5.1 PERIODIC MAINTENANCE

5.1.1 Check the engine oil level:

Service Interval: Daily

a) Make sure unit is on a level surface, stop engine, and wait for all moving parts to stop.

b) Engine should be cold before checking engine oil.

c)Clean area around dipstick. Remove dipstick and wipe oil off. Reinsert the dipstick. Do not screw into

place. Remove the dipstick and read the oil level.

d)If the oil level is low, add oil to bring the oil level up to the “FULL” mark on the dipstick. Use oil as

specified in the Engine Owner’s Manual.

Do not overfill.

IMPORTANT: DO NOT operate the engine with the oil level below the “LOW” (or “ADD”)

mark on the dipstick, or over the “FULL” mark.

5.1.2 Clean engine cooling system:

Service Interval: Daily or more often in dry conditions

POTENTIAL HAZARD

·Excessive debris can cause the engine and hydraulic system to overheat.

WHAT CAN HAPPEN

·Excessive debris around the engine cooling air intake and inside of the pump

compartment can create a fire hazard.

HOW TO AVOID THE HAZARD

· Clean all debris from around the engine and hydraulic pumps daily.

a) Stop engine, wait for all moving parts to stop, and remove the key.

b) Clean all debris from engine air intake screen and from around engine shrouding.

5.1.3 Check battery charge:

Service Interval: Monthly

Allowing batteries to stand for an extended period without recharging them will result in reduced

performance and service life. To preserve optimum battery performance and life, recharge them in

storage when the open circuit voltage drops to 12 Volts.

Note: To prevent damage due to freezing, battery should be fully charged before putting mower away

for winter storage.

a) Check the voltage of the battery with a digital voltmeter. Locate the voltage reading of the battery in the

table (See chart 3.3.2 ) and charge the battery for the recommended time interval to bring the charge up

to a full charge of 12.6 Volts or greater.

IMPORTANT: Make sure the negative and positive battery cables are connected correctly, and the

battery charger used for charging the battery has and output of 16 volts and 7 amps or less to avoid

damaging the battery. (see chart 3.3.2 for recommended charger settings)
