5. WASTE DISPOSAL

5.1 MOTOR OIL DISPOSAL

Engine oil and hydraulic oil are both pollutants to the environment. Dispose of used oil at
a certified recycling center or according to your state and local regulations.

5.2 BATTERY DISPOSAL

Federal law states that batteries should not be placed in the garbage. Management and
disposal practices must be within relevant federal, state or local laws.
If a battery is being replaced or if the unit containing the battery is no longer operating
and is being scrapped, take the battery to a local certified recycling center. If no local
recycling is available, return the battery to any certified battery reseller.

6. TROUBLE SHOOTING

6.1 MOWER PULLS LEFT OR RIGHT (WITH LEVERS FULLY FORWARD).
a) Refer to Tracking Adjustment Section 3.1.3.
b) Check air pressure in drive tires; 13 psi.
Semi-pneumatic casters do not require inflation.
c) Check reverse indicator and motion control linkage adjustment. See
Section 4.2.9 and 4.2.10.
6.2 MOWER CUTS UNEVENLY.
a) Check air pressure in drive tires; 13 psi.
Semi-pneumatic casters do not require inflation.
A more uniform cutting height may be obtained with higher tire pressure on
rough terrain. A lower tire pressure provides more flotation.
b) Check deck support chains.
c) Check deck leveling (See Adjustments Section 4.2.2.)
