plug thoroughly,
removing any metallic debris that has collected on
drain plug magnet.
CAUTION
Disposal of lubricants and fluids must meet local
environmental regulations.
CAUTION
The drain plug must not be interchanged with the
fill or check plugs. Use only an approved magnetic
type drain plug to prevent damage to the transaxle.
NOTE: It may take as long as 10 minutes for the
transaxle to drain completely depending on temper-
ature and contaminants. Allow the transaxle to drain
completely before continuing.
7. After transaxle has drained completely, install drain
plug into transaxle as removed. Tighten to 22 N•m
(192 lbf in). Remove drip pan and dispose of waste
fluid properly.
NOTE: Use a funnel or a funnel with a tube attached to
add fluid to the transaxle. Pour slowly.
8. Fill transaxle with fluid until level with bottom of
check hole. Each transaxle should be filled with ap-
proximately 0.60 liter (0.63 qt) of fluid.
9. When fluid reaches bottom of check hole, install
check plug and fill plug and tighten each to 22 N•m
(192 lbf in).

BREATHER REPAIR

The breather can be repaired with the transaxle in-
stalled to the lift truck and the drive tire removed. The
breather equalizes air pressure inside the transaxle
with the air pressure outside. If the breather is visibly
damaged then the breather should be replaced.
1. Remove drive tire and block lift truck frame to po-
sition transaxle at the same height and position as
with drive tire installed.
