6.4 BATTERY DISPOSAL

DANGER

POTENTIAL HAZARD

♦Battery electrolyte contains sulfuric acid, which is poisonous and can cause severe burns

WHAT CAN HAPPEN

♦Swallowing electrolyte can be fatal or if it touches skin can cause severe burns.

HOW TO AVOID THE HAZARD

♦Wear safety glasses to shield eyes, and rubber gloves to protect skin and clothing when handling electrolyte.

♦Do not swallow electrolyte.

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.

7.TROUBLE SHOOTING

7.1MOWER PULLS LEFT OR RIGHT (W/LEVERS FULLY FORWARD).

a)Refer to Tracking Adjustment Section 4.1.3.

b)Check air pressure in tires; 13 psi/drive, 13 psi/pneumatic casters.

Note: Some units have semi-pneumatic casters (without a valve stem) which do not require inflation.

c)Check reverse indicator and motion control linkage adjustment. See section 5.2.12 and 5.2.13.

7.2MOWER CUTS UNEVENLY.

a)Check air pressure in tires; 13 psi/drive, 13 psi/pneumatic casters.

Note: Some units have semi-pneumatic casters (without a valve stem) which 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. Higher pressures in front casters may cause them to shimmy on hard surfaces.

b)Check deck support chains.

c)Check deck leveling (See Adjustments Section 5.2.2.)

Note: The front of the mower deck will be approximately 1/4” lower than the back of the mower deck. This is the “rake” of the deck.

d)Check blades tip to tip for straightness (they should be within 3/16" or one blade width from being in line.)

7.3ENGINE WILL NOT START.

a)Make sure the battery has a full charge. See section 5.1.3 for charging instructions.

b)Be sure the throttle control is midway between the “SLOW” and “FAST” positions, and the choke is in the “ON” position for a cold engine or the “OFF” position for a warm engine.

c)Make sure there is fuel in the fuel tank and that the fuel valve is open.

d)Be sure the seat switch is properly adjusted. See Section 5.2.6.
