Maintenance Instructions CHECKING/SERVICING
Security of Air Filtration Components
NOTE: The following inspection is only an exter-
nal inspection and should be done without “dis-
turbing” the filtration components.
On a daily basis, visually inspect the external condi-
tion of the complete air cleaner system. The follow-
ing items should be inspected:
1. Check the Donaldson Radialseal™ air cleaner
canister for damage. Make sure the cover is in
place and the cover latches are secure - do not
run the engine without the air cleaner cover in
place and secure.
2. Inspect the air intake hose for cracks, nicks,
cuts, etc., and check the hose clamps for tight-
ness.
Battery
NOTE: For initial battery service during setup, re-
fer to Battery Service in Assembly Instructions.
IMPORTANT: Make sure battery is securely mount-
ed in the frame. A loose battery may cause damage
to the case resulting in acid leakage and severe dam-
age to the machine. A hazard may be created by
damage to critical working parts and safety systems.
Electrolyte Level
The battery electrolyte level should be checked af-
ter every 25 hours of operation. To check electro-
lyte level:
1. Remove battery cell filler caps.
2. Check the electrolyte level. If the level is below
the bottom of the vent well, fill with drinking wa-
ter to the bottom of the vent wells [1/4 to 1/2 in.
(6 to 13 mm) above the plates].
3. Replace filler caps.
IMPORTANT: DO NOT overfill the battery.
Electrolyte will overflow through the vented caps
onto parts of the machine and WILL result in se-
vere corrosion.
Cleaning the Terminals
If battery terminals are corroded, remove battery
from the mower. Using a wire brush, remove corro-
sion with a solution of one part baking soda and
four parts water. Rinse with clean water. Coat the
terminals with petroleum jelly or terminal protector
spray to retard further corrosion.
Charging the Battery
Check the battery charge by measuring the specific
gravity of electrolyte; if specific gravity is less than
1.225, the battery will need to be charged as follows:
1. Charge the battery at 15 amps for 10 minutes.
DO NOT exceed 20 amps maximum recom-
mended charging rate. Charge until specific
gravity is at least 1.250. Total charging time
should not exceed one (1) hour.
2. After charging the battery, use drinking water to
adjust the electrolyte level to the bottom of the
vent wells [1/4 to 1/2 in. (6 to 13 mm) above the
plates].
Tire Pressure
Inflate tires to pressures shown below:
Deck Caster Wheel = 20 PSI (137 kPa)
Drive = 15 PSI (103 kPa)
Rear = 20 PSI (137 kPa)
DANGER
BATTERIES PRODUCE EXPLOSIVE
GASES
• Charge the battery in a well-ventilated
area, so that gases produced while charg-
ing can dissipate.
• Keep sparks, flames, and smoking ma-
terials away from the battery at all times.
• Make sure the battery cap vents are open
(check manifold vent on each cap).
• Make sure the battery charger is un-
plugged before connecting or discon-
necting cables to the battery.
