Exmark FMD604 manual Service Interval After First 250 hrs, then yearly thereafter

f)Start the engine and check for leaks. Stop engine and recheck oil level.

5.1.8Check the battery charge.

Allowing the 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 batteries in storage when the open circuit voltage drops to 12.4 volts.

Note: To prevent damage due to freezing, battery should be fully charged before putting away for winter storage.

Check the voltage of the battery with a digital voltmeter. Locate the voltage reading of the battery in the table below 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 battery cables are disconnected and the battery charger used for charging the battery has an output of 16 volts and 7 amps or less to avoid damaging the battery (see chart below for recommended charger settings).

Voltage	Percent		Maximum		Charging Interval
Reading	Charge		Charger Settings
12.6 or greater	100%		16 volts/7 amps	No Charging Required
12.4 – 12.6	75	– 100%	16 volts/7 amps	30 Minutes
12.2 – 12.4	50	– 75%	16 volts/7 amps	1	Hour
12.0 – 12.2	25	– 50%	14.4 volts/4 amps	2	Hours
11.7 – 12.0	0 – 25%		14.4 volts/4 amps	3	Hours
11.7 or less	0%		14.4 volts/2 amps	6	Hours or More

5.1.9Check hydraulic oil level. Service Interval: 40 hr.

a)Stop engine and wait for all moving parts to stop.

b)Clean area around hydraulic reservoir cap and remove cap.

c)Check hydraulic reservoir and if necessary fill the reservoir to the appropriate level with Mobil 1 15W-50 synthetic motor oil. Replace hydraulic reservoir cap and tighten until snug. Do not overtighten.

NOTE: The baffle is labeled “HOT” and “COLD”. The oil level varies with the temperature of the oil. The “HOT” level shows the level of oil when it is at 225°F (107°C). The “COLD” level shows the level of the oil when it is at 75°F (24°C). Fill to the appropriate level depending upon the temperature of the oil. For example: If the oil is about 150°F (65°C), fill halfway between the “HOT” and “COLD” levels. If the oil is at room temperature (about 75°F (24°C)), fill only to the “COLD” level.

5.1.10Change hydraulic system filter.

Service Interval: After First 250 hrs, then yearly thereafter.

Note: Use only Exmark P/N 1-513211 for Summer use above 32° F (0° C) or P/N 1-523541 for Winter use below 32° F (0° C). (Refer to Section 2.6.2 for filter specifications)

a)Place unit on a level surface. Stop engine, wait for all moving parts to stop, and remove key.

b)Carefully clean area around filter. It is important that no dirt or contamination enters the hydraulic system.

c)Unscrew filter to remove and allow oil to drain from reservoir.
